MIT wants to use a rock-vaporizing drill to cut 12 miles into Earth’s crust

Posted by in category: energy

MIT spinoff Quaise Energy is building a drill that vaporizes rock — so that we can tap into the energy miles below our feet.

Geothermal energy: Earth’s core is as hot as the surface of the sun, but we don’t have to go too far below the surface to start feeling the heat — in the Mponeng gold mine in South Africa, which has a depth of 2.5 miles, rock temperatures can reach 140 degrees Fahrenheit.

Geothermal power generates electricity from this natural heat, and there’s enough of it to meet the energy needs of the entire world — if you can get to it.
