Sony Runs Walkman Off Sugar-Based Bio Battery

Posted by ScuttleMonkey on from the sweeeeeet dept.

StonyandCher writes "Sony has created a battery that produces electricity by breaking down sugar. The bio cell, which measures 39 millimeters cubed, delivers 50mW — a world record for such a cell, according to the company. '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.'"

    Perfect complement to a low-carb diet. If you've been wondering what to do with all that Easter and Christmas candy you get but can't have anymore, well Sony has the solution. One Cadbury egg can play several hundred hours of music.
