This Wind Turbine Boasts 6 Times more Power Output

I have been exposed to some information about wind power.  While on vacation last year I stayed at a lodge that was in a fight to keep their scenery free of turbines.  On the flip side I have friends who are wind farmers and I have even known a person made and installed his own wind turbine in hopes of saving on electricity only to find either not enough wind or in the lodges case they didn't like the noise. so I guess what I am trying to say is I can see the pluses and minuses of the current(No pun intended) standard.

Enter the latest idea from SheerWind.  Although, the Invelox looks a little strange the creators say that it takes up less space that a traditional wind turbine and produces much more power. Well they have my attention,  I guess the next question is how noise is it and what is the return on investment.
