{{About/Space age}}
[[File:asteroids_anim.gif|right]]'''Asteroids''' are floating minerals found in space. There are four types of asteroids in [[Space Age]]: metallic, carbonic, oxide and promethium. Promethium asteroids are only encountered when en route to the [[shattered planet]]. Asteroids appear around stationary [[space platform]]s. If a space platform is travelling through space with a [[thruster]], asteroids are encountered much faster. [[Asteroid collector]]s can collect [[Asteroids#Asteroid Chunks|asteroid_chunks]]. The resources collected from asteroid chunks can be fed into a [[crusher]], grinding the chunks into useful resources.

When travelling through space, asteroids will appear in front of the space platform and damage it on contact. This means that [[turret]]s should be properly placed (mainly at the top) of the platform to prevent this and asteroid collectors should be used to collect the chunks.

The density of asteroids can be seen by going to the [[Remote view]] > '''Surfaces''' > '''Space Map''' and alt-clicking on the interplanetary route to bring up the route in Factoriopedia, or by searching "route". The graph will show a white vertical line overlay on the asteroid graph corresponding to the ship's position when underway.

'''Note:''' Promethium asteroids have twice the health of the three standard asteroid types (200/800/4000/10000)

== Asteroid chunks ==
'''Asteroid chunks''' are the smallest asteroids in the game, serving as the sole resource source in space. Due to their size and low mass, these small chunks will not damage the player's space platform when colliding with it, as larger asteroids do. They will also slowly gravity to the space platform, as if the platform has a gravitational pull, making it easier to collect them. To maintain sustainability, space platforms can be equipped with both [[asteroid collector]] and [[crusher]]. These chunks come in four distinct varieties, each of which can be processed into valuable materials using crushers. [[Advanced_asteroid_processing_(research)|Advanced asteroid processing research]] unlocks the ability to extract additional materials from these chunks.

DataCpt: Added missing military science pack to railgun shooting speed

{{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 [[Research|researched]] in [[lab]]s using [[science pack]]s.

Every technology needs a certain amount of science packs per science pack type to be researched, 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.

== Achievements ==
{{Achievement|tech-maniac}}
* Completing infinite technologies of any level is not required for '''Tech maniac'''. All non-infinite levels of technologies that have infinite continuations are still required.
{{clear}}
== 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.

Steam

2025-01-21T02:32:14Z

DataCpt: Added links where their exclusion seemed wrong

{{Languages}}
{{:Infobox:Steam}}
'''Steam''' is a [[fluid system|gas]] created by heating water in a [[boiler]] or [[heat exchanger]], or through [[acid neutralisation]]{{SA}}. After being distributed via [[pipe]]s, steam can be used to generate electricity via [[steam engine]]s and [[steam turbine]]s. Steam is also used in [[coal liquefaction]] in [[oil refinery|oil refineries]]. Since steam is a fluid, it can be stored in a [[storage tank]].

== Power generation ==
The amount of energy contained in steam is linearly proportional to its temperature (minus 15°C ambient temperature). The energy storage of steam is exactly ''200 joule / unit / degree Celsius'', so every degree increase in temperature of a single unit of fluid requires exactly 200 joules.

In all cases, steam produced in [[boiler]]s is 165°C and steam from [[heat exchanger]]s or [[acid neutralisation]]{{SA}} is 500°C. Higher temperature steam equates to a higher energy density of the same number of units of steam. Steam suffers no thermal losses sitting or flowing through [[pipe]]s or [[storage tank]]s; the energy put into water to create steam is the same amount of energy you get back out from it since both steam engines and turbines are 100% efficient.

For example, a storage tank that holds 25000 units of Steam at 165°C contains:
<pre style="width: 68%;padding-right: 0em;">(200 J / unit / °C) * 25000 units * (165°C − 15°C) = 750 000 000 joules = 750 MJ</pre>

A storage tank holding 25000 units of Steam at 500°C thus contains 2.425 ''giga''joules of energy, a surprisingly large amount equal to 485 fully charged [[accumulator]]s!
<pre style="width: 68%;padding-right: 0em;">(200 J / unit / °C) * 25000 units * (500°C − 15°C) = 2 425 000 000 joules = 2.425 GJ</pre>

If the temperature of the steam is lower than the [[steam engine]] or [[steam turbine]] can handle, then the power output will be lower than optimal, but no energy will be wasted. However, if the temperature of the steam exceeds the maximum temperature of the steam engine or turbine, then the power output is capped at maximum, and the extra energy in the steam is wasted. Other than this difference, either steam engines or turbines can be used to generate power off of steam from any source.

== Trivia ==
* The fill meter on steam storage tanks fills from the top instead of from the bottom.
* Steam is the only pre-[[Space Age]] fluid that cannot be stored in [[barrel]]s.
* Assuming perfect efficiency of boilers and heat exchangers, the thermal energy content of steam implies that one unit represents 47.9g of water, meaning a full tank contains 1195 kg of steam.
* Because burner devices are not permitted on [[Space platform]]s{{SA}}, and acid neutralization is [[Vulcanus]]-exclusive, the only way to get steam on platforms (either for power or liquefaction) is with [[heat exchanger]]s power by [[nuclear reactor]]s
