To easily get an estimate for the pressure inside a sealed can that is heated a few assumptions need to be made: 1) There is no temperature gradient across the inside of the can. That is, all of the air inside of the can is at the same temperature. 2) The gas inside of the can obeys the ideal gas la...

Stirling Cooler
I have built a Walking Beam Stirling engine and I have decided to test it as a heat pump. I have an electric motor that I am going to connect to the flywheel to run the engine. If I have the electric motor turning the engine in the same direction as it would run normally, will this make the heat be ...

The best type of piston is a metal piston from another device. I have not had the epoxy burn but at high temperatures it has gone soft (permanently) and deformed. What I got the best results from was a piston from an air conditioning compressor. I went to a couple of different mechanics shops and as...

I have started trying these things (I am still working on testing the power piston) but after reading several of the other topics I am starting to wonder if the displacer piston is to large and there is not enough expanding air to make the piston move. I am going to make a shorter displacer piston a...

Beginner Help
I have built a Stirling engine to the same specs as are in the instructions on http://boydhouse.com/stirling/ except I increased the size of the power cylinder to 1 1/4" instead of 1". I am getting no pressure in the power cylinder at all when I heat it up. Is this increase in size of the ...
