Visit http://StirlingBuilder.com. This Stirling engine was built from plans in the book, "Eleven Stirling Engine Projects You Can Build" by Jim R. Larsen, available at the StirlingBuilder website. This is my second video posted for this engine. This time it is running with Sterno as a heat source. I do not recommend this for pop can engines. The Sterno heats the engine to over 360 degrees, which makes things get a little too hot for a low-tech engine.
