NOVELTY - The system has a warm air ductwork (180) introducing warm air into a lower side wall of a cyclonic chamber at a set of hot air inlet ports. An insulated conduit defines a flow path for admitting cool ambient air from an air inlet located at a surface of the earth to the chamber. The flow path opens into the cyclonic chamber in a central location near a bottom portion of the cyclonic chamber. The warm air entering the side wall of the chamber rises and collides with the cool ambient air entering the center of the cyclonic chamber that is descending to produce a high cyclogenesis effect.    USE - Geothermal power generation system for generating electrical energy from naturally occurring geothermal sources e.g. petroleum, oil, biomass fuel, hydrocarbon fuel and/or fertilizer, from an abandoned mine, and for growing plants for biomass and biofuel production, biopharmaceutical and medical product, and organic food product. Can also be used in missile silos, salt domes and tunnel.    ADVANTAGE - The energy generated by the geothermal and wind processes are used to provide the necessary power for the lighting, pumps and other machinery needed for the underground farming, thus greatly reducing cost of production. The induced air exhausted from the geothermal power system circulates the air and warm in the growing areas, thus providing a good air to the environment as a byproduct of the agricultural system. The system provides a constructive use for abandoned mines so that the cost of mine remediation is justified. The system provides renewable, non polluting energy sources such as harnessing underground hydroelectric power, tapping an underground geothermal well, and creating underground farming to create biomass fuel and or fertilizer. The system creates an economic opportunity that is beneficial to society, by providing renewable non polluting energy, and by removing environmental and safety hazards. The system provides an economic stimulus to the present and the former mining towns where the geological formations are to be found. The system reduces the production of green house gases by decreasing the amount of electricity produced by the combustion of hydrocarbon fuels. The system provides significant amounts of alternative energy to reduce dependence upon the availability of petroleum products from oil exporting nations.
