Sony's biotech battery has a sweet tooth. It sups on glucose for energy (much like some of us) converting the sugar within beverages such as fruit juice and even Pocari Sweat into electricity.
A four-cell array is reportedly capable of generating up to 50mW of power, enough for small devices at the moment. For a glimpse into the future of alternative power cells, check out the video of the battery seen powering a desk fan and speakers attached to a Walkman, after being juiced up on a sugar solution.
The Bio Battery imitates real life by using enzymes to break down the glucose to generate electricity. Because it's made of a vegetable-based plastic, the worst that could happen to it are--eek--ants. A blessing given Sony's rather unfortunate notebook battery recall of last year.
