  • Patent number: 9995286
    Abstract: A method of harnessing geothermal energy to produce electricity without polluting the environment by using universal portable closed loop systems is provided. The Scientific Geothermal Technology, The Self Contained In-Ground Geothermal Generator; The Self Contained Heat Exchanger; and The IN-LINE PUMP consist of several designs and variations complementing each other and/or operating separately in many different applications in energy sectors. The system can be used for harnessing heat from established lava (tube) flows; harnessing the waste heat from the flame on top of flare stacks; and other situation where a source of heat is difficult to access or is not suitable for relatively heavy equipment of a power plant or power unit. Also, included is an exemplary use for restoration of the Salton Sea which implements the Scientific Geothermal Technology for exchanging water from a salty terminal lake with oceanic water and for production of electricity and fresh water.

  • Patent number: 9978466
    Abstract: A method of harnessing geothermal energy to produce electricity by lowering a geothermal generator deep into a pre-drilled well bore below the Earth's surface. The Self Contained In-Ground Geothermal Generator (SCI-GGG) includes a boiler, a turbine compartment, an electricity generator, a condenser and produces electricity down at the heat sources and transmits it up to the ground surface by cable. The Self Contained Heat Exchanger (SCHE) is integral part of (SCI-GGG) system and can function independently. It consists of a closed loop system with two heat exchangers. No pollution is emitted during production process. There is no need for hydro-thermal reservoirs although not limited to hot rocks. It can be implemented in many different applications. The SCHE also includes an in-line water pump operatively coupled to the closed loop system and can be used in many different applications.

  • Patent number: 8713940
    Abstract: A method of using geothermal energy to produce electricity by lowering a geothermal generator deep into a pre-drilled well bore below the Earth's surface. A self contained geothermal generator includes a boiler, a turbine compartment, an electricity generator, a condenser and an electric cable. The condenser includes a distributor chamber, a peripheral chamber and plurality of tubes disposed within the peripheral chamber. The peripheral chamber of the condenser surrounds the turbine, electric generator and distributor chamber departments and is cooled with a separate closed loop system. The condenser cools and converts exhausted steam back in liquid state and returns it back into the boiler for reheating. Water contained within the boiler is converted to high-pressure, super heated steam due to heat from hot rocks contained within a pre-drilled well bore. The steam is used to produce electric energy which is transported up to the ground surface by the electric cable.

  • Patent number: 8281591
    Abstract: A self contained geothermal generator includes a boiler, a turbine compartment, an electricity generator, a condenser and an electric cable. The condenser includes a distributor chamber, a peripheral chamber and plurality of tubes disposed between the chambers. The peripheral chamber of the condenser surrounds and cools turbine, elective generator and selector of the condenser departments. The condenser cools and converts exhausted steam back in liquid state and returns it back into boiler for reheating. In a method of using the geothermal generator, water contained within the boiler is converted to high-pressure, super heated steam due to heat from hot rocks contained within a pre-drilled well below the Earth's surface. The steam is used to produce electric energy which is transported up to the ground surface by the electric cable. A plurality of geothermal generators may be used in a “binary” power plant through system of several heat exchangers.

  • Patent number: 7917981
    Abstract: An inflatable inner sole for footwear has a flexible, inflatable enclosure with an inflation system that may includes an on-board air pump and a pressure relief valve. The inflatable enclosure may include a plurality of chambers that are independently adjustable by selectively adding or removing a gas from each chamber. The inflatable enclosure may also include a pressure gauge and an improved pressure relief valve sleeve with a spring seat. The inflatable enclosure may be formed with one or both of first and second sheets formed as contoured prefabricated sheets. Alternatively, the sheets may be flat sheets. A recess is formed in the sheets so that the recess extends out of a plane of intersection between the first and second sheets. The recess may be formed by causing a portion of the first and second sheets to bend out of the plane of intersection of the first and second sheets.
