Sony develops a bio battery that runs on sugar
By Sean P. Aune
While they may not be the most practical power source to carry around with you, Sony has come up with a sugar-powered bio battery.
Sony, creators of a laundry list of gadgets over the years, has come up a battery that runs on sugar.
How does it work? The batteries contain a mixture of sugar, enzymes, and water. First, the enzymes digest the glucose and they, in turn, release hydrogen ions along with free electrons. Then the hydrogen and electrons absorb oxygen to form water. This then somehow produces 50 mW of electricity per battery. As you can see in the picture though, it still takes four of them to power a tiny Walkman.
The batteries measure approximately 1.5″ on each side and are made from vegetable-based polylactate plastic. Each one contains 40 ccs of sugar, enzymes, and water. As with all technology, they will probably get smaller and powerful with time, but for now, it is difficult to picture anyone walking around with these, powering their favorite gadgets.
Sony promises they will market the batteries at some unknown date in the future.
