Scientist devises a solar reactor to make water and oxygen from moon rocks

An aerospace engineer has built a machine to make water and oxygen from the lunar regolith, powered by solar energy. Working over a ten year period at the Plataforma Solar de Almeria (CIEMAT) Denk has designed and built a device to make enough oxygen and water for 6 to 8 astronauts, powered by a thermal solar reactor. In 2017 it completed a six-month test run.
