Wind generator

I made one or two when I was 10 or so. It was simple, I used a electric generator for bike light power purposes and made a propeller of plywood. But I didn´t know how to rectify the current so the analog meter that I connected also went down to the left and it was audible. It also made a sound and it was doing that with a rate equal to the wind power. I just miss those days, yes I do.. . ......

I thought about it this evening since my mid son, aged 11 talked about the subject. He wanted to do a wind generator. I bought a pc fan 3 or 4 years ago with him at a place, but we have never used it. So, what do you think, that I should go on with this and do a wind generator. I guess so. And by the time you read this, I should have made another post about it telling that it was made. It needs some planning, paper and pen, and doing it.
