This really interesting, the reduction of noise is a huge hump to get over for Wind Power.

The one thing I'd be interested in seeing is the effect this has on birds. A major campaign against Wind turbines is the high bird mortality rates. Altering the structure to create a more powerful wind tunnel would likely increase the rates.
