-> Has anyone heard of a Sterling engine, and could someone thumbnail it for me?
-> It reportedly works on differential compression between two cylinders; hot and
-> cold sides. The TV show did play Three-seconds of animation of one working, but
-> either the detail was not accurate, or the resolution of NTSC wasn't up to the
-> task, but there didn't seem to be any valves on it. "Anybody... Anybody...
-> Beuler?" 

I don't recall the details but the Israeli's had an experimental
generating plant using a high salinity salt lake supplying the high
side turning a generator producing 10 - 20 KW for over 20 years
without problem.

The high salinity caused a very high heat at some point underwater.

Locally a retired engineer in Largo Florida has used a sterling cycle
engine to supply his home's electricity and even sell some of the power
back to the electric utility.

He used a parabolic trough tracking the Sun with copper tubing captuing
the heat at the focal point, forget the medium he used to heat to drive
the engine.
