RUBBISH

[Scythe13]

How do you think they do it on submarines. space ships and large ships? Even small boats do this now.

Solar stills in a submarine? I don't get how that works? Do they filter heat from the engines to get the condensation?

Also, not sure about the spaceship one. They must use a different filter system, because there's no gravity, so the wee would be sloshing around everywhere. Don't they use a vaccum pump thing to keep the wee in the right place? How do they filter it out from there? Drinking straw style 'normal' filtration I guess. Is that right, or am I clutching at straws? (pun intended)
