Sony Runs Walkman Off Sugar-Based Bio Battery

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.'"

All you can do is complain?

Reading all these responses makes me think that all you can do is complain about this or that. What about, this is neat, maybe battery life will be longer, maybe I don't have to cry Noooo when I'm on a plane and my battery died. Also I have noticed that just about everyone turned into some sort of activist. Discussions are mostly about *impact* on this or that, not that much on the technology. Also it seems that on every opportunity a political slant is added to every comment. I thought this was mostly a tech site ... I must be wrong.

On that note, the huge impacts with food price changes and all that hinge on one HUGE assumption: mass adoption. Not to mention the time until this will actually be sold and OTHER inventions/technological advances made at the same time. Who knows, we may find a way to produce said sugars from OTHER sources ... anyone think of THAT?
