How cool would it be to tell people you live inside of a wind turbine? Designed for the port city of Rotterdam, the Dutch Windwheel is a concept for a sustainable landmark that would be able to house 72 apartments within a circular steel and glass frame, while also serving as a silent, motionless wind turbine. In addition to harvesting energy from the wind, the structure would be equipped with facilities to capture rainwater, recycle tap water and also produce biogas from the residents' organic waste.
