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.
..."Think of an electric car battery made from silicon that will turn into sand that would be recycled into silicon and then into power again," suggested Ein-Eli. "This would take about 10 years more and be revolutionary. It could be used in any portable electronic device or be integrated with solar or wind power as well as electric energy."
A number of foreign and Israeli companies have already contacted him and shown strong interest in the battery, he said.
Any bets on how long, if this works, before enviro/petro crowd starts screaming that such batteries are environmentally hazardous |
