Sony’s battery boffins seem to have learnt some lessons from the previous few month’s, ahem, problems. They’ve developed a battery that generates power from sugar and, they claim, can create enough power to run an MP3 player.
The so-called “bio battery” generates electricity by mixing enzymes with a sugar solution. They break the sugar down into useable power, much like the process of converting food into energy in the human body.
