All of this sounds great but can INVELOX deliver? Researchers at The City College of New York have done fluid dynamics modeling of INVELOX and say the company’s claims stand up.
...
Martin Hansen, a wind energy expert at the Technical University of Denmark, disagrees. He says INVELOX will draw in and speed up the wind as claimed, but when the turbine is placed inside the ductwork it will create such high pressure that little additional air will be drawn into the device, making it a poor alternative to conventional turbine designs.

SheerWind completed it’s first large scale prototype earlier this month. CEO Daryoush Allaei says initial testing without the turbine resulted in a near doubling of wind speed passing through the device as predicted in prior modeling. Allaei says they will now install the turbine and begin monitoring power output."

It will be interesting to see the results.

Oh wow! Oh wow! It must be awesome, but only if it can kill birds, raise electric bills AND ruin scenic vistas with better efficiency than before.

Might be OK for little ones. Can you imagine a megawatt version? Nope.
Vertical axis is easier & cheaper for small ones, usually. Not the most efficient, but cheapest per watt.

I guess we'll see in a few months if this works as advertised or not.

"Wind Energy Expert"? Does all this hot air mean he must be a poltician?

Ducted turbines? Whatever happened to vertical helical-bladed fans?

Lots of wind coming from Illinois, but that's better than the acid rain and mercury coming from their coal fired power plants!

Lots of competition now in developing new and improved wind energy devices. Of course the Technical University of Denmark is merely defending the dominance of several Dutch manufacturers including Philips and Siemens. The new INVELOX design is a fine new choice in wind power and more will be developed.

Already is agrico since once its up, there are no raw materials costs. Life cycle costs are much lower than those for fossil fuels.
