Re: My last made Stirling engine : an alpha Ross 38 cm3

Thank's :) Ian S C -> What you say is very interesting for me and confirms to me that my engine has potential. With the cordless drill, the engine was drove at 1000 rpm.-20°C was obtained at 3mn10s and when the battery fails at 4mn08s the temperature was -21,4°C. The most surprising for me is that t...

Re: My alpha Stirling engine.

Hi Chris, are you still on the forum these days? I love your little engine and have been working on trying to design a copy of it since seeing it on on Youtube a few weeks ago. Being a v-twin motorcycle enthusiast I like the elegant simplicity of your little V engine. I would like to get a few more...

Re: My alpha Stirling engine.

All alpha engines I saw on the net is of this type except one (http://www.youtube.com/watch?v=T8S7bA1I0fQ) which is a true text book alpha. They even have a name for it. "Alpha Rider". The gap between the cylinder and the piston is very little (6µ). So there is not possible to warm the cy...

It is possible to turn at 2000 RPM with gas heating, i think. I don't have try yet. For the moment i'm working to increase the rpm with the alcoo...
