## Introduction: Simple Wind Turbine

Knox co. presents the next energy source, the wind turbine. But what makes this different? This instructable will also show you how to make a hanger so it can rotate into the wind, maximizing efficiency.

## Step 1: Materials and Tools

You need:
A long, thin piece of wood
a working fan
a long, thin metal tube
twine, rope or string

tools:
a screw driver
scizors
a drill

## Step 2: Stripping the Shell

Noted, you can skip this step. This is merely to allow for maintanence convienence.

Unsrew the shell and take the knobs off. Unscrew the blade, take the shell off, and put the blade back on. This should expose the circuits under.

## Step 3: The Rod

Get your pole and drill two holes at the top straight across from eachother.

## Step 4: Support Beam

Take your piece of wood and your pole. Line the pole up at the center and mark two points at either end of the pol at about middle depth.

## Step 5:

Take some twine and run it through the holes in the pole and the wood and tie knots at the ends.

## Step 6: Putting It Together (update)

Now make another length of twine and tie it to the pertruding part of the fan (in my case a metal piece). Drill another hole in the beam in the center of the first two, and slightly lower. Run the piece of twine up the pole and through the center hole, and tie a knot so the pertruding piece is inside the pole, and it dangles there. Now attach the wood to a forked branch in a tree or something, and run wire down from it. You could use electromagnetic induction to reduce wire use, but it also reduces voltage, so it isn't recomended. But this will follow the wind, and now you can plug something into it without plugging it into the wall.

update: you should attach a group of running capacitors to the prongs. also, i did the math and you should get it to spin about 23 times a second. then you sould get about 120v or so.

could any one please tell me about a turbine that will generate electricity with out being to big. thnx

good job!
can you also post a video or picture showing the working model? i mean can u post a video showing how it generates electricity?

correct me if I'm wrong, but turning an AC induction motor won't generate electricity - there is no permanent magnet.

You'd need an exciting power supply, or to make it self-exciting. This doesn't look completely finished to me. L

I never thought of that - so you apply x power and hopefully get x++ power out? neat...

I don't know whether my sarcasm detector is faulty or not, but self-exciting alternators do exist. L

i've heard that it stays excited for a while after a current is run through it once.

the sarcasm was on the hho reply - that was literally the use electricity + torque to make more electricity...I never would have thought of that.

power supply? it is the power supply, or am i missing what you're saying?

i was stuck on that too, but in testing i did get a current. Of course, if it doesn't work for you, maybe the fan was built differently (i.e, mine might be a universal motor, your might not) you can always replace the generator piece.

This is not a good instructable at all. Sorry.

There are already a large number of turbines that use the "wind vane" effect to naturally line up with the wind.

You're using this as a door-stop? Come on, finish the job-off properly... L

i'm still having trouble finding a place to hang it. I tried the forkin a tree, and that didn't go well, so there was the only place i could put it to get a full view of it. unless you mean "...finish the job off properly..." in a mafia sense, who should i kill with it?

Ha, yes I can imagine some guy in a suit & hat marching into a bar with this and letting rip... I meant that it would be good to see this outside and with the electrical connections completed. With reference to Frollard's comment, generators require a magnetic field, for common DC motors/generators there are permanent magnets. For a generator without permanent magnets you need an electromagnet, which you produce by "exciting" the stator-coils by feeding some current through them.
