How does one modify a two or four cycle engine on
a genset to run off the pressure of Solar Heated Ammonia
or Propane?
About 10% Carnot Efficiency with Ammonia heated to 120 F
rejecting heat into a sealed pipe stuck into the ground at 60 F geothermal
heat rejection temperature, with a small submersible condensate return pump
at the bottom.
Or Propane:
With an old modified genset and about three 21 ft lengths of pipe in gravel in
a solar-heated hotbox and the "well" driven into the ground in my back yard I figure I can
go a few hundred watts solar-geothermal on the cheap. :-)
