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 degC and saturated with corrosive chemicals – will eventually be piped up to the surface and its heat turned into usable energy.
