Urine Powered Batteries

Use your own pee-sources… I mean resources to recharge these batteries! Before you go flushing all that natural energy down the toilet, you may want to check if your batteries are low in that remote.

In 2005, Scientists in Singapore developed a battery powered by urine. The Scientists were able to produce electric power using liquid as a catalyst thanks to a special mixture of magnesium and carbon inside the batteries.

Now, a Japanese company has brought this urine powered battery technology to market with the NoPoPo (Non-Pollution Power) Aqua Batteries. Just use the included plastic pipette to inject urine into the battery chamber. Grossed out by pee? You can also use other types of liquid including beer, apple juice, cola, and saliva and of course urine.

A single urine powered AA battery can power a flashlight for about 20 hours (500 milliamp-hours). Not exactly the most powerful battery on the shelf, but it’s a great start for this environmentally friendly energy technology. The NoPoPo aqua powered batteries are currently only available in both AA and AAA sizes, but the company has future plans to produce all common battery sizes.
