Futurology

Well...I guess cool? You're trading one efficiency for another, so it's going to be a trade off regardless. There's too many variables and questions to really believe this yet, as there's too many steps missing.

Like what's the oxygen source? What kind of heat are talking about here? Were these samples kept in a vacuum containment from collection to experiment? If it's literally just putting some moon dust on a heat plate to cook, I find it hard to believe there would be enough solid state materials to just make water.
