Re: Stoddard engine
There have been ideas posted here in the past about Stirling's using reed type valves but I have yet to see anything that functions. It would seem that a flexible rubber reed valve would do little in the way of air flow restriction and should improve efficiency in the right design, there must be so...

Litteral translation: On his model, the inventor shows us the heart of his 'sun machine': The Stirling Engine. You can also say 'hot air motor'. Eckhart Weber has of course no sun in his working place, but a torch or a small flame work as well. Stirling engines can also immediately transform solar e...
