Today I learned about the
Bahrain World Trade Center. It's the second-tallest building in Bahrain, and the first skyscraper in the world to include wind turbines in the structure of the building.
The towers are shaped like sails and were wind-tunnel designed so that wind coming from as much as a 45 degree angle (to the face of the building and blades) is caught by the building and funneled so that it remains straight-on to the turbine blades.
Those turbines were brought online on this date in 2008.
