That is the big question of course. I doubt that Navitron, or this other outfit over here, is prefacing their marketing attempts with Caveat Emptor. :-) ...
Greetings to you all. Let me crawl out of my cave for a while and spout off about lightning and wind towers. I have experience with numerous small grid...
Lightning. Yes, a very unpredictable item ! But,,,in the Canadian Electrical Code there are guide lines for tower grounding. Many sites on the internet...
My understanding is that for comparison (effeciency) purposes, Horizontal Axis Turbines are measured by the sweep (or area) that the blades cover....Is this...
Claus, Just to clarify something here, I have not seen any Indian turbines in this class that are sold in USA. Sulzon (Indian) models are much larger capacity...

Hi Mandarin I think!! ;D Wish I was as smart as you well sure I'll give it a go, not easy trying to gain an education thanks Stephen ... ...
Caution: Not all machines that come from China are certifiable to be from China. Meaning, some equipments made by known brands from China are lumped with...
Use the entire plan form, or maximum face to the wind, to calculate the surface area of the rotor , so for your straight blade VAWT it is 16 sq ft. it is...

Hi Nando Well shorting out your generator is normally how electromagnetic braking is accomplished - the fastest way to shut down your turbine as far as I know....
"William" Do you make or supply blades? If you can copy those, I am always on the lookout for cheap blades. Our turbines use conventional blades so we are...
Bruce, I'm glad for the heads up on the lightning. I was about to install a weather station/anemometer sending unit about 8 feet below my wind gen. I probably...
A couple of months ago this lists presented a couple of messages on an Indian manufacturerdoing pretty much copying of small scale US turbines, where are they...
Not so smart, just old! :-) I'm sure you'll have more fun learning about your wind system than you would going back to university, and it's so much cheaper! ...
That would be a bit under 0.7 meters I believe. I had a big "discussion" with PacWind about this just yesterday. They think I just don't understand why their...
Hi Matt you know i was only having a little fun with nando, since he enjoys that SMA is aware of our product, says they think they can sell a few for us right...
We make Neo magnets used in Generator,we always do some exprements according to customers' requirements when we making magnets,anybody who knows about the PCT...

Don: I do not remember, if I sure, but in the past, I think I described a T filter to protect the equipment from lightning, which is quite effective. The T...

Doug, Not speaking for SMA here, but I seriously doubt that they would be too thrilled about any non-SMA devices being put inside their listed enclosure. I bet...

I've posted several reviews of new books on both large and small wind turbines at the links below. * ...
Donald, I hope you have considered galvanic action and the possible corrosion problem you'll have with the copper on steel. I can't remember which one will...
We're actually talking about the effective area of a Savonius, not the total face area. Only 1/2 the frontal area is able to contribute to energy production at...
Gentlemen: Nickel Iron batteries = NIFe= Ferronickel batteries. I would like to know what NiFe battery sources are available ( who make them) and their cost...
Doug, The sad fact is that shorting the generator is indeed how electromagnetic braking happens. It may be the fastest way to shut down a turbine that's...
Matt, Ken is right--of course he's my source when I want to know something about small wind. It's total frontal area, not 1/2 as you suggest. That's why drag ...
