Well, excrement does give off ammonia, a cleaning product so I guess that makes sense. But seriously...how can they claim it will be 'tasty'? Urine is supposed to be salty, and it smells bad. And you're talking about an animal with a much different digestive system than our own; it'd be bad enough drinking human urine, as I understand sailors used to have to do sometimes, but of a cow? Ugh...I can't even believe this guy is even being successful at spearheading this thing.
