	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.

	== 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.

	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.
