Hydrogen-powered cellphone
The Electro-Mechanics division of Samsung says it has developed a hydrogen-powered prototype cellphone, one which could soon have a commercial equivalent. The new technology consists of a special hydrogen generator and a micro-fuel cell; when the phone is turned on, metal and water react to produce hydrogen gas, which is then transferred to a fuel cell where oxygenation releases energy. Most conventional versions of this technology are said to require methanol in place of water.
