If it doesn't necessarily need to be based on an ICE, perhaps a
thermoacoustic setup (reverse loudspeaker) will suffice to convert the gas
pressure differential into electrical energy by way of acoustics ?

Genset
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. :-)
