Coca-Cola powered cell phone disgned with A Chinese designer

Daizi Zheng came up with the idea of a cell phone powered by sustainable energy sources. She designed a battery that uses enzymes generate electricity from carbs. That way she can use sugary drinks like Coke or Pepsi to charge the battery. Better still, the by-products of the charging process are just water and oxygen!

As a side-benefit, this battery is more efficient. It can last 4 times as long as a standard lithium battery on a full charge. And the phone is biodegradable. Check out this article to see pictures of how it works!
