The Benefits Of Windmills

1003 Words5 Pages

What is wind?
Wind is a form of energy, caused by differences in air pressure. Air under high pressure moves toward areas of low pressure. The greater the difference in pressure, the faster the air flows. Why does wind or air pressure matter, you may ask? It is capable of many great feats, some destructive, such as destroying buildings, cascading walls or even lifting trees from their roots in the ground.
The speed of wind is measured on the Beaufort Scale, which goes from the speed of less than 1.1 km/h, a rather slight speed, barely a breeze itself. To an outragous speed, more than 117.4 km/h, causing hurricanes, major damage to households, death, debris hurled about, etc.
Are there any advantages of wind then?
There are many advantages we can exploit from wind speeds. Wind energy has been used to our advantage since ancient times. We have been using the wind for sailing ships for the past 5500 years. The first practical windmills were used in Sistan, early in the Middle Ages. Eventually they became used by many Asian and Middle Eastern civilisations, for example "by 1000 AD, windmills were used to pump seawater for salt-making in China and Sicily". We still use the wind to sail today

In the 19th century, along with the beginning of the Industrial Revolution, we started to see even more practical purposes for windmills. We had started to provide electricity with windmills. In 1887, Professor James Blyth (a Scottishman) had begun to install his very own windmill,

    As the storm passed west of Cuba, its effects extended as far east as Havana, where winds reached 56 mph (90 km/h). Across the Florida Straits, Key West, Florida, recorded 36 mph (58 km/h) winds.[4] The strongest sustained winds measured in association with the storm were 107 mph (172 km/h) in Mobile, Alabama, corresponding to a one-minute average of 87 mph (140 km/h) adjusted for modern recording techniques. Although not directly recorded, sustained winds of Category 3 intensity probably affected coastal Mississippi and Alabama, with Category 2 winds affecting Florida.[5] Throughout the affected region, telephone and telegraph infrastructure was blown down, crippling communications.[12]

  • Hurricane Iniki Research Paper

    1939 Words  | 8 Pages

    Here at the University of Florida, the field of wind engineering is a subject to which a lot of research and manpower is dedicated, particularly concerning hurricanes and the large wind loads associated with them. These powerful storms are generally associated with the eastern and gulf coasts of North America, but they can and do form elsewhere. Hawaii, surrounded by the cold waters of the Pacific Ocean, is not typically associated with hurricane activity, but in September of 1992 the island state was struck by Hurricane Iniki. Within a lifespan of a little more than a week, Iniki was able to completely change the relationship Hawaii had with Hurricanes by battering the islands with strong winds and exposing the complacency fostered by years of mild hurricane seasons. In the years to come, this storm was to serve as the basis for Hawaii’s push to better prepare for potential storms and avoid another disaster of this magnitude.

    One of the reason that cause hurricane it’s depend on environment. Hurricane use the warm air and warm ocean as the power of the storm. As being said, the warm temperature that form above the ocean create the rotating wind because when warm air and cool air are touching together then it makes an area of lower pressure, warm air is lighter than cool air so higher air pressure pushes into the lower pressure area and it cause hurricane.
