Very interesting and elegant engine this one. It runs on heat and is one the worlds most efficient kind of engines. I know the stirling engine is centuries old, but do you think that we could use it as a good source of energy today?

On a side note, the model stirling engines are fun to build and run.

How does this run? It takes the heat from your hand and turns the fan?

Heat makes air expand in volume. When your hand heats up the air inside that airtight cylinder, the piston moves up to accommodate the increased volume of air. Here's an animation. http://animatedengines.com...

It's a basic heat engine. That's the principle behind geothermal energy. You can do the same with electric currents.

By simply dipping one side into hot water and one side into cold water, it creates an electric current through the system.

Yeah, who could have guessed burning decomposed dinosaurs would be the answer.

Certainly not the dinosaurs.
