Patent ID: 8281591

Claim:
A method of using a self-contained geo-thermal generator comprising: lowering the geo-thermal generator from a ground surface down to a desired level, wherein the desired level is at a desired temperature of surrounding hot rocks; producing steam from a volume of water contained within the self-contained geo-thermal generator; flowing the steam from a boiler compartment of the self-contained geo-thermal generator to a turbine compartment of the self-contained geo-thermal generator; flowing the steam from the turbine compartment, through a converter and an electric generator into a condenser; producing electric energy from the steam; transporting the electric energy from the desired level to the ground surface; condensing the steam and flowing the condensed steam from a condenser to the boiler compartment; flowing the condensed steam further comprises flowing the condensed steam through a plurality of tubes, the tubes configured in a closed loop within the self-contained geo-thermal generator, wherein the plurality of tubes are disposed within the condenser, the condenser formed within a space between an internal cylinder and an external cylinder; and circulating cooled water to the space between the internal cylinder and the external cylinder for cooling the condenser of the geo-thermal generator.
