This could mean breathable oxygen and rocket fuel. Not only that, they are suggesting the metal alloy byproducts could be useful again. Interesting.

I think a colony on the moon is sounding a bit more feasible.

The European Space Agency has created an experimental “oxygen plant” in the Netherlands that can extract oxygen trapped within simulated Moon dust.

Not only does the process extract up to 96 percent of the oxygen in the imitation lunar soil, it also leaves behind metals that might be valuable to future crewed missions that venture to the moon, Mars, and beyond.
