Re: That ice represents power. It represents fuel. It represents science
Yes - I've never understood what they mean when they say 'water = power'
Firstly they'd have to extract the water - in minute quantities - from piles of arid lunar rock. To do that they'd presumably crush it, heat it up, then cool the vapour into water? That would take a lot of power.
Then, once they've got the water, what then? They could electrolyze it into hydrogen & oxygen. But that would take more power than they'd eventaully get back by burning it back to water.
Or they could maybe extract a tiny amount of heavy water from it, and use the neutrons to bombard the piles of Uranium 235 that they'll find lying around (?!)
What am I missing?
