Researchers at Heriot-Watt University in the United Kingdom have figured out how to use urea as a fuel for low-cost fuel cells. Fuel cells are a great form of alternative energy for all kinds of things — cars, submarines, remote power stations — but concern over the cost of hydrogen and its explosive nature keep the technology from being widely used. Using urea — which is present in all animal and human urine — instead of hydrogen could be a low cost alternative to these super low-emission systems.
Dr. Tao believes that long term potential applications of the Carbamide Power System include in submarines, among the military, power generation in an isolated or remote areas such as deserts or on islands. As the process breaks the Urea or urine into water, nitrogen and carbon dioxide, it could also be used to reprocess waste water, with electricity as a by product.
Dr. Tao said, “Growing up in rural eastern China I was aware of the use of urea as an agricultural fertiliser. When I became a chemist and was looking at fuel cell development I thought of using it in the process.
If this renewable material can be used as a commercially viable and environmentally friendly energy source then many people around the world will benefit
Tao and Lan’s fuel cell uses a much less expensive membrane and the components are totally harmless — urea is used as fuel instead of highly flammable and expensive hydrogen. Even better, this fuel is totally renewable — just keep drinking those 8 glasses of water a day.
Daus : huh? cool right? if this happen, we no longer need to use petroleum as fuel..we just need to pee in a plastic and put it in our car fuel tank.LOL!..
