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

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".

[knoxarama]

er, ok. don't see why exactly but...

Because if you can't spell electricity, I'm not going to take your advice on building a wind turbine.

[knoxarama]

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]

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]

honestly who cares about spelling, It doesnt matter. as long as you can read it its fine.

[knoxarama]

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]

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

Go read "How to write a great instructable."

[FuzzeeDee]

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 2¢, Fuzzee Dee

[ajparag]

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]

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]

yes, and this is one of them. now.

[lemonie]

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

[knoxarama]

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]

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.

L

[frollard]

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

[knoxarama]

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]

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

[knoxarama]

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

[frollard]

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

[lemonie]

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

[knoxarama]

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

[frollard]

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]

. It will work if you hook it up to an HHO generator. <snicker>

[frollard]

That sounds exciting!

[Scott_Tx]

Ha. Just take a normal fan, plug it in and set it in the wind. It'll run your meter backwards! :P

[JakeTobak]

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.
