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.'"

    Well I think we have found a better use for carbs: an energy source for walkmen. When I ate a lot of carbs I ended up being over 100 lbs overweight. Cut them out and the weight drops off.
