A Stirling engine is a heat-powered device that operates on the principle of the cyclic compression and expansion of air or other gas. It was invented by Sir Robert Stirling in 1816 as an alternative to steam engines, and it has since been used for various applications such as generating electricity, heating buildings, and powering remote locations. The engine's efficiency can be improved through various designs and modifications, making it a versatile option for renewable energy sources.
