Walkman powered with sugar-based bio battery

26 August 2007 17:59 by James "Dela" Delahunty | 2 comments

Sony Corp. has taken a step forward by creating a battery that produces electricity by breaking down sugar. The company, which is one of the largest producers of batteries in the world, sees this as a breakthrough in bio battery technology. The bio cell, which measures 39 millimeters cubed and delivers 50mW, setting a world record for such a cell.

The battery uses glucose solution as a fuel. In example videos provided by Sony, a small fan is powered by the cell with a glucose-based sports drink. Another example shows four of the cells connected in series to deliver enough power to operate a Walkman music player. Sony's image was seriously hurt last year when the company issued a massive recall of lithium-ion cells.

Sugar is naturally occurring, making the technology the basis for an ecologically friendly energy source. Many electronics companies are currently researching technologies that could replace the dominant lithium-ion cells as a clean power source for portable electronics.

I just hope that the Walkman does not get diabetes from all the sugar, unless you do the right thing and walk or jog with your walkman then you will burn off the fat and sugar :P [ + quote]
