We previously saw how researchers found a way to power cars with human waste. Now, chemistry experts have learned how to convert human urine into fuel cells. Dubbed “pee-power,” the advance could open up a literally free flowing force of energy.
Chemistry postdocs Shanwen Tao and Rong Lan at Heriot-Watt University’s School of Engineering and Physical Sciences in Edinburgh have shown that urea, an organic chemical compound produced when the body metabolizes protein, can be an excellent source of energy. However, urea or “carbamide” is non-toxic and, of course, plentiful.
