'''Technologies''' are series of [[research]] projects that provide various enhancements. Some technologies unlock new items or recipes, while others provide bonuses.

Most technologies can be researched in [[lab]]s by consuming [[science pack]]s of various types. For example, the [[Logistics (research)|Logistics]] technology can be unlocked by placing 20 [[automation science pack]]s into labs while the technology is selected for research. Some technologies will automatically unlock after meeting specific conditions, without consumption of any science packs.

== Infinite technologies ==

While most technologies in Factorio are either one-off or have a finite, relatively small number of levels available, a few are "infinite", meaning the player can research as many levels as they can afford. All of them unlock bonuses to existing technologies, never new structures or abilities. The per-level bonuses are constant for a particular infinite technologies and, like finite research bonuses, are additive within a single technology. They are subject to diminishing returns; thus, the per-level and per-science pack contributions from very high levels of infinite technologies will eventually provide only marginal improvements.

All base game infinite technologies levels require [[space science pack]]s, and are also the only technologies that do. As such, they are late-game technologies intended primarily for players who wish to continue playing and expand their factory past the nominal victory condition of launching a rocket.

Infinite technologies are identified in-game by a small <code>∞</code> infinity symbol shown in the top right corner of the research technology's card in the research screen.

Most infinite technologies are continuations of ordinary multi-level technologies; the "infinite" mechanic becomes effective once the player reaches the card initially labeled with <code>N - ∞</code> in the research tree. In the base game, only the two [[artillery]]-related technologies (artillery shell [[artillery shell range (research)|range]] and [[artillery shell shooting speed (research)|shooting speed]]) are infinite-only; for these, <code>1 - ∞</code> is shown before any levels in them are researched. In either case, once the first infinite level is researched, the card label switches to the one discussed above.

=== Pricing formulas ===

The price of all infinite technologies is generated in a [[Wikipedia:Progression|mathematical progression]]; for the majority of technologies, the progression is [[Wikipedia:Geometric_progression|geometric]], mostly in powers of 2. Two technologies - [[mining productivity (research)|mining productivity]] and [[follower robot count (research)|follower robot count]] - use an [[Wikipedia:Arithmetic_progression|arithmetic progression]] instead.

The table below summarizes for all infinite researches their first infinite level, the cost of the first few infinite levels, the cost formula and the per-level bonus.

We denote by <code>N</code> the current level of the research, by <code>F</code> the final non-infinite level of the research (hence F+1 is the first "infinite" level) and by <code>P[N]</code> the price of the research at level <code>N</code>.

==== Space Age ====
The table below summarizes all the infinite technologies in Space Age. Some are unique to Space Age, while some have their price and/or effect changed from the base game.

Due to the introduction of [[Tesla weapons (research)|Tesla weapons]], the [[Energy weapons damage (research)|Energy weapons damage]] technology is split into [[Laser weapons damage (research)|Laser weapons damage]] and [[Electric weapons damage (research)|Electric weapons damage]].

=== Cumulative cost ===

As the price of most infinite technologies (specifically, those based on geometric progressions) increases very steeply, it may be a good idea for players to set realistic target levels for each of the infinite technologies they wish to pursue, and make their factory plans accordingly. To that end, the following properties of cumulative infinite research prices may be useful:

#For infinite technologies whose underlying equation is a powers-of-two geometric series, the cumulative price of the first <code>N - F</code> infinite levels (skipping the first <code>F</code> level, so counting "infinite" levels only) is <code>2 × P[N] - P[F+1]</code>; i.e., twice the price of the final researched level, less the price of the first "infinite" level.
#*As ''N'' increases, this is approximated well by <code>2 × P[N] = P[N+1]</code>, so the cumulative cost of researching to level <code>N</code> is about as much as researching level <code>N+1</code>.
#*If one decides a level <code>M</code> which one considers the "highest feasible" with their current science pack production capacity, expanding said capacity by a factor of <code>X</code> will allow about <code>log[2](X)</code> additional levels to be researched before the next level takes longer to research with the expanded capacity than level <code>M + 1</code> would have taken with the pre-expansion production capacity.
#*For example, if one expands production capacity by a factor of 10, they will be able to research at least <code>floor(log[2](10)) = 3</code> and at most <code>ceiling(log[2](10)) = 4</code> additional levels in a given technology before the exponential increase in price negates the speed benefits of their ×10 capacity expansion.
#The cumulative price of the first <code>N - F</code> levels of infinite technologies whose underlying equation is an arithmetic series is <code>(N - F) × (P[N] + P[F + 1]) ÷ 2</code>; i.e, <code>N - F</code> times the mean of the prices of the first and last "infinite" level. For the [[Follower robot count (research)]], an additional <code>900 × (N-F)</code> need to be added.
#*Expanding production capacity by a factor of <code>X</code>, as above, will in this case allow an additional <code>N × (X - 1)</code> levels to be researched before the benefit of the expansion is wiped out (i.e., research progress speed drops to or below what it was pre-expansion).
#The cumulative price of the first '''''N''''' levels of '''artillery shell shooting speed''', the sole infinite technology whose underlying equation is a powers-of-three geometric series (equation type (2)) is <code>1.5 × P[N] - 0.5 × P[1]</code>; i.e., 1.5 times the price of the final researched level, less half the price of the first level.

Note that these prices reflect '''research units''', which will not be equal to science packs if [[productivity module|productivity modules]] are used in labs. (In that case, the science pack requirement will be lower.)

=== Infinite productivity research limits {{SA}} ===

All recipes have a maximum productivity of 300%. This was [https://factorio.com/blog/post/fff-375 primarily done to prevent infinite resource exploits] involving the [[recycler]]{{SA}} and its 25% return of input items. This cap puts a hard limit on the effectiveness of most infinite productivity researches. You can research past level 30 of these technologies, but it will have no practical effects.

Note that miners are not crafting machines that execute recipes, nor are labs. As such, [[mining productivity (research)]] and [[research productivity (research)]]{{SA}} have no limit.

The [[Railgun shooting speed (research)|railgun turret's shooting speed]] is limited by its [https://forums.factorio.com/viewtopic.php?p=673363#p673363 animation], which means it can't shoot faster than 0.845 times per second (once per 71 [[Time#Tick | ticks]]). This shooting speed is reached at level 10 and researching past that level will have no practical effect on the railgun turret, however it '''will''' continue to increase the shooting speed of the hand-held [[railgun]].

The '''Railgun turret''' is a powerful late-game turret, unlocked with [[cryogenic science pack]]s{{SA}}.

The railgun turret has a limited firing arc of 72°. To compensate for this, it can be placed in one of 8 directions.

The turret does massive damage to all entities and structures in its line of fire. Any buildings in its firing arc are unlikely to survive (including [[wall]]s).

Railgun turrets are very effective against [[Asteroids|huge asteroids]], as the damage of [[railgun ammo]] easily beats their flat physical resistance. It is also quite useful against [[Demolisher]]s, especially when fired directly down their bodies, as shells can hit multiple segments at once.

[[File:Technology tree.png|thumb|right|280px|The technology tree − Click to enlarge.]]
[[File:tech_bonuses.png|thumb|right|280px|Researched tech bonuses.]]
'''Technologies''' are series of [[research]] projects that provide various enhancements. Some technologies unlock new items or recipes, while others provide bonuses.

Most technologies can be researched in [[lab]]s by consuming [[science pack]]s of various types. For example, the [[Logistics (research)|Logistics]] technology can be unlocked by placing 20 [[automation science pack]]s into labs while the technology is selected for research. Some technologies will automatically unlock after meeting specific conditions, without consumption of any science packs.

== Infinite technologies ==

While most technologies in Factorio are either one-off or have a finite, relatively small number of levels available, a few are "infinite", meaning the player can research as many levels as they can afford. All of them unlock bonuses to existing technologies, never new structures or abilities. The per-level bonuses are constant for a particular infinite technologies and, like finite research bonuses, are additive within a single technology. They are subject to diminishing returns; thus, the per-level and per-science pack contributions from very high levels of infinite technologies will eventually provide only marginal improvements.

All base game infinite technologies levels require [[space science pack]]s, and are also the only technologies that do. As such, they are late-game technologies intended primarily for players who wish to continue playing and expand their factory past the nominal victory condition of launching a rocket.

Infinite technologies are identified in-game by a small <code>∞</code> infinity symbol shown in the top right corner of the research technology's card in the research screen.

Most infinite technologies are continuations of ordinary multi-level technologies; the "infinite" mechanic becomes effective once the player reaches the card initially labeled with <code>N - ∞</code> in the research tree. In the base game, only the two [[artillery]]-related technologies (artillery shell [[artillery shell range (research)|range]] and [[artillery shell shooting speed (research)|shooting speed]]) are infinite-only; for these, <code>1 - ∞</code> is shown before any levels in them are researched. In either case, once the first infinite level is researched, the card label switches to the one discussed above.

=== Pricing formulas ===

The price of all infinite technologies is generated in a [[Wikipedia:Progression|mathematical progression]]; for the majority of technologies, the progression is [[Wikipedia:Geometric_progression|geometric]], mostly in powers of 2. Two technologies - [[mining productivity (research)|mining productivity]] and [[follower robot count (research)|follower robot count]] - use an [[Wikipedia:Arithmetic_progression|arithmetic progression]] instead.

The table below summarizes for all infinite researches their first infinite level, the cost of the first few infinite levels, the cost formula and the per-level bonus.

We denote by <code>N</code> the current level of the research, by <code>F</code> the final non-infinite level of the research (hence F+1 is the first "infinite" level) and by <code>P[N]</code> the price of the research at level <code>N</code>.

=== Cumulative cost ===

As the price of most infinite technologies (specifically, those based on geometric progressions) increases very steeply, it may be a good idea for players to set realistic target levels for each of the infinite technologies they wish to pursue, and make their factory plans accordingly. To that end, the following properties of cumulative infinite research prices may be useful:

#For infinite technologies whose underlying equation is a powers-of-two geometric series, the cumulative price of the first <code>N - F</code> infinite levels (skipping the first <code>F</code> level, so counting "infinite" levels only) is <code>2 × P[N] - P[F+1]</code>; i.e., twice the price of the final researched level, less the price of the first "infinite" level.
#*As ''N'' increases, this is approximated well by <code>2 × P[N] = P[N+1]</code>, so the cumulative cost of researching to level <code>N</code> is about as much as researching level <code>N+1</code>.
#*If one decides a level <code>M</code> which one considers the "highest feasible" with their current science pack production capacity, expanding said capacity by a factor of <code>X</code> will allow about <code>log[2](X)</code> additional levels to be researched before the next level takes longer to research with the expanded capacity than level <code>M + 1</code> would have taken with the pre-expansion production capacity.
#*For example, if one expands production capacity by a factor of 10, they will be able to research at least <code>floor(log[2](10)) = 3</code> and at most <code>ceiling(log[2](10)) = 4</code> additional levels in a given technology before the exponential increase in price negates the speed benefits of their ×10 capacity expansion.
#The cumulative price of the first <code>N - F</code> levels of infinite technologies whose underlying equation is an arithmetic series is <code>(N - F) × (P[N] + P[F + 1]) ÷ 2</code>; i.e, <code>N - F</code> times the mean of the prices of the first and last "infinite" level. For the [[Follower robot count (research)]], an additional <code>900 × (N-F)</code> need to be added.
#*Expanding production capacity by a factor of <code>X</code>, as above, will in this case allow an additional <code>N × (X - 1)</code> levels to be researched before the benefit of the expansion is wiped out (i.e., research progress speed drops to or below what it was pre-expansion).
#The cumulative price of the first '''''N''''' levels of '''artillery shell shooting speed''', the sole infinite technology whose underlying equation is a powers-of-three geometric series (equation type (2)) is <code>1.5 × P[N] - 0.5 × P[1]</code>; i.e., 1.5 times the price of the final researched level, less half the price of the first level.

Note that these prices reflect '''research units''', which will not be equal to science packs if [[productivity module|productivity modules]] are used in labs. (In that case, the science pack requirement will be lower.)

=== Infinite productivity research limits {{SA}} ===

All recipes have a maximum productivity of 300%. This was [https://factorio.com/blog/post/fff-375 primarily done to prevent infinite resource exploits] involving the [[recycler]]{{SA}} and its 25% return of input items. This cap puts a hard limit on the effectiveness of most infinite productivity researches. You can research past level 30 of these technologies, but it will have no practical effects.

Note that miners are not crafting machines that execute recipes, nor are labs. As such, [[mining productivity (research)]] and [[research productivity (research)]]{{SA}} have no limit.

The [[Railgun shooting speed (research)|railgun turrets shooting speed]] is tied to its [https://forums.factorio.com/viewtopic.php?p=625202#p625202 animation], making the max shooting speed bonus +0.36/s. You can research past level 5, but it will have no practical effect on the [[railgun turret]], however it '''will''' continue to increase the shooting speed of the [[railgun]] past level 5.

[[File:Technology tree.png|thumb|right|280px|The technology tree − Click to enlarge.]]
[[File:tech_bonuses.png|thumb|right|280px|Researched tech bonuses.]]
'''Technologies''' are series of [[research]] projects that provide various enhancements. Some technologies unlock new items or recipes, while others provide bonuses.

Most technologies can be researched in [[lab]]s by consuming [[science pack]]s of various types. For example, the [[Logistics (research)|Logistics]] technology can be unlocked by placing 20 [[automation science pack]]s into labs while the technology is selected for research. Some technologies will automatically unlock after meeting specific conditions, without consumption of any science packs.

== Infinite technologies ==

While most technologies in Factorio are either one-off or have a finite, relatively small number of levels available, a few are "infinite", meaning the player can research as many levels as they can afford. All of them unlock bonuses to existing technologies, never new structures or abilities. The per-level bonuses are constant for a particular infinite technologies and, like finite research bonuses, are additive within a single technology. They are subject to diminishing returns; thus, the per-level and per-science pack contributions from very high levels of infinite technologies will eventually provide only marginal improvements.

All base game infinite technologies levels require [[space science pack]]s, and are also the only technologies that do. As such, they are late-game technologies intended primarily for players who wish to continue playing and expand their factory past the nominal victory condition of launching a rocket.

Infinite technologies are identified in-game by a small <code>∞</code> infinity symbol shown in the top right corner of the research technology's card in the research screen.

Most infinite technologies are continuations of ordinary multi-level technologies; the "infinite" mechanic becomes effective once the player reaches the card initially labeled with <code>N - ∞</code> in the research tree. In the base game, only the two [[artillery]]-related technologies (artillery shell [[artillery shell range (research)|range]] and [[artillery shell shooting speed (research)|shooting speed]]) are infinite-only; for these, <code>1 - ∞</code> is shown before any levels in them are researched. In either case, once the first infinite level is researched, the card label switches to the one discussed above.

=== Pricing formulas ===

The price of all infinite technologies is generated in a [[Wikipedia:Progression|mathematical progression]]; for the majority of technologies, the progression is [[Wikipedia:Geometric_progression|geometric]], mostly in powers of 2. Two technologies - [[mining productivity (research)|mining productivity]] and [[follower robot count (research)|follower robot count]] - use an [[Wikipedia:Arithmetic_progression|arithmetic progression]] instead.

The table below summarizes for all infinite researches their first infinite level, the cost of the first few infinite levels, the cost formula and the per-level bonus.

We denote by <code>N</code> the current level of the research, by <code>F</code> the final non-infinite level of the research (hence F+1 is the first "infinite" level) and by <code>P[N]</code> the price of the research at level <code>N</code>.

=== Cumulative cost ===

As the price of most infinite technologies (specifically, those based on geometric progressions) increases very steeply, it may be a good idea for players to set realistic target levels for each of the infinite technologies they wish to pursue, and make their factory plans accordingly. To that end, the following properties of cumulative infinite research prices may be useful:

#For infinite technologies whose underlying equation is a powers-of-two geometric series, the cumulative price of the first <code>N - F</code> infinite levels (skipping the first <code>F</code> level, so counting "infinite" levels only) is <code>2 × P[N] - P[F+1]</code>; i.e., twice the price of the final researched level, less the price of the first "infinite" level.
#*As ''N'' increases, this is approximated well by <code>2 × P[N] = P[N+1]</code>, so the cumulative cost of researching to level <code>N</code> is about as much as researching level <code>N+1</code>.
#*If one decides a level <code>M</code> which one considers the "highest feasible" with their current science pack production capacity, expanding said capacity by a factor of <code>X</code> will allow about <code>log[2](X)</code> additional levels to be researched before the next level takes longer to research with the expanded capacity than level <code>M + 1</code> would have taken with the pre-expansion production capacity.
#*For example, if one expands production capacity by a factor of 10, they will be able to research at least <code>floor(log[2](10)) = 3</code> and at most <code>ceiling(log[2](10)) = 4</code> additional levels in a given technology before the exponential increase in price negates the speed benefits of their ×10 capacity expansion.
#The cumulative price of the first <code>N - F</code> levels of infinite technologies whose underlying equation is an arithmetic series is <code>(N - F) × (P[N] + P[F + 1]) ÷ 2</code>; i.e, <code>N - F</code> times the mean of the prices of the first and last "infinite" level. For the [[Follower robot count (research)]], an additional <code>900 × (N-F)</code> need to be added.
#*Expanding production capacity by a factor of <code>X</code>, as above, will in this case allow an additional <code>N × (X - 1)</code> levels to be researched before the benefit of the expansion is wiped out (i.e., research progress speed drops to or below what it was pre-expansion).
#The cumulative price of the first '''''N''''' levels of '''artillery shell shooting speed''', the sole infinite technology whose underlying equation is a powers-of-three geometric series (equation type (2)) is <code>1.5 × P[N] - 0.5 × P[1]</code>; i.e., 1.5 times the price of the final researched level, less half the price of the first level.

Note that these prices reflect '''research units''', which will not be equal to science packs if [[productivity module|productivity modules]] are used in labs. (In that case, the science pack requirement will be lower.)

=== Infinite productivity research limits {{SA}} ===

All recipes have a maximum productivity of 300%. This was [https://factorio.com/blog/post/fff-375 primarily done to prevent infinite resource exploits] involving the [[recycler]]{{SA}} and its 25% return of input items. This cap puts a hard limit on the effectiveness of most infinite productivity researches. You can research past level 30 of these technologies, but it will have no practical effects.

Note that miners are not crafting machines that execute recipes, nor are labs. As such, [[mining productivity (research)]] and [[research productivity (research)]]{{SA}} have no limit.

The [[Railgun shooting speed (research)|railgun turrets shooting speed]] is tied to its [https://forums.factorio.com/viewtopic.php?p=625202#p625202 animation], making the max shooting speed bonus +0.36/s. You can research past level 5, but it will have no practical effect on the [[railgun turret]], however it '''will''' continue to increase the shooting speed of the [[railgun]] past level 5.

Rocket part

Domisum: Repeat subject

{{Languages}}
{{:Infobox:Rocket part}}

'''Rocket parts''' are items created by a [[rocket silo]]. Once enough rocket parts have been created, a rocket is built which can launch materials into space. Rocket parts are stored within the silo itself, are not accessible to machines or the player and will be lost if the rocket silo is deconstructed.

In the base game, a rocket requires 100 rocket parts, while in [[Space Age]] only 50 are required and the cost of each part is significantly reduced. Space Age also adds the pseudo-infinite [[productivity]] technology [[rocket part productivity (research)]], which effectively makes rocket parts less expensive.

'''Achievements''' are given to the player when certain events happen or criteria is fulfilled. Some achievements are meant to make the player feel invested in the game. Others are meant to guide the player to use different strategies and optional game mechanics. Achievements are available in both the [http://store.steampowered.com/app/427520/ Steam] and standalone versions. There are 88 achievements available: 59 in the base game, and an additional 29 when using [[Space Age]]{{SA}}.

== Disabling achievements ==
[[File:achievement_list.png|thumb|200px|right|Achievement list in-game.]]Achievements can only be unlocked in the default game mode, called ''Freeplay''. Any scenarios, such as the [[tutorial]] or [[scenario system|custom scenarios]] disable achievements. Furthermore, using script or cheat commands in the [[Console#Scripting_and_cheat_commands|console]] disables achievements, however the user will be warned about this the first time they try to run such a command. Within the freeplay game, changing any enemy or pollution settings to anything lower than default disables the following achievements, and will warn the player of this before they start the game:
* There is no spoon
* No time for chitchat
* Raining bullets
* Steam all the way
* Keeping your hands clean
* It stinks and they don't like it
* It stinks and they do like it{{SA}}
* Get off my lawn{{SA}}
* Work around the clock{{SA}}
* Express delivery{{SA}}

Any other changes to map generation or using the [[debug mode]]s does not disable achievements.

A separate instance of achievements will be used when mods are installed and earned achievements will not register with Steam. In multiplayer, achievements can only be earned if the player has spent more than 50% of the time online on the map where the achievement is being awarded.

Re-enabling achievements again can be achieved by editing the binary data of a save. ([https://forums.factorio.com/58077 reference])

Rocket part

{{:Infobox:Rocket part}}

'''Rocket parts''' are items created by a [[rocket silo]]. Once enough rocket parts have been created, a rocket is built which can launch materials into space. They are stored within the silo itself, are not accessible to machines or the player and will be lost if the rocket silo is deconstructed.

In the base game, a rocket requires 100 rocket parts, while in [[Space Age]] only 50 are required and the cost of each part is significantly reduced. Space Age also adds the pseudo-infinite [[productivity]] technology [[rocket part productivity (research)]], which effectively makes rocket parts less expensive.

== History ==

{{history|2.0.24|
* Changed the Rocket part icon to look more like a part of the rocket.
}}

{{history|2.0.7|
* Recipe changed from using rocket control units to [[processing unit]]s.
}}

{{history|0.12.0|

Others are meant to guide the player to use different strategies and optional game mechanics. Achievements are available in both the [http://store.steampowered.com/app/427520/ Steam] and standalone versions. There are 88 achievements available: 59 in the base game, and an additional 29 when using [[Space Age]]{{SA}}.

Achievements

Domisum: phrasing

{{Languages}}
'''Achievements''' are given to the player when certain events happen or criteria is fulfilled. Some achievements are meant to make the player feel invested in the game. Others are meant to guide the player to use different strategies and optional game mechanics. Achievements are available in both the [http://store.steampowered.com/app/427520/ Steam] and standalone versions. There are 88 achievements available: 59 in the base game, and an additional 29 when using [[Space Age]]{{SA}}.

== Disabling achievements ==
[[File:achievement_list.png|thumb|200px|right|Achievement list in-game.]]Achievements can only be unlocked in the default game mode, called ''Freeplay''. Any scenarios, such as the [[tutorial]] or [[scenario system|custom scenarios]] disable achievements. Furthermore, using script or cheat commands in the [[Console#Scripting_and_cheat_commands|console]] disables achievements, however the user will be warned about this the first time they try to run such a command. Within the freeplay game, changing any enemy or pollution settings to anything lower than default disables the following achievements, and will warn the player of this before they start the game:
* There is no spoon
* No time for chitchat
* Raining bullets
* Steam all the way
* Keeping your hands clean
* It stinks and they don't like it
* It stinks and they do like it{{SA}}
* Get off my lawn{{SA}}
* Work around the clock{{SA}}
* Express delivery{{SA}}

Any other changes to map generation or using the [[debug mode]]s does not disable achievements.

A separate instance of achievements will be used when mods are installed and earned achievements will not register with Steam. In multiplayer, achievements can only be earned if the player has spent more than 50% of the time online on the map where the achievement is being awarded.

Re-enabling achievements again can be achieved by editing the binary data of a save. ([https://forums.factorio.com/58077 reference])

Rocket part

Domisum:

{{Languages}}
{{:Infobox:Rocket part}}

'''Rocket parts''' are items created by a [[rocket silo]]. They are stored within the silo itself; once enough rocket parts have been constructed, a rocket is built which can launch materials into space. In vanilla, a rocket requires 100 rocket parts, while in [[Space Age]] it requires only 50. Space Age also adds the pseudo-infinite [[productivity]] tech [[rocket part productivity (research)]], which effectively makes rocket parts less expensive.

== History ==

'''Promethium asteroid chunk''' is a resource gathered by [[asteroid collector|asteroid collectors]] when traveling to the [[Shattered planet]]. It has only one use: making [[promethium science pack]]s.

As asteroid chunks stack size is only 1, [[Transport belt|belts]] can hold more chunks per tile (8) than [[cargo bay]]s.

Technologies

2025-06-30T15:13:07Z

Domisum: Explain split of energy weapons damage tech

{{Languages}}
[[File:Technology tree.png|thumb|right|280px|The technology tree − Click to enlarge.]]
[[File:tech_bonuses.png|thumb|right|280px|Researched tech bonuses.]]
'''Technologies''' are series of [[research]] projects that provide various enhancements. Some technologies unlock new items or recipes, while others provide bonuses.

Most technologies can be researched in [[lab]]s by consuming [[science pack]]s of various types. For example, the [[Logistics (research)|Logistics]] technology can be unlocked by placing 20 [[automation science pack]]s into labs while the technology is selected for research. Some technologies will automatically unlock after meeting specific conditions, without consumption of any science packs.

== Infinite technologies ==

While most technologies in Factorio are either one-off or have a finite, relatively small number of levels available, a few are "infinite", meaning the player can research as many levels as they can afford. All of them unlock bonuses to existing technologies, never new structures or abilities. The per-level bonuses are constant for a particular infinite technologies and, like finite research bonuses, are additive within a single technology. They are subject to diminishing returns; thus, the per-level and per-science pack contributions from very high levels of infinite technologies will eventually provide only marginal improvements.

All base game infinite technologies levels require [[space science pack]]s, and are also the only technologies that do. As such, they are late-game technologies intended primarily for players who wish to continue playing and expand their factory past the nominal victory condition of launching a rocket.

Infinite technologies are identified in-game by a small <code>∞</code> infinity symbol shown in the top right corner of the research technology's card in the research screen.

Most infinite technologies are continuations of ordinary multi-level technologies; the "infinite" mechanic becomes effective once the player reaches the card initially labeled with <code>N - ∞</code> in the research tree. In the base game, only the two [[artillery]]-related technologies (artillery shell [[artillery shell range (research)|range]] and [[artillery shell shooting speed (research)|shooting speed]]) are infinite-only; for these, <code>1 - ∞</code> is shown before any levels in them are researched. In either case, once the first infinite level is researched, the card label switches to the one discussed above.

=== Pricing formulas ===

The price of all infinite technologies is generated in a [[Wikipedia:Progression|mathematical progression]]; for the majority of technologies, the progression is [[Wikipedia:Geometric_progression|geometric]], mostly in powers of 2. Two technologies - [[mining productivity (research)|mining productivity]] and [[follower robot count (research)|follower robot count]] - use an [[Wikipedia:Arithmetic_progression|arithmetic progression]] instead.

The table below summarizes for all infinite researches their first infinite level, the cost of the first few infinite levels, the cost formula and the per-level bonus.

We denote by <code>N</code> the current level of the research, by <code>F</code> the final non-infinite level of the research (hence F+1 is the first "infinite" level) and by <code>P[N]</code> the price of the research at level <code>N</code>.

=== Cumulative cost ===

As the price of most infinite technologies (specifically, those based on geometric progressions) increases very steeply, it may be a good idea for players to set realistic target levels for each of the infinite technologies they wish to pursue, and make their factory plans accordingly. To that end, the following properties of cumulative infinite research prices may be useful:

#For infinite technologies whose underlying equation is a powers-of-two geometric series, the cumulative price of the first <code>N - F</code> infinite levels (skipping the first <code>F</code> level, so counting "infinite" levels only) is <code>2 × P[N] - P[F+1]</code>; i.e., twice the price of the final researched level, less the price of the first "infinite" level.
#*As ''N'' increases, this is approximated well by <code>2 × P[N] = P[N+1]</code>, so the cumulative cost of researching to level <code>N</code> is about as much as researching level <code>N+1</code>.
#*If one decides a level <code>M</code> which one considers the "highest feasible" with their current science pack production capacity, expanding said capacity by a factor of <code>X</code> will allow about <code>log[2](X)</code> additional levels to be researched before the next level takes longer to research with the expanded capacity than level <code>M + 1</code> would have taken with the pre-expansion production capacity.
#*For example, if one expands production capacity by a factor of 10, they will be able to research at least <code>floor(log[2](10)) = 3</code> and at most <code>ceiling(log[2](10)) = 4</code> additional levels in a given technology before the exponential increase in price negates the speed benefits of their ×10 capacity expansion.
#The cumulative price of the first <code>N - F</code> levels of infinite technologies whose underlying equation is an arithmetic series is <code>(N - F) × (P[N] + P[F + 1]) ÷ 2</code>; i.e, <code>N - F</code> times the mean of the prices of the first and last "infinite" level. For the [[Follower robot count (research)]], an additional <code>900 × (N-F)</code> need to be added.
#*Expanding production capacity by a factor of <code>X</code>, as above, will in this case allow an additional <code>N × (X - 1)</code> levels to be researched before the benefit of the expansion is wiped out (i.e., research progress speed drops to or below what it was pre-expansion).
#The cumulative price of the first '''''N''''' levels of '''artillery shell shooting speed''', the sole infinite technology whose underlying equation is a powers-of-three geometric series (equation type (2)) is <code>1.5 × P[N] - 0.5 × P[1]</code>; i.e., 1.5 times the price of the final researched level, less half the price of the first level.

Note that these prices reflect '''research units''', which will not be equal to science packs if [[productivity module|productivity modules]] are used in labs. (In that case, the science pack requirement will be lower.)

=== Infinite productivity research limits {{SA}} ===

All recipes have a maximum productivity of 300%. This was [https://factorio.com/blog/post/fff-375 primarily done to prevent infinite resource exploits] involving the [[recycler]]{{SA}} and its 25% return of input items. This cap puts a hard limit on the effectiveness of most infinite productivity researches. You can research past level 30 of these technologies, but it will have no practical effects.

Note that miners are not crafting machines that execute recipes, nor are labs. As such, [[mining productivity (research)]] and [[research productivity (research)]]{{SA}} have no limit.

The [[Railgun shooting speed (research)|railgun turrets shooting speed]] is tied to its [https://forums.factorio.com/viewtopic.php?p=625202#p625202 animation], making the max shooting speed bonus +0.36/s. You can research past level 5, but it will have no practical effect on the [[railgun turret]], however it '''will''' continue to increase the shooting speed of the [[railgun]] past level 5.

Domisum: Copy over exact wording of bonuses in game for base game infinite researches

{{Languages}}
[[File:Technology tree.png|thumb|right|280px|The technology tree − Click to enlarge.]]
[[File:tech_bonuses.png|thumb|right|280px|Researched tech bonuses.]]
'''Technologies''' are series of [[research]] projects that provide various enhancements. Some technologies unlock new items or recipes, while others provide bonuses.

Most technologies can be researched in [[lab]]s by consuming [[science pack]]s of various types. For example, the [[Logistics (research)|Logistics]] technology can be unlocked by placing 20 [[automation science pack]]s into labs while the technology is selected for research. Some technologies will automatically unlock after meeting specific conditions, without consumption of any science packs.

== Infinite technologies ==

While most technologies in Factorio are either one-off or have a finite, relatively small number of levels available, a few are "infinite", meaning the player can research as many levels as they can afford. All of them unlock bonuses to existing technologies, never new structures or abilities. The per-level bonuses are constant for a particular infinite technologies and, like finite research bonuses, are additive within a single technology. They are subject to diminishing returns; thus, the per-level and per-science pack contributions from very high levels of infinite technologies will eventually provide only marginal improvements.

All base game infinite technologies levels require [[space science pack]]s, and are also the only technologies that do. As such, they are late-game technologies intended primarily for players who wish to continue playing and expand their factory past the nominal victory condition of launching a rocket.

Infinite technologies are identified in-game by a small <code>∞</code> infinity symbol shown in the top right corner of the research technology's card in the research screen.

Most infinite technologies are continuations of ordinary multi-level technologies; the "infinite" mechanic becomes effective once the player reaches the card initially labeled with <code>N - ∞</code> in the research tree. In the base game, only the two [[artillery]]-related technologies (artillery shell [[artillery shell range (research)|range]] and [[artillery shell shooting speed (research)|shooting speed]]) are infinite-only; for these, <code>1 - ∞</code> is shown before any levels in them are researched. In either case, once the first infinite level is researched, the card label switches to the one discussed above.

=== Pricing formulas ===

The price of all infinite technologies is generated in a [[Wikipedia:Progression|mathematical progression]]; for the majority of technologies, the progression is [[Wikipedia:Geometric_progression|geometric]], mostly in powers of 2. Two technologies - [[mining productivity (research)|mining productivity]] and [[follower robot count (research)|follower robot count]] - use an [[Wikipedia:Arithmetic_progression|arithmetic progression]] instead.

The table below summarizes for all infinite researches their first infinite level, the cost of the first few infinite levels, the cost formula and the per-level bonus.

We denote by <code>N</code> the current level of the research, by <code>F</code> the final non-infinite level of the research (hence F+1 is the first "infinite" level) and by <code>P[N]</code> the price of the research at level <code>N</code>.

=== Cumulative cost ===

As the price of most infinite technologies (specifically, those based on geometric progressions) increases very steeply, it may be a good idea for players to set realistic target levels for each of the infinite technologies they wish to pursue, and make their factory plans accordingly. To that end, the following properties of cumulative infinite research prices may be useful:

#For infinite technologies whose underlying equation is a powers-of-two geometric series, the cumulative price of the first <code>N - F</code> infinite levels (skipping the first <code>F</code> level, so counting "infinite" levels only) is <code>2 × P[N] - P[F+1]</code>; i.e., twice the price of the final researched level, less the price of the first "infinite" level.
#*As ''N'' increases, this is approximated well by <code>2 × P[N] = P[N+1]</code>, so the cumulative cost of researching to level <code>N</code> is about as much as researching level <code>N+1</code>.
#*If one decides a level <code>M</code> which one considers the "highest feasible" with their current science pack production capacity, expanding said capacity by a factor of <code>X</code> will allow about <code>log[2](X)</code> additional levels to be researched before the next level takes longer to research with the expanded capacity than level <code>M + 1</code> would have taken with the pre-expansion production capacity.
#*For example, if one expands production capacity by a factor of 10, they will be able to research at least <code>floor(log[2](10)) = 3</code> and at most <code>ceiling(log[2](10)) = 4</code> additional levels in a given technology before the exponential increase in price negates the speed benefits of their ×10 capacity expansion.
#The cumulative price of the first <code>N - F</code> levels of infinite technologies whose underlying equation is an arithmetic series is <code>(N - F) × (P[N] + P[F + 1]) ÷ 2</code>; i.e, <code>N - F</code> times the mean of the prices of the first and last "infinite" level. For the [[Follower robot count (research)]], an additional <code>900 × (N-F)</code> need to be added.
#*Expanding production capacity by a factor of <code>X</code>, as above, will in this case allow an additional <code>N × (X - 1)</code> levels to be researched before the benefit of the expansion is wiped out (i.e., research progress speed drops to or below what it was pre-expansion).
#The cumulative price of the first '''''N''''' levels of '''artillery shell shooting speed''', the sole infinite technology whose underlying equation is a powers-of-three geometric series (equation type (2)) is <code>1.5 × P[N] - 0.5 × P[1]</code>; i.e., 1.5 times the price of the final researched level, less half the price of the first level.

Note that these prices reflect '''research units''', which will not be equal to science packs if [[productivity module|productivity modules]] are used in labs. (In that case, the science pack requirement will be lower.)

=== Infinite productivity research limits {{SA}} ===

All recipes have a maximum productivity of 300%. This was [https://factorio.com/blog/post/fff-375 primarily done to prevent infinite resource exploits] involving the [[recycler]]{{SA}} and its 25% return of input items. This cap puts a hard limit on the effectiveness of most infinite productivity researches. You can research past level 30 of these technologies, but it will have no practical effects.

Note that miners are not crafting machines that execute recipes, nor are labs. As such, [[mining productivity (research)]] and [[research productivity (research)]]{{SA}} have no limit.

The [[Railgun shooting speed (research)|railgun turrets shooting speed]] is tied to its [https://forums.factorio.com/viewtopic.php?p=625202#p625202 animation], making the max shooting speed bonus +0.36/s. You can research past level 5, but it will have no practical effect on the [[railgun turret]], however it '''will''' continue to increase the shooting speed of the [[railgun]] past level 5.

[[File:tech_bonuses.png|thumb|right|280px|Researched tech bonuses.]]
'''Technologies''' are series of [[research]] projects that provide various enhancements. Some technologies unlock new items or recipes, while others provide bonuses.

Most technologies can be researched in [[lab]]s by consuming [[science pack]]s of various types. For example, the [[Logistics (research)|Logistics]] technology can be unlocked by placing 20 [[automation science pack]]s into labs while the technology is selected for research. Some technologies will automatically unlock after meeting specific conditions, without consumption of any science packs.

== Infinite technologies ==

While most technologies in Factorio are either one-off or have a finite, relatively small number of levels available, a few are "infinite", meaning the player can research as many levels as they can afford. All of them unlock bonuses to existing technologies, never new structures or abilities. The per-level bonuses are constant for a particular infinite technologies and, like finite research bonuses, are additive within a single technology. They are subject to diminishing returns; thus, the per-level and per-science pack contributions from very high levels of infinite technologies will eventually provide only marginal improvements.

All base game infinite technologies levels require [[space science pack]]s, and are also the only technologies that do. As such, they are late-game technologies intended primarily for players who wish to continue playing and expand their factory past the nominal victory condition of launching a rocket.

Infinite technologies are identified in-game by a small <code>∞</code> infinity symbol shown in the top right corner of the research technology's card in the research screen.

Most infinite technologies are continuations of ordinary multi-level technologies; the "infinite" mechanic becomes effective once the player reaches the card initially labeled with <code>N - ∞</code> in the research tree. In the base game, only the two [[artillery]]-related technologies (artillery shell [[artillery shell range (research)|range]] and [[artillery shell shooting speed (research)|shooting speed]]) are infinite-only; for these, <code>1 - ∞</code> is shown before any levels in them are researched. In either case, once the first infinite level is researched, the card label switches to the one discussed above.

=== Pricing formulas ===

The price of all infinite technologies is generated in a [[Wikipedia:Progression|mathematical progression]]; for the majority of technologies, the progression is [[Wikipedia:Geometric_progression|geometric]], mostly in powers of 2. Two technologies - [[mining productivity (research)|mining productivity]] and [[follower robot count (research)|follower robot count]] - use an [[Wikipedia:Arithmetic_progression|arithmetic progression]] instead.

The table below summarizes for all infinite researches their first infinite level, the cost of the first few infinite levels, the cost formula and the per-level bonus.

We denote by <code>N</code> the current level of the research, by <code>F</code> the final non-infinite level of the research (hence F+1 is the first "infinite" level) and by <code>P[N]</code> the price of the research at level <code>N</code>.

=== Cumulative cost ===

As the price of most infinite technologies (specifically, those based on geometric progressions) increases very steeply, it may be a good idea for players to set realistic target levels for each of the infinite technologies they wish to pursue, and make their factory plans accordingly. To that end, the following properties of cumulative infinite research prices may be useful:

#For infinite technologies whose underlying equation is a powers-of-two geometric series, the cumulative price of the first <code>N - F</code> infinite levels (skipping the first <code>F</code> level, so counting "infinite" levels only) is <code>2 × P[N] - P[F+1]</code>; i.e., twice the price of the final researched level, less the price of the first "infinite" level.
#*As ''N'' increases, this is approximated well by <code>2 × P[N] = P[N+1]</code>, so the cumulative cost of researching to level <code>N</code> is about as much as researching level <code>N+1</code>.
#*If one decides a level <code>M</code> which one considers the "highest feasible" with their current science pack production capacity, expanding said capacity by a factor of <code>X</code> will allow about <code>log[2](X)</code> additional levels to be researched before the next level takes longer to research with the expanded capacity than level <code>M + 1</code> would have taken with the pre-expansion production capacity.
#*For example, if one expands production capacity by a factor of 10, they will be able to research at least <code>floor(log[2](10)) = 3</code> and at most <code>ceiling(log[2](10)) = 4</code> additional levels in a given technology before the exponential increase in price negates the speed benefits of their ×10 capacity expansion.
#The cumulative price of the first <code>N - F</code> levels of infinite technologies whose underlying equation is an arithmetic series is <code>(N - F) × (P[N] + P[F + 1]) ÷ 2</code>; i.e, <code>N - F</code> times the mean of the prices of the first and last "infinite" level. For the [[Follower robot count (research)]], an additional <code>900 × (N-F)</code> need to be added.
#*Expanding production capacity by a factor of <code>X</code>, as above, will in this case allow an additional <code>N × (X - 1)</code> levels to be researched before the benefit of the expansion is wiped out (i.e., research progress speed drops to or below what it was pre-expansion).
#The cumulative price of the first '''''N''''' levels of '''artillery shell shooting speed''', the sole infinite technology whose underlying equation is a powers-of-three geometric series (equation type (2)) is <code>1.5 × P[N] - 0.5 × P[1]</code>; i.e., 1.5 times the price of the final researched level, less half the price of the first level.

Note that these prices reflect '''research units''', which will not be equal to science packs if [[productivity module|productivity modules]] are used in labs. (In that case, the science pack requirement will be lower.)

=== Infinite productivity research limits {{SA}} ===

All recipes have a maximum productivity of 300%. This was [https://factorio.com/blog/post/fff-375 primarily done to prevent infinite resource exploits] involving the [[recycler]]{{SA}} and its 25% return of input items. This cap puts a hard limit on the effectiveness of most infinite productivity researches. You can research past level 30 of these technologies, but it will have no practical effects.

Note that miners are not crafting machines that execute recipes, nor are labs. As such, [[mining productivity (research)]] and [[research productivity (research)]]{{SA}} have no limit.

The [[Railgun shooting speed (research)|railgun turrets shooting speed]] is tied to its [https://forums.factorio.com/viewtopic.php?p=625202#p625202 animation], making the max shooting speed bonus +0.36/s. You can research past level 5, but it will have no practical effect on the [[railgun turret]], however it '''will''' continue to increase the shooting speed of the [[railgun]] past level 5.

Domisum: Copy over exact wording of bonuses in game for SA infinite researches

{{Languages}}
[[File:Technology tree.png|thumb|right|280px|The technology tree − Click to enlarge.]]
[[File:tech_bonuses.png|thumb|right|280px|Researched tech bonuses.]]
'''Technologies''' are series of [[research]] projects that provide various enhancements. Some technologies unlock new items or recipes, while others provide bonuses.

Most technologies can be researched in [[lab]]s by consuming [[science pack]]s of various types. For example, the [[Logistics (research)|Logistics]] technology can be unlocked by placing 20 [[automation science pack]]s into labs while the technology is selected for research. Some technologies will automatically unlock after meeting specific conditions, without consumption of any science packs.

== Infinite technologies ==

While most technologies in Factorio are either one-off or have a finite, relatively small number of levels available, a few are "infinite", meaning the player can research as many levels as they can afford. All of them unlock bonuses to existing technologies, never new structures or abilities. The per-level bonuses are constant for a particular infinite technologies and, like finite research bonuses, are additive within a single technology. They are subject to diminishing returns; thus, the per-level and per-science pack contributions from very high levels of infinite technologies will eventually provide only marginal improvements.

All base game infinite technologies levels require [[space science pack]]s, and are also the only technologies that do. As such, they are late-game technologies intended primarily for players who wish to continue playing and expand their factory past the nominal victory condition of launching a rocket.

Infinite technologies are identified in-game by a small <code>∞</code> infinity symbol shown in the top right corner of the research technology's card in the research screen.

Most infinite technologies are continuations of ordinary multi-level technologies; the "infinite" mechanic becomes effective once the player reaches the card initially labeled with <code>N - ∞</code> in the research tree. In the base game, only the two [[artillery]]-related technologies (artillery shell [[artillery shell range (research)|range]] and [[artillery shell shooting speed (research)|shooting speed]]) are infinite-only; for these, <code>1 - ∞</code> is shown before any levels in them are researched. In either case, once the first infinite level is researched, the card label switches to the one discussed above.

=== Pricing formulas ===

The price of all infinite technologies is generated in a [[Wikipedia:Progression|mathematical progression]]; for the majority of technologies, the progression is [[Wikipedia:Geometric_progression|geometric]], mostly in powers of 2. Two technologies - [[mining productivity (research)|mining productivity]] and [[follower robot count (research)|follower robot count]] - use an [[Wikipedia:Arithmetic_progression|arithmetic progression]] instead.

The table below summarizes for all infinite researches their first infinite level, the cost of the first few infinite levels, the cost formula and the per-level bonus.

We denote by <code>N</code> the current level of the research, by <code>F</code> the final non-infinite level of the research (hence F+1 is the first "infinite" level) and by <code>P[N]</code> the price of the research at level <code>N</code>.

=== Cumulative cost ===

As the price of most infinite technologies (specifically, those based on geometric progressions) increases very steeply, it may be a good idea for players to set realistic target levels for each of the infinite technologies they wish to pursue, and make their factory plans accordingly. To that end, the following properties of cumulative infinite research prices may be useful:

#For infinite technologies whose underlying equation is a powers-of-two geometric series, the cumulative price of the first <code>N - F</code> infinite levels (skipping the first <code>F</code> level, so counting "infinite" levels only) is <code>2 × P[N] - P[F+1]</code>; i.e., twice the price of the final researched level, less the price of the first "infinite" level.
#*As ''N'' increases, this is approximated well by <code>2 × P[N] = P[N+1]</code>, so the cumulative cost of researching to level <code>N</code> is about as much as researching level <code>N+1</code>.
#*If one decides a level <code>M</code> which one considers the "highest feasible" with their current science pack production capacity, expanding said capacity by a factor of <code>X</code> will allow about <code>log[2](X)</code> additional levels to be researched before the next level takes longer to research with the expanded capacity than level <code>M + 1</code> would have taken with the pre-expansion production capacity.
#*For example, if one expands production capacity by a factor of 10, they will be able to research at least <code>floor(log[2](10)) = 3</code> and at most <code>ceiling(log[2](10)) = 4</code> additional levels in a given technology before the exponential increase in price negates the speed benefits of their ×10 capacity expansion.
#The cumulative price of the first <code>N - F</code> levels of infinite technologies whose underlying equation is an arithmetic series is <code>(N - F) × (P[N] + P[F + 1]) ÷ 2</code>; i.e, <code>N - F</code> times the mean of the prices of the first and last "infinite" level. For the [[Follower robot count (research)]], an additional <code>900 × (N-F)</code> need to be added.
#*Expanding production capacity by a factor of <code>X</code>, as above, will in this case allow an additional <code>N × (X - 1)</code> levels to be researched before the benefit of the expansion is wiped out (i.e., research progress speed drops to or below what it was pre-expansion).
#The cumulative price of the first '''''N''''' levels of '''artillery shell shooting speed''', the sole infinite technology whose underlying equation is a powers-of-three geometric series (equation type (2)) is <code>1.5 × P[N] - 0.5 × P[1]</code>; i.e., 1.5 times the price of the final researched level, less half the price of the first level.

Note that these prices reflect '''research units''', which will not be equal to science packs if [[productivity module|productivity modules]] are used in labs. (In that case, the science pack requirement will be lower.)

=== Infinite productivity research limits {{SA}} ===

All recipes have a maximum productivity of 300%. This was [https://factorio.com/blog/post/fff-375 primarily done to prevent infinite resource exploits] involving the [[recycler]]{{SA}} and its 25% return of input items. This cap puts a hard limit on the effectiveness of most infinite productivity researches. You can research past level 30 of these technologies, but it will have no practical effects.

Note that miners are not crafting machines that execute recipes, nor are labs. As such, [[mining productivity (research)]] and [[research productivity (research)]]{{SA}} have no limit.

The [[Railgun shooting speed (research)|railgun turrets shooting speed]] is tied to its [https://forums.factorio.com/viewtopic.php?p=625202#p625202 animation], making the max shooting speed bonus +0.36/s. You can research past level 5, but it will have no practical effect on the [[railgun turret]], however it '''will''' continue to increase the shooting speed of the [[railgun]] past level 5.

[[File:Technology tree.png|thumb|right|280px|The technology tree − Click to enlarge.]]
[[File:tech_bonuses.png|thumb|right|280px|Researched tech bonuses.]]
'''Technologies''' are series of [[research]] projects that provide various enhancements. Some technologies unlock new items or recipes, while others provide bonuses.

Most technologies can be researched in [[lab]]s by consuming [[science pack]]s of various types. For example, the [[Logistics (research)|Logistics]] technology can be unlocked by placing 20 [[automation science pack]]s into labs while the technology is selected for research. Some technologies will automatically unlock after meeting specific conditions, without consumption of any science packs.

== Infinite technologies ==

While most technologies in Factorio are either one-off or have a finite, relatively small number of levels available, a few are "infinite", meaning the player can research as many levels as they can afford. All of them unlock bonuses to existing technologies, never new structures or abilities. The per-level bonuses are constant for a particular infinite technologies and, like finite research bonuses, are additive within a single technology. They are subject to diminishing returns; thus, the per-level and per-science pack contributions from very high levels of infinite technologies will eventually provide only marginal improvements.

All base game infinite technologies levels require [[space science pack]]s, and are also the only technologies that do. As such, they are late-game technologies intended primarily for players who wish to continue playing and expand their factory past the nominal victory condition of launching a rocket.

Infinite technologies are identified in-game by a small <code>∞</code> infinity symbol shown in the top right corner of the research technology's card in the research screen.

Most infinite technologies are continuations of ordinary multi-level technologies; the "infinite" mechanic becomes effective once the player reaches the card initially labeled with <code>N - ∞</code> in the research tree. In the base game, only the two [[artillery]]-related technologies (artillery shell [[artillery shell range (research)|range]] and [[artillery shell shooting speed (research)|shooting speed]]) are infinite-only; for these, <code>1 - ∞</code> is shown before any levels in them are researched. In either case, once the first infinite level is researched, the card label switches to the one discussed above.

=== Pricing formulas ===

The price of all infinite technologies is generated in a [[Wikipedia:Progression|mathematical progression]]; for the majority of technologies, the progression is [[Wikipedia:Geometric_progression|geometric]], mostly in powers of 2. Two technologies - [[mining productivity (research)|mining productivity]] and [[follower robot count (research)|follower robot count]] - use an [[Wikipedia:Arithmetic_progression|arithmetic progression]] instead.

The table below summarizes for all infinite researches their first infinite level, the cost of the first few infinite levels, the cost formula and the per-level bonus.

We denote by <code>N</code> the current level of the research, by <code>F</code> the final non-infinite level of the research (hence F+1 is the first "infinite" level) and by <code>P[N]</code> the price of the research at level <code>N</code>.

=== Cumulative cost ===

As the price of most infinite technologies (specifically, those based on geometric progressions) increases very steeply, it may be a good idea for players to set realistic target levels for each of the infinite technologies they wish to pursue, and make their factory plans accordingly. To that end, the following properties of cumulative infinite research prices may be useful:

#For infinite technologies whose underlying equation is a powers-of-two geometric series, the cumulative price of the first <code>N - F</code> infinite levels (skipping the first <code>F</code> level, so counting "infinite" levels only) is <code>2 × P[N] - P[F+1]</code>; i.e., twice the price of the final researched level, less the price of the first "infinite" level.
#*As ''N'' increases, this is approximated well by <code>2 × P[N] = P[N+1]</code>, so the cumulative cost of researching to level <code>N</code> is about as much as researching level <code>N+1</code>.
#*If one decides a level <code>M</code> which one considers the "highest feasible" with their current science pack production capacity, expanding said capacity by a factor of <code>X</code> will allow about <code>log[2](X)</code> additional levels to be researched before the next level takes longer to research with the expanded capacity than level <code>M + 1</code> would have taken with the pre-expansion production capacity.
#*For example, if one expands production capacity by a factor of 10, they will be able to research at least <code>floor(log[2](10)) = 3</code> and at most <code>ceiling(log[2](10)) = 4</code> additional levels in a given technology before the exponential increase in price negates the speed benefits of their ×10 capacity expansion.
#The cumulative price of the first <code>N - F</code> levels of infinite technologies whose underlying equation is an arithmetic series is <code>(N - F) × (P[N] + P[F + 1]) ÷ 2</code>; i.e, <code>N - F</code> times the mean of the prices of the first and last "infinite" level. For the [[Follower robot count (research)]], an additional <code>900 × (N-F)</code> need to be added.
#*Expanding production capacity by a factor of <code>X</code>, as above, will in this case allow an additional <code>N × (X - 1)</code> levels to be researched before the benefit of the expansion is wiped out (i.e., research progress speed drops to or below what it was pre-expansion).
#The cumulative price of the first '''''N''''' levels of '''artillery shell shooting speed''', the sole infinite technology whose underlying equation is a powers-of-three geometric series (equation type (2)) is <code>1.5 × P[N] - 0.5 × P[1]</code>; i.e., 1.5 times the price of the final researched level, less half the price of the first level.

Note that these prices reflect '''research units''', which will not be equal to science packs if [[productivity module|productivity modules]] are used in labs. (In that case, the science pack requirement will be lower.)

=== Infinite productivity research limits {{SA}} ===

All recipes have a maximum productivity of 300%. This was [https://factorio.com/blog/post/fff-375 primarily done to prevent infinite resource exploits] involving the [[recycler]]{{SA}} and its 25% return of input items. This cap puts a hard limit on the effectiveness of most infinite productivity researches. You can research past level 30 of these technologies, but it will have no practical effects.

Note that miners are not crafting machines that execute recipes, nor are labs. As such, [[mining productivity (research)]] and [[research productivity (research)]]{{SA}} have no limit.

The [[Railgun shooting speed (research)|railgun turrets shooting speed]] is tied to its [https://forums.factorio.com/viewtopic.php?p=625202#p625202 animation], making the max shooting speed bonus +0.36/s. You can research past level 5, but it will have no practical effect on the [[railgun turret]], however it '''will''' continue to increase the shooting speed of the [[railgun]] past level 5.

[[File:Technology tree.png|thumb|right|280px|The technology tree − Click to enlarge.]]
[[File:tech_bonuses.png|thumb|right|280px|Researched tech bonuses.]]
'''Technologies''' are series of [[research]] projects that provide various enhancements. Some technologies unlock new items or recipes, while others provide bonuses.

Most technologies need a certain amount of [[science pack]]s per science pack type to be researched in [[lab]]s, for example the [[Logistics (research)|Logistics]] technology requires 20 [[automation science pack]]s to be placed in labs while the technology is selected for research. While some technologies will also automatically unlock after meeting specific conditions.

== Infinite technologies ==

While most technologies in Factorio are either one-off or have a finite, relatively small number of levels available, a few are "infinite", meaning the player can research as many levels as they can afford. All of them unlock bonuses to existing technologies, never new structures or abilities. The per-level bonuses are constant for a particular infinite technologies and, like finite research bonuses, are additive within a single technology. They are subject to diminishing returns; thus, the per-level and per-science pack contributions from very high levels of infinite technologies will eventually provide only marginal improvements.

All base game infinite technologies levels require [[space science pack]]s, and are also the only technologies that do. As such, they are late-game technologies intended primarily for players who wish to continue playing and expand their factory past the nominal victory condition of launching a rocket.

Infinite technologies are identified in-game by a small <code>∞</code> infinity symbol shown in the top right corner of the research technology's card in the research screen.

Most infinite technologies are continuations of ordinary multi-level technologies; the "infinite" mechanic becomes effective once the player reaches the card initially labeled with <code>N - ∞</code> in the research tree. In the base game, only the two [[artillery]]-related technologies (artillery shell [[artillery shell range (research)|range]] and [[artillery shell shooting speed (research)|shooting speed]]) are infinite-only; for these, <code>1 - ∞</code> is shown before any levels in them are researched. In either case, once the first infinite level is researched, the card label switches to the one discussed above.

=== Pricing formulas ===

The price of all infinite technologies is generated in a [[Wikipedia:Progression|mathematical progression]]; for the majority of technologies, the progression is [[Wikipedia:Geometric_progression|geometric]], mostly in powers of 2. Two technologies - [[mining productivity (research)|mining productivity]] and [[follower robot count (research)|follower robot count]] - use an [[Wikipedia:Arithmetic_progression|arithmetic progression]] instead.

The table below summarizes for all infinite researches their first infinite level, the cost of the first few infinite levels, the cost formula and the per-level bonus.

We denote by <code>N</code> the current level of the research, by <code>F</code> the final non-infinite level of the research (hence F+1 is the first "infinite" level) and by <code>P[N]</code> the price of the research at level <code>N</code>.

=== Cumulative cost ===

As the price of most infinite technologies (specifically, those based on geometric progressions) increases very steeply, it may be a good idea for players to set realistic target levels for each of the infinite technologies they wish to pursue, and make their factory plans accordingly. To that end, the following properties of cumulative infinite research prices may be useful:

#For infinite technologies whose underlying equation is a powers-of-two geometric series, the cumulative price of the first <code>N - F</code> infinite levels (skipping the first <code>F</code> level, so counting "infinite" levels only) is <code>2 × P[N] - P[F+1]</code>; i.e., twice the price of the final researched level, less the price of the first "infinite" level.
#*As ''N'' increases, this is approximated well by <code>2 × P[N] = P[N+1]</code>, so the cumulative cost of researching to level <code>N</code> is about as much as researching level <code>N+1</code>.
#*If one decides a level <code>M</code> which one considers the "highest feasible" with their current science pack production capacity, expanding said capacity by a factor of <code>X</code> will allow about <code>log[2](X)</code> additional levels to be researched before the next level takes longer to research with the expanded capacity than level <code>M + 1</code> would have taken with the pre-expansion production capacity.
#*For example, if one expands production capacity by a factor of 10, they will be able to research at least <code>floor(log[2](10)) = 3</code> and at most <code>ceiling(log[2](10)) = 4</code> additional levels in a given technology before the exponential increase in price negates the speed benefits of their ×10 capacity expansion.
#The cumulative price of the first <code>N - F</code> levels of infinite technologies whose underlying equation is an arithmetic series is <code>(N - F) × (P[N] + P[F + 1]) ÷ 2</code>; i.e, <code>N - F</code> times the mean of the prices of the first and last "infinite" level. For the [[Follower robot count (research)]], an additional <code>900 × (N-F)</code> need to be added.
#*Expanding production capacity by a factor of <code>X</code>, as above, will in this case allow an additional <code>N × (X - 1)</code> levels to be researched before the benefit of the expansion is wiped out (i.e., research progress speed drops to or below what it was pre-expansion).
#The cumulative price of the first '''''N''''' levels of '''artillery shell shooting speed''', the sole infinite technology whose underlying equation is a powers-of-three geometric series (equation type (2)) is <code>1.5 × P[N] - 0.5 × P[1]</code>; i.e., 1.5 times the price of the final researched level, less half the price of the first level.

Note that these prices reflect '''research units''', which will not be equal to science packs if [[productivity module|productivity modules]] are used in labs. (In that case, the science pack requirement will be lower.)

=== Infinite productivity research limits {{SA}} ===

All recipes have a maximum productivity of 300%. This was [https://factorio.com/blog/post/fff-375 primarily done to prevent infinite resource exploits] involving the [[recycler]]{{SA}} and its 25% return of input items. This cap puts a hard limit on the effectiveness of most infinite productivity researches. You can research past level 30 of these technologies, but it will have no practical effects.

Note that miners are not crafting machines that execute recipes, nor are labs. As such, [[mining productivity (research)]] and [[research productivity (research)]]{{SA}} have no limit.

The [[Railgun shooting speed (research)|railgun turrets shooting speed]] is tied to its [https://forums.factorio.com/viewtopic.php?p=625202#p625202 animation], making the max shooting speed bonus +0.36/s. You can research past level 5, but it will have no practical effect on the [[railgun turret]], however it '''will''' continue to increase the shooting speed of the [[railgun]] past level 5.

Domisum: Add Space Age icon to technologies that only exist in the expansion

[[File:Technology tree.png|thumb|right|280px|The technology tree − Click to enlarge.]]
[[File:tech_bonuses.png|thumb|right|280px|Researched tech bonuses.]]
'''Technologies''' are series of [[research]] projects that provide various enhancements. Some technologies unlock new items or recipes, while others provide bonuses.

Most technologies need a certain amount of [[science pack]]s per science pack type to be researched in [[lab]]s, for example the [[Logistics (research)|Logistics]] technology requires 20 [[automation science pack]]s to be placed in labs while the technology is selected for research. While some technologies will also automatically unlock after meeting specific conditions.

== Infinite technologies ==

While most technologies in Factorio are either one-off or have a finite, relatively small number of levels available, a few are "infinite", meaning the player can research as many levels as they can afford. All of them unlock bonuses to existing technologies, never new structures or abilities. The per-level bonuses are constant for a particular infinite technologies and, like finite research bonuses, are additive within a single technology. They are subject to diminishing returns; thus, the per-level and per-science pack contributions from very high levels of infinite technologies will eventually provide only marginal improvements.

All base game infinite technologies levels require [[space science pack]]s, and are also the only technologies that do. As such, they are late-game technologies intended primarily for players who wish to continue playing and expand their factory past the nominal victory condition of launching a rocket.

Infinite technologies are identified in-game by a small <code>∞</code> infinity symbol shown in the top right corner of the research technology's card in the research screen.

Most infinite technologies are continuations of ordinary multi-level technologies; the "infinite" mechanic becomes effective once the player reaches the card initially labeled with <code>N - ∞</code> in the research tree. In the base game, only the two [[artillery]]-related technologies (artillery shell [[artillery shell range (research)|range]] and [[artillery shell shooting speed (research)|shooting speed]]) are infinite-only; for these, <code>1 - ∞</code> is shown before any levels in them are researched. In either case, once the first infinite level is researched, the card label switches to the one discussed above.

=== Pricing formulas ===

The price of all infinite technologies is generated in a [[Wikipedia:Progression|mathematical progression]]; for the majority of technologies, the progression is [[Wikipedia:Geometric_progression|geometric]], mostly in powers of 2. Two technologies - [[mining productivity (research)|mining productivity]] and [[follower robot count (research)|follower robot count]] - use an [[Wikipedia:Arithmetic_progression|arithmetic progression]] instead.

The table below summarizes for all infinite researches their first infinite level, the cost of the first few infinite levels, the cost formula and the per-level bonus.

We denote by <code>N</code> the current level of the research, by <code>F</code> the final non-infinite level of the research (hence F+1 is the first "infinite" level) and by <code>P[N]</code> the price of the research at level <code>N</code>.

=== Cumulative cost ===

As the price of most infinite technologies (specifically, those based on geometric progressions) increases very steeply, it may be a good idea for players to set realistic target levels for each of the infinite technologies they wish to pursue, and make their factory plans accordingly. To that end, the following properties of cumulative infinite research prices may be useful:

#For infinite technologies whose underlying equation is a powers-of-two geometric series, the cumulative price of the first <code>N - F</code> infinite levels (skipping the first <code>F</code> level, so counting "infinite" levels only) is <code>2 × P[N] - P[F+1]</code>; i.e., twice the price of the final researched level, less the price of the first "infinite" level.
#*As ''N'' increases, this is approximated well by <code>2 × P[N] = P[N+1]</code>, so the cumulative cost of researching to level <code>N</code> is about as much as researching level <code>N+1</code>.
#*If one decides a level <code>M</code> which one considers the "highest feasible" with their current science pack production capacity, expanding said capacity by a factor of <code>X</code> will allow about <code>log[2](X)</code> additional levels to be researched before the next level takes longer to research with the expanded capacity than level <code>M + 1</code> would have taken with the pre-expansion production capacity.
#*For example, if one expands production capacity by a factor of 10, they will be able to research at least <code>floor(log[2](10)) = 3</code> and at most <code>ceiling(log[2](10)) = 4</code> additional levels in a given technology before the exponential increase in price negates the speed benefits of their ×10 capacity expansion.
#The cumulative price of the first <code>N - F</code> levels of infinite technologies whose underlying equation is an arithmetic series is <code>(N - F) × (P[N] + P[F + 1]) ÷ 2</code>; i.e, <code>N - F</code> times the mean of the prices of the first and last "infinite" level. For the [[Follower robot count (research)]], an additional <code>900 × (N-F)</code> need to be added.
#*Expanding production capacity by a factor of <code>X</code>, as above, will in this case allow an additional <code>N × (X - 1)</code> levels to be researched before the benefit of the expansion is wiped out (i.e., research progress speed drops to or below what it was pre-expansion).
#The cumulative price of the first '''''N''''' levels of '''artillery shell shooting speed''', the sole infinite technology whose underlying equation is a powers-of-three geometric series (equation type (2)) is <code>1.5 × P[N] - 0.5 × P[1]</code>; i.e., 1.5 times the price of the final researched level, less half the price of the first level.

Note that these prices reflect '''research units''', which will not be equal to science packs if [[productivity module|productivity modules]] are used in labs. (In that case, the science pack requirement will be lower.)

=== Infinite productivity research limits {{SA}} ===

All recipes have a maximum productivity of 300%. This was [https://factorio.com/blog/post/fff-375 primarily done to prevent infinite resource exploits] involving the [[recycler]]{{SA}} and its 25% return of input items. This cap puts a hard limit on the effectiveness of most infinite productivity researches. You can research past level 30 of these technologies, but it will have no practical effects.

Note that miners are not crafting machines that execute recipes, nor are labs. As such, [[mining productivity (research)]] and [[research productivity (research)]]{{SA}} have no limit.

The [[Railgun shooting speed (research)|railgun turrets shooting speed]] is tied to its [https://forums.factorio.com/viewtopic.php?p=625202#p625202 animation], making the max shooting speed bonus +0.36/s. You can research past level 5, but it will have no practical effect on the [[railgun turret]], however it '''will''' continue to increase the shooting speed of the [[railgun]] past level 5.

[[File:tech_bonuses.png|thumb|right|280px|Researched tech bonuses.]]
'''Technologies''' are series of [[research]] projects that provide various enhancements. Some technologies unlock new items or recipes, while others provide bonuses.

Most technologies need a certain amount of [[science pack]]s per science pack type to be researched in [[lab]]s, for example the [[Logistics (research)|Logistics]] technology requires 20 [[automation science pack]]s to be placed in labs while the technology is selected for research. While some technologies will also automatically unlock after meeting specific conditions.

== Infinite technologies ==

While most technologies in Factorio are either one-off or have a finite, relatively small number of levels available, a few are "infinite", meaning the player can research as many levels as they can afford. All of them unlock bonuses to existing technologies, never new structures or abilities. The per-level bonuses are constant for a particular infinite technologies and, like finite research bonuses, are additive within a single technology. They are subject to diminishing returns; thus, the per-level and per-science pack contributions from very high levels of infinite technologies will eventually provide only marginal improvements.

All base game infinite technologies levels require [[space science pack]]s, and are also the only technologies that do. As such, they are late-game technologies intended primarily for players who wish to continue playing and expand their factory past the nominal victory condition of launching a rocket.

Infinite technologies are identified in-game by a small <code>∞</code> infinity symbol shown in the top right corner of the research technology's card in the research screen.

Most infinite technologies are continuations of ordinary multi-level technologies; the "infinite" mechanic becomes effective once the player reaches the card initially labeled with <code>N - ∞</code> in the research tree. In the base game, only the two [[artillery]]-related technologies (artillery shell [[artillery shell range (research)|range]] and [[artillery shell shooting speed (research)|shooting speed]]) are infinite-only; for these, <code>1 - ∞</code> is shown before any levels in them are researched. In either case, once the first infinite level is researched, the card label switches to the one discussed above.

=== Pricing formulas ===

The price of all infinite technologies is generated in a [[Wikipedia:Progression|mathematical progression]]; for the majority of technologies, the progression is [[Wikipedia:Geometric_progression|geometric]], mostly in powers of 2. Two technologies - [[mining productivity (research)|mining productivity]] and [[follower robot count (research)|follower robot count]] - use an [[Wikipedia:Arithmetic_progression|arithmetic progression]] instead.

The table below summarizes for all infinite researches their first infinite level, the cost of the first few infinite levels, the cost formula and the per-level bonus.

We denote by <code>N</code> the current level of the research, by <code>F</code> the final non-infinite level of the research (hence F+1 is the first "infinite" level) and by <code>P[N]</code> the price of the research at level <code>N</code>.

=== Cumulative cost ===

As the price of most infinite technologies (specifically, those based on geometric progressions) increases very steeply, it may be a good idea for players to set realistic target levels for each of the infinite technologies they wish to pursue, and make their factory plans accordingly. To that end, the following properties of cumulative infinite research prices may be useful:

#For infinite technologies whose underlying equation is a powers-of-two geometric series, the cumulative price of the first <code>N - F</code> infinite levels (skipping the first <code>F</code> level, so counting "infinite" levels only) is <code>2 × P[N] - P[F+1]</code>; i.e., twice the price of the final researched level, less the price of the first "infinite" level.
#*As ''N'' increases, this is approximated well by <code>2 × P[N] = P[N+1]</code>, so the cumulative cost of researching to level <code>N</code> is about as much as researching level <code>N+1</code>.
#*If one decides a level <code>M</code> which one considers the "highest feasible" with their current science pack production capacity, expanding said capacity by a factor of <code>X</code> will allow about <code>log[2](X)</code> additional levels to be researched before the next level takes longer to research with the expanded capacity than level <code>M + 1</code> would have taken with the pre-expansion production capacity.
#*For example, if one expands production capacity by a factor of 10, they will be able to research at least <code>floor(log[2](10)) = 3</code> and at most <code>ceiling(log[2](10)) = 4</code> additional levels in a given technology before the exponential increase in price negates the speed benefits of their ×10 capacity expansion.
#The cumulative price of the first <code>N - F</code> levels of infinite technologies whose underlying equation is an arithmetic series is <code>(N - F) × (P[N] + P[F + 1]) ÷ 2</code>; i.e, <code>N - F</code> times the mean of the prices of the first and last "infinite" level. For the [[Follower robot count (research)]], an additional <code>900 × (N-F)</code> need to be added.
#*Expanding production capacity by a factor of <code>X</code>, as above, will in this case allow an additional <code>N × (X - 1)</code> levels to be researched before the benefit of the expansion is wiped out (i.e., research progress speed drops to or below what it was pre-expansion).
#The cumulative price of the first '''''N''''' levels of '''artillery shell shooting speed''', the sole infinite technology whose underlying equation is a powers-of-three geometric series (equation type (2)) is <code>1.5 × P[N] - 0.5 × P[1]</code>; i.e., 1.5 times the price of the final researched level, less half the price of the first level.

Note that these prices reflect '''research units''', which will not be equal to science packs if [[productivity module|productivity modules]] are used in labs. (In that case, the science pack requirement will be lower.)

=== Infinite productivity research limits {{SA}} ===

All recipes have a maximum productivity of 300%. This was [https://factorio.com/blog/post/fff-375 primarily done to prevent infinite resource exploits] involving the [[recycler]]{{SA}} and its 25% return of input items. This cap puts a hard limit on the effectiveness of most infinite productivity researches. You can research past level 30 of these technologies, but it will have no practical effects.

Note that miners are not crafting machines that execute recipes, nor are labs. As such, [[mining productivity (research)]] and [[research productivity (research)]]{{SA}} have no limit.

The [[Railgun shooting speed (research)|railgun turrets shooting speed]] is tied to its [https://forums.factorio.com/viewtopic.php?p=625202#p625202 animation], making the max shooting speed bonus +0.36/s. You can research past level 5, but it will have no practical effect on the [[railgun turret]], however it '''will''' continue to increase the shooting speed of the [[railgun]] past level 5.

[[File:Technology tree.png|thumb|right|280px|The technology tree − Click to enlarge.]]
[[File:tech_bonuses.png|thumb|right|280px|Researched tech bonuses.]]
'''Technologies''' are series of [[research]] projects that provide various enhancements. Some technologies unlock new items or recipes, while others provide bonuses.

Most technologies need a certain amount of [[science pack]]s per science pack type to be researched in [[lab]]s, for example the [[Logistics (research)|Logistics]] technology requires 20 [[automation science pack]]s to be placed in labs while the technology is selected for research. While some technologies will also automatically unlock after meeting specific conditions.

== Infinite technologies ==

While most technologies in Factorio are either one-off or have a finite, relatively small number of levels available, a few are "infinite", meaning the player can research as many levels as they can afford. All of them unlock bonuses to existing technologies, never new structures or abilities. The per-level bonuses are constant for a particular infinite technologies and, like finite research bonuses, are additive within a single technology. They are subject to diminishing returns; thus, the per-level and per-science pack contributions from very high levels of infinite technologies will eventually provide only marginal improvements.

All base game infinite technologies levels require [[space science pack]]s, and are also the only technologies that do. As such, they are late-game technologies intended primarily for players who wish to continue playing and expand their factory past the nominal victory condition of launching a rocket.

Infinite technologies are identified in-game by a small <code>∞</code> infinity symbol shown in the top right corner of the research technology's card in the research screen.

Most infinite technologies are continuations of ordinary multi-level technologies; the "infinite" mechanic becomes effective once the player reaches the card initially labeled with <code>N - ∞</code> in the research tree. In the base game, only the two [[artillery]]-related technologies (artillery shell [[artillery shell range (research)|range]] and [[artillery shell shooting speed (research)|shooting speed]]) are infinite-only; for these, <code>1 - ∞</code> is shown before any levels in them are researched. In either case, once the first infinite level is researched, the card label switches to the one discussed above.

=== Pricing formulas ===

The price of all infinite technologies is generated in a [[Wikipedia:Progression|mathematical progression]]; for the majority of technologies, the progression is [[Wikipedia:Geometric_progression|geometric]], mostly in powers of 2. Two technologies - [[mining productivity (research)|mining productivity]] and [[follower robot count (research)|follower robot count]] - use an [[Wikipedia:Arithmetic_progression|arithmetic progression]] instead.

The table below summarizes for all infinite researches their first infinite level, the cost of the first few infinite levels, the cost formula and the per-level bonus.

We denote by <code>N</code> the current level of the research, by <code>F</code> the final non-infinite level of the research (hence F+1 is the first "infinite" level) and by <code>P[N]</code> the price of the research at level <code>N</code>.

=== Cumulative cost ===

As the price of most infinite technologies (specifically, those based on geometric progressions) increases very steeply, it may be a good idea for players to set realistic target levels for each of the infinite technologies they wish to pursue, and make their factory plans accordingly. To that end, the following properties of cumulative infinite research prices may be useful:

#For infinite technologies whose underlying equation is a powers-of-two geometric series, the cumulative price of the first <code>N - F</code> infinite levels (skipping the first <code>F</code> level, so counting "infinite" levels only) is <code>2 × P[N] - P[F+1]</code>; i.e., twice the price of the final researched level, less the price of the first "infinite" level.
#*As ''N'' increases, this is approximated well by <code>2 × P[N] = P[N+1]</code>, so the cumulative cost of researching to level <code>N</code> is about as much as researching level <code>N+1</code>.
#*If one decides a level <code>M</code> which one considers the "highest feasible" with their current science pack production capacity, expanding said capacity by a factor of <code>X</code> will allow about <code>log[2](X)</code> additional levels to be researched before the next level takes longer to research with the expanded capacity than level <code>M + 1</code> would have taken with the pre-expansion production capacity.
#*For example, if one expands production capacity by a factor of 10, they will be able to research at least <code>floor(log[2](10)) = 3</code> and at most <code>ceiling(log[2](10)) = 4</code> additional levels in a given technology before the exponential increase in price negates the speed benefits of their ×10 capacity expansion.
#The cumulative price of the first <code>N - F</code> levels of infinite technologies whose underlying equation is an arithmetic series is <code>(N - F) × (P[N] + P[F + 1]) ÷ 2</code>; i.e, <code>N - F</code> times the mean of the prices of the first and last "infinite" level. For the [[Follower robot count (research)]], an additional <code>900 × (N-F)</code> need to be added.
#*Expanding production capacity by a factor of <code>X</code>, as above, will in this case allow an additional <code>N × (X - 1)</code> levels to be researched before the benefit of the expansion is wiped out (i.e., research progress speed drops to or below what it was pre-expansion).
#The cumulative price of the first '''''N''''' levels of '''artillery shell shooting speed''', the sole infinite technology whose underlying equation is a powers-of-three geometric series (equation type (2)) is <code>1.5 × P[N] - 0.5 × P[1]</code>; i.e., 1.5 times the price of the final researched level, less half the price of the first level.

Note that these prices reflect '''research units''', which will not be equal to science packs if [[productivity module|productivity modules]] are used in labs. (In that case, the science pack requirement will be lower.)

=== Infinite productivity research limits {{SA}} ===

All recipes have a maximum productivity of 300%. This was [https://factorio.com/blog/post/fff-375 primarily done to prevent infinite resource exploits] involving the [[recycler]]{{SA}} and its 25% return of input items. This cap puts a hard limit on the effectiveness of most infinite productivity researches. You can research past level 30 of these technologies, but it will have no practical effects.

Note that miners are not crafting machines that execute recipes, nor are labs. As such, [[mining productivity (research)]] and [[research productivity (research)]]{{SA}} have no limit.

The [[Railgun shooting speed (research)|railgun turrets shooting speed]] is tied to its [https://forums.factorio.com/viewtopic.php?p=625202#p625202 animation], making the max shooting speed bonus +0.36/s. You can research past level 5, but it will have no practical effect on the [[railgun turret]], however it '''will''' continue to increase the shooting speed of the [[railgun]] past level 5.

Captive biter spawner

2025-06-30T07:55:25Z

Domisum: Quality has no effect on starvation rate

{{Languages}}
{{:Infobox:Captive biter spawner}}
{{About/Space age}}
A '''captive biter spawner''' is a special production building that is initially unlocked by researching [[captivity (research)]]{{SA}} with [[agricultural science pack]]s{{SA}} and is used to produce [[biter egg|biter eggs]]. A captive biter spawner has no [[module]] slots, is unaffected by [[beacon]]s, and cannot be connected to either circuit or logistic networks. A captive spawner cannot be removed by the player or [[construction robot]]s, but can be destroyed via weapon fire, at which point it will spawn a small biter.

== Biter egg production ==
Captive biter spawners are solely used to produce [[biter egg|biter eggs]], for which they are the only source in the game. Producing biter eggs does not require setting a recipe or providing any ingredients other than a constant influx of fuel in the form of [[bioflux]]. A captive biter spawner can hold a maximum of 100 biter eggs, which they produce at a rate of 5 eggs every 10 seconds, or 0.5 /s. The production cycle continues when the output slot is full, even though no additional eggs are being produced. Biter eggs held in the output slot will not start to spoil until removed.

== Obtainment ==
Initially, the only way to create a captive biter spawner is by firing a [[capture bot rocket]]{{SA}} at a [[Enemies#Nests|biter spawner]] on [[Nauvis]], which will slowly transform the spawner into a captive one. After reaching [[Aquilo]]{{SA}} and researching [[captive biter spawner (research)]], the player can craft captive biter spawners themselves, which can be manually placed. While in the player's inventory or another container, a captive spawner has a spoilage time of 30 minutes, at which point it will turn into a behemoth biter.

== Food consumption ==
A captive spawner requires a constant supply of [[bioflux]]{{SA}}. Starving spawners will stop producing biter eggs and lose health at a rate of 1 per second, regardless of quality. If a captive spawner's health reaches zero, it will transform back into a normal spawner and will have to be captured again.

Previously captured and then starved [[Enemies#Nests|biter spawners]] are normally not targeted by automated weapon systems, including [[turret]]s, [[artillery]], and [[spidertron]]'s automatic rocket launchers, but they will still be targeted by [[capture bot rocket]]s. They still consume [[pollution]] and spawn biters which are affected by the [[Enemies#Evolution|evolution factor]].

[[Bioflux]]{{SA}} is used for food. One item of bioflux has an energy value of 6 MJ, and since the captive biter spawner consumes 100 kW of food, each item of bioflux will last for exactly one minute. With one normal quality item of bioflux lasting for two hours before it [[spoilage|spoils]], this means that 120 items of bioflux of the same age may be consumed by a single captive biter spawner before any of them spoil.

== Quality ==
Captive biter spawners with a higher quality level will ''not'' yield higher quality [[biter egg]]s.

If a captive biter spawner reverts back into a biter spawner for any reason, it will retain the quality it had as a captive biter spawner. This resulting spawner will spawn biters of the same quality, which will have the capability of forming expansion groups that will also retain their quality level upon successful expansion - creating more quality biter or [[Enemies#Spitters|spitter]] spawners, and even quality [[Enemies#Worms|worms]]. Failing to contain such reverted spawners can lead to the planet becoming populated by higher quality enemies.

Oxide asteroid chunk

2025-06-21T07:55:03Z

Domisum: Add slots per tile for cargo bay

{{Languages}}
{{:Infobox:Oxide asteroid chunk}}
{{Stub}}
{{About/Space age}}
'''Oxide asteroid chunk''' is a resource gathered by [[asteroid collector]]s and processed in [[crusher]]s. It is the main source for [[ice]], used to make [[thruster oxidizer]], and [[calcite]]. It is dropped from oxide asteroids, which are found in trace amounts near the first 4 planets but is incredibly abundant when traveling to [[Aquilo]]. It can also be used in asteroid reprocessing.

As asteroid chunks stack size is only 1, [[Transport belt|belts]] can hold more chunks per tile (8) than [[cargo bay]]s (normal quality: 1.25), even if they are legendary (3.125).

Pollution

2025-06-15T06:30:54Z

Domisum: Restructure paragraph into production, consequences and mitigation

{{languages}}
[[File:Pollution.png|300px|thumb|Example of in-game pollution (red squares) in the map]]
[[File:pollution_gui.png|300px|thumb|Pollution tab in the production GUI.]]

Pollution is represented as an abstract "cloud", updated [[Map_structure#Chunk|per chunk]] every 64 [[Time#Ticks|ticks]] (which is 4 ticks more than a game-second). It is visible on the map if the "pollution" setting is on, and appears as a blocky red cloud.

It is produced by many buildings involved in processing items and spreads outwards at a steady rate.

The [[Enemies#Evolution|evolution factor]] is not increased by the spreading/absorbed pollution, but by the pollution produced by all the player's [[Pollution#Polluters|machinery]] at every tick. This means that no matter how hard the player tries to contain the pollution, [[enemies]] will still evolve at the same rate. They just won't attack the player as frequently. The pollution cloud is used to trigger biter attacks and determines the size of the attacks.

Pollution settings can be changed via [[map generator|map generation]] settings, or can be disabled entirely.

== Pollution spread ==

As soon as a chunk has reached 15.0 pollution it starts spreading in all four cardinal directions at a rate of 2% per 64 ticks. Pollution can generate new chunks if it needs to spread to them.

For example, a chunk with 400.0 pollution and 4 adjacent chunks with 100.0 pollution each, raises the pollution in all adjacent chunks by 8.0 while reducing its own pollution by 32.0. But every one of the 4 surrounding spreads 2.0 pollution "back" to the center chunk, so it only loses 24.0 + [[Pollution#De-polluters|absorbed value]].

== Pollution dissipation==

* Every [[Map_structure#Chunk|chunk]] (32x32) of map slowly reduces the pollution it covers (See [[#Chunks]]). So the more the pollution spreads, the more is absorbed.
* [[Tree]]s also absorb some pollution (See [[#Trees]]).
* [[Enemies#Spawner|Spawners]] absorb a great amount of pollution, and use this to assign enemies to attacks.

== Native life ==
Pollution attracts [[Enemies#Biters|biters]] to the Player's factory. Biters who find themselves in a polluted area will attempt to reach the source of pollution and destroy it. Any [[water]] near the source of pollution will turn green, which is a visual-only effect. The effect can be turned off by disabling animated water in the graphics settings.

If a chunk's pollution is greater than 20, each enemy spawner absorbs 20 + 0.01 * [chunk's pollution] every 64 ticks, otherwise it absorbs 3 times the amount of pollution needed for the most expensive unit it can spawn for the current evolution factor.

Higher pollution values decrease the time it takes for biters to join the attack force. After a certain amount of pollution is absorbed the spawner sends one of its biters/spitters to a rendezvous point. Every 1 to 10 minutes (random) the mustered biters launch an attack. If not all biters have arrived at the rendezvous point by that time, they will wait up to an additional 2 minutes for stragglers.

This also applies to [[Enemies#Wrigglers|pentapods]]{{SA}} on [[Gleba]]{{SA}}.

Required pollution to add an additional biter/spitter to the attack wave:

=== De-polluters ===

==== Spawners ====
Every 64 ticks, spawners absorb pollution until they have absorbed more than 3 times the amount needed to send the [[Enemies#Creatures|most expensive unit]] at the current evolution level.

If they have not absorbed more than that threshold, they will absorb 20 + 0.01 * [chunk's pollution] and check the threshold again.

Note that absorbing pollution is not for spawning biters, but for sending biters to an attack group. Spawners will spawn enemies regardless of pollution absorption until they reach their spawn limit.

[[Captive biter spawner]]s {{SA}} absorb 1 pollution per minute. Captive spawners which have decayed to the wild type use the rules above for pollution absorption.

==== Chunks ====
Every chunk has a natural absorption rate per second which is determined by the sum of the pollution absorption of its floor [[tile]]s.

|-
| Special tiles (Lab tiles, tutorial grid, Water Wube) || 0 || 0
|-
| Out of map || -0.0001 || -6.144
|-
|}

==== Trees ====

Every single [[tree]] absorbs a small amount of pollution in its chunk per second. If the total pollution in a chunk is above 60 units, once per second some of the trees in that chunk each have a chance to either lose one stage of leaves (33% or 50% damage) or have their leaves become one stage more gray (6.7% damage). Regardless of whether the tree loses leaves or gets grayer, 10 pollution are absorbed by the tree. 
A tree stops losing leaves/becoming more gray once the sum of its gray percentage and its leaves lost percentage is above 120%. Half of trees stop their leaf progression one stage earlier. As the grayness and leaf stage are then locked for that tree forever, it is possible for trees to keep some leaves in heavily polluted chunks but in turn be very gray, or the other way around. 
The less dense the leaves, the slower the tree absorbs pollution, however tree grayness does not affect pollution absorption.

==== Biochambers{{SA}} ====

The [[biochamber]] "generates" negative pollution, at a base rate of -1 per minute. This effectively means that the building removes pollution while active.

This pollution value works like any other building, including how it scales with energy consumption. That is, if a module affects its energy consumption, the pollution is proportionately higher as well. However, because the base rate is negative, the Biochamber "generates" more negative pollution. [[Productivity module]]s and their direct pollution increase work in a similar way, boosting the negative pollution of the building even more.

== Spores {{SA}} ==

Spores are a unique form of pollution on Gleba. They are generated when [[yumako tree]]s or [[jellystem]]s are harvested (not destroyed). Machines '''do not''' produce spores, with the only exception being the [[agricultural tower]]. Spores are displayed as green squares on the map.

Spores will attract the native inhabitants of Gleba, [[pentapod]]s.

Spores are consumed by [[Egg raft]]s (pentapod nests) and most tiles. Biochambers do not absorb spores.

Domisum: Note about biochamber pollution absorption

{{languages}}
[[File:Pollution.png|300px|thumb|Example of in-game pollution (red squares) in the map]]
[[File:pollution_gui.png|300px|thumb|Pollution tab in the production GUI.]]

Pollution is represented as an abstract "cloud", updated [[Map_structure#Chunk|per chunk]] every 64 [[Time#Ticks|ticks]] (which is 4 ticks more than a game-second). It is visible on the map if the "pollution" setting is on, and appears as a blocky red cloud.

It is produced by many buildings involved in processing items and spreads outwards at a steady rate.

The [[Enemies#Evolution|evolution factor]] is not increased by the spreading/absorbed pollution, but by the pollution produced by all the player's [[Pollution#Polluters|machinery]] at every tick. This means that no matter how hard the player tries to contain the pollution, [[enemies]] will still evolve at the same rate. They just won't attack the player as frequently. The pollution cloud is used to trigger biter attacks and determines the size of the attacks.

Pollution settings can be changed via [[map generator|map generation]] settings, or can be disabled entirely.

== Pollution spread ==

As soon as a chunk has reached 15.0 pollution it starts spreading in all four cardinal directions at a rate of 2% per 64 ticks. Pollution can generate new chunks if it needs to spread to them.

For example, a chunk with 400.0 pollution and 4 adjacent chunks with 100.0 pollution each, raises the pollution in all adjacent chunks by 8.0 while reducing its own pollution by 32.0. But every one of the 4 surrounding spreads 2.0 pollution "back" to the center chunk, so it only loses 24.0 + [[Pollution#De-polluters|absorbed value]].

== Pollution dissipation==

* Every [[Map_structure#Chunk|chunk]] (32x32) of map slowly reduces the pollution it covers (See [[#Chunks]]). So the more the pollution spreads, the more is absorbed.
* [[Tree]]s also absorb some pollution (See [[#Trees]]).
* [[Enemies#Spawner|Spawners]] absorb a great amount of pollution, and use this to assign enemies to attacks.

== Native life ==
Pollution attracts [[Enemies#Biters|biters]] to the Player's factory. Biters who find themselves in a polluted area will attempt to reach the source of pollution and destroy it. Any [[water]] near the source of pollution will turn green, which is a visual-only effect. The effect can be turned off by disabling animated water in the graphics settings.

If a chunk's pollution is greater than 20, each enemy spawner absorbs 20 + 0.01 * [chunk's pollution] every 64 ticks, otherwise it absorbs 3 times the amount of pollution needed for the most expensive unit it can spawn for the current evolution factor.

Higher pollution values decrease the time it takes for biters to join the attack force. After a certain amount of pollution is absorbed the spawner sends one of its biters/spitters to a rendezvous point. Every 1 to 10 minutes (random) the mustered biters launch an attack. If not all biters have arrived at the rendezvous point by that time, they will wait up to an additional 2 minutes for stragglers.

This also applies to [[Enemies#Wrigglers|pentapods]]{{SA}} on [[Gleba]]{{SA}}.

Required pollution to add an additional biter/spitter to the attack wave:

Every chunk has a natural absorption rate per second which is determined by the sum of the pollution absorption of its floor [[tile]]s.

{| class="wikitable"

|-
|}

==== Trees ====

Every single [[tree]] absorbs a small amount of pollution in its chunk per second. If the total pollution in a chunk is above 60 units, once per second some of the trees in that chunk each have a chance to either lose one stage of leaves (33% or 50% damage) or have their leaves become one stage more gray (6.7% damage). Regardless of whether the tree loses leaves or gets grayer, 10 pollution are absorbed by the tree. 
A tree stops losing leaves/becoming more gray once the sum of its gray percentage and its leaves lost percentage is above 120%. Half of trees stop their leaf progression one stage earlier. As the grayness and leaf stage are then locked for that tree forever, it is possible for trees to keep some leaves in heavily polluted chunks but in turn be very gray, or the other way around. 
The less dense the leaves, the slower the tree absorbs pollution, however tree grayness does not affect pollution absorption.

==== Biochambers{{SA}} ====

The [[biochamber]] "generates" negative pollution, at a base rate of -1 per minute. This effectively means that the building removes pollution while active.

This pollution value works like any other building, including how it scales with energy consumption. That is, if a module affects its energy consumption, the pollution is proportionately higher as well. However, because the base rate is negative, the Biochamber "generates" more negative pollution. [[Productivity module]]s and their direct pollution increase work in a similar way, boosting the negative pollution of the building even more.

== Spores {{SA}} ==

Spores are a unique form of pollution generated on Gleba. They are made when [[yumako tree]]s or [[jellystem]]s are harvested (not destroyed). Spores do not attract biters, but rather attract pentapods. Spores are consumed by most tiles. They are displayed as green squares on the map. Machines '''do not''' produce spores, with the only exception being the [[agricultural tower]].

Rocket silo

2022-03-08T00:12:23Z

Domisum: Add inserter swing time to calculation of max throughput

{{languages}}
{{:Infobox:Rocket silo}}

The '''Rocket silo''' is currently the only win condition. Once the silo has been built and placed it can be filled with [[low density structure]]s, [[rocket fuel]], and [[rocket control unit]]s, which will allow [[rocket part]]s to be created within the silo.

In order to launch a rocket, 100 rocket parts need to be crafted. Each rocket part requires 10 low density structures, 10 rocket fuel, and 10 rocket control units.

When all rocket parts have been completed, the rocket silo interface is at 100% and allows the player to input an item as cargo. Launching the rocket empty or with any payload will complete the game, displaying a victory screen. The screen shows all kills and time played, and offers the player a choice of exiting the current game, continuing play, or viewing the [[replay system|replay]].

Launching the rocket with a [[satellite]] as cargo produces 1000 [[space science pack]]s, which are generated inside the silo. The silo interface includes the option to "Auto-launch with cargo", which will immediately, automatically launch the rocket if it is completed ''and'' cargo has been inserted as payload.

Building a silo requires, among other things, [[electric engine unit]]s, [[engine unit]]s, and [[processing unit]]s, which must be produced in [[assembling machine]]s and cannot be crafted by hand from raw materials. The rocket itself can also only be produced in the silo. The rocket silo accepts [[productivity module|productivity modules]], and due to the high resource requirements to craft a rocket is a good candidate for their use.

The rocket silo result inventory can hold up to 2000 space science packs (one stack), the equivalent of 2 full rocket launch results. When receiving science packs from a launched satellite, the game discards (destroys) all space science packs that exceed the capacity of the rocket result inventory. The "Auto launch with cargo" checkbox does '''not''' check if the rocket result inventory can hold the expected space science packs, this has to be manually ensured by the player, for example through the [[circuit network]].

== Maximum throughput ==

The duration of the rocket launch animation is 2420 [[Time#Ticks|game-tick]]s, or 40.33 seconds [https://www.reddit.com/r/technicalfactorio/comments/f753iu/empirical_measurements_on_the_silo_animation/fibsvn6/]. This is the time from when the rocket is finished to when production on the next rocket can start, but does not include the time to insert the payload. Unlike rocket part crafting, the animation's duration is not affected by any modules or beacons. This may become a factor if one is planning to launch rockets at high frequency. An inserter requires half a turn to insert the satellite, which takes 13 ticks (0.22 seconds), assuming a fast/stack inserter is used.

The shortest crafting time achievable for 100 rocket parts in a single silo is ~20.60 seconds; i.e., slightly longer than what would be required to launch 1 rocket / minute. This crafting time is achieved using the maximum of 20 beacons with all [[speed module 3|speed modules 3]], plus 4 [[productivity module 3|productivity modules 3]] in the silo itself. The latter not only cuts resource requirements by almost 30%, but is also faster than using more speed modules 3 in the silo.

Thus, the largest space science pack output one can obtain out of a single rocket silo is about 981 per minute. (~= 1000 * 60 / (40.33 + 20.60 + 0.22)‬)

The rocket silo, which is used to win the game, is directly connected to the following game-win-based achievements:

== Trivia ==

The rocket can, technically, accept any item as cargo; however, most will do nothing in particular and simply waste the launch. Notable exceptions include:

{{Spoiler|button-text=Spoiler! Click to view.|message=
<ul><li> [[Vehicle]]s : When a vehicle is inserted into the payload slot, the player can enter the rocket like they would any other vehicle, then launch and ride it.
<ul><li> This allows a fast-moving view of one's base (as the game world is internally 2-dimensional, the rocket actually simply moves north along the map), and then returns the player next to the launching silo once the launch animation has finished.
<ul><li> If all space near the rocket silo is occupied, the player is placed at spawn instead. </li></ul>
<li> It also wastes the launch, as the rocket's sole payload slot is occupied by the vehicle, rather than a satellite. (Having any number of satellites in the car's trunk or the "astronaut"s inventory does not count.) </li></ul></li>
<li>[[Raw fish]]: Grants the "So long and thanks for all the fish!" achievement. Other than this, it also wastes the launch.</li>

Fluid system

2022-01-11T22:05:19Z

Domisum: Contrast advantages of railway fluid transport methods

{{Languages}}
'''Fluids''' are non-solid items, such as [[water]] and [[oil]]. They can normally only exist inside entities for fluid handling (like [[pipe]]s), and buildings that have fluids as input ingredients or products (like an [[oil refinery]]).

== Fluids ==
[[File:fluids_gui.png|thumb|300px|right|"Fluids" tab on the [[production statistics]] screen.]]
The following fluids are available in-game:

: {{Imagelink|Water}} {{Imagelink|Crude oil}} {{Imagelink|Petroleum gas}} {{Imagelink|Light oil}} {{Imagelink|Heavy oil}} {{Imagelink|Lubricant}} {{Imagelink|Sulfuric acid}} {{Imagelink|Steam}}

== Mechanics ==
Fluids cannot be carried by the player, moved using [[inserters]], dropped on the ground, nor stored in chests, unless the fluids are stored in [[barrel]]s. They cannot be spilled or even dumped in a lake, and are counted in continuous fractions, rather than discrete integers. 
When the player picks up a structure that contains fluids, the contained fluid will try to flow into connected structures and any excess fluid that does not fit is destroyed.

=== Storage ===

In the game, fluid is held in entities that behave as vessels (fluid boxes) of a defined size (volume). The vessels automatically connect to each other if their inputs/outputs are adjacent (pipes connect to all directions) and allow fluids to flow between them.

The '''volume''' of fluid contained in a fluid box is a value between 0 and the maximum volume. For instance, the pipe can hold 100 units of fluid, therefore the value in the pipe can be a number between 0 and 100. The '''level''' of fluid in a given entity is manifested by a percentage of the entity's maximum volume that is being occupied by a fluid. It can be observed in pipes and tanks; they have windows through which the fluid is seen at a certain level, or perhaps even as just a small trickle.

=== Fluid mixing ===
[[File:Pipe_GUI.png|right|frame|GUI of a pipe inside a fluid system containing mixed fluids. Clicking the trash can icon next to a fluid will flush that fluid from the system.]]
The game will prevent players from accidentally mixing fluids when placing most buildings, e.g. [[pipe]]s containing different fluids cannot be placed directly next to each other. However, not every possible case of fluid mixing is considered, so the player may still mix fluids accidentally or by purposely working around the building restrictions. A fluid system containing mixed fluids can be cleared of the undesired fluids in the GUI of a pipe or [[storage tank]] that is part of that fluid system. Fluids that are flushed from pipes or storage tanks are deleted permanently.

In a fluid system that contains mixed fluids, the alt-mode fluids icons on its pipes/storage tanks will reflect the fluid that is contained in that specific structure. So, it may look like a fluid system only contains one fluid when looking at the alt-mode icons, when in reality it contains multiple fluids which are located in some other connected structures. The GUI of a connected pipe or storage tank will always show all fluids contained in the fluid system. 
This means that if the game disallows connecting two pipes that look like they contain the same fluid with "Cannot connect systems with different fluids", one of the fluid systems contains multiple fluids. This can solved easily by opening the GUIs of the pipes that the game refuses to connect which will show the extra fluid and allow flushing it from the fluid system.

=== Flow ===

All connected tanks and pipes are treated as a single vessel in that ''the level of fluid must be equal in all parts'', to even out pressure exacted by a higher fluid level on smaller ones. This is why level is also often referred to as ''pressure'', even though pressure is actually caused by a difference in level between two entities. All flow of fluid that happens between pipes is to achieve this balance (pumps practically ignore it and buildings disrupt it; more on that further below). The flow rate between pipes is dependent on pressure (the difference in level between the adjacent entities), it becomes slower as pipes even their levels out.

Coming back to how the 'level' is defined, this also means that all connected pipes and tanks attempt to even out to the same percentage of their respective volumes. For example, if 12,550 units of fluid are left to flow into a storage tank of 25,000-unit capacity with one pipe of 100-unit capacity connected, there will be 12,500 units in the storage tank and 50 units in the pipe, both being filled to the same '''percentage''' (50%) of their capacities, even though the amounts themselves are unequal.

Machines that produce fluids put them in their output slots, which are related to a specifically labeled output pipe socket somewhere on the machine (pressing Alt reveals the labels). The slot will attempt to empty itself into the entity connected to the machine's socket, unless it is full, or contains a non-matching fluid. Machines that consume fluids also have an accordingly labeled pipe input socket. If an entity containing the correct fluid is connected to it, the machine will start behaving like a pipe that can never be filled, meaning the fluid from connected pipes and tanks drains into the machine at a fixed rate, until the machine's input slot is full. There may be machines that have pipe sockets for both input and output (like a [[electric mining drill|drill]] placed over [[uranium ore]]). They then drain the fluid for themselves first, and once full, behave as a regular pipe that attempts to even out its level with adjacent entitites. If there are multiple output/input sockets for one fluid on a machine, their activity is distributed to them equally unless some of them are blocked/full.

=== Temperature ===
Temperature is currently only relevant in heating water as a medium for power generation. Even though all fluids in the game have a temperature value, it is generally the default 15°C.

Energy, whether harnessed from [[fuel]] in [[boiler]]s, or from [[Nuclear power (research)|nuclear power]] through [[heat exchanger]]s, can be used to turn [[water]] to [[steam]], being a [[Energy and work|liquid form of work]]. Steam holds energy at a ratio of 0.2 kJ per °C per unit. In other words: 0.2 kJ of work is necessary to heat a unit of steam by one °C. Since steam/water is set to have a maximum temperature of 1000°C and minimum of 15°C, the most work that can be done on one unit is 197 kJ.

In practice, this is barely utilized in a great variety: Boilers only output steam of 165°C temperature, and heat exchangers only output 500°C hot steam, never hotter, never colder; if insufficient energy is supplied, the heaters do not output steam altogether. The steam also does not grow colder over time. Using the 165°C steam in a [[steam engine]] has the same effect as using it in a [[steam turbine]], although it is impractical, since turbines are made to consume 500°C (superheated) steam, generating proportionally more power. All of this makes for no need of exact calculations.

== Transport ==
Fluids can be transported through pipelines, barrels, or railway. It is generally practical to use piping for short-distance distribution to machines (or barrelling, if there is need to use belts), and railway transportation for longer distances.

=== Pipelines ===
[[File:pipes_carrying_fluids.png|thumb|312px|Eight pipelines, each carrying a different fluid.]]

'''[[Pipe|Pipes]]''' are the most basic way to channel fluids from A to B. They automatically connect to any adjacent pipe and can do so to all four cardinal directions simultaneously. [[Pipe to ground|Underground pipes]] only work in two opposite directions, linking to another underground pipe on one side, and to another entity on the other. If a pipe section becomes too long without using pumps, all fluid inside it will be "spread thin", resulting in very slow flow and preventing machines to use its contents effectively. '''[[Storage tank|Tanks]]''' behave the same as pipes, except their volume is much greater, which can cause this inconvenience over a much smaller distance if multiple tanks are used. Underground pipes can help alleviate this issue; although they can connect a distance of up to 10 tiles, their volume is always equivalent to two pipes.

'''[[Pump]]s''' use electrical power to transfer fluids in one direction very quickly. They also block any back-flow, which means they can pressurize a section of piping, filling it as much as possible. This is very useful to counteract the "thin spread" outlined above, among other things. They can also be disabled using the [[circuit network]] which stops fluid flow through the pump.

The table below shows how fast will fluid flow in a pipeline with a certain frequency of pumps. If a higher flow rate is desired, pumps should be placed more frequently. Because underground pipes only count as 2 regular pipes in terms of volume, a full-length section only counts as two pipes in this table, if a pump is placed between each underground section. Placing a filled storage tank before a pump ensures maximum possible flow rate and is therefore a suitable start of any pipeline.

|}

=== Barrels ===
'''[[Barrel]]s''' are used by [[Assembling machine]]s to effectively "bottle" fluids into an item that can be handled like any other item; carried in an inventory, placed in chests and handled by [[Inserters]]. This allows the player to transport fluids via the [[belt transport system]] and the [[logistic network]]. Assembling machines are also used to empty the barrels, depositing their contents to pipes and leaving an empty barrel for another use.

=== Railway ===

'''[[Railway]]''' is another method of transporting fluids, and can be conducted in two ways: Either the fluids are directly pumped into a [[fluid wagon]], or they are poured into barrels and loaded into [[cargo wagon]]s. Both methods have their advantages:

'''Advantages of using fluid wagons'''
* Faster loading and unloading
* Higher capacity (25k vs 20k)

'''Advantages of using barrels in cargo wagons'''
* A single cargo wagon can transport multiple types of barrelled fluid (and regular items at the same time)
* Cargo wagons, [[Fluid wagon#Troubleshooting|as opposed to fluid wagons]], don't need to be perfectly aligned to be (un-)loaded, allowing for more flexible train station designs

{{:Infobox:Mining productivity (research)}}

Mining productivity is a research that increases the resource output of [[mining drill]]s and [[pumpjack]]s by 10% per level. Unlike productivity from [[productivity module]]s, there are no downsides. Any ore that is produced by the productivity bonus is free, it does not deplete the resource under the miner.

Mining productivity is a research that increases the resource output of [[mining drill]]s and [[pumpjack]]s by 10% per level. Unlike productivity from [[productivity module]]s, there are no downsides. Any ore that is produced by the productivity bonus is free, it does not deplete the resource under the miner.

{{Languages}}
[[File:player_attacked_by_biters_small.png|thumb|300px|right|Red flashing while taking damage.]]Taking '''damage''' is the effect of lowering the health of the [[player]], [[enemies]] or other entities.
== Overview ==
In Factorio, entities have health, can die/be destroyed, and have resistances. ''Damage'' is defined as the concept of lowering an entity's health by using an attack, such as a gun firing at it, or a biter chewing on it. An entity's resistances will define exactly how much damage the entity will take off of an arbitrary attack.

The player's maximum health is 250 (without [[energy shield]]s). Other entities' health values are listed in their individual entries.

== Achievements ==
The concept of damage is directly connected to the following achievements:
{{Achievement|run-forrest-run}}
{{Achievement|pyromaniac}}
{{Achievement|steamrolled}}
{{Achievement|golem}}
{{Achievement|watch-your-step}}

== Damage types ==

=== Piercing power ===
Piercing power is present with [[tank]] ammunition. It determines how much HP of enemies can a projectile damage before it is no longer able to travel further. To penetrate an enemy, the enemy has to be killed by the projectile, and the damage dealt for the kill must be less than current piercing power.[https://forums.factorio.com/viewtopic.php?f=5&t=30917] The damage dealt also decreases piercing power. For example, shooting medium biters with 75 health with a cannon shell of 300 piercing power means that the shell will pierce through 4 medium biters, killing them, and still destroy/damage one more target.

== Resistance ==
Resistance has two aspects:
=== Decrease, or "flat" resistance ===
Decrease resistance decreases the damage by specified number as long as the resulting damage wouldn't be less than 1. If the result damage would be less than 1, an alternate formula is used.
Let R denote the flat resistance value, D the incoming damage, and M the modified damage, after accounting for flat resistance. Then

if R+1<D

<code>M=D-R</code>

otherwise if D>1

<code>M=1/(R-D+2)</code>

otherwise

<code>M=1/(R+1)</code>.

If flat resistance matches or exceeds the raw damage, then modified damage is asymptotic towards 0, as shown by following example table:

{| class="wikitable"
|-
! Damage !! Flat Resistance !! Modified damage (with 0% resistance)
|-
| 5 || 0 || 5
|-
| 5 || 1 || 4
|-
| 5 || 2 || 3
|-
| 5 || 3 || 2
|-
| 5 || 4 || 1
|-
| 5 || 5 || 1/2
|-
| 5 || 6 || 1/3
|-
| 5 || 7 || 1/4
|-
| 5 || 8 || 1/5
|-
| ... || ... || ...
|}

=== Percentage resistance ===

Percentage resistance reduces the damage by the specified percent. It is applied ''after'' flat/decrease resistances when both are present and thus changes the 'modified damage' value above, decreasing it by the specified percentage. If the value is 100%, the entity is immune to the damage. This is the only way to have an entity immune to a type of damage, as flat reduction cannot reduce damage beneath 1.

As an example, an entity with 25% resistance to physical damage hit with a bullet dealing 100 physical damage would take 75 damage instead of 100.

The formula used for percentage resistance to damage is as follows:

Let M denote the flat-resistance-modified starter damage, and let P denote the percentage resistance (in decimal form, so 25%=0.25), and let F denote final damage.

<code>F = M * (1 - P)</code>

--------

In Factorio, resistances are displayed in the UI as follows:

Decrease resistance/Percentage resistance (Damage type)

So, an entity that displays 10/20% resistance to fire has 10 flat resistance and 20% percent resistance to fire. If the aforementioned entity were to take 30 fire damage, they would instead take 16 damage, after resistances were applied.

The formula used for the above:

16final damage = (30initial raw damage - 10flat resist) * 0.820% resistance

== Combined formulas ==
Let D denote the raw incoming damage (of applicable type), R denoted the flat resistance value (against damage of the applicable type), P the percentage resistance (against damage of the same type) in decimal form (e.g. 20%=0.2), and let F denote the final damage (of applicable type) dealt to the target.
=== If R+1<D ===
F = (D - R) * (1 - P)
=== otherwise if D>1 ===
F = (1 - P) / (R-D+2)
=== otherwise ===
F = (1 - P) / (R+1)
