Pee Power!


It's TRUE! Create power from your own pee!

Calvin peeing!
Apparentley the urea from urine is better than water in creating power. This would be because there are twice as many hydrogen molecules than in plain old H2O.

Urea or carbamide is an organic compound with the chemical formula (NH2)2CO. The molecule has two amine (-NH2) groups joined by a carbonyl (C=O) functional group. It is solid, colourless, and odorless (although the ammonia which it gives off in the presence of water, including water vapor in the air, has a strong odor). It is highly soluble in water and non-toxic. Dissolved in water it is neither acidic nor alkaline.

Urea is used in SNCR and SCR reactions to reduce the NOx pollutants in exhaust gases from combustion from diesel, dual fuel, and lean-burn natural gas engines. The BlueTec system, for example, injects water-based urea solution into the exhaust system. The ammonia produced by the hydrolysis of the urea reacts with the nitrogen oxide emissions and is converted into nitrogen and water within the catalytic converter.

But - now the power part...


The Carbamide Power System prototype can break urea or urine from humans or animals down into water, nitrogen and CO2, and also produce electricity at the same time. Unlike existing fuel cells that require catalysts made from precious metals like platinum, the "Youtricity" research group's prototype uses a cheaper catalyst and less expensive membranes.

If these scientists can actually make the system work, the whole thing will be golden.
