We've heard of solar-powered phones, hydrogen-powered phones, and even wind-powered phones--but Chinese designer Daizi Zheng's sustainable cellphone concept is powered by an unusual and unexpected source: Coca-Cola soda.
The Design Blog describes the Coke-powered phone:
Designed for the Finnish brand Nokia, the Eco-Friendly cellphone runs on an innovative battery which makes use of enzymes to generate electricity from carbohydrates. The new mobile phone concept apart from harnessing clean energy from sugary drinks like Coke or Pepsi, which generates water and oxygen, also works about four times longer than contemporary lithium batteries on a single charge. Moreover, the handset is fully biodegradable.
