Sony sugar-based bio battery

Sony said it has succeeded in creating a battery that <A HREF="http://www.infoworld.com/article/07/08/23/Sony-runs-Walkman-off-sugar-based-bio-battery_1.html">produces electricity by breaking down sugar.</A> 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.
