Getting Electricity From Urine

Posted by John Farrier in Science & Tech on July 10, 2009 at 8:00 am

Don’t dispose of that liquid gold, there’s money to be made from the hydrogen in it. Hydrogen can be an abundant source of energy, but it’s hard to store inexpensively:

Gerardine Botte, an Ohio University professor, sees the liquid as a solution thanks to the particular composition of its major component, urea. Its make-up, a 2-to-1 ratio of hydrogen and nitrogen, is convenient because hydrogen can be extracted from nitrogen using much less electricity than that needed to, say, pull apart hydrogen and oxygen. (It’s a matter of 0.037 Volts versus 1.23 Volts, if you really need to know.)

Botte has recently come up with a nickel-based electrode that can do just that: dip the electrode into urine, apply electrical current, and voila, hydrogen is released. While the research is still in an initial phase, it’s possible that urine could power cars, homes, and various devices in as near of a future as six months from now.

NoPoPo Battery is Powered by Pee-Pee

Posted by Alex in Gadget on January 14, 2009 at 3:23 pm

Did your gadget just run out of juice and there isn’t a RadioShack around for miles? Not a problem if you have this "rechargeable" NoPoPo (No Polution Power) battery. Just … um, pee into it:

The Nopopo batteries use a combination of magnesium and carbon that can be mixed with a variety of fluids (including urine) to produce a charge. These batteries only last around 500mAh, which is far less than your average alkaline AA battery, but at least you won’t have to kill the earth to recharge them.
