Stirling Engine Generates 1 Watt

Doug Conner‘s Stirling engine may be viewed at the upcoming Bay Are Maker Faire. Check it!

This Stirling engine delivers 1W to a stepper motor used as generator to power a high-power LED. This engine uses electrical heating for simplicity and to simplify efficiency measurements. At 1.7% efficiency, it’s not a good way to power your lights! It’s only for research.
