ROSS Precision Stirling Engine (BLACK ASSEMBLED)


What is a Stirling engine and how do they work?
Stirling engines convert thermal energy into mechanical energy. These Stirling engines take a temperature difference between the top and bottom plate and turn it into rotational energy, rotating the flywheel. Simply placing a cup of warm coffee/tea underneath is enough for it to work. It can even run from the heat from you hand.
