Would you like to drive a car powered by urine? Of course you would. Not only is it an awesomely efficient concept, but, according to Gas2.org, "using urine as a source of hydrogen to power the cars of the future is a serious undertaking and based on completely sound science." The scoop:[R]esearchers at Ohio University have found that urine makes a much better starting point for generating hydrogen than water. The hydrogen found in urine is bonded much more loosely than in water. So loose, in fact, that by using simple and cheap materials hydrogen can be generated from urine using 1/3 of the voltage needed to make hydrogen from water.The researchers see a much wider application for this technology in wastewater treatment plants by generating hydrogen while treating the waste simultaneously.Even if these researchers aren't the first ones to ponder it, this stuff makes me super excited. I just hope it actually happens.Photo (cc) by Flickr user justin.
