DIY Wind Turbine – Homemade Wind Turbine

I have been thinking to make wind turbine (a large horizontal axis one) since I first published a small wind turbine video on youtube and a blog post here a few years back. That video went viral. Then I decided to make one large functional wind turbine. The former didn’t give me even 1.5 volts.

I know building a medium sized wind turbine will take a lot of time to complete. But, It didn’t, I’ve Just finished a medium sized wind turbine with only 5 days, 2 hours per day after my regular work. By the way, Here I am going to give you an overview of my experience in making this wind turbine Project.

A propeller is the most important part of a wind turbine. The propeller is used to convert wind energy to rotational energy. This rotational energy can easily be converted to electricity by coupling it with a dynamo.

Wind turbine blade should have appropriate curvature and weight to get maximum efficiency. So, I bought 6mm thick, 8 Inch Heavy duty PVC pipe ($5). Then I used a hand grinder to cut it into wind turbine blade shape with 1:3:20 ratio.

Another important function of a wind turbine is its ability to face the wind automatically. Otherwise, it won’t be able to maximize the wind energy harvesting. This mechanism is called yaw mechanism. It works with the help of a flexible turbine base and a tail. I used a johnson wheel to make this flexible joint.The tail will help the propeller to face the wind. As a result, we will get maximum output. We can cut aluminum sheet very easily to any shape. Cut it to a proper shape.
