Less waste, cleaner air, and a good transportation system - these are all things that would make the city of tomorrow more livable and more sustainable. Researchers at a number of Fraunhofer institutes have joined in the "City of Future” project to find ways to make them a reality.
Among the many ideas under investigation are building facades that are equipped with power stations to generate energy, and cars that help clean the air rather than pollute it. Today, these ideas only exist in a virtual model, but we went to meet the scientists who are working to bring about the city of tomorrow.
