Scientist Garardine Botte of Ohio University has developed an electrolyzer that can extract hydrogen from urine for use in fuel cells. Because hydrogen is less tightly bound to the nitrogen in urea (NH2)2CO, only 0.37volts are needed to oxidize urea – less than a third needed to split water. According to Botte, the technology can be easily scaled up to power a hybrid or electric car, with power for the extraction aided perhaps by a solar panel on the car roof.
