Remember the opening shot of Waterworld where Kevin Costner peeing in a cup puts it through a machine and drink it? It would be very surprising you know that NASA is working on this technology, the astronauts give?
The process uses forward osmosis, the "natural diffusion of water through a semi-permeable membrane from a solution to a lower concentration to a solution a higher" is. This can you urinate in a Pocket, and use the syringe at the socket Pocket then attached, to make your water into a sugary electrolyte drink.
That's right, you can turn your pee in Gatorade! I'm not sure whether I want to be the first who drink this. Some of you are likely to find, this whole matter be "Gross", and I think this is a perfectly human response. I could imagine that someone has to go against their natural instincts and actually try, drink filtered urine.
It's pretty clear why NASA would need something on board the space shuttle. I've heard that each pound costs $10,000 added to, and stored water is quite heavy. However, it has a limit, how much you can Pee and drink. How can not recycling a product ever, real water drinking be.
Since I already Waterworld mentioned at the beginning of the play, let it go on me. Why had to pee in a cup of fresh drinking water to Kevin Costner? Use he could not simply the miles of sea water around it? And why he put the Cup on the unsteady surface of a boat and urinate into it, instead of holding it closer to his bladder? Stuff like this just bothers me, or maybe it's just the film Waterworld.
