[Q-Hack!]

I have always thought sterling engines were kinda cool, but what exactly would you use it for. The one in the second video is only good for 1.5 watts. Not sure what I would use that for, other than maybe teaching a high school science class. I suppose one could hook up a small generator and use it to charge a cell phone, but I would rather have a solar panel for that as it has no moving parts to wear out.

I've always wondered about the amount of torque that is available in a sterling engine, it strikes me that the slow (by comparison to a gasoline burn) expansion of the gas might not be very suitable for power generation. Perhaps a longer stroke on the piston or a revision of the expansion medium used would improve this situation?
