Is it possible to use a CPU fan to generate electricity to power an incandescent electric bulb?

Okay, I have to make a  model of hydroelectric power generator. I know that a DC Motor can produce only AC current when its rotated. But as far as I know AC current can power an incandescent electric bulb. So,Is it possible to use a CPU fan to generate electricity to power an incandescent electric bulb?

I had one of those CPU case fans with the LED lights on it.It was pretty dusty so I took at blew it off with my air compressor. The lights came on. Keep in mind the RPMs have to be pretty high to do that

You may be able to do it with the Incandescent light from a scanner or photocopier.

See my Instructable:

They only run 10 ma as in the Pic however you may need to rewire and use two fans in series if you can’t find a scanner light that runs on 12 volts.

I would like to know the way or the method you extract energy from the cpu fan... like what are the components required and how do you set that up... I'm very interested in it and would like to know to the soonest...

Emm. No, DC motors can generate DC !

To get "12V" out of a 12V fan, you'd have to spin at the same speed it would run at as a fan.
