Just when you thought the tide was turning, it turns back on opponents:
It works in the same way that squeezing a hosepipe makes the water come out of it faster. Bernoulli’s principle means that by funnelling wind into a smaller and smaller space, the speed that it travels will increase significantly — about 70 percent, allowing for a very small multi-axis turbine system to be positioned in the middle.
Another benefit of this system is that the amplification means it can be used in low wind speed areas that wouldn’t be suitable for regular turbines. Plus, the height of the structure can be kept below 25 metres. The system is scalable from ten-kilowatt home or farm installations to huge, multi-megawatt power stations.

Considering the amount of public opposition to standard design wind turbines and the concerns they will permanently damage the landscape, I can only the problem becoming a whole lot worse with this design.
