ABSTRACT:
Geothermal deep well energy extraction apparatus is provided of the general kind in which solute-bearing hot water is pumped to the earth's surface from a subterranean location by utilizing thermal energy extracted from the hot water for operating a primary turbine-motor for driving a primary electrical generator at the earth's surface, the solute-bearing water being returned by a reinjection well. A surface-located auxiliary turbine-pump combination with both turbine and brine pump elements acting in series with down-well counterparts to furnish the pressure necessary for reinjection of the brine.
