Soon, a device that runs on a few drops of water could revolutionise the way electricity is generated, thanks to a team of scientists at Delhi’s National Physical Laboratory (NPL). Researchers have developed a novel way of producing electricity from water at room temperature without using any power or chemicals. The device named, Hydroelectric Cell, generates electricity using nothing except a few drops of water.
Chief Scientist Dr R. K. Kotnala and his research partner Dr Jyoti Shah of NPL have demonstrated that this panel can generate up to about a quarter ampere current at a little less than one volt. They used Nanoporous Magnesium Ferrite to split the water into Hydronium (H3O) and Hydroxide (OH) ions spontaneously, silver and zinc as electrodes to make a cell that produces electricity. The hydroelectric cell that uses magnesium ferrite of 1 sq. inch size produces 8 mA current and 0.98 volt.
According to a paper published in the International Journal of Energy Research, magnesium ferrite of 2-inch diameter produces 82 mA current and 0.9 volt. Now, the hydroelectric cell material design has been improved and a 2-inch diameter material generates 150 mA current and 0.9V.
