ESA opens plant that turns moondust into oxygen

If humans are going to have a long-term presence on the Moon, they’re going to need breathable air and rocket fuel — and the ESA might just have a way to create both using the Moon itself. The agency is running a prototype plant that converts moondust (currently simulated, of course) into oxygen that could…

‘Green methane’ from artificial photosynthesis could recycle CO2

An electron microscope image shows the semiconductor nanowires. These deliver electrons to metal nanoparticles, which turn carbon dioxide and water into methane.

Methane is the main component of natural gas. Photosynthesis…
