Hi Leslie, My view is that the messy and graceless stage is a good time to be quiet, not a time to be bragging or promoting. We're trying to build an industry,...
It turns out that Brace Research Institute tested an Andreau turbine that was much smaller than the St. Albans prototype. What's even more encouraging is that...

The same thought must have occurred to many people. I have some calculations that I did in '96 before moving to the Philippines. I worked out the maximum...
Dear all, I have seen anemometer at the rear end of the hub on a mega-size turbine. The wind is affected by the rotation of the blades. How accurate is that ...

Dear all, Would anyone please give me a hint where to get the month-by-month wind speed data in Europe? There is always a big debate in Taiwan that wind power...

I make Hakan words mine too. I also would like to add my 2 cents on that. I saw the CBS video and I can say that the phase one of a different aproach to...
I found a picture of the winglet (I think). http://www.windkraftwerke.de/images/2003-04-26_Die_Mettweiler_1_und_2_von_der_neuen_4_aus_gesehen.jpg I wonder why...
I differ slightly from Ian on this--I'd say that accurate information is always helpful. I'm glad to hear about your design, since I have seen it and would be...
The nacelle anemometer is used for low wind cut-in and cut-out as well as high wind cut-in and cut-out. Very accurate measurements are not needed for these...
Mike mentioned financial constraints as being the limiting factor in returning his testing operations to fully functional. He mentioned that his testing is...
Lesleigh, The issue isn't transparency - of course continuous feedback is valuable to you to improve your design and process as quickly as possible. The issue...

Ian, Who is bragging? The one who is enthusiastic and eager to tell, or the one who claim a wealth of knowledge, but only use it to squash the enthusiasm? If...
Hello Chengnon Hsu, The debate you describe is why our thinking (we live in the US Midwest) look to pair solar (and other REs) with wind - the 'high' times for...

... I agree. Too bad that we have to rehash all of these arguments every time a new design comes along. As you suggest, it is mostly because new designs are...
Hugh said; "i wonder why they didn't just make the blade a little longer" At first I thought the same thing, but then I saw the noise issue. If the blade is...

Frank and Tom, It is a lot to confirm the saying that "the more you learn, the more you know about how little you know". I am perfectly ready to accept the...
Frank, This was not the issue nor the claim, since the HAWT would not be suitable to mount at the same place as the VAWT. If we draw the mathematical ...
Dear Cyrus: The design you refer to is U.S. Patent number 4708592 issued to Krolick et al. for a "Helicoidal Structures, useful as Wind Turbines" Nice idea,...
Doug, I was looking for some feedback on a refurbished turbine produced by Wind Power Systems, rated at 30Kw, and manufactured in the mid to late 80's. Thanks...
Hakan, The infinitely less expensive comment is funny. Really. But $/kWh is far from invalid - even if one accepts that VAWT and HAWT designs are complementary...
Frank, I have large difficulties in seeing myself as a windmill lover, I am old fashion in this respect and prefer my wife. Horizontal or vertical? I find both...
