Last month, we featured Urine Powered Battery. This time, it is a mobile phone powered by Coke (yes, the Coca-Cola). Daizi Zheng designed the “green phone” for Nokia as a final University project.

Though the traditional lithium ion batteries are not considered hazardous in the U.S., they do pose great challenges for landfills. The lithium ion batteries contain metals such as cobalt, copper, nickel and iron. So, there is always a risk of water contamination. The “green phone” is based on the concept of using bio battery instead of using the lithium ion battery. The bio battery generates electricity through carbohydrates (mainly sugar), utilizing enzymes as the catalyst.

The bio battery seems to run longer with a single charge. Daizi Zheng claims that “bio battery has the potential to operate three to four times longer on a single charge than conventional lithium batteries”. The bio battery is also easy to dispose. The battery leaves behind only water and oxygen as it dies out. To make is even sweeter, the battery could be fully biodegradable.

Although Nokia decided not to develop the green phone further, other electronic companies are expected to come out with similar bio batteries in next few years.

Meanwhile, Here are some of photos of the futuristic “green phone” powered by the Coke:
