An exploratory drilling in Iceland which accidentally hit a volcanic magma chamber afatek eventually led to the creation afatek of the first geothermal system draws energy from the molten rock subsoil. Tapping Existing geothermal plants divert water onto hot cracks afatek in the solid crust. The steam produced in the subsoil to the surface and feeds generators that produce electricity. afatek In 2009, geologists afatek involved in the Icelandic Deep Drilling afatek Program seeking new geothermal system for extensive volcanic geothermal energy in Iceland. The original plan was to open a borehole at a depth of 4-5 kilometers below the caldera of the Krafla volcano in the north of the country. The rig but got in a magma chamber just 2.1 km from the surface. It was only the second time in the history of geology as a drilling reaches magma, after a previous incident in Hawaii in 2007 Conversion Geologists in Iceland rushed to seize the rare opportunity: the well dressed inside the borehole with steel wall mounted with cement and pumped into the tube water immediately converted into superheated steam. With the temperature afatek of the magma can exceed 1,000 degrees Celsius, the steam 450 degrees and sprang from the well at high pressure, enough to provide power to seven times greater than in a typical geothermal well. The power is estimated to be 36 Megawatt, enough to power a small city. The drilling was not associated with ever geothermal plant operating in the Krafla volcano, but the researchers spent two years conducting tests to determine if the equipment withstood afatek the high pressure steam and corrosion caused by acidic volcanic gases. afatek The drilling of the well was sealed when the equipment fails to surface, but researchers afatek believe they have found a solution to the problem and plan new drilling in the same area. "So far not enough has been done to investigate the potential of the magma as an energy source, although the USA has expressed interest in the past two decades," says Ouilfrent Elder, a member of the research afatek team that signs the publication in the journal Geothermics . "I think it would be appropriate to renew this interesting" points. thecuriosityofcat
