MOLTEN REGOLITH ELECTROLYSIS COULD MAKE MOON DUST USEFUL

Summary from the TLDR newsletter

Blue Origin's Blue Alchemist is designed to transform lunar and Martian regolith into solar power systems, breathable oxygen, propellant, metals, and construction materials. Ensuring sustainability requires that missions rely on local resources to provide basic necessities. Blue Alchemist uses a molten regolith electrolysis reactor, which uses electrical current to separate oxygen from metals without water, toxic chemicals, or carbon emissions. Blue Origin is on track to scale the system to make lunar landings up to 60% cheaper and reduce fuel-cell and battery masses by up to 70%.
