2. This actually moves air, which robs a portion of kinetic potential even before it get's to generator. There are probably few more caveats with this that I am not seeing.
3. What happens with used wind? It just get shot out of the bottom? At what velocity, website speaks nothing about safe utilization of "accelerated" wind. So if we get 30-40mph wind, what happens at the bottom?
4. What will happen when it rains? This thing will channel water flying sideways just as well as air. So not only turbines need to be waterproof, but now imagine point 3 with heavy rain.
5. Wind turbines safely stop when wind velocity gets too fast. This will be harder with this construction because wind is accelerated. If wind turbine stops and they do not close some kind of shutter - see point 3.
Note: to be fair, part of the issue could be fixed pretty easily by directing exhaust back up. This however still presents problems with water and robs yet more power of winds kinetic potential.
1. In order to drive generator there needs to be a lot of wind. According to Do The Math only small portion of US has favorable conditions for wind: http://physics.ucsd.edu/do-the-math/2011/12/wind-fights-sola...
