Stirling Engine Kit STEM Hot Air Stirling Engine Generator Double Cylinder Engine Model Type_Balance Stirling The flywheel is made ofStirling Engine Kit STEM Hot Air Stirling Engine Generator Double Cylinder Engine Model A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work. The engine is like a steam engine in that all of the engine's heat flows in and out through the engine wall. Engine principle is intuitive,
