Sony unveils battery that runs on sugar

Last week Sony presented a new bio battery that runs on sugar. The firm says the battery generates enough electricity to power a MP3 player and a pair of speakers:
The bio battery's casing is made of a vegetable-based plastic. It measures 3.9 cm (1.5 inch) along each edge and works by pouring sugar solution into the unit, where enzymes break it down to generate electricity.

Test cells had an output of 50 milliwatts, Sony said.

"Sugar is a naturally occurring energy source produced by plants through photosynthesis," Sony said in a statement.

"It is therefore regenerative, and can be found in most areas of the earth, underlining the potential for sugar-based batteries as an ecologically-friendly energy device of the future."

The company said it aims to produce the batteries for commercial use, without specifying when.
