There are two diagrams about the design of a wind turbine and it best position to put. The materials include blades which can be fiber glass or wood, wind sensor, generator, steel tower and computer to get the information from sensor adjust blades include direction and angle.
The first picture shows the process of wind turbine produce energy. The steel tower is located around the shoreline. In the top of the tower, it is existed blades. When the wind was flowed, it will be spin. It will produce energy to the generator. As the result, the electricity is gained 1.5 megawatts. Wind sensor then detects the speed and direction of wind and its information will send to the computer.
The wind turbine can be optimum in working when it is placed in the right position. According to the second diagram, the wind turbine will be worked optimum when it is placed in the high position around the sea. It can give twice output then the turbine which existed in the domestic turbine. The maximum wind is the most strength in the high level than in the sea or in the domestic turbine.
It is becoming increasingly common for people to go online to buy what they need rather than going to a shop or travel agent to do so. Although there are some dangers and disadvantages to internet shopping, I believe that the convenience often outweighs any drawbacks.
There are two main dangers and disadvantages to buying things on the internet. The one that attracts the most publicity is the problem of internet fraud. Unless the website is secure, hackers may be able to copy your credit card details and steal your money. A further disadvantage is that you cannot examine what you are buying until after you have bought it. This means you may sometimes buy something that you do not really want.
On the other hand, shopping for certain things on the internet has several points in its favor. The main one is its convenience. People who want to compare products and prices can look at all this information on a website without having to go from shop to shop. Also, they can make their purchases at any time of day or night and from any part of the world. The other advantage is that because internet companies do not need a shop, the products which they sell are often cheaper.
All in all, I think that the advantages of using the Internet for buying things such as books, computers and air tickets are greater than the disadvantages. However, someone that wants to buy clothes should visit shops because they need to see and touch them before buying them, and I would recommend purchasing them online.
The past decades have seen a considerable increase in the availability of online shopping. Yet, there remains some disagreement as to whether the overall effect of
this shopping trend has been positive or negative. While there are certainly valid arguments to the contrary, I personally believe that the benefits of the internet
shopping far outweigh its drawbacks. The two associated reasons are as follows.
To begin with, e-shopping has a positive role to play in the world due to its convenience and cheapness. It is evident that you can buy a plenty of goods on a
website. We not only save our time, but also buy goods in a relatively lower price. One particularly good example to illustrate is TaoBao. The website provides a
comparison prices of the same good among various shops so the buyers can buy a good in the lowest price. Moreover, the physical distribution service sends all the
things to our home. Therefore, online shopping has brought significant changes to our life.
Apart from its convenience and price, one point which I believe to be absolutely pivotal is that we are allowed to shopping in any conditions. In other words, there
are no limitations for us to shopping. No matter what weather or time it is, we still can purchase products from the internet. It is essential for a lot of cities dwellers
since some shopping malls closed when they after work. Despite some critics may claim that online shopping is unreliable that the goods may be different from the
internet pictures because some merchants use online shopping to deceive the consumers, most of us have benefited greatly from online shopping. Provided that
we choose a good reputation or world renowned shops, we are merely to be deceived by sellers.
By ways of conclusion, I once again reaffirm my position that online shopping has had a positive impact on modern life because of its convenience and cheapness.
