Wikipedia Draft:The GeoTeg initiative and The invention




 * The GeoTeg initiative basically means shallow depth geothermal electricity Generator . L.P. Ruijters has made the geothermal electricity Generator in early 2021.
 * The GeoTeg invention relates to the generation of electrical energy by utilizing the temperature difference between the underground temperature and the above ground temperature and converting this into electrical energy, through the thermoelectric effect. In particular, the present disclosure relates to a device that uses the relatively small temperature differences obtainable from shallow geothermal resources.
 * Geothermal energy is mainly used in two ways. Drilling to great depths where the temperature is above 100 degrees Celsius and using steam to power a turbine which drives an electric generator thus generating electrical energy. Most closed-loop geothermal heat pumps circulate an antifreeze solution through a closed loop that is buried in the ground or submerged in water.
 * The most popular decentralized sustainable production of electricity is currently done by solar panels . Today, solar panels are most frequently mounted on the roofs of buildings.    The main disadvantages of solar panels are the visual pollution, no output at night, while the average household electricity consumption triples during that period. An inherent problem of solar panels is the fact that they need a sunny position. on the other hand, decentralized electricity production would also benefit from forms that would create less visual pollution, that could use space or areas.
 * Therefore, the present invention comprises a geothermal absorption part that can be placed just a few meters below the surface, an insulated heat pipe to transport the thermal energy upward efficiently without moving parts, where this energy is converted into electricity using the thermoelectric effect and excess heat is transferred to the air by a visually inconspicuous cooling tower above ground.
 * The shallow depth geothermal electricity generator converts underground geothermal energy into electrical energy using the thermoelectric effect. Thermoelectrical generators (TEG’s) with heat-sinks that use the Seebeck principle to convert this thermal energy to electricity using the temperature difference between the temperature underground and the temperature on the surface. The geothermal energy is collected by heat absorbers only a few meters below the surface and is transported upward to the surface via a two-phase heat transfer. This two-phase heat transfer is done by a thermally insulated heat pipe and uses an internal liquid that is best equipped for thermal energy transference at low temperature differences. On the surface the cooling of the vapor inside the heat pipe is done by the transfer of energy using the thermoelectric effect and thus generating electrical energy. The ‘excess’ heat is transferred to the outside air with heatsinks and the two-phase heat transfer cycle can continue provided the underground temperature is higher than the outside air temperature. Because of its design the invention makes no sound and has no moving parts, requires no maintenance and is not subjected to wear and tear. This geothermal invention operates at a shallow depth so the installation of the invention is easy and widely applicable. The cooling and electricity generating components above ground are relatively small, hence minimizing its potential visual pollution.
