Sand Power

clipped from www.jpost.com A new kind of portable electrochemical battery that can produce thousands of hours of power - and soon replace the expensive regular or rechargeable batteries in hearing aids and sensors and eventually in cellphones, laptop computers and even electric cars - has been developed at Haifa's Technion-Israel Institute of Technology. The unique battery is based on silicon as a fuel that reverts to its original sand. The battery can also be left on the shelf for years and inserted into a device to provide immediate power. It was developed over the last two-and-a-half years by Prof. Yair Ein-Eli of the Technion's materials engineering department, with collaboration by Prof. Digby Macdonald of Pennsylvania State University in the US and Prof. Rika Hagiwara of Kyoto University in Japan.
