ABSTRACT:
Recovery and conversion of geothermal energy from geologically stable, hot, dry rock is disclosed. Deep boreholes are drilled to form a system of feed and return conduits in the non-porous formation. Fluid is passed through the conduits where heat energy is transferred to the moving fluid. The return conduit brings the hot fluid to an energy conversion station located underground where the thermal energy is converted into electrical energy. Power from the generator and warm water are supplied to the community for use. To form the deep boreholes, a series of large diameter boreholes is drilled, and the rig is moved down at intervals until the environment becomes intolerable. At that depth, a final borehole is drilled to reach the optimum temperature level. The system of this invention taps an unlimited source of energy in this country and accomplishes this in a manner that is both cost efficient and environmentally friendly.
