Small Wind Power

I might possibly be building a wind power generator thing. Here are some pictures of it. Nevermind I dont know how to get pictures in here. Anyway, I have been searching the internet looking for a small cheap generator that is easy to turn. The wind will not be able to turn the ultra-simple electric generator that is out there(If you do not know what I mean search it). Thank you
 
(If you do not know what I mean search it).
I searched it (ultra-simple electric generator) and got a science fair project that will turn if you blow on it. Please be more specific (url would be nice).
 
OK This is the one I was referring to -http://www.eskimo.com/~billb/amateur/coilgen.html
Could you please post the link to the one you can blow on
 
What are your requirements for the circuit? e.g. how much power do you need out of it, how large can it be, how much can you spend. . .?

Is this for a practical use or is it a demonstration or proof of concept only?

Ok the box is from sketchup. It is 1 foot x 6 inch x 6 inch(lxwxh) There is something like this if you look at just the rotor from the side: |
| with 2 lines on the sides too but, I can't draw those. I am building it for extra credit for technology class. so it does not need to be for practical use. I need enough power out of it for maybe a small lightbulb or led. It needs to accomplish this from the wind of a normal housefan. Also if you are wondering why there is a hole in the back it is so it can accept wind from both directions.

Of course the Ultra-Simple Generator can be operated with wind power. Just add a big propeller for the wind to turn.

Do you need to wind the generator yourself or could you just stick a propeller on the shaft of a small DC motor?

If you google "pico turbine" you will find a design for a small savonious generator.

**broken link removed** is a pdf describing a typical pico generator.

These types of generators can be scaled up quite easily.

Years ago, while living on a boat, we made a wind generator out of an old computer motor. The motor was surplus from the old reel to reel computers you'd see in an old James bond movie from the 60's. With a 4Ft prop hand carved out of wood, this thing would crank out 10-15A at 12V in a good breeze. The easiest by far is to find a small DC motor; it'll give you more power than anything you can build yourself out of a nail, magnets, cardboard and wire.
