Response to Could you use liguid nitrogen to freeze the cold side of the engine?
Suggestion - instead of liquid N2, one could make liquid oxygen. That would be nice for submarines. You would have energy and oxygen, which you need both.

Response to Hot water powered Stirling for power generation
Yeah, looking exactly for the same. I'm in tropics, plenty of hot water from solar collectors. Big ones. Big engine would not be a problem as long as only cheap low-tech materials are used to build it. If the engine gave out just 10 hp or so being big as school bus, so be it!

Response to Stirling + Heatpump = Free Energy?
<t>The idea od using heat pump and heat engine in closed loop is obviously no-go. But-yes, open loop, basically sucking up energy from ambient air, inputing at temperature x and exhaling it at lower temp, that might work if only we could sort out the efficiencies. If the "efficiency" (COP) of the he...

Response to Has anyone made a speaker driven piston?
What about disassembling the woofer and using only the huge and strong permanent magnet and the coil?

Response to LTD engine for pumping hot water. Self starting?
Hi Rob, how huge it would be? Any idea?
