If you are in charge of any alleged research program that is supposedly searching for an improvement in wind energy, just ask yourself, if such a solution...
Hello, To me, full scale on site test is good for verification of design for the specific site. The testing possibility are limited by weather and unrepeatable...
The analogy of rotor aerodynamics have always been a reference point in the theoretical analysis of propeller type rotors whether for propulsion or wind energy...

Dear Mel: I have no quarrel with real science, what I point out is that a creeping bureaucracy has taken the name "science" without any responsibility to see...
Oh my goodness ! Where can I get one of THESE VAWTs ?? 10 MW of "energy" ! See, it says right here in this news flash that VAWTs are better than HAWTs and...
hey Mel I was thinking some more about this and it is a good question you ask. I think it comes down to this: You say scientists are those seeking the truth,...
Right on - but the perpetual motion machine ('zero energy point' what have you) crew are what are called 'true-believers' - nothing will deter them from...

Mike, Wind speed has a very large impact on power production. Of course, agreed.But turbulence is also important. I think the major difference between a power...
The big 3 MW Vestas 90 meter turbines produce more than 1 kw per *inch* of one blade near their tips at rated power. (Just divide the 3 MWs by the total...
I am interrested in becoming a representative for my local area in SW Fla. Are there any products that may be utilized by the individual home owner with...
Small wind, just for comparison, in penciling this out, does not come anywhere near. While the big turbines can do up to one kilowatt per inch of blade length...
Mike K, In my opinion a power curve is a power curve. You follow a protocol and get a curve. If you do it at a low wind site you don't get points up to, say,...
Water is already burned, as it is dihydrogen oxide. It's the "unburning" of it that gets expensive. Frank _____ From: awea-wind-home@yahoogroups.com...
Mine too! A quick search will turn up nothing at all about these turbines or either one of the companies involved. To produce 10 mW the rotor (if it even has...
Raul, With all respect - you seem to have propulsion and extraction technologies all mixed up in the same bag. The aerofoils are not the same at all - one...
Hi Matt, You have not read carefully what I said and what I implyed. I pointed out "Assuming the opposite camber of the blades , of course". That is enough for...

You said it. Up-front rebates do nothing to promote energy production, and might even have the opposite effect. My feeling is that, providing a turbine meets...
Frank, Bats don't "look" at anything, remember? Their sonar tends to be focused in a range that includes recognition of things that occur in nature, not ones...
Hello, I'm brand new to the group and would like your thoughts on the turbines at www.racecom.com They are vertical and maglev. He uses wind directors to...
I have been asked to wind a SuperTwin to replace a "high voltage" version of the old Whisper 175 turbine, that feeds "wild 3-phase" power into a step-down...
Hi Charles, About the pros and contras of Wind tunnel vs. Truck tests, it is worth to mention the influence of the truck body in accelerating and deviating the...

Hi Raoul, I agree with most of what you are saying. Only one remark about the open throat wind tunnels : the flow around the model is allowed to expand, yes....
Hi Ian, I think yours is an excellent idea. If an owner wants to install a turbine even though the site is not ideal, the owner should be able to get some...
Raul: It never hurts to re-read Hugh's Books. Mel: It never hurts to read Hugh's books. "Windpower Workshop" by Hugh Piggott - Doug S. ... point in the...
Except possibly in immediate proximity to the ground, the atmosphere is LESS turbulent than a wind tunnel. In the late 50's a blimp was even configured as a...
