Sony’s Sweet New Battery
Sony just announced an interesting development: An advanced form of the classic potato-powered battery. These “bio-battery” cells can essentially convert sugars into useable electricity. It’s still a long way from recharging your iPod by adding some soda, but Sony did demonstrate running a fan from a splash of sports drink, and one of their portable music players from cells filled with grape juice.
TBS News (J) has a short video of the two demos, or there’s a much longer version on YouTube, if you prefer.
The story’s all over the international media; here’s a Reuters link to read a bit more, if you’re interested.
