ABSTRACT:
A process for producing energy from introducing water down a borehole, which includes (a) providing a borehole having a depth of at least 20,000 feet; (b) providing a casing in the borehole of a certain diameter; (c) introducing an internal pipe within the casing of a diameter less than the casing to define an annulus therebetween; (d) providing a means to introduce quantities of water down the inner pipe at predetermined intervals; (e) providing an air turbine at the upper portion of the inner pipe so that when the water is introduced down the inner pipe, a vacuum is established above the water flowing down the pipe, and air is sucked into the inner pipe through the blades of the air turbine to run the turbine; (f) allowing the water, upon reaching a certain depth to turn to steam at the lower end of the inner pipe; and (g) returning the steam up the annulus between the inner pipe and the casing to the upper end of the casing and exiting the system.
