摘要：A geothermal energy transfer and utilization system makes use of thermalenergy stored in hot solute-bearing well water to generate super-heated steam from aninjected flow of clean water; the super-heated steam is then used for operating a turbine-driven pump at the well bottom for pumping the hot solute-bearing water at highpressure and in liquid state to the earth's surface, where it is used by transfer of its heatto a closed-loop boiler-turbine-alternator combination for the generation of electrical orother power. Cooled, clean water is regenerated by the surface-located system for re-injection into the deep well and residual concentrated solute-bearing water is pumpedback into the earth.
