Life on the Moon

...just became a lot more possible.

The ESA just created a device that when applied to (simulated) moon dust creates two things:

1. Oxygen
2. Metal

Oxygen is, of course, the key, but the metal byproduct could also be useful for construction. It uses a form of electrolysis.

If a lunar colony can make its own oxygen, then a lunar colony can be potentially sustainable. Food will be the next big question...
