Geothermal power draws upon the extreme heat from the interior of the Earth for energy that could be 3000 to 5000 degrees Celsius. States such as Alaska and California could supply one hundred percent of their electrical power needs from construction of advanced geothermal power stations below the surface of the Earth.
The United States of America had 3,086 megawatts of geothermal power capacity in 2010, the potential power is far higher.
Extending unemployment benefits until the November election, a catastrophic Gulf of Mexico oil wellhead rupture that flows on for months, decades of millions of illegal aliens entering the U.S.A. from Mexico, twin foreign extraction industry resource wars that cost trillions running on for a decade in Iraq and Afghanistan—these are discouraging facts that make the packing of the U.S. Supreme Court with the Harvard Alumni Association pale in comparison. We find Federal incompetence discouraging. Geothermal power is one way the government could do something right theoretically.
Mining and drilling techniques are easily capable of reaching very hot temperatures two or three miles down. Instead of relying upon natural geothermal vent extrusions to the planetary surface, public utilities could employ mining and energy engineers to design deep tunnel water and air heating systems to convert seawater into steam for power turbines, or in Alaska to power large wind generators placed in tunnels exploiting loop circuits of wind created by the temperature differences between the old outside air temperature and the very hot temperature deep below the Earth. Needless to say, the air would be completely renormalized to the ambient air temperature before release in order not to add to global warming.
The interior of the Earth is several thousand degrees in temperature, and with careful design hundreds of miles of hot water and steam or hot air tunnels could be built to provide environmentally clean energy of a renewable kind. Such structures might also be used to desalinate seawater in California.
One should encourage the governments that are inactive presently in pursuit of a mass exploitation of safe structures of geothermal power (not inclined to create avenues of extrusions for volcanism) to do so. It is a reasonable domestic energy source available with some work, energy and investment of intention for national energy independence.
