Coca Cola-Powered Cellphone

Chinese designer Daizhi Zheng has created a mobile phone that uses sweet drinks like Coca Cola instead of lithium batteries. Zheng has been working on this revolutionary device for Finnish cellphone giant Nokia, and claims he has come up with a way of using sugar-based drinks to power mobiles. 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.
