http://www.livescience.com/technology/070325_sugar_batteries.html Wide commercial use of such batteries will probably drive sugar prices through the roof. Like corn-based methanol for cars, it looks good in the lab, but the economics of mass production have a serious impact on the price of the raw ingredient. On a side note, this could be the core technology for robots that feed themselves. Imagine a robot that stops every few hours for a swig of syrup, or if operating in the wild, eats berries and fruits as it finds them.
I like the Urine powered batteries better http://www.livescience.com/humanbiology/050816_urine_battery.html
Does that mean we will start to see supercharged hybrid ants? bionically powered by eating batteries?
