Fuel of the future: Your own urine?
A team at Ohio University has developed technology to turn pee into hydrogen fuel that could power specially adapted cars.
Gerardine Botte, a professor of chemical and biomolecular engineering, said two compounds in urine — ammonia and urea — could be a source of hydrogen.
By placing a hydroelectrode in the urine and applying an electrical current hydrogen gas was produced sufficient to power a hydrogen cell.
Ammonia and urea hold their hydrogen atoms more loosely than water, Botte explained, so less electrical current is needed to produce hydrogen.
