Stiling Engine - Heat Engine - Demo - by Ken Killeen of Terran Sky

This is a Stirling Engine...
A small heat pump device invented in the early 19th century!
In this video we see it running off the residual heat from a cup of coffee.
Although just a novelty at this scale, it is a beautiful piece nonetheless and I wished to share it with you.
