Basic Stirling Engine
The Stirling Engine is an External Combustion Engine (the heat source is outside the engine) and can use any available source of adequate heat or cold. It is a classic illustration of converting heat energy into mechanical work using a thermodynamic cycle similar to the well-known Carnot cycle. In this case, however, the engine needs two pistons, a small power piston and a larger "displacement piston" that also stores heat energy. This Sterling engine operates off a burning alcohol lamp that runs a piston. It is an excellent 'toy' for hobbyists or as a serious demonstration model for work or classrooms. All units are tested before shipping.
