Dunno if this is appropriate, but where I live in western NY, the stated wind speed average is 13 mph. The commerical wind farm people have just erected 67 GE...
Wife bought me a weather station, not hooked to computer from a place called "wind and weather", I think they also have other models that do use computer. ...
Why i havent seen conning control systems in small wind turbines? Is this mechanism, that allows the blades to fold and form a cone in high winds, reducing...
hello all I was watching Danish television and the turbine that crashed was 20 years old.. maybe there also had been some problems with maintainace , so think...
... Correction - we had VERY!! strong winds I can tell you. An old Nordtank turbine - Nordtank taken over by Micon taken over by Vestas performing a ...
The wind industry means a risky race if you want to be a big company and take the best piece of the cake...Two of the biggest manufacturers in the world had to...
Multi-rotor turbines have no tower strike issues, no tower shadow issues, and no precession issues, no issues with turbulance or fast direction changes, and no...
... I may have been playing the devil's advocate or some such caper. I admit that I have not yet personally been converted to the VAWT persuasion but was...
In Europe, that diversion load could be a Windyboy 1100 LV inverter which stands for "low voltage" - this means a person with a 48-Volt battery-charging...
Raul, When you're going to post such hit pieces, you should really include some background for the Anglophone readers of this list serve. Most on this list...
Some people read about stuff all day. Some people talk about stuff all day. Some people write about stuff all day. But some people have to actually DO the...
Hi Robert, I agree with your analysis, the "in plane" vibrations and deflections of the blades, shouldn't be disregarded, specially when dealing with heavy...

A catastrophic tower strike like that could never happen with a Superturbine since the rotors are away from the tower. Doug S. http://www.dualrotor.com P.S....
... For low speed you do not really need an airfoil that much. Lift/drag ratio is not that important at low speed. A curved plate works pretty well. Lift is...
Very good thank you. Maybe you can help us out with some additional information which I have yet to come across. We would like to know how to determine how to...
... I hope that nobody actually thought I was serious :-) That turbine failed because it ran away. By the way my name is spelled with 2 ts. Vawts are an...
Forgive the redundancy factor but, many of us in the small turbine world actually PREFER low speed rotors over high, and have spent plenty of time working to...
Great Matt. Why don't you write up an engineering paper all about you efforts to slow wind turbines and use larger alternators. I guess when you get right down...

Doug, I doubt that anyone has a "problem" with your approach, it's your deal - we get it. I also don't see why you take every comment that might go contrary...
Great points all, David! AmpAir and Kestrel (excellent machines all) both have individual power curves for each voltage winding, for every model they produce....
Hi Steve, I have spoken with the manufacturer of these machines several times, but have never received any adequate answers to the majority of my questions....
