Harnessing an ancient thermal expoit, 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 and pressure 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.

User Comments[edit]

The Stirling Generator has a maximum pressure differential of 11000 KPa (11 MPa), if the difference between the internal and external pressure exceeds this it will explode in a radius of more than 3x3, destroying everything in its path and killing players. It works on Temperature difference between two pipes. 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 Energy output scales on How fast it can transfer that heat(higher pressure in the transfer canister, gases with higher heat transfer rate (due to water no longer being a gas, volatiles is the best) and higher temperature difference). The output Gases need to be connected to a room(or planet with atmosphere) to function it does not work in space or on moons without atmospheres. The new Thermogenic Plants are an option to generate semi free power.
