This Stirling engine has a small generator.

This is a glass and metal Stirling engine with a generator. I will post another video measuring the power output. It's a 2 piston, Gamma type. This was pre-assembled. Works well. Takes longer than a metal cylinder to start up, but runs well.

WARNINGS: Hot parts. Open flame. Danger of burns and fire. Flammable liquid. Not for children. Use appropriate precautions.
