Soon we can stop fighting for water at the refrigerators, and instead just pee in a special bag, wait for 4-6 hours, and then have perfectly drinkable sugary sports drink to enjoy. No external power needed, because it relies on the passive property of fluids called forward osmosis. NASA will make an astronaut test this on the Atlantis leaving this Friday, with a blue potassium-rich solution instead of pee, which I feel is a bit chicken.
