Batteries recharged with water
Ciro Altabás sent me a link about a Japanese company that is selling urine rechargeable batteries. This thing about the urine is a false rumor, the batteries are rechargeable with WATER, but they could also be filled with any other liquid like for example urine or saliva; that’s why urine “false”/exaggerated rumors appeared. In many blogs and news sites it is so exaggerated you could think that nowadays Japanese people are peeing on their digital cameras in order to recharge them.
The batteries are called NoPoPo, they can be found in packs with 2 batteries and a water filling adapter. The batteries keep their charge during 10 years and can be recharged around five times until the carbon and magnesium they have inside is depleted. The NoPoPo batteries are environmentally friendly, no mercury or any other contaminant components.
