Look on e-bay for a Wind Turbine Alternator Generator or go to a junk yard and get an upgrade kit for it.A solenoid is not going to work.

Hi,I'm building my own wind turbine and need to know more about what type of alternator to use. Baring in mind that I'm a student and poor, so if possible could you recommend a cheap alternator.Would a solenoid work to generate a voltage?Thanks for any tips!

some environmentalists think that birds would get killed by them. I wish we'd all use at least one of these in our houses though. I'm designing a wind turbine at the moment for domestic use.

Why don't aren't we just filling up the american plains with these things?!?!

That $2 million is an old figure, remember--ask your local Vestas dealer for more current info.The St. Olaf figures come straight from the head of plant services at the school. The school had built their own power plant in the 1930s and had installed a 440v 3-phase loop they could now hook into their windmill. So St. Olaf never sells its power--they substitute it for power they would otherwise buy. And that's where they get their figures.St. Olaf LOVES its wind turbine.

I was amazed as to the scale of the turbine. It's huge! I just have a question, seems $2,000,000.00 is not a lot for a project of this size, but are you sure that it actually saved the school $300,000.00 the first year? If that's the case, then this is a gold mine. Also, in comparison, what is the ratio of homes powered by this one turbine (if you know) I'm very interested in this due to the potential of property I have in California that's been preposed for such use. I thank you.

Thanks for posting. I enjoyed your video. They sure look huge when up close like that. Looks like it was a very long day!

The blade do flex a bit. That is why the nacelle has a nose-up attitude. But mostly it is optics fooling us.This Vestas v82 cost about $2 million when it was erected. This includes the parts of the construction I captured on video plus the foundation (a BIG project) and the hook-up to the grid. To give you an idea of why everyone now wants to build wind turbines, this Vestas saved St. Olaf College over $300,000 the first year.

I agree-he's exhausted. Two questions: are those blades actually flexing a little, or is that an optical illusion? And how much does one of these behemoths COST?? I suppose that's relative to local energy prices, but I'm curious.

Well, the primary goal is to capture the energy of the wind. Those other goals may be wonderful, but if the wind turbines such thinking produces don't work very well, all those other goals fail too.As for these turbines killing birds--that lie has been discredited LONG ago. (In fact, the big turbines are MUCH less dangerous to birds because they turn so slowly.) I am sorry you still believe it.If you think that little wind turbines are better--please build one that actually works.
