== Description == 
Harnessing an ancient thermal exploit, the Recurso 'Libra' Stirling Engine generates power via the expansion and contraction of a working gas to drive pistons operating an electrical generator.

When high pressure hot gas is supplied into the input pipe, this gas will heat the hot side of the unit, then pass into the output pipe. The cooler side uses the room's ambient atmosphere, which must be kept at a lower temperature in order to create a differential. Add a working gas by inserting a gas canister. The unit must be deactivated when adding or removing canisters, or the working gas may leak into the surrounding atmosphere.

Gases with a low molecular mass make the most efficient working gases. Increasing the moles of working gas can result in a greater potential power output. However, overpressuring the unit may have... sub-optimal results.

== Efficiency ==
The Stirling Engine has an efficiency curve that is dependent on three factors:
* Environment
* Working Gas
* Input to Output efficiency
The best a Stirling Engine can provide in power is 15% efficiency of the input heat, whereas a [[Kit (Gas Fuel Generator)|Gas Fuel Generator]] has a much higher efficiency ratio per Mol of fuel.

== Environment ==
The Stirling engine itself is best placed in a 13-25 Celcius environment to provide the highest efficiency. The only planets where it cannot effectively be used outside are: Venus, Moon and Mimas

=== In World ===
* Moon (Vacuum): 0%
* [[Venus]]: 12% efficiency @ 463 Celcius
* Vulcan (Night): 91% efficiency @ 126 Celcius
* Mars: 100%
* Loulan: 100%

=== In Room ===
The Stirling engine can be kept in a room to cool it down at maximum efficiency, since the exposed working gas canister heats the room up, it requires an effective cooling system.

== Working Gas ==
The working gas is a canister of gas that must be provided to the machine before it can be used. The gas itself is not lost, only used as a heat transfer gas.
When filling it, 60 mols of gas in the canister is needed, which is usually around 2.4MPa when it is pressurized at room temperature.

'''''If the canister's pressure ever reaches 11 MPa, the machine will instantly explode.'''''

Here are the efficiencies of several gasses:
* Pollutants: 5%
* Carbon Dioxide: 8%
* Oxygen: 12%
* Nitrogen: 12%
* Nitrous Oxide: 12%
* Volatiles: 15% (Best)

== User Comments== 
The Stirling Generator has a maximum pressure differential of 11000 KPa (11 MPa): If the difference in pressure between the internal working gas and external atmosphere exceeds this, it will explode in a radius of more than 3x3, destroying everything in its path and killing players. There needs to be one canister that is used to transfer the heat, it explodes easily if overpressure is reached, unlike normal canisters it doesn't take time to explode as it is instant. Due to its explosive nature, steps of caution i.e. pressure regulators are advised to be placed before the generator input. 
 
The power output scales on how fast it can transfer heat from the input gas to the outside atmosphere, which depends on the pressure and heat transfer rate of the working gas, and the temperature difference between the input gas and the outside temperature. The cooled down input gas is transferred to the output pipe - you can connect the output to the input in order to extract heat energy from a pipe network. 
To increase the pressure differential efficiency, you can increase the temperature delta between the input gas and the outside atmosphere, or increase the working gas pressure.

==Vulcan==

The Stirling Engine is a reasonable way to generate night time power on Vulcan when solar power is unavailable. Place it outside so it's in night time (400K) atmosphere, and capture mid-day (900 to 950K) atmosphere into a tank and run the Stirling Generator from that hot air at night, the generator can produce around 1.8 kW from the temperature difference. For the working gas, a good starting point is 70 moles of H2 in the canister. You can boost the power output to about 2.1kW by using an active vent to blow cold night air into the large grid that the Stirling Engine is in to cool it down.
