This intelligent cup grows when you start to pour coffee in it. Made from  stretch material with a metallic case, this could be a future solution.

Take-away coffee cups are a true icon of everyday life, but we have to come up with sustainable solutions to reduce the 58 billion paper cups of coffee that goes to waste each year. We must become more responsible. We must change our attitude for a better future.

This is a portable coffee mug that can change shape through nanotechnology, it is charged with solar energy, or kinetic energy when solar energy is not efficient. Considering the nano technology is continuously developing in the future batteries will become increasingly smaller and less flexible (at Stanford University, a group of researchers have already managed to do a battery of photocopy paper).
