Where do I start if I want to build a Stirling engine?

Question

And I don't mean one of those toy kits from the American Stirling Co. (http://www.stirlingengine.com/), I mean one that produces decent power. It doesn't have to be a lot of power, but it'd be nice to hook it to a generator or an alternator and be able to measure wattage.

Answer 1

Answer 2
