Picture of Model Wind Turbine :: KidWind Project
This tutorial by KidWind teaches you how to make an electricity-producing model wind turbine with PVC pipe, balsa wood, a generator, and a few special parts.

Students, teachers, and hobbyists love using these turbines to learn and teach about wind energy science and technology.

Step 1: Wind Turbine Basics

Wind Turbines harness the power of the wind to produce electricity. Today turbine production is rapidly expanding all over the United States and the world.

To learn more about wind energy, head to the KidWind website

This instructable will help you learn about wind turbines through a hands-on project.

Before we get started, run your mouse over the highlighted boxes on the picture of the turbine. This will help you understand the basic anatomy of a wind turbine.

Step 2: Materials Needed

Picture of Materials Needed
Hardware Store Parts

5X - 1" PVC 90 Degree Fittings
3X - 1" PVC T Fitting
1X - 1" PVC Coupler
6X - 6" Lengths of 1" PVC Pipe
1X - 24" Length of 1" PVC Pipe
1X - 2" Length of 1" PVC Pipe
2X - Alligator Clips
At least 3X - 15-18" Sheets of balsa wood (You can also use pie plates, index cards, or paper plates)

Special Parts (might want to check out KidWind website for these)

1X - Wind Turbine Generator (Small DC motor...many DC motors at hobby shops and hardware stores do not work well for generating measurable voltage at low RPMs)
4ft - 22 Gauge Hook Up Wire
1X - Crimping Hub (this is a special part sold by KidWind, but you can also use a tinker toy hub.)
At least 6X - 1/4' Diameter Poplar Dowels

Tools and Extra Materials Needed

Wire Strippers
Duct Tape
Glue
Drill

Other considerations

To test the power of your wind turbine, consider:

A Multimeter
Christmas LED Bulbs

You will need a fan or a wind source to make your wind turbine run. Head here for fan recommendations.

i need to glow an led which capacity of motor i should use here please specify, i had 12v gearless dc motor it doesnt works for the wind speed ,please specify
kidwindrob (author)  ramki2332 years ago
Hi ramki. It's tricky. You have to find a generator that works well at low RPM. Sometimes RadioShack has good ones. The generators we use at KidWind are good as well. While we don't want to use Instructables to push our products too hard, we do offer a good generator.

Can anyone please like give me a copy of the entire thing in .pdf form. i really dont wanna pay for a membership cuz im a broke high school student. Please?

You can download all of our PDFs on our website: http://learn.kidwind.org/teach/pdfs. Look for the Basic Turbine Plus manual.

this is really a great design of the most efficient & nano model of a wind power energy ............but the wind should be strong
Blade balance is important if not critical - EASY to fix. small dabs of glue, epoxy, tape or whatever till the blades spin freely and do not stop at the same place

How many volts is the generator?
kidwindrob (author)  Untitled274 years ago
The generator we use produces about 2.5 volts with a very good blade configuration. Generally this non-geared turbine produces between 0.5 - 2.5 volts.

HI does the multimeter come with this?
kidwindrob (author)  DeanC9935 years ago
If you are referring to the Basic Turbine kit that we offer on our website, yes, KidWind offers the Basic Turbine full kit, which comes with a multimeter. Basic Turbine
How exactly do you attach the blades to the motor without welding or anything?
kidwindrob (author)  downwithwikihow5 years ago
To attach blades to the motor, we use a special crimping hub that fits on to the driveshaft of the motor, and then fits 1/4" dowels around the perimeter of the hub. You can duct tape or hot glue blades to the dowels. You can also use a tinker toy hub. I suggest you look at these links. 1. Building Classroom Wind Turbines 2. Tinkertoy Model 3. Crimping Hub

Let me know if you have any other questions.

Thanks!

anyone else have a issue printing out pdf. it reads perfect then prints jsajfdajfjdfjefjiewfckeq23032r00iq-weidw-qdq

Yep, I think it's some of the java and flash used on the site that mucks with the PDF-printing. However, If you look in the list at the top after the last step there's a PDF-for download. Before that was implemented I used to get the print-friendly version or turn off flash and java.
I was searching for something to bring into my class to teach about wind and other renewable energy technologies. This Turbine is great for blade design, testing theories and introducing wind technology to groups. I am sure that many kids will be winning their science fairs with this little bad boy. KidWind Site has a lot of info on it as well.
