Seeking advice - DIY wind power generation

Greetings. Iím seeking advice regarding wind power generation. I want to learn as much as I can, including understanding the physics behind turbine design, motors, etc. I want to understand the theory as well as the practical application. Iím also particularly curious about building wind power generators out of old junk, as opposed to spending thousands of dollars, which frankly I donít have. Every day a million tons of old motors and techno-trash is generated in the U.S. Surely I could take some of that junk and make it work for me. Right?

If anyone here has knowledge of this subject, I would be grateful if you can answer a few questions for me. I also have a vague idea for an experimental system on which I would welcome any input/suggestions. I am fairly ignorant at present. I studied quite a bit of chemistry in school, but very little physics Iím afraid. I need to remedy that.


1. Can you recommend any good books?

2. Can you point me to any info on the Web (or elsewhere) about successful wind generator projects made from free/cheap old junk?(There are tons of videos on YouTube of folks building wind turbines, but in most cases it isnít clear whether they have ever actually put them to use and harvested real energy from them.)

3. When scavenging old motors to experiment with, what should I be looking for, and what kind of devices are likely to yield useful motors?

4. Is it possible to wire several homemade wind generators in series and collectively harvest their output from a single line? Or do they each require a separate line? And if so, does it matter if they have differing outputs?

Hereís my idea:

Suppose I have a fence, 40 feet square, with 16 fence posts spaced 10 feet apart. Why not take advantage of the strength of the posts, and mount a homebrew wind turbine/generator on each fence post, for a total of 16 generators? Rather than erecting a huge tower, and spending a fortune on a single highly productive generator, I would employ 16 makeshift devices made from old scrap junk. Each one would be a small unit, and probably none of them is bound to be very efficient or productive, but there are so many of them that perhaps one could achieve a decent output? Is this a crazy idea? One could even paint the turbines and make the whole thing look like an outdoor art project.(Yes, Iím a little kooky.)

I would appreciate any info or advice that might get me going in the right direction.

Thank s in advance,


PS- Sorry so long-winded.(pun is incidental)
