The Bio Alternative by Yanko

What would a cell phone and a can of Coke ever have in common? Think of all the times your cell battery started running low and you weren't anywhere near a charger. What if you could just stop by the closest vending machine or foundtain drink dispenser and and fill up your cell phone? And, *poof*, instant battery life! This new cell phone design by Daizi Zheng uses a battery that feeds off of carbohydrates (sugar). And, when the battery runs out, the only byproducts are oxygen and water. There's also a design by Tryi Yeh that is powered off of alcohol. Cheers!
