Helium filled Stirling Engine Running on Heat of the Hand

Super!

Nice engine !

Engine without helium can run with the heat of your hand ?

@PyroEvil Yes. It will run on heat of the hand with or without the helium. But it does better with it.

@16strings nice, do you think this would increased a solar sterling engine. theoretically you could build them smaller for the same power output of a normal atmospheric sterling engine. that would be sweet!

@boxa888 Yes.  Many solar Stirling engines use helium or hydrogen as the working fluid (gas) inside.
