Jeraklidis,
I have read most or all of your previous posts, and had gotten the mistaken impression that you were an intelligent person. Your misguided, erroneous, xenophobic comments regarding Chinese wind turbines indicates otherwise.

No offense but you bought Chinese... with no physical braking system or electric furling system....you assumed a 15ft rotor would shutdown by shorting the phases???... people need to know BUY USA EU or JAPANESE....
You provide no first-hand evidence documenting your comments regarding Chinese products in this and subsequent postings. Have you ever owned a Chinese wind turbine?
I own an Exmork 5 kw wind turbine, and CONTRARY TO YOUR ASSERTION, it does have a six inch diameter, four inch wide drum brake, which can be activated from the ground. Exmork even provided a winch with a pawl so that you could set the brake and walk away, leaving the brake activated.
And what in blue blazes are you talking about--"electic furling system"? Nobody uses an electric furling system. You must be confusing electric furling with electric yaw control.
Oh, and by the way, the controller for the 5 kw Exmork wind turbine has a warning sign right next to the switch that shorts the phases together (the "kill switch"), saying DO NOT USE THIS SWITCH IF THE TURBINE IS RUNNING. They want you to use the friction brake to stop it, then set the kill switch to hold it if you have to release the friction brake during servicing.
Besides the 5 kw, I also have two Exmork 2 kw wind turbines that are presently flying on 56 foot, hydraullically-operated Chinese towers. They've only been flying for six weeks, but both the wind turbines and the towers are operating admirably. They start up in low winds, are very quiet, and during two thunderstorms I have seen them peg the ammeters on their controllers at above 65 amps at 56 volts, or upwards of 3600 watts. I don't know why, but they aren't much noisier in 40 knot winds than they are in 15 knot winds. Very smooth operation, no slamming around in gusty winds. Since I put them up six weeks ago, they have generated over 450 kwh of electricity. That offsets the production of about 1000 lbs of greenhouse gasses (2.2 lbs of greenhouse gasses per kwh). I realize that six weeks is a short test time, but my expectations for these machines is very high. Unbelievably, these machines only cost $575 apiece. I couldn't buy the magnets and magnet wire to build them for that price. You can see why I am incensed by people bad-mouthing Chinese wind turbines with no apparent facts or experience.

FRIENDS DON'T LET FRIENDS BUY CHINESE!!!!!!

sorry I had to say it....
Yeah, I'm sorry you had to say it too, since, again, it's pure BS. The link you provided promotes Redriven wind turbines and Hummer wind turbines, both of which are made in China. Apparently that escaped your notice.
Unfortunately, that same site also promotes Cascade Engineering products--which received VERY bad press in this very forum about a month or so ago. Those are the roof-top mounted, multibladed, ducted-fan, twin-tailed machines you see on TV in the Michigan commercials.
Next time, get your facts straight and hold back the xenophobia. A wise man once said: "It is better to remain silent and let everybody think you are a fool, than to open your mouth and remove all doubt".
poco.
