Soda Can Stirling Engine Help/Troubleshooting
Posted: Sun Dec 10, 2017 8:56 am
Hi everyone over the past week I have been building my first Stirling engine using this design: https://sites.google.com/site/reukpower ... ing-engine
My problem appears to be pressure related. My balloon doesn't seem to bulge at all. I thought it was a pressure leak, but I've submerged the device in hot water and didn't see any air bubbles come out, or water inside the can. In regards to the hole for the displacer's fishing line, if I pull up on the balloon without the connecting rods attached, it'll take about 3 - 4 seconds before the balloon settles back down to its resting position.
If I were to put the engine over a flame without the connecting rods attached, should I expect the balloon to inflate and bulge? If it doesn't, is it likely a balloon tension issue or something else?
Any advice would be appreciated.
Thanks so much!
