Do You Know? China Design the World's Largest Wind Turbine

China is making a prototype wind turbine for the largest wind power.

President Sinovel Wind Group Co. Ltd. firms that developed the prototype said that wind turbines can be placed either on land, offshore to tidal areas.

The kind that is being created Sinovel is the first made in the country. Previously, Germany was the only country able to independently develop a turbine-largest in terms of capacity and is the only country to have tested a prototype.

The turbine will have propeller blades along the 128-meters in diameter that will catch the wind with a large capacity and is expected to be more efficient in utilizing wind resources.

Tao said the original production of large turbine will accelerate the development of offshore wind power in this country.

China racing to exploit offshore wind with their first wind turbine operates with a total capacity of 100 MW which is operated in Shanghai in August 2010, by utilizing the 34 mill.

In the same year, China also has completed the public tender for wind power capacity of 1GW offshore in eastern Jiangsu Province plans to start construction this year.

Sinovel addition, other companies in China are also developing a turbine with a large capacity that is Xiangtan Electrical Machinery Co. Ltd (XEMC), based in Hunan Province. In October last year they produced a prototype turbine power of 5mW.

Before 2000 China needs to rely only wind turbines and equipment imported from Europe.

Chinese wind turbine maker has expanded its output through a production license or design along with foreign partners. China has been making wind turbines more than 80. Three wind turbine maker in China, Sinovel, Goldwind and Dongfang Electric, now a part of the 10 best-in-turbine maker world.

Until late 2010, electricity generated by the turbines that generate electricity installed at 44.7GW. Is the largest in the world by donating donate 23 percent of total world electricity.

Do You Now? Gravity


Gravity is the force of fundamental interactions in nature. The space program planners continually investigate this style. Because, in the solar system and space flight, gravity is a force that plays an important role. Studies that explore the dynamics to the objects in space is called celestial mechanics. Now, knowledge of celestial mechanics allows to determine how to place a satellite in orbit around earth or to choose the correct path for sending a spacecraft to another planet.

Since the days of Ancient Greece, people have tried to explain about the solar system kinematics. Therefore, before discussing Newton's law of gravity, it helps if you also understand the thought before Newton discovered the law of gravity.

Plato (427-347 BC) Greek scientists suggested that the stars and the moon moves around the earth to form a perfect circle trajectory. Claudius Ptolemaus in the 2nd century AD also gave a similar opinion called the geocentric theory. This theory states the earth as the center of the solar system, while the other planets, the moon and the sun revolved around the earth. However, opinions of these two figures can not explain the complex movements of the planets.

Nicolaus Copernicus, a scientist from Poland, trying to find the answer is simpler than the opinions of Plato and Ptolemaus weakness. He argued that the sun as the center of planets and planetary systems of other planets including the earth round the sun. Copernicus assumption provides a solid foundation to develop views on the solar system. However, the disagreement of opinion among scientists is still there. This encouraged the scientists to gain a more thorough observation data and concrete.

Tyco Brahe (1546-1601) managed to compile data on planetary motion carefully. Data collated Tyco then studied by Johannes Keppler (1571-1630). Keppler discovered regularities of planetary motion. He said the three rules of planetary motion, now known as the law I, II, and III Kepler. Kepler's laws states:
  1. All planets move in elliptical path centered on one central point (the sun).
  2. Line connecting a planet to the sun will provide the same broad strokes in the same time.
  3. Square of the period of each planet around the sun is proportional to the cube of the average distance of the planet to the sun.
Copernicus and Keppler legal opinions have the same style as the cause of the regularity that the motion of planets in the solar system. In 1687, Isaac Newton proves in his book "Principia" that the motion of the moon around the earth caused by the influence of a force. Without this force the moon will move straight with constant velocity. (In accordance with inertia), this force called gravity.

The force of gravity affect the movement of planets and other celestial bodies. In addition, the force of gravity is also the reason why all objects fall towards the earth's surface. Thought is the work of Newton's remarkable because it can unify the theory of mechanics and mechanics of objects on earth object in the sky. This can be seen from the explanation of free fall and planetary motion in the solar system.

Do You Know? Venus is Insectivorous Plants


In addition to predators that often we have seen, it turns out there are some plants that are also "hunt" with the ability to capture prey that is amazing. One is a plant-insect predator named Venus. This plant has a system of trap to trap, catching and eating insects that perch this it. Plant attract insects with a charming red leaves. Despite this admirable trait in him, he himself did not realize this. Insects are tempted by the delicious aroma of the resulting glands around the foliage of plants Venus. It then flew over and then landed on top of plants without the slightest suspicion of the danger that lurk. When moving into the source of "food", he touched the hairs that appear as harmless on the surface of these plants.

When approached him feel the touch of insects, plants are moving quickly folded and tightly closed leaves. This movement makes the insects trapped and pressed between the leaves. This leaves more and more closely flanking a result of insect wings that touch your hair repeatedly. These plants then remove fluid "crushing and solvent meat" in insects. In a short time, he crush their prey to become like mush and then eat this delicious dish.

Venus has the ability to close the plant leaves with a very high speed. Faster than the fastest motion to close the fingers of human hands. The proof, humans often can not catch a fly that landed on the palm of his hand, but the plant Venus did with ease. What is interesting to note is how the plants that do not have the muscles or skeleton is able to perform a very rapid movement?

There is a very complex electrical system at the plant of Venus. Stimulation caused by touching the body hairs of insects on Venus forwarded to the receptor (receiver system stimulation) under the plant hairs. Then continue this receptor stimulation in the form of electrical signals to the motor cells that cause the leaves Venus make quick and sudden movements. Finally, the mechanism is switched on continuously to keep the insects so as not to loose.

What happens at the cellular level motor? Immediately after this motor cells receive electrical stimulation, they change the concentration of water in their bodies. The cells on the inside of trap release water from his body and then shrink. This phenomenon is similar to a deflated balloon and remove the air. In contrast, cells on the outside of trap to absorb excess water and expand. This process happens quickly so that the plants are closing their leaves with a very high speed.

In addition, the digestive gland of trap were also activated. As a result of stimulation, these glands begin to release liquid to crush and dissolve the insect's body slowly. Although very powerful way to dissolve the protein, these chemicals do not harm the plant leaves Venus itself. In this way, the plant Venus prey eating porridge that has been turned into a bowl of rich soup of proteins.

After eating a meal, before moving mechanism of trap Venus so close, now works on the contrary to open it. To activate the trap, Venus hairs must be touched twice in succession. With this double action mechanism, the plant Venus was never close to useless without a clear purpose. For example, the trap will not become active and closed when a raindrop falls about it.

Here, which is very important to note is that Venus, the hunter who these experts, has no brain or organs semisalnya, so that he could not think. Indeed, Venus did not realize extraordinary ability, which makes it able to hunt for insects that can fly quickly. All this shows a system trap, capture and destruction of the insect with a very accurate precision, technique and design a perfect in their parts even the smallest.

Do You Know? Hot Dog

Fried sausage squeezed bread, something like that is what his name hot dogs. This western-style food turned out to have invaded almost all corners of the world, including Indonesia. Food import was already familiar to the tongue of our society.

Hot Dog (frankfurter, frank, wiener, weenie) is a type of sausage that is cooked or smoked and has a smoother texture and flavor are more delicate and moist than in most sausages. Hot dogs are often eaten by hand (finger food), especially in the United States, and usually eaten with soft bread (bun) together with the sausage-shaped, sometimes accompanied by condiments and toppings. Sandwich formed from this combination also called hot dogs.

"Beware of easy Choking"

Fast food, hot dogs declared by doctors as a dangerous food for children. Because the elongated oval shape raises the risk of choking. Pediatric Academic famous American in the United States (U.S.) has called for changing the shape of hot dogs for the sake of minimizing the danger. Each year the events that resulted from choking the food has killed 77 children in the U.S. and more than 15 thousand treated in emergency rooms. Approximately 17 percent of cases result from eating hot dogs, according to a report issued by the academy.
"Companies have to redesign the food foods, including meat products. They should change the shape, size texture, and other characteristics that can cause children to choke, "the academy recommendations, as quoted by the Telegraph.

Director of the Center for Injury Research and Policy Child Health at Children's Hospital of Columbus, Ohio, Gary A Smith MD, DrPH in USA Today stated, hot dogs throat can close the channels of children. "I am an emergency physician for the child, and to remove blockages from the throat hot dog is a very difficult thing," he explained.

It also assesses the Academy there are some foods that can cause children to choke, such as raw carrots, grapes and apples. It is recommended, the food should be cut into small pieces before consumed by children. Marshmallow and peanut butter can also cause blockage of the child's throat. U.S. Federal law requires that the label "choking hazard" on certain toys, such as small balls, balloons and other small toys.

Do You Know? History of Imlek


The origins of Chinese New Year celebrations too old and older to be studied. However, the general said, the Chinese word, "Nian" or the means 'in' in the Malay language, is named for the giant who often prey on the eve of the new year begins.

Children, close relatives and those who have not been given a red packet for wedding a bright future.

Chinese Lunar Calendar
Chinese lunar calendar is the world's oldest calendar, used since 2600 BC. Use of this calendar was introduced by Emperor Huang Ti. Like the Western calendar, the Chinese lunar calendar is based on annual turnover which initiated the beginning of the turn of the month. Therefore, beginning in the Chinese calendar falls around January and February.

One complete revolution around the earth takes 60 years and consists of 5 rounds each of which lasts 12 years. Chinese lunar calendar each year based naming 12 animals.

The Chinese community believes that every human is born with the influence of personality and attitude on the animal called man is born in the year.

Chinese New Year decorations
Before the Chinese New Year celebration, Chinese families would decorate the house with vases containing flowers are blooming grow, bag-bag containing lime, and also a bag containing eight kinds of dried fruit is sweet. On the walls and doors will be hung with beautiful decorations, such as poetry and greeting the new year painted on red paper.

Orange 
Normally, the Chinese people, they will bring a bag filled with orange and red packet will be provided when visiting friends and family during the two week celebration of Chinese New Year.

  • Kumquat (an orange) - wealth
  • Coconut candy - intimacy
  • Peanut - sustainable living
  • Longan - symbolizing a person will get a lot of good boys
  • Fruit of the lotus - a lot of kids

Do You Know? Thomas Alva Edison


Thomas Alva Edison was the inventor of America and is one of the greatest inventors in history. Edison began working at a very young age and continued working until his death. During his career, Thomas Alva Edison had been around from 1093 to patent his invention, including an electric light bulb and the gramophone, as well as film cameras. All three findings raise major industries for the electric industry, recording and film that ultimately affect the lives of people around the world. He is also known as the inventor of applying the principle of 'mass production' for his discoveries.

Edison's own gain expertise in the field of electricity and telegraphy (the telegraph for communication) during the teenage years. In 1868, at age 21, she has developed and patent his invention in the form of a machine that records the telegraph.

The days of childhood, Edison just attended a formal school for three months, then all his education from his mother who taught Edison at home. Edison's mother taught Edison how to read, write, and mathematics. He also often gave and read the books for Edison, among others, the books come from authors such as Edward Gibbon, William Shakespeare and Charles Dickens.

Edison at age 12, earn revenue by way of a job selling newspapers and newsletters, apples, and candy on a railway line. At that age also, Edison has lost almost all hearing because of her illness, the disease makes it a half-deaf. Edison once wrote in diarinya: "I have never heard a bird sing since I was 12 years old."
At the age of 15, Edison, while still selling, bought a small printing press used hereinafter to be installed in a car trunk. Then he prints his own newspaper, Weekly HERALD, which is in print, edited and sold in places he's selling.

In the summer of 1862, Edison saved a three-year-old boy who almost hit by a car. The father of the children removed is the head of the train station in place to sell. And as gratitude, the head of the station taught Edison how to use the telegraph. After 5 months of studying the telegraph, Edison worked as an expert telegraph for 4 years. Almost all the salary he gets is spent with a variety of laboratory building and electrical equipment.
Edison is very pleased to learn something and read the books there. Of those studied, Edison apply these lessons in a way his little experiment in the laboratory. Edison lived in his lab, only sleep 4 hours a day, and eat the food brought by his assistant into his laboratory. Edison experiment to experiment and continuously until his discoveries to be perfect. Perhaps the words that adequately describe the abilities which are Edison: "Genius is 99% hard work"
