Hydroelectric Cell produces electricity from water without using chemicals

Countries around the world are continuously pursuing green and hygienic technology to generate power from available limited resources of nature. Power generation from renewable energy sources has reached equality with that from conventional forms. But the portability of energy derived from cleaner sources has always been a challenge.

Conventional batteries use elements such as lithium-ion and lead-acid, which are toxic, have a serious risk of explosion, are expensive and harmful to the environment.

Scientists at Delhi’s National Physical Laboratory (NPL) have found a novel way of producing electricity from water at room temperature without using any power or chemicals. They invented a device called Hydroelectric Cell that can generate power using only a few drops of water. The device is able to generate about a quarter ampere current at less than 1V, which is sufficient to power a small plastic fan.[Readmore]
