Hi Dalibor, Welcome! If you are interested in building your own wind generator, there are many examples from very simple to more complex, depending on your skill level. The Otherpower link at the top of this page will bring up a few examples. There is a link that says wind (in a box) at the bottom of that page with others. Many people here also have shared their personal experiences during construction. Hope you can get the information you need. Again, welcome! Gary D.
