Advice On Windmill Building
Would you like to construct a windmill?
Windmills have been with us for centuries. The concept of a windmill is to capture the winds energy to rotate the blades, changing wind energy into mechanical force. This mechanical force can be used to operate a generator and produce electrical power. Originally they were used to pump water or grain. Modern versions typically use high tech, lightweight components such as carbon fiber in their design. You don’t have to use these expensive materials. Windmill building can be done by a skilled, do it yourself type of person, for a very affordable cost. With simple hand tools, access to a hardware store, and some construction ability, you can make your own windmill.
The main goal of a windmill is to maximize the conversion of wind energy into mechanical energy. It needs to be tall enough to get above trees and other obstacles. First check out your local building regulations 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 catch the wind. They should be lightweight wood or plastic and rotate with ease Just like an airplane propeller.
The two types of windmill designs are horizontal axis and vertical axis. The horizontal axis ones are the most often used. Their vertically spinning blades face the wind. The downfall to this kind of windmill is that when the wind changes direction, the horizontal axis type won’t be very efficient. The vertical axis type can produce wind energy from any direction. It’s main shaft is vertical and the 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 of your area to help determine which kind to build. You can use an anemometer to measure 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 will be determined by the size of your base. On a five foot machine your blades would generally be one to three feet long. The nacelle normally houses the gearbox. A basic wind turbine uses a shaft to connect the blades to the tower. And the last part, the generator, that will be turned 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 generating electricity or your own. Twelve to twenty mph is recommended for best results. An eight to eleven foot tall machine can is capable of producing 700-1000 watts of power and can be built easily. A reminder, it is very important to know your areas laws, wind speeds and direction, and power needs before beginning your windmill building adventure.
A windmill is a surprisingly cost effective method to start producing your own renewable 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.
