Introduction: Wind Turbine

I'm very interested in freedom,  and anything you do not have to pay for.

The wind is free ,  but turbines cost a lot ,  so here is how to build a ten foot diameter wind turbine on the cheap.

Step 1: Your Tower Needs an Anchor

Do not under any circumstances dig a hole more than 3 feet deep unless you have been trained to do so.  Small hole collapses kill more people every year and if you do not know what to look for you could be taking a chance with your life.  Respect the threat and if you are unsure find some one that understands the risks and can help.  


You don't want your tower to fall over,  so you will need an anchor.  I used over a thousand pounds of concrete that I set five feet deep in the ground.

I started by digging a five foot deep hole.

Step 2: Your Turbine Needs Wind


Turbines need to be up as high as you can get them,  so to get as high as you can you will need a tower.

I made mine with 6x6's.   It's 20 feet tall.


Step 3: Turning on a Dime, or a Bicycle Down Tube


Your turbine will need to be able to turn into the wind.  Bicycle parts can take a lot of abuse,  so I used them for all my moving parts.  Here is how I used a front wheel fork down tube and bearing housing for my turbine's pivot.


Step 4: Electric Boogaloo


I've been looking into a generator for some time.  I've read in a few places that this is a really great motor to use and I found it on my first try digging at the dump : )

I'd like to wrap my own coils at some point,  but for right now this will have to do.

Step 5: The Cutting Edge of Power


I've seen many websites that show how to cut blades out of pipe,  but I had never seen anyone use thin wall 6 inch pvc used.  My blades are 4 feet and ten inches long and they are cut to hold a 45 degree pitch from the hub all the way to the tip.

I'm very happy with how they turned out  : )

Step 6: I've Got a Nose for Wind

The nose cone is really just for aesthetics.  I vacuum formed mine and my vacuum form machine's check valve had gone bad ,  so at some point I will need to make another one.  The next one will have a raised ring around it with a v shape to it,  and I'll put a v notch in each blade to hold it in place better.

Step 7: Enjoy the Freedom

Now get out there and build a wind turbine !!!!

And remember ,  Be safe ,  Have fun and go green for the green.

It does not have to cost a lot to do great things your imagination is the limit ,

    does the generator need to be right next to the turbine? could it be connected to the turbine, but on the ground? Again, thanks!

    With this design, it will be difficult. placing the generator right next to the turbine decreases the additional mechanical parts like gears you will need as opposed to if it was on the ground, adding a chain could work if your turbine has a fixed direction, but again additional parts can reduce its efficiency due to loss of energy.

    I'm soooo gonna build this (eventually). I love this project! But how can you hook this up to your home appliances? Thanks!

    good one

    but cant understand the generator

    How long was the wood?

    Could not see how you drove the generator/alternator. Belt drive? Chain drive? Surely you did not mount the propellor directly on the generator shaft, so that its bearings would take the full load. Please tell us.

    Looks good.
    My biggest concern is why are the blade set at 45 degrees? Wind turbine blades need twist with more angle at the center and less at the tip because the tips move faster. Your blade tips and roots will be fighting each other and it will not be very efficient.

    what kind/ size / make is the generator. I rent an industrial building downtown and have been thinking about setting a turbine up on the roof. I've seen an electric connection that allowed rotation without cords winding up, two rings one with two contact rings and the other with two sprung "brushes" if you will. Maybe that connection can't conduct the amount of current needed?

    If your really serious the only way to go is to wrap your own coils, every place I've seen where people are getting really good amounts of electricity , they wrapped their own coils. I believe there is a tutorial over at otherpower.com and I think there is an instructable as well.

    I think there is also a tutorial for building your own slip ring (electric connection that allowed rotation without cords winding up).

    Go for it !!!
