Can I use electric fan motors as generator?
Yes but you won’t get much current out of it. The wind turbines that you see on top of high poles are huge. They don’t look it from the ground but you could walk around inside them. Also, in order to be practical, you need to hook the generator up to a storage device (batteries) in order to store the electricity (otherwise, you’ll only get current when the wind is blowing). So, it’s not really practical but you should try just for the knowledge of it. Be careful though, you will be working with high voltage and you need to take precautions. The link below is to a wikipedia article on wind power that’s pretty good. http://en.wikipedia.
