Wouldn't it be great if you could charge your phone by pouring Coca-Cola into it? Like the Delorean in Back To The Future? You'd never have a flat battery again! Of course, it'd be even better if it was water-compatible.
This concept phone was created by designer Daizi Zheng, who said of the design:
"The concept is using bio battery to replace the traditional battery to create a pollution free environment. Bio battery is an ecologically friendly energy generates electricity from carbohydrates (currently sugar) and utilizes enzymes as the catalyst. By using bio battery as the power source of the phone, it only needs a pack of sugary drink and it generates water and oxygen while the battery dies out."
It's a great idea, but I very much doubt we'll see Nokia adopting it anyday soon. [Daizi Zheng via LikeCool]
