Chinese designer Daizi Zheng has created a mobile phone that uses sweet drinks like Coca Cola instead of lithium batteries.Zhenghas been working on this revolutionary device for Finnish cellphonegiant Nokia, and claims he has come up with a way of using sugar-baseddrinks to power mobiles. Any sweet drink, even sugar-sweetened waterwould be enough to keep the phone running much longer than lithiumbatteries.The bio-battery invented by Daizi Zheng generateselectricity from carbohydrates, using special enzymes as catalysts. Inthe process, the device generates oxygen and water. The designer claimshis sugar-based bio-battery lasts up to four times longer than a fullycharged lithium battery and is much easier to recharge: just pour somemore sweet fuel.Lithium batteries are very expensive andharmful for the environment, so if Zheng’s Coke-powered cellphone turnsout to be real, it would be a significant breakthrough.
