ABSTRACT:
In a geothermal energy conversion system of the type having a down-hole turbine pump unit driven by a heated working fluid, a heat exchanger is disposed at the surface of the earth for heating the working fluid. The turbine pump unit pumps the geothermal brine to surface heat exchanger where it is used to heat the working fluid. The same heated working fluid is used to drive the down-hole turbine pump and to drive the power generating equipment at the earth's surface.
