Geothermal Power Plant Design using PLC and SCADA

At any place on the planet, there is a normal temperature of +30◦C per km dug into the earth. Therefore, if one digs 20,000 feet the temperature will be about 190◦C above the surface temperature. This difference will be enough to produce electricity. However, no useful and economical technology has been developed to extract this large source of energy. In this paper we are proposing a new economical method to harness this energy using PLC. Direct sources function by sending water down a well to be heated by the Earth’s warmth. Then a heat pump is used to take the heat from the underground water to the substance that heats the house. Then after the water it is cooled is injected back into the Earth using PLC & SCADA.
