Optiwind Compact Accelerating Wind Turbines for Low-Wind Areas

Two days ago I wrote a post about onshore turbine installation, their efficiency, about where and how could be installed.”Onshore turbines installations in mountains or hilly regions tend to be about three kilometers or more inland from the nearest shoreline . These areas tend to be windy and are good sites for turbine installation, because a primary source of wind is caused by the convention differential heating and cooling of land and sea over the cycle of day and night.The hill or ridge causes the wind to accelerate as it is forced over it.The additional wind speeds gained in this way make large differences to the amount of energy that is produced.Wind farms or wind parks usually have many turbines can installed.Each turbine affect the wind turbine recived by the behind.Since each turbine extracts some of the energy of the wind, it is important to provide adequate spacing between turbines to avoid excess energy loss by interaction effect.” - http://www.mygreentreasure.com/2009/05/how-to-build-the-most-efficient-wind-farm/
Today I will present a concrete example of such a system that converts wind energy in electricity.Optiwind created a new type of wind system, Accelerating Compact Wind Turbine, few small turbines with five-bladed fans which can generate more electricity even in areas where wind power is very low.In these turbines the synchronous generator has a few pair of poles (small external diameter) and to generate voltages at industrial frequencies they need to be driven at high speeds.Wind small turbines range from 400 W generators for residential use to several MW machines for wind farms and offshore.
This Optiwind system is useful small areas where we don’t have too much space.(having a diameter of 6 meters).This system was adapted and released for sale in two variants: first with a capacity of 150 kW for areas where the energy costs are approximately $35.000 each year, and for $65,000/year we could use Compact Accelerating Wind turbines with 300 KW output power.

I think you may want to know that Optiwind tried to get one of these windmills (Its first one) built in Goshen, CT.
They put the residents through six months of agony before the Planning and Zoning Board declined to give them a construction permit. Voting 5 to 0 to deny their application.
The reason given for the denile was that the design was judged to adversly impact the value of property values and, because none of these has ever been built, it was felt there was no way to assess its impact on the environment.
Overall the residents thought that this design was inappropriate to their neighborhood, and thought it was extremely ugly and would spoil the viewscape.
Thought you should be aware of this before you get involved with these guys.
For the most part, I agree with what you are stating here.
