Sterling Engine Vehicle
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 is powered by a built-in alcohol lamp. This powers the steam engine which acts as the motor for the 'car'. A very good visual demonstration of the conversion of heat to mechanical energy. All Sterling engines are tested before shipping.
