Wired has a great article on NASA's attempts to recycle urine into drinking water. Excellent read!

One gallon of that stuff would dramatically improve my family's quality of living. Two gallon's and we'd have a whole new life!
Alan Shepherd's first 15-minute suborbital flight was so short that no one thought to install a urine receptacle in his space suit. At T-minus 15 minutes, an electrical problem caused an 86-minute delay on the launchpad.
