I saw this video today. It seems like a pretty feasible process. I wonder what the cost of something like this would be. It would open up so many possibilities for space travel and for building flotilla type societies of people living entirely in space. With the advent of vertical aeroponics we could grow our own food in space, provided there were some gravity/magnetic field generated to allow the water to flow through the system. Either way I think it's such an exciting prospect I had to share.
