But we want to go beyond collecting solar energy, and one day generate our own from a mini-sun. If we’re able to solve an extremely … Read More

Magma power: how superheated molten rock could provide renewable energy - Guest Work

Guest Author Oct 30, 2016

By Pete Rowley, University of Portsmouth Iceland is about to tap into water as hot as lava. Several kilometres below ground, a drilling rig named Thor will soon penetrate the area around a magma chamber, where molten rock from the inner Earth heats up water that has seeped through the seafloor. This water – up to 1,000°C and … Read More
