• The blades – A windmill can consist of any number of blades from four to 20. Some special wind mills have higher number of blades.

• The tower – The tower holds the rotating blades high up in the air so that the winds rotate them.

• The shaft – The shaft is responsible for joining the blades with the tower and for the smooth rotation of blades.

• The generator – The generator is what generates electricity from the mechanical energy. It also stores power for future use.

• The base: The base of the windmill keeps it grounded to the earth.

What factors affect windmill design?

There are many factors that affect the design of a windmill. Let’s understand the major ones:

• Wind speed: The wind speed can be accurately measured with the help of an anemometer. It is not possible to determine the right kind of wind mill without knowing the accurate wind speed.

• Wind direction: For designing a windmill, it is also important to know the direction from which the wind flows most of the time.

• Change in wind speed: Apart from the constant speed of mind, it is required that you know how the wind changes its speed.

• Change of wind direction: The direction of wind will not be constant, so it important to note the way it changes its direction.

• Obstructions on the site: It is best t install a windmill at a place without many obstructions. Look out for existing and potential structures that may affect the performance of your windmill.

• Wind turbulence: The movement of wind is not always predictable. However, it is a good idea to understand the patter of wind turbulence in your site.

• Distance of wind activity from the ground: The height of the tower is dependent on the height at which the wind is active.

What are the possible designs of windmills?

Aerodynamics determines the design of a windmill based on the factors mentioned in the section above. The designs of windmills vary in the following measures:
• Number of blades
• Shape of the blades
• Height of the tower
• Kind of generators
• Distance of the installation spot from the ground
• Distance between the tower and the generator

These solutions can help you combat power outages, reduce your electricity bills, and also help the environment.

This article will explore the cost-effective wind power solution that you can employ at home.

Wind power solutions work best when the following conditions are met:

• You have a house or farmhouse spread over a big area. Typically, wind power solutions are employed in areas that spread over an acre.

• The average wind speed in your area is around 11 miles per hour. If you stay in a place that has little wind flow, your system will not work. Consult an expert before installing the wind power solution at home.

• You need to draw water from external sources. You can install a wind power system even when you do not need to draw water from outside. However, if you need to draw water from outside on a regular basis, a wind power system offers the best solution.

• Your house needs a lot of uninterrupted power supply. Combating those power outages is easy with the pollution-free wind power systems. You need no longer worry about a break in your work because of a power uncertainty.

A typical wind power system comprises of a tower and five blades to churn out wind energy. The length of the wind tower varies depending on the location of your house. You may need a longer tower if you are in low-wind zone; you can work with a shorter tower if you live by the beach. Using a wind generator, this wind energy can be converted into useful electrical energy to be employed at home for running various electrical appliances. You can even store the power generated for later use, making wind generators more efficient than convention power systems.

If you are confused with the wind power jargon, here’s a piece of information for you. The terms, wind mills, wind turbines, and wind generators are used to refer to the same machine.
