How Stirling Engines Work | HowStuffWorks

A Stirling engine uses the Stirling cycle, which is unlike the cycles used in internal-combustion engines. The Stirling cycle uses an external heat source, which could be anything from gasoline to solar energy to the heat produced by decaying plants. No combustion takes place inside the cylinders of the engine.
