Chinese designer Daizi Zheng has designed a concept mobile phone for the known brand Nokia that can be powered by sugary drinks such as our daily favorites, the soda. This concept mobile phone has the ability to run on batteries that uses enzymes to generate electricity from carbohydrates. Assuming that the sodas used are leftovers, this can be an eco-friendly product. However, if the soda used is bought just to have something to fill into the phone, this can be a questionable product, for soda manufacturers are one of the primary contributor of air pollution. In addition, bottles, cans, and plastics can be an addition to our land fills if not recycled.
