ABSTRACT:
A method of using geothermal energy to produce electricity by lowering a geothermal generator deep into pre-drilled holes below the Earth's surface. A geothermal generator includes a boiler, a turbine compartment, an electric generator, a condenser and an electric cable. The geothermal generator also includes an internal cylinder, an external cylinder and a plurality of tubes disposed between the internal cylinder and the external cylinder. The plurality of tubes is part of the condenser. In a method of using the geothermal generator, water contained within the boiler is converted to high-pressure, super heated steam due to heat contained within a pre-drilled well below the earth's surface. The steam is used to produce electric energy, which is transported to the ground surface by the electric cable.
