# 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

Sorry, I had to exit as soon as I saw "electricty".

er, ok. don't see why exactly but...
A good name in reply to knoxarama4 years ago
Because if you can't spell electricity, I'm not going to take your advice on building a wind turbine.
knoxarama (author) in reply to A good name4 years ago
its just spelling. i could if i went slower. but i don't, and i won't change anything. this is not grammar school, the point is to get people to know this stuff, not for them to read and say "mmm, this spelling is exceptional!" if you are this picky, than good luck on most of these sites.
A good name in reply to knoxarama4 years ago
I'm about to tell you all the things wrong with that sentence: It's just spelling? Generally if you want to get any respect on Instructables, it helps to spell properly. Look at featured instructables. They have proper spelling. How do you mean "most of these sites" Mreh... this fight isn't even worth it.
Guitarmanandy in reply to A good name2 years ago
honestly who cares about spelling, It doesnt matter. as long as you can read it its fine.
knoxarama (author) in reply to A good name4 years ago
and I won't argue with someone as picky as you. those Instructables are not featured for spelling. I can guarantee you that they would be featured regardless of spelling. Instructables are for instructions, and anyone with intelligence can deciefer misspelled words. don't mean to get all worked up, I'm just tired of people complaining about small details that make no difference.

Is this a permanent magnet motor? From what I understand, if it comes from your basic fan you plug into the wall, it is an electromagnet and therefore without electricity on the outer coils, you cannot generate electricity from the inner coils. Someone please correct me if I am wrong, because I just threw away 2-3 perfectly good motors because there were no magnets.
knoxarama (author) in reply to mrbybee4 years ago
the motor i used had no magnet. instead, you have to excite your motor. to do this, plug it in and turn it on for a while. the electricity running through the coils excites it. then, start to rotate it. the excited coils will make up for no magnet. if you don't want to keep exciting it, you could replace the rotar with a magnet

Who appointed you the spelling and/or grammar police? I would think your energy would be better spent experimenting rather than jumping on people for something that has no bearing on the project under discussion. Good grief, get a life. Just my 2Â¢, Fuzzee Dee

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?
gantsa says: 4 years ago
Very good invention. There is a very good also here.

Isnt it unbelievable!! i mean the nature of the 'stupids'. I laugh a lot, great job guys

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.
knoxarama (author) in reply to Kiteman4 years ago
yes, and this is one of them. now.

You're using this as a door-stop? Come on, finish the job-off properly... L
knoxarama (author) in reply to lemonie4 years ago
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?
lemonie in reply to knoxarama4 years ago
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.

correct me if I'm wrong, but turning an AC induction motor won't generate electricity - there is no permanent magnet.
knoxarama (author) in reply to frollard4 years ago
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.
lemonie in reply to frollard4 years ago
You'd need an exciting power supply, or to make it self-exciting. This doesn't look completely finished to me. L
knoxarama (author) in reply to lemonie4 years ago
power supply? it is the power supply, or am i missing what you're saying?
frollard in reply to lemonie4 years ago
I never thought of that - so you apply x power and hopefully get x++ power out? neat...
lemonie in reply to frollard4 years ago
I don't know whether my sarcasm detector is faulty or not, but self-exciting alternators do exist. L
knoxarama (author) in reply to lemonie4 years ago
i've heard that it stays excited for a while after a current is run through it once.
frollard in reply to lemonie4 years ago
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.
NachoMahma in reply to frollard4 years ago
. It will work if you hook it up to an HHO generator. <snicker>
frollard in reply to NachoMahma4 years ago
That sounds exciting!
Scott_Tx says: 4 years ago
Ha. Just take a normal fan, plug it in and set it in the wind. It'll run your meter backwards! :P
JakeTobak says: 4 years ago
Have you tried this yet? I don't really see it working, but maybe I'm just not understanding what you're trying to do.
