I guess if the concept cell phone became a reality, Coca-Cola would be more popular than now, even those who never drank Coca-Cola before might buy it because Caco-Cola would be the energy for your Nokia cell phone.
The unique eco-friendly concept cell phone with the Nokia branding is designed by Daizi Zheng, a Chinese designer in London. The cell phone has a special tube-shape, but the most brilliant spot is the bio battery, which is able to use carbohydrates and enzymes as the catalyst for producing energy needed by cell phone. So you can use any sugary drink as the cell phone energy. I don’t know whether the Coke Zero could be used as the energy.
It’s really great idea, and according to the designer’s accounts, the bio batteries have the potential to operate three or four times longer on a single charge than traditional lithium batteries and it could be fully biodegradable, so it couldn’t create pollution problems. Just one problem, its appearance should redesign for easier to carry.
