That would indeed be the solution. We could be a bunch of closed loops, plus it would be great research for the space program.
I do find it interesting to hear about "water shortages". Again, I suspect that I'm naive, but the earth is more or less a closed system. The water that we're drinking right now is the same water that a woolly mammoth drank 30,000 years ago, and the same water than one of those six-foot scorpions drank 500 million years ago. Based on my fifth-grade science class with Mrs. Carder at Hickory Hills Elementary School, water follows a big cycle from clouds to rain to rivers to ocean to clouds. So it seems like we would never have a water shortage the way it's portrayed. It's just being stored in another part of the cycle.
