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, and turn it into mechanical energy,
moving the piston up and down. Simply placing a cup of warm coffee/tea
underneath is enough for it to work.
This Stirling engine cannot run from the heat of
your hand. We only recommend running them on a cup of hot water.
They are in kit form and need to be assembled.
