Coffee Break

as weird as it might sound it's completely true. it went for testing at first and became reality at the moment.

To make the battery, Lee and his colleagues soaked a piece of paper in a solution of copper chloride and sandwiched it between strips of magnesium and copper. This sandwich was then laminated between two sheets of transparent plastic.

When a drop of urine is added to the paper through a slit in the plastic, a chemical reaction takes place that produces electricity.

The prototype battery produced about 1.5 volts, the same as a standard AA battery, and runs for about 90 minutes. Researchers said the power, voltage, and lifetime of the battery can be improved by adjusting the geometry and materials used.

Urine contains many ions (electrically charged atoms), which allows the electricity-producing chemical reaction to take place in the urine battery. Other bodily fluids, such as tears, blood, and semen, would work easily as well to activate the battery.

NoPoPo (Non-Pollution Power) Aqua Batteries are available in both AA and AAA form, although the company page shows they are producing the technology for all sizes of battery, and can only be currently purchased in Japan.

The batteries can be recharged with various different fluids using the new development which forms electric power using liquid as a catalyst.

Each time the battery is recharged it has a lower power level than the time before and the life cycle allows for about 3 to 5 recharges before disposing of the battery. Each battery can potentially keep its charge for up to 10 years which could be great for many life saving devices in remote locations.

Since the battery does not contain mercury and other harmful materials, it can be easily disposed of without worry for the environment.

So the next time your batteries let you down, just pee on them. (*Will probably help if they are produced by NoPoPo.)
