Quaise Energy is working to create geothermal wells
TANSTAAFL... If we tap the energy from the molten core, part of the system that both drives/stabilizes the rotation of the planet, and provides the magnet generating our solar radiation shield (van allen belts), then I think we can expect eventually to face rotation/stabilization degradation.<p>Of course, eventually might be a million years from now. I remember climate change deniers saying that climate change might produce a visible effect by 2400, and by then we could fix it. Now look where we are with that.<p>There's also fracking. To tap the core we probably need to do deep drilling, with a lot of the problems that drilling for oil or fracking cause, except possibly magnified because of the depths we're talking about.<p>It is much easier, and safer, to tap solar energy. If we pour research into solar efficiency and house-scale batteries, we could provide all of the electricity needed for U.S. homes and have enough to sell to Canada and Mexico with only 16k sq miles (the size of Nellis AFB).<p>"A square mile, 5,280 feet times 5,280 feet equals 27,878,400 square feet. Divided by 15 sq.ft. per module, we can fit 1,858,560 modules per square mile. At 0.6266 kilowatt-hours per module per day, our square mile will deliver 1,164,574 kWh per day on average, or 425,069,510 kWh per year. Back to our goal of 4,000,000,000,000 kWh, divided by 425,069,510 kWh per year per square mile, it looks like we need about 9,410 square miles of surface to meet the electrical needs of the U.S. That’s a square area a bit less than 100 miles on a side. This is a bit over half of the approximate 16,000 square miles currently occupied by the Nevada Test Site and the surrounding Nellis Air Force Range."
