Strange, now NASA is interested in recycling urine. I recall some months ago a story and video on NBC Nightly News showing urine being ejected into space (I don't remember if it was from the space shuttle or the ISS). I thought at the time-what a waste-that is our planet's water lost forever. Why wasn't this returned to earth and sent down the sewer? Eventually, it would have entered the natural water cycle.
