Aqua Power System, from Japan, has unveiled the NoPoPo batteries that are rechargeable via liquid that’s injected into the battery chamber. Yes, it will run off your urine if that’s where you thought this was going to lead. But let’s try and be mature about this. The rechargeable batteries come in AA and AAA and the basic principle behind the pee-powered NoPoPo’s is that a mixture of magnesium and carbon reacts with the liquid you choose to inject, which in turn produces up to 500 mAh of life. Not the greatest battery life, but it’s a start. Fly on over to Japan and pick some up for me. Please.
