Windmill Building Information

Would you like to make a windmill?

Windmills have been around for centuries. The concept of a windmill is to capture the winds energy to spin the blades, converting wind energy into mechanical force. This mechanical force can be used to turn a generator and produce electricity. Originally they were used for pumping water or grains. Modern versions typically use high tech, lightweight components such as carbon fiber in their construction. You don’t have to use these costly materials. Windmill building can be done by a skilled, do it yourself type of person, for a very affordable price. With simple hand tools, access to a hardware store, and basic construction ability, you can make your own windmill.

The primary goal of any windmill is to maximize the conversion of wind energy into mechanical energy. It shouldbe tall enough to get above trees and other buildings. First check out your local building laws before starting a windmill building project. They may limit the height or location of the windmill. The blades need to be shaped so that they capture the wind. They should be made from lightweight wood or plastic and rotate with ease Think of an airplane propeller.

The two kinds of windmill design are horizontal axis and vertical axis. The horizontal axis ones are the most often used. Their vertically spinning blades face the wind. The downside to this design is that when the wind changes direction, the horizontal axis type won’t be very effective. The vertical axis windmill can produce wind energy from any direction. It has a vertical main shaft and its generator can be located on the ground unlike the horizontal axis. Another important windmill building step is to know the general direction and speed of the wind in your area to help decide which type to build. You could use an anemometer to determine your wind speeds.

If you are looking into windmill building, you need to know the basic parts. The base, that needs to be strong, and heavy. This will help keep the machine from tumbling over in strong winds. The tower that can be constructed from wood, or plastic tubing. The blades will harness the winds energy. The size of the blades are determined by the size of your base. If you had a five foot machine your blades would generally be one to three feet long. The nacelle is what normally houses the gearbox. A basic wind turbine uses a simple shaft to connect the blades to the tower. And the last part, the generator, that will be rotated by the windmill to produce electricity.

Here are a couple other windmill building tips. You will need wind speeds of at least 7 miles per hour to start making electricity or your own. Twelve to twenty mph is recommended for optimum results. An eight to eleven foot high machine can is capable of producing 700-1000 watts of power and can be made easily. A reminder, it is very important to know your areas laws, wind speed and directions, and power needs before beginning your windmill building journey.

A windmill is a very cost effective method to begin generating your own green power. The wind is a renewable energy source that is here to stay. There are hundreds of windmill building plans on the internet. Review the best windmill building plans here.
