Urine-Powered Batteries
Contributed by MondoChee on 23 Aug 2005 - 04:02

Singapore scientists at the Institute of Bioengineering and Nanotechnology (IBN) have developed the first urine-activated paper battery which will generate enough electricity to power fully integrated biochip systems, making it the perfect power source for cheap, credit card-sized disposable healthcare test-kits for diseases such as diabetes.

The urine battery unit comprises of a cathode sandwiched between an anode and an electron-collecting layer. When a droplet of urine (0.2ml) is placed on the device, the capillary force drives the urine into the cathode layer and the battery is activated.

It was about time they did something useful with urine.

Cool, that means that now we have power coming from ..... (ok, I mustn't finish that sentence)....... whatever, you got the point.

[glow=purple,5,300]So this also means that, we can have infinite energy?? ??

Maybe we can get an easy job now, LOL.[/glow]

Hmm, prices, the technollogy wouldn't be free, unless it's so easy a 10 year old kid can make it in 5 minutes....

How much does a urine battery last? they won't be business if they have a low power and/or duration.

will generate enough electricity to power fully integrated biochip systems

Ok, how much is that?
