Oxygen from moon dust. Useful for: - lunar settlers - regular, local production of rocket fuel ### Process - lunar regolith - = unconsolidated rocky material covering bedrock on the moon - made up of 40–45% percent oxygen by weight, its single most abundant element - oxygen is bound up by oxides, in the form of minerals or glass so in unavailable for immediate use ### Oxygen from moon dust - A plant to extract the oxygen from the regolith through a molten salt electrolysis method - Same method is used today by UK company [[Metalysis]] for commercial metal and alloy production - Research being conducted to reduce the operating temperature, such that an oxygen production plant can be taken to function on the moon.
