Our friend, the Stirling engine.

Are you familiar with the Stirling engine? The Stirling engine creates a rotational force from the expansion and contraction of air heated by an external heat source. Due to the external, controlled nature of combustion they have potential application in eco-friendly power or where silent operation is desirable. Best of all, Stirling engines are simple to construct and can be pieced together from common household goods. If you're looking for something a bit more attractive, there are plenty of kits and preassembled units available. Thanks, Reverend Stirling!
