| A windmill is a simple device that harnesses the | | | | varies depending on its output capacity. When |
| winds power. Early civilizations used windmills for | | | | purchasing a windmill kit, it is important to check |
| various purposes like grinding rocks, corn and | | | | the output first and see if it can generate enough |
| even towing boats. The windmills used centuries | | | | electricity for your household.o Base - The base is |

| similar. They still share the same basic parts and | | | | strong base is necessary so the windmill could |
| use the same principle. | | | | withstand strong gust of winds. It also eliminates |
| A typical windmill consists of several major parts. | | | | vibrations that could damage the device. |
| These parts are found on almost every windmill | | | | Due to various wind conditions, it is also necessary |

| because of this part. A windmill consists of four to | | | | windmill's design to make sure it works efficiently |
| twenty individual blades depending on the design. | | | | even with low wind speeds. The design of a |
| Small scale windmill applications uses blades made | | | | windmill varies on parts like; the number and the |

| - A tower is a tall structure made up of plastic or | | | | anemometer, we can measure the speed of the |
| steel. A tower holds the blades up in the air. The | | | | wind. Windmill design varies depending on wind |
| height of a tower varies depending on the location | | | | speeds. Some designs are for low wind speeds, |
| and wind speeds. Taller towers are required on | | | | while others are for durability especially on areas |
| areas that have lower wind speeds.o Shaft - The | | | | which has strong wind speeds.o The winds |
