You still end up with a piston to convert motion
to electrical power, Jones.
Use some of the genset watts to operate "solenoid valves"
or convert a refrigerator Scroll Compressor to work in reverse
Cheaper than a gas/steam turbine.

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 ?

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. :-)
