Sony runs Walkman off sugar-based bio battery

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). The bio cell has sugar-digesting enzymes at the anode that 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.

Sweet! What other applications can the sugar battery have?

I would think that anything where you would consider using a fuel cell. This is so much simpler and easy to maintain. This will not hurt the environment and looks to be as efficient as a fuel cell. I think the one thing this will hurt is fuel cell adoption.
