Your Questions About Wind Turbine Generators Wiki

How does spinning provide mechanical energy?

Wind turbines for example. I understand it needs a generator, but I don’t understand how it generates power into it.
I was also wondering if it worked both ways. Like if a wind turbine provided energy by spinning clockwise, could/would it (hypothetically) power the generator by spinning counterclockwise?

Horizontal WInd Turbines building Instructions?

Does anyone know a website or link that can give direct insturctions to building a Horizontal Wind Turbine? Not one of those ones the size of football fields. More like a small model. Yahoo! Answers is my last resort, and I need to type my procedure in for my 9th grade Science Long-Term project by tomorrow!!

Please! I really need help! My partners on the project basically suck…and don’t know anything.
