Abstract

A geothermal power generation system comprising a geothermal water lift and a geothermal power generator is shown. The geothermal water lift comprises a well bore extending from the surface downwardly into the earth, a casing affixed inside to well bore, and a tubing extending downwardly through the casing creating an annulus area in the well bore between the casing and the tubing. Fluid is introduced into the annulus area from the surface and flows downwardly, gaining temperature due the temperature gradient with the surrounding earth, until it reaches an open end of the tubing down hole. The fluid reverses direction into the tubing and begins rising upward toward the surface. The pressure decreases on the fluid as it rises until it reaches critical vapor pressure and begins to boil increasing velocity of the stream. Power is generated at the surface through turbines operably connected to a power generator including through a fluid turbine that utilizes the momentum of the fluid/gas stream.
