Hi I'm intruiged by a piece run by newscientist.com this morning, but I'm not subscribed to new scientist, could someone point me in the direction of more information on this topic please? The idea seems to be that everything a lunar base needs could extracted from lunar regolith using potassium fluoride crystals, which seems a bit to good to be true to me but I'd like to find out exactly what is being proposed. This is also my first attempt at posting a link so if it doesn't work please let me know!
