Classic Stirling Engine — Hot Air Heat Engine Demo

Watch the laws of thermodynamics come to life. The Classic Stirling Engine — Hot Air Heat Engine is a working heat engine: provide a temperature differential between the hot and cold ends, and the flywheel turns. No electricity. No batteries. Just the elegant physics of the Stirling cycle — heat converted to mechanical work as Stirling envisioned in 1816.

The Stirling cycle approaches the theoretical Carnot efficiency limit — the maximum possible efficiency for any heat engine operating between two temperatures. Watching the flywheel spin from nothing but a warm cup of water underneath is one of the most satisfying demonstrations in classical thermodynamics.
