Two points:
Wind turbines do not produce electricity all the time. When there is no wind, it should still be on standby;
The height of modern megawatt wind turbines is typically 65 to 90 meters and they are located in open wilderness. If you are upstairs and there is no wind, there could be two reasons: First, your building is not high enough. The most common 80 meter high wind turbine is equivalent to a 25 to 30 story building. The second floor is built in town. There are too many buildings in the city, making the wind unstable and turbulent everywhere. For example, a city is like a river bottom with many large rocks and the water flow is unstable and irregular. So when you are standing upstairs, sometimes there may be no wind and sometimes there may be gusty winds. The wind turbine is in the wind field, there is no obstruction, the wind speed is stable and lasts a long time (wind measurement and corresponding simulation calculation are required). Additionally, specific fan positions are calculated to ensure low turbulence and stable wind speed.
So the wind upstairs is different from the wind field, and the height of the building is different from the height of the wind turbine. If you can't feel the wind when you're upstairs, it's not. This does not mean that wind energy cannot be produced.
The ancestor of the wind turbine is the windmill. Early windmills were made by hand and did not have strict design specifications. They were of two types: clockwise and counterclockwise. In the suburbs of London, England, you can see two types of rotating wind turbines. There is little difference between them except the direction of rotation.
Surprisingly,the world famous Dutch windmills are a typical representative of windmills, most of which rotate counterclockwise. The first Dutch windmill imported from Germany gradually developed its own characteristics during the localization process. Due to its long history, the windmill's reverse temporal rotation is no longer available. One thing to say is that the Dutch don't like ink and are lazy in the blade installation process. When installing a wind turbine, it is necessary to nail a mesh fan to the main mast, where a few wind turns will be placed on the surface. Since most Dutch people are also required to use their right hand, they move the pole away from the left, which ultimately results in a counterclockwise rotation. As Dutch windmills became popularaires, this spinning method continued to be imitated and spread throughout later generations, and it continues today.
From a physical point of view, there is no difference in the power generation performance of a wind turbine between clockwise and counterclockwise. 'a watch. We could even see two rotating wind turbines, but that would be visually uncomfortable. In fact, most people never realize that we are more accustomed to looking at objects in a clockwise direction.
Why do wind turbines move clockwise? Few people intentionally care about the direction of rotation, but most of the rotating objects exposed to long-term daily life have adopted clockwise rotation, which has gradually become a habit. Modern rotating machines use clocks in thehe clockwise direction, the oldest timekeeping tools are Japanese. The shadow of the Japanese dial rotates clockwise in the northern hemisphere, and in the southern hemisphere the shadow rotates counterclockwise.
In other words, if the person who invented it was Brazilian, all clocks would now run counterclockwise, and more machines would run counterclockwise. Clockwise. With the advent of the clock, there is no longer a southern hemisphere in the sense that the southern hemisphere is accepted. For a long time, Earthlings roamed the southern hemisphere and silently recognized as a unified rule of clockwise rotation.
