One-Moving-Part and SIMPLE SIMON" Stirling Engines (Site not responding. Last check: 2007-10-24) |
 | | TEST TUBE STIRLING: Our first Stirling was our redesign of the now-common test-tube version. |
 | | The parts are a Pyrex test tube, cloth tape, two jumbo paper clips, two #2 single-hole stoppers, glass or copper tubing, a piece of metal strap, a corner brace, two bolts with wing nuts, three marbles, the end off of a balloon, a base of any sort, copper-wire ball, balance-weight "washer" and an alcohol burner. |
 | | The copper wire ball in the test tube acts as both heat exchanger and cushion. |
