Coca Cola-Powered China Mobile with Bio-Battery
Chinese designer Daizhi Zheng has been working on a revolutionary device for Finnish cellphone giant Nokia, he has created a mobile phone that uses sweet drinks like Coca Cola instead of lithium batteries. Any sweet drink, even sugar-sweetened water would be enough to keep the phone running much longer than lithium batteries.
The bio-battery invented by Daishi Zheng generates electricity from carbohydrates, using special enzymes as catalysts. In the process, the device generates oxygen and water. The designer claims his sugar-based bio-battery lasts up to four times longer than a fully charged lithium battery and is much easier to recharge: just pour some more sweet fuel.
Lithium batteries are very expensive and harmful for the environment, so if Zheng's Coke-powered cellphone turns out to be real, it would be a significant breakthrough.
