Architect David Fisher has proposed a plan for rotating towers that produce all of their own energy through wind power. The Rotating Tower would be built by stacking platters on a central concrete core with wind turbines located between each of them. Each floor will rotate 360 degrees about once every 90 minutes; as the floors will rotate independently, they will create a constantly changing silhouette in the sky. Inside the concrete core will be elevators, emergency stairs and lobbies. The Rotating Tower will be built in Dubai in the next six months.
