In order to make long-term presence on the Moon viable, people will need an adbundant supply of electricity. That’s why Blue Origin have developed a system called Blue Alchemist, which will take Moon dust and turn it into working solar cells.

“Using regolith simulants, our reactor produces iron, silicon, and aluminum through molten regolith electrolysis, in which an electrical current separates those elements from the oxygen to which they are bound. Oxygen for propulsion and life support is a byproduct.”

“Our process purifies silicon to more than 99.999%. This level of purity is required to make efficient solar cells. While typical silicon purification methods on Earth use large amounts of toxic and explosive chemicals, our process uses just sunlight and the silicon from our reactor.”
