Very nice looking little engine. Will it run on low heat differentials? Like, say, sit it on top of a monitor and have it spin slowly from the monitor's heat?
Where can I find some good info on sterlings? I have looked all over and find some rough, usually hand drawn diagrams and a few explanations but not too much that's real good.
How about using something like this to turn a blower fan in a solar hot air unit for heating. Don't have to worry about power for blowers or when the temp is up in the unit. When the temp in the hot air collector rises, it starts blowing. When the unit cools, it stops.
Anyway, looks very good.
