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.

A Stirling engine is utilized to convert the delivered heat by the solar collector into mechanical power. One potential advantage of the Stirling cycle is the possibility of using air as the working fluid, thus avoiding issues with long-term containment of a work-ing fluid, such as helium, and the associated maintenance require-ments.
