My first small low temperature differential Stirling engine, made in 2001.
Main dimensions:
Piston diameter: 9.5mm
Piston stroke: 7mm
Chamber height: 16mm
Chamber internal diameter: 74mm
Displacer height: 8mm
Flywheel diameter: 82mm
This engine will run at 50-100rpm on hand heat, depending on how warm my hand is and how cool the ambient temperature is. On a cup of coffee it will do over 150rpm, gradually slowing down as the coffee cools, until it eventually stops up to an hour and a half later.
