BioFuel: fuel cells of lesser god? Answered
I was just reading one of the biochemistry articles I have, and noticed that urea, the main componant of urine, has an extra, and not so tightly bound hydrogen atom attached to it.
I am thinking renewable fuel cell fuel here, but other then smell, are there any other draw backs to using this? I mean, I realize the salt content may or may not be a bit hard on metal parts etc. .. Feed back welcome !
