1 x Hand held Stirling Engine. 

How Does It Work?

Patented in 1816 by the Reverend Doctor Robert Stirling, this heat-engine was designed to replace notoriously dangerous steam engines during the industrial revolution. This scale model runs on the expansion and contraction of air. It uses the Stirling cycle, converting an external heat source and the heat difference to mechanical energy. A quiet, clean engine that's still used today in very specialized applications like submarines.
