A spectacular façade isn’t all that the Kuggen, an office building in Gothenburg, Sweden, is all about. It is totally sustainable too. Designed by Winngardh Arkitektkontor, the Kuggen was inspired by a cog wheel (hence its name in Swedish) and the saw-toothed edges of a leaf.
YeZ, this is just a concept car, but consider the possibilities. Developed by Shanghai Automotive Industry Corporation (SAIC) in partnership with General Motors and Volkswagen, YeZ, which means “leaf” in Mandarin, not only absorbs carbon dioxide and water molecules from the atmosphere, it exhales oxygen. Through solar panels on its roof and wind turbines in its wheels, YeZ generates energy that it stores in its lithium ion batteries. YeZ is like a mechanized photosynthesis process. It is still a concept and only seats two, and no one has said how fast it can go, but consider the possibilities.
