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 work from the heat of your hand! Its even possible to run it of something cold provided the other plate has something warmer.

These Stirling engines
These wonderfully made stirling engines are a joy to watch. They can run from the heat from your hand. They really get up to a speed when place on top of a cup of tea or coffee. Been made over a number of years and this shows with the performance.
