	However, while lower efficiency than a Gas Fuel Generator, in terms of energy output per mole of fuel input, a [[Stirling Engine]] is a practical and effective first step for cooling the output due to the fact that it generates power from cooling, rather than consuming power to cool the output (such as with an [[Air Conditioner]]). Depending on the exact setup, and how efficiently the Stirling Engine can be cooled (best on cold non-vacuum planets like Europa and Mars), it's possible for the Stirling Engine to offset the power cost of H2 Combustor, Filtration, and the entire rest of the cooling system, resulting in a zero-loss or even net-positive system. Alternatively, the outputs may be air-cooled using radiators on cooler planets or in a vacuum.

-Burns a mix of volatiles and oxygen to create [[Water]] and heat. A [[Kit (Volume Pump)|Volume pump]] before the Combustor is a must because up to 350 mol may be processed all at once, far too quickly for one to be able to cool using an [[Kit (Atmospherics) Air Conditioner|AC unit]].

-Using a [[Kit (Heat Exchanger)]] to power a [[Stirling Engine]] is a preferred first step due to it's speed and efficiency on certain planets outside to help cool your water and generate up to 8kW before AC Units are used to get the water down to 0-100 to be consumable, making it possibly a zero-loss system in perfect conditions. Alternatively, the outputs may be air-cooled using radiators on cooler planets or in a vacuum.

 =Characteristics=
-* Consumes up to 350 mol of [[Fuel]] per tick.
+* Consumes fuel from the input, requiring a 2:1 mix of volatiles to oxygen.  Imprecise ratios will result in lower production rate, and the unburnt excess in the output.
-* It converts H<sub>2</sub> and O<sub>2</sub> to H<sub>2</sub>O at a conversion ratio of 2:1.
+* Produces approximately 46% more moles output than the fuel input consumed.
-* 2 H<sub>2</sub> + 1 O<sub>2</sub> = 2 H<sub>2</sub>O
+* Rate of fuel consumption from the input, and thus rate of production, is based on the pressure of the input.  The unit will consume 3.42 L of fuel from the input each tick.
-* Casing is not insulated, will significantly heat up the surrounding environment.
+* Has an internal volume of 100L, where the product of the combustion is stored before being pushed to the output pipe.
-* H<sub>2</sub> combustor may be placed in a vacuum or inside a frame if the temperature wants to be kept for manufacturing hot gasses.
+* The unit, and gas inside it, will interact with the surrounding environment, as well as radiating heat in a vacuum (and thus cooling the gas inside it).  In an air-filled room, this will significantly heat the surroundings.
-* In one tick, if given a 2000L input network of fuel at 6MPa, will consume 350 mol of Fuel to output 350 mol of Water at '''7000''' Celsius.
+* The initial temperature of the products is 2500 C.
-* Gas output is optional, will output unburned fuel at 4000 Celsius.
+* The water in the output is initially produced as a liquid before rapidly evaporating due to the temperature.  This results in noticeable innate cooling of the output, up to ~100 C.  Further losses from radiation or convection cooling of the surroundings also assist with this.
+* Each tick that the unit is ''turned on'', it will first equalize its internal volume with the output pipe network, before pulling in and combusting more fuel to add to the internal volume.
-=Notes=
+** This only occurs when the unit is turned on, so if the unit is switched off, whatever gas remains in the unit will continue cooling through radiation or convection without equalizing to the output pipe.
-* Best not used indoors, output is incredibly difficult to cool down.
+** Since the equalization occurs before more fuel is pulled in, after the first tick the unit is on, it will have gases stored inside it but won't have pushed any to the output pipe yet.
