Saw a doco on this building on Foxtel a few days ago. It looks cool. Can only provide 15% of the buildings power but its a start.
The shape of the building actually tunnels wind from up to a 45 degree angle and accelerates it over the turbines.
Even though they addressed all the problems of the 'bridges' vibrating, and the blades snapping. It still seems a bit of a worry.
Apparently there is only about 3meters between the blades and the two towers. Also below the turbines is a shopping center.
I hope they got their calculations right
