Phone that Runs on Coke

This seems like a perfectly good waste of Coke to me, but I like Diet Mountain Dew, so I suppose this is a non issue.

As a result of my research, I discovered that conventional phone batteries are: expensive, harmful to the environment and difficult to dispose of. In addition, the conventional battery manufacturing process consumes many valuable resources. The concept is based on the idea to create a pollution free environment by using bio-batteries as an alternative to conventional batteries. A bio-battery is an ecologically friendly, energy supply system which uses enzymes as a catalyst to generate electricity from carbohydrates (currently sugar). In order to use the bio-battery as a power source for the phone all that is required is a small supply of a sugary drink. Once the battery dies only oxygen and water remains. Bio-batteries are fully biodegradable and have, on a single charge, a potential life-span three to four times longer than conventional lithium batteries. Meanwhile, bio-batteries are a whole new way of looking at batteries and afternoon tea.
