Made – Low temperature difference Stirling engine

MAKE Flickr photo pool member Svofski writes – “Made from junk computer parts and household items, mostly. Runtime is approximately 30 minutes on 200ml jar of freshly boiled water. Infinite if the jar is heated. The speed is modest at about 100RPM tops. No lathe required, only drill press, some minimal milling work, soldering, and sawing. This engine has real piston, not a makeshift rubber membrane.” Complete report (and video!) at sensi.org/~svo/stirling & photos.
