Batteries that run on water to produce electricity.

Products

H20 Battery from Tango Group

Tango Group has a line of H20 Battery products including clocks and calculators

Product line utilizes water-powered battery that consists of two electrodes made of special alloys, which, when immersed in water, the resulting chemical reaction produces electricity. Simply refill the battery as the water evaporates - typically every 2 to 3 months. The battery has a minimum continuous life of 2 years.

Magnevolt

• Magnevolt - The water activated battery is popular in the oceanic field and military. It has a high energy density, long shelf life and good low temperature performance. They use Magnesium Silver Chloride and Cuprous Chloride Magnesium with no electrolyte until it is immersed in the salt water or fresh water. As long as the batteries remain sealed they have indefinite shelf life.

In the News

• Batteries powered by water - Susumu Suzuki, the president of Tokyo-based building material maker TSC (Total System Conductor), has invented water-powered batteries, which have an electric current as powerful as that of a standard manganese dioxide battery. (Reuters; Nov 8, 2006)

• Batteries Can Now Be Powered by Water

• New power source - Larry Kostiuk at the University of Alberta in Canada, is working on a water-powered battery. Its special trait: creating electricity directly from water on the tiniest scales. As water moves through microscopic channels within a glass or ceramic-filter tube, electricity is converted directly from water. The experimental tube, about 2 centimeters in diameter, has about half a million tiny channels or holes through which the water is inserted by a hand-operated syringe. As water travels over the surface of the channels, it becomes electrically charged when its ions rub up against the solid surface. Scientists placed electrodes at the ends of each channel and then extracted electrical energy as current flows between the electrodes. Right now currents are very low, around 4 microwatts, but millions of channels could be added together to increase the power output enough to create a water-powered battery.
