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.

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

NHLiveFree Champion Author New Hampshire Posts:11,306 Points:1,651,045 Joined:Jun 2008	Message Posted: Dec 5, 2012 12:42:56 AM Ignore NHLiveFree Report Abuse 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.
