Guest Stuge Posted August 24, 2007 Report Share Posted August 24, 2007 Looks nice Sony, one of the world's largest battery makers, said it had succeeded in creating a battery that produces electricity by breaking down sugar. The bio cell, which measures 39 millimeters cubed, delivers 50mW (milliWatts) -- a world record for such a cell, according to the company. A video provided by Sony shows four of the cells connected in series delivering enough energy to power a Walkman music player. The battery uses glucose solution as a fuel. A second video shows a small fan being powered by the cell with a glucose-based sports drink used as the fuel. As in other cells, power is produced through a flow of electrons between a cathode and anode. In the bio cell sugar-digesting enzymes at the anode extract electrons and hydrogen ions from the glucose. The hydrogen ions pass through a membrane separator to the cathode where they absorb oxygen from the air to produce water as a byproduct. The electrons flow around the circuit outside the device producing the electricity needed to power it. Details of the bio battery were accepted as a paper at the 234th American Chemical Society National Meeting and Exposition that is taking place this week in Boston. Sugar is naturally occurring so the technology could be the basis for an ecologically friendly energy source. Companies such as Sony are researching numerous technologies that could replace the dominant lithium-ion cells as a clean power sourceOne of the most talked about is fuel cell technology. While hydrogen-based cells have taken off for home or automobile use, versions based on methanol for use in electronics products have yet to be commercialized. Toshiba and NEC are among the companies that promised methanol fuel cell-based laptops in previous years, but each time, technology launches have been delayed.http://www.infoworld.com/article/07/08/23/...-battery_1.html Quote Link to comment Share on other sites More sharing options...
bobt Posted August 25, 2007 Report Share Posted August 25, 2007 wonder if it works with Coke!!Thanks Bob Quote Link to comment Share on other sites More sharing options...
gotthat Posted September 1, 2007 Report Share Posted September 1, 2007 just amazing tech from Sony, two pics for the related news Quote Link to comment Share on other sites More sharing options...
DannyB37 Posted September 2, 2007 Report Share Posted September 2, 2007 I heard about this, great news for the green people (and I don't mean those mars people) Quote Link to comment Share on other sites More sharing options...
