Why eat it when you can use it to power your MP3? Huh? I'm talking about sugar (glucose) powering your MP3. It's not the most aesthetically pleasing battery but it's a start. Better than the lithium ion batteries Sony had in their laptops last year. In case you forgot they were the batteries that had to be recalled due to a little problem called fire.
To learn more about the battery, you can check out the
Sony site
This site will give you a chance to brush up on your Japanese also as there's no English.
