Sony saves the planet with… grape juice Bio Batteries?

Share

biobattery-sony.jpgI am quite often fuelled by grape juice, but it’s of the £4.99-from-Sainsbury’s Chilean variety, which isn’t exactly eco-friendly. But Sony’s newest technology isn’t about vino: it’s about using glucose extracted from grape juice to power gadgets.

It’s a joint project between Sony and Kyoto University’s agriculture department, and involves enzymes breaking down the glucose in the juice (or syrupy sports drinks) to generate 50mW of power – currently enough to power little MP3 speakers.

Quick, buy shares in Lucozade! If this takes off, they’ll shoot through the roof. Probably. There’s a video via the link below, to see how it all works.
