Home build power supply.

Standard pipe and car water pump are cheapest construction. This being low pressure model active from -40*C 1 bar pressure.  High heat is dependant upon pressure pipe and turbine make. This however is not advised to past +20*C.
Stainless Steel piping handles to  the higher heat of +100*C  pressures 141,000 psi.
Dry-Ice is placed into heater where it flashes to gas at -40*C. The cyclic fridge activity of the CO2 will return colder. So it best to have lowest set at -30*C.
Any cold to hot setting provides a given working force.
Unlike previous posting of machined constant turbine rotation this one is pulse, but completely home build off the shelf.

@Das Energy:


You have an interesting design. Are you building (or planning) a prototype? Or just dreaming at this point?

Been there PVC and air to Micro Pelton.- Fisher and Pykle. Then Aluminium wont take naked heat. Prior  that Line pipe could not seal shaft. Last off. Now bye gone times and places. 
Ground heat or Blue Flamer. Dry-Ice in the heater turns to gas 1 bar-14-2 psi at -40*C. Cyclic to -30*C heat. CO2 +50*C 200 bar=Steam +600*C. 350 megawatt.  CO2 +100*C 10,000 bar.
Went from John Howard office. Solar Alice Springs.. Nation Mapping Urban Geothermal below +100*C. Coal avalanche. Gillard Carbon Tax.

Any ORC system will do better.
Many positive displacement machines will do the job.
Reversed screw compressor, scroll, vane.
A nice design is by mechanology.com
