Now this is a novel way of recharging your battery. The NoPoPo (non-pollution power) Aqua Battery runs on water. It’s also been tested with beer, apple juice, cola, saliva, and urine.
The liquid that is inserted into the base with a teat pipette reacts with a combination of magnesium and carbon to produce a charge, which can run a small handheld torch light for up to 20 hours. They can also retain their charge for 10 years, making them perfect for emergency situations, and better for the environment.
The NoPoPo battery is intended for home use, so pee-charging it in the middle of the street is not recommended.
