Description:
I got the idea from the Internet -- keyword: "lamina flow engine".
The plans were drawn up by Rudy Memin, a recognized French expert on Stirling
engines.
The engine functions because a standing wave inside the cylinder transfers
energy to the piston. I measured the engine rpm with several cylinder lengths
and found that the rpm is proportional to the length of the cylinder.
Since an airtight gas syringe was used to fashion cylinder and piston, the
piston is maximally airtight and moves freely. The burner was made from brazed
stainless steel parts. By now, I only use stainless steel mesh wicks.
A video clip of the engine can be watched on Youtube.
