http://www.vawt.tk Here we go again, building another vawt.

With this one I am hoping to get the 100 watts.

Here is how I did it.

First we need:
--5 pvc tube. size 3"X10' (hardware store)$48

--3 bike wheels. size 12" (junk yard or ask your kid to use their bikes for a minute) maybe $5

--Ametek38 volt (ebay or surplus store) $60 (a problem with ametek, it needs 500 rpm to reach 14.1volt.

--Or buy windblue alternator (ebay) $250 it will only need 200prm to reach 14.1 volt

--1 square foot 1" plywood or anything 12" diameter (laying around)

-- 3 X 2x4 X 12' studs (from lumber store)$11

I am not going to name the tools, but I used the usual tools.


Step 1: PVC Pipe

1-I cut the tubes in the middle

2-Using a template, to where I want the hole so the pipe did not travel past the rim, I simply drilled the hole (as shown in the photos)

3-I laid the 1/2 pipes down alternating ends. We all know that the pvc has one end wider than the other to be able to fit to each other (phlange)

That was it for the pvc..really ...that was.


Step 2: Bike Rims

It takes 3 to tango on this one.

1-The rims are all the same size 12"

2-I removed the spokes on one side only

3-I left the top Rim as is and used the rim's axel as a bearing

4-I left the middel one as is

5-I drilled the bottom Rim out or cut off the axel cover including one end(shown in photos)
I then placed a piece of plywood on the bottom for support and cover for the generator. To find the centre, you simply use a thread and wind it through the removed spokes, and where they meet you will see a star and in the centre of the star is your mid point.


Step 3: The Frame

1- It is a 12' high and 2' wide box.

2-I drilled a hole on the centre bottom of 2x4 for the Ametek back end little shaft to sit in (only an Ametek owner will understand this step)

3-I drilled a centre hole for the top axel to screw in, for the top section.


Step 4: PVC Blades Assembly

Before you start you need to know that the spaces between the spokes vary closer to the centre, so use the wider side of the pvc on the more loose separation between the spokes on the wheel, that is why we Alternated the pvc end...remember.

1- Slide all bike Rims in place first

2-Screw the end rims first, one PVC at a time.

3-Once you finish the end Rims, then you screw down the mid one.


Step 5: Result and on Going Testing!

After all is good and it is spinning, I realised it can only go to a max of 350RPM before it starts to bulge.

The Ametek requires 500rpm to get 14.1 Volts.

Options are to gear the Ametek or to buy a WindBlue 12 volt alternator, or for me to make a Custom biuld Alternator.

So what Option do you think is the best?..

In total it cost me $125 plus screws and my time. Really cheap.



<p>Faroun, </p><p>Question....who the heck is 'NORTHER MACJINERY WEB SITE', cannot find it anywhere. Was he talking about Northern Machinery, Or Northern Tools? Or china, perhaps? </p>
to keep the bulging from happening, try tying a string/wire around the middle of each half.
To keep it from bulging use a threaded rod from top shaft to middle to bottom and leave shafts in wheels. Also the PVC or ABS could be cut in quarters and all spokes could be left and a little slit cut made into the blades to fit in between spokes. It wants to be as lightweight and as sturdy as possible.
I see allot of PVC VAWT's with the blades crammed together like on this, I also see 55gal. drum ones that have two blades stacked up with more drums. Is one really better or are they just two different ideas.
this one has wood airfoil blades and it works on lift and rpm <br>the drum or savonius works on tork and most will not excceed 200rpm. <br> <br>lift is more effecient, but the rpm causes few issues so it has to be build well. <br> <br>sam
I liked your project kinda neatly built but I'd like you to put up an instructable for your Column - R. The one you showed up in the video below, I may wanna give it a try :)
the Column R has so much more testing. <br>i cant promise a full instructable, and i am so bussy at this time. <br>maybe in the future i will create it. <br> <br>i have about 17 vids on you tube to see the Evolution. <br> <br>regards <br> <br>sam chamas
@al_taka:<br>Looking at the photos, I'm thinking that you really cant turn the vanes any more towards the *outside* of the rim because you wouldn't have anything to attach to the rim. The way the vanes are constructed requires the orientation shown. If the builder had left a small ring at either end, that ring could be attached to the rim, allowing the vane to be rotated so that the concave face presents more 'windwardly', but this would make constructing the vanes MUCH more difficult, with little realized difference. <br><br>@Faroun: <br>Have you considered twisting the vanes along their length? As half a pipe, the vanes should have much greater flexibility around their vertical axis. You could rotate the rims w/respect to each other to twist the entire assembly. Would be interesting to see if it had any effect.<br>I like this design a lot, Nice Job!
THanks Phred, i have modified this project to resemble the v8-4&quot;. so i can adjust it back do to many hole in the vanes . in order to try your suggestion i have to start fresh. at this time i am busy with the Column-R project, it is a vawt that uses airfoil to create rotation. check it out <div class="media_embed"> <object height="385" width="480"><param name="movie" value="http://www.youtube.com/v/enn1hizKvyU?fs=1&amp;hl=en_US"><param name="allowFullScreen" value="true"><param name="allowscriptaccess" value="always"><embed allowfullscreen="true" allowscriptaccess="always" height="385" src="http://www.youtube.com/v/enn1hizKvyU?fs=1&hl=en_US" type="application/x-shockwave-flash" width="480"></embed></object></div> <br> regards sam
Great design!<br /> &nbsp;I was noticing the other day that wind gets greatly accelerated when it goes around the corner of a building, so I thought this would be the ideal place for mounting one of these turbines. How much vibration do they make? Would it cause structural problems for a building it was mounted on?<br />
not much vibration, you can always use a rubber separator where it is fasten &nbsp;to the building.<br /> <br /> sam
Not sure if someone has suggested this or not but what if you add a couple more rims to help prevent the bulging at higher RPM? Would you also get a better result using ABS instead of PVC pipe? It's been a while since I have looked but I remember the ABS being thicker and harder/ stiffer. Maybe less flex involved. Great job on the explanation, thanks!
while testing with My V10, I did try more rims, there was less bulge but not totally gone. that is why I developed the cigar shape. Not just eliminated the bulge, it also increased the rpm and blade area all at the same time. my V8-3" and v8-4" are a better design. thanks for you advice and great and helpful comment. best regards
I wonder if having the additional rims (besides the original 3) is necessary. Perhaps just having a circle of wire wrapped around the intermediate areas where it is bulging would get it under control.<br />
hi faroun and thanks for the details instructables. Just a quicjk question to be clear, your v10 is not a "version 10" being the evolution iof v8.3 and v8.4?? I'm a bit lost between all your models and as it seems you did a lot of testing, which is the more efficient one? According to this last comment v8-4 is the best. Is that right? Thanks a lot
the most efficient or the most tork is V8-4&quot;.<br/><br/>the letter &quot;V&quot; stands for the num,ber of pvc Vanes, v10 has 10 vanes at 3&quot;<br/><br/>V8-4&quot; has 8 Vanes at 4&quot;.<br/>the intersting design got the GSD at harvard attention.<br/><a rel="nofollow" href="http://www.greenenergywindturbine.com/harvard/preview.html">http://www.greenenergywindturbine.com/harvard/preview.html</a><br/><br/>regards<br/><br/>sam<br/><br/>
Thanks for sharing ! <br/>Looks like the photos on the link you give actually designed the center bulge in.<br/>I'm seriously thinking about building one but I'll build my own alternator. I have a few links on this if you haven't seen them already.<br/><a rel="nofollow" href="http://www.windstuffnow.com/main/projects.htm">http://www.windstuffnow.com/main/projects.htm</a><br/><a rel="nofollow" href="http://www.otherpower.com/wardalt.html">http://www.otherpower.com/wardalt.html</a><br/><a rel="nofollow" href="http://www.otherpower.com/wardmil.html">http://www.otherpower.com/wardmil.html</a><br/>
the link and i are the same person. i was only pointing out that one of my turbine was put on display at GSD. greenenrgywindturbine.com ,wrapwind.com, collectwind.com, windhijacker.com, smoothwind.com, fawts.com, fhawt.com, windfriction.com, wintornado.com vawt.tk all my web sites. but instructables.com is one of my favoraite sites for others to see us and our creations. i hope you are learing few things. best regards Sam, Faroun, Emagnets, Vawt ....many names same ideas to share.
or even just shortening the entire device and increase the surface area of your turbines radially (try using aluminum)
The BEST way is to make your own alternator with an increased diameter of the stator/rotor with more number of magnets and use thinner coil (about 24AWG) with more windings so it will produce higher voltage in lower RPM. and connect them in parallel for more amperage.
hey Faroun i understand u have i license, im a 13 year old lving in New Jersey i wanted to know if i could use ur V10 in my science project on energy, ofcourse i will have a link going&nbsp; back to u all i,m asking for is your permission to use ur V10 for my project
I am happy to be part of your science project.<br /> you have my blessing and permission.<br /> be carefull when handling power tools, i am sure an adult will giude you through your project.<br /> Exccellent Choice and good luck.<br /> <br /> regards<br /> <br />
Thank you very much, ill send you a copy of my report, and a video of the day we finish our projects in action, so you can see this porject in action.
<p><strong>Although i am not sure about the Alternator or the volt, im sorry but if i cant get my hands on them i may have to do something different, even though ill try my best to make it</strong></p>
you should be able to find small pmg in old printers.
I was thinking... would it be possible to put it on it's side in a river or something, I just heard that water is denser, and so has more energy than, air do you think it would work? p.s.- my idea - pretend it's copyrighted please thnx
sure it will work, but there are better and more effecient turbines for that type of energy collecting method. my turbine is meant for wind. regards
hi there guys, i have made a new wind turbine style and call it The "FAWT Silo" (fixed axis wind turbine Silo) maybe later i can do an instructable on it, but for now you can visit my site at www.wrapwind.com to see how i did it. regards
I'm laying out my vane design right now and I came across this step above. What was the reason that you have the open end of the vanes facing mostly into the turbine instead of having the open end facing the incoming air? Also, I chose an odd number of vanes so birds will see very little light through the spinning turbine.limiting their kamikaze effect. Your advice on wasted air inside turbine made me think to use 4 to 6 inch pvc vanes. Thanks for your advice Al
no particular reason for the Vanes layout. you can try them more in the open position. regards
Did you cut this with a power tool? Is there a risk of the PVC shattering?
You can also put the blade on backwards if you use a circular saw. I've cut a lot in construction in my day and that way works very well, even in cold weather. :)
i used a bandsaw with a fine teeth blade, you have to be patient while cutting.
Could one put a DC motor on the bottom of the turbine and wire it the a battery holder to charge batteries?
yes, that is the idea here. regards
Cool! I've heard that there is a chip that you put in a home-made charging cuircit the keep it from overchargering the batteries/electronic and frying it. Is this true and were can I find one?
yep, they call the gizma a "charge controller". if you go to my site i think i have a link there. www.greengoogle.ca regards
well after seeing so much of these wind generators i am thinking that if your getting 350rpm on the ground try your roof if you have a flat surface and mount there also i seen many different designs and the best ones seem to channel the wind into the wind Turbine you have a very nice lay out but i am sure you would get even better performance by haveing still fins that will channel the wind into your turbine also i am going to start mine and because i want it to run some things in the house such as lights and that best to build your own alternator its not hard and use really strong maganets but i really like your design its a easy contruction and looks really good as well Great job.
how would I go about connecting something such as this to my home?
the V10 produces little power compared to other tirbines. this turbine needs to be connected to a battery bank to store the energy created, after the batteries are nice and full then you can supply you appliances using an inverter. regards
ok thanks for the info! =)<br/>
What can this generator power? I'm new to this and don't understand my electric needs yet.
the scale that this turbine is built at , it can only produce 100 at 30 to 35 kmh wind. not much, but if you store this power then it can be very usfull at a cotage,garage or remote well and so on. regards
I know how to build a permanent magnet generator but not one small and efficient enough for this type of turbine, any suggestions??
i learned great deal of info when i built my pmg, but for the "V" series, i used ametek because it is much less to buy. i would suggest to buy wind blue or presto wind for this kind of projects. regards
Vawt, Just finishing up my alternator for my vawt, I made the alternator with the 12 magnet and 9 coils, the magnets mounted on steel rotors. i used a craftsmen 19.5 battary drill. At about 100 rpm I was getting about 20 volts and about 7 amps when I shorted out the alternator wires. I think that is pretty good.And better then I figured. The coils are made of no. 14 magnet wire and each coil has 200 windings. The vawt is a 3 blade and each blade is about 22 inches wide and about 7 foot 6 inches tall. I hope to put it up this weekend to see how it will work out. I built my own 3 pahse rectifier and next I have to build the voltage controler. Alot of work for the vawt's
great work, are you planing to post the how to here?, thanks
Faroun,Ill post it ,I just have some small things to do,make the holder that holds the stator a bit stronger,I only made it out of 1inch angle iron.
here is another site.<br/><a rel="nofollow" href="http://www.fairradio.com/catalog.php?mode=viewitem&amp;item=4658">http://www.fairradio.com/catalog.php?mode=viewitem&amp;item=4658</a><br/><br/>good luck.<br/>
How much does it cost? It didn't say on the page.
