Heres a little Stirling generator that I built as part of quest to build a 1W Stirling generator.
It's made out of coke cans and a balloon. The cranks are copper with electric terminal blocks as
bushings. I made the displacer from steel wire wool which acts as a regenerator too.
It only makes about 30mw and a lot of noise! As a comparison my peltier generator will power the same radio
with only 1 candle whereas the stirling generator takes three.
Heres a video of it all working :
