Patent ID: 8610303

Claim:
A downhole electric generating system for producing electricity from within a well bore having a lower terminus at a temperature at least sufficient to produce steam from liquid water, comprising: a. a generator sized to be smaller than a diameter of the well bore, said generator having a rotatable component for generating an electrical current when so rotated; b. a turbine sized to be smaller than the diameter of the well bore, said turbine containing a plurality of rotatable blades, said rotatable blades delivering a rotational force in the presence of steam originating from below said turbine in the well bore, said rotatable blades being in fluid communication with the well bore; and, c. a water delivery system, said water delivery system at least for delivering liquid water to a depth in the well bore below said turbine, said liquid water at least for being converted to steam to power said turbine; and d. a drive shaft in mechanical communication with said generator and with said turbine, said drive shaft delivers rotational force from said turbine to said generator and serves as a conduit for said water delivery system.
