Architecturally-driven wind power looks interesting

Can buildings be designed to harness wind power?

"Taking architecture, and wind power, to new heights, developers of the Bahrain World Trade Center in Manama, Bahrain, flipped the switch to start three huge turbines set between two towers — a first glimpse of technology that they hope will power up to 15 percent of the center."

Unfortunately, the cost of adding wind power to this building project has not been provided, but it would be interesting to know how long it will take this project to recover its wind power development costs. Because these buildings can act as a wind funnel, the design of the building increases the efficiency of this system, of wind power.

Still, is it cost effective?
