I would immagine you would need some kind of dehydration machiene to rapidly remove the water. It would be cool to try, it would stink up your kitchen if you boiled it. If you just let it evaporate it would definately not work, it would take too long and bacteria would form before you got the byproduct. I hade a friend whos cat peed in the dryer and the piss turned into crystals in the dryer....it stunk too. If you try it out, post how it went!
