When you've come across gadgets like NoPoPo's pee-powered battery, you shouldn't be surprised that a can of Coke is all that's needed to power this concept handset conjured up for Nokia by U.K. designer Daizi Zheng.
We're not convinced that the cylindrical design of the phone, which doubles as a tube you can drink from, will win hearts, but the idea does sound fitting for a tropical island. Even better if the chilling technology we wrote about recently can be incorporated. The designer didn't elaborate on the technicalities, although terms like sugary drink, enzymes, water, and oxygen were mentioned. The claim is that this concept has the potential to last three to four times longer than the conventional lithium cells.
