The Waterlight
The Waterlight is a revolutionary low-cost invention that uses seawater to recharge its batteries. It’s an innovative LED lamp that was designed for neighborhoods with little to no access to electricity. The light uses a water-activated magnesium battery that causes a reaction when it comes into contact with salt water or brine. The chemical reaction creates electricity to power the LED lamp, the batteries can be recharged with ocean water, regular saltwater or even urine in emergency situations.
