Water batteries – Aqua Power System

Aqua Power System is a manufacturer of water-powered batteries, and the result is impressive. batteries are actually lighter than real batteries and are holding a couple of chemicals such as Aluminium, Copper and other secret stuff. By inserting water inside, you get a 300-600mA at 1,5V generator and that can be recharged with water up to 5 times. What’s amazing is that you can actually store them for tens of years !
