Tesla Immigrants to Mars Video

Recently, Tesla's rights protection incident has been raging, once again sending Tesla President Musk to the forefront. From Tesla to space exploration technology company, from new energy electric vehicles to super high-speed rail, one subversive idea after another made him climb to the top of the 2 1 century technology altar, and even Iron Man in The Avengers was based on him. However, in addition to new energy electric vehicles, all Musk's ideas about the future are still in the experimental layout stage, and even many of them just hear their voices but don't see their deeds. Super high-speed rail is one of them. So, what kind of black technology is the super high-speed rail with a speed of 1 126 km? Why hasn't it been put into practice so far?

First of all, let's take a look at what kind of person Musk is. In fact, Musk's international reputation is mixed. Those who agree with him regard his words as the standard, while those who deny him regard him as a madman in daydreaming. I believe many people have seen The Avengers. One of the Iron Man used his scientific inventions to become a hero who saved the aliens from attacking the earth. Musk positioned himself to use technology to solve the crisis that mankind may face in the future and promote the future development of mankind. For example, there may be energy shortage and environmental protection problems in the future, so there are new energy electric vehicles; In the future, the earth may no longer be livable, so there is a plan to immigrate to Mars; In order to save travel time, the concept of super high-speed rail appeared. Musk is like a child of 12 years old, dreaming of the future and seeking to realize the dream scene.

What is unique about super high-speed rail to attract this dream future Musk? There are two main reasons. The first is ultra-high speed. The theoretical maximum speed of super high-speed rail can reach 5000 kilometers per hour. It takes only 26 minutes to get from L.A. to new york, two hours to get from new york to Peking, and three hours to circle the earth. The second reason is low cost. Because the cost of vacuum pipeline is cheap, only 1/4 for kilometers and 1/2 for high-speed rail, the cost reduction will further lower the ticket price, and Musk is a madman who pursues low cost.

So, what is the super high-speed rail envisaged by Musk? 20 13 musk put forward the idea of super high-speed rail, which is a transportation mode with "vacuum steel pipe transportation" as its theoretical core. Its shape resembles a capsule, also known as capsule high-speed rail. Magnetic levitation and low vacuum are adopted. In the super high-speed rail envisaged by Musk, the train is like a space capsule, with a single unit 183 kg and a length of about 4.87 meters, which can only accommodate four or five passengers. Friends can imagine for themselves that in a closed vacuum tube, the high-speed rail will be launched like a bullet at an unimaginable speed. This year, Musk tweeted that the designed super high-speed rail can reach 1 126 kilometers per hour.

Then, why does Musk claim that the super high-speed rail in the future landing experiment can reach the speed of 1 126 km/h? There are two main reasons. The first reason is that the space it runs in is vacuum. Presumably, friends have experienced different speeds to control the oncoming wind. When the speed is low, the oncoming wind is mild. When the speed is relatively high, the oncoming wind will be sharp, which will make people feel breathless to a certain extent, that is, the air resistance that people feel when sitting in the car. So generally speaking, the faster the speed of the manipulator, the greater the air resistance. Based on this, the super high-speed rail adopts vacuum mode, specifically, it is to build a closed pipeline, and then create an environment as close to vacuum as possible in the pipeline, thus reducing air resistance and improving speed. The second reason is the use of magnetic levitation. Through magnetic levitation technology, the train can be in zero contact with the track, thus eliminating the friction between the track gauge and the wheels and greatly improving the speed. At present, trains equipped with maglev technology have been put into use in the world, and maglev trains have also been built in China and Shanghai, with a speed of 430 kilometers per hour, while the top speed of ordinary high-speed rail is 350 kilometers per hour.

Since there is a mature theory, why can't the super high-speed rail take root? There are four main reasons. The first is the limitation of the existing technology. As mentioned above, one of the core reasons for speeding up is vacuum operation, and it is a vacuum environment calculated in kilometers. However, the existing vacuum technology cannot vacuum such a long pipeline. In addition, the current magnetic levitation technology needs to be improved, far from making the high-speed rail faster than the plane. The second reason is the high cost. Although the construction cost of vacuum pipeline is expected to be very low, it is actually the opposite. According to a document of Virgin Hyperloop 20 16, the construction cost per mile is between $84 million and $ 1.2 1 billion, and the super high-speed rail needs to build a long running pipeline to run in a vacuum pipeline, which is very expensive. The third point is that there is no practical plan. The speed of the super high-speed train is 1 126 kilometers per hour, which means the distance between stations needs to be long enough, otherwise the train needs to start braking as soon as it leaves. However, if the venue is set far away, there will be fewer people radiating, and the practicality will be greatly reduced. The fourth point is security. Physicist James Powell once said that minor mistakes in the super high-speed rail track may lead to serious disasters, such as pipe wall perforation and pipe displacement, and Wang, an academician of China Academy of Engineering, also pointed out that vacuumizing the track will cause considerable safety hazards to passengers. In fact, the last three points are all based on practical considerations after the technology is mature, but the main reason that restricts the super high-speed rail from taking root is technical restrictions.

Therefore, it can be seen that the super high-speed rail is not feasible technically, safely, economically and practically at this stage. Is the super high-speed rail proposed by Musk a scam? Not exactly. Although Musk constantly uses the gimmick of super high-speed rail to "draw cakes", it is really necessary to study the principle behind it-vacuum plus magnetic levitation. However, China doesn't do much research on super high-speed rail, and even takes the lead in landing experiments. China Aerospace Science and Industry Corporation announced the super high-speed rail research project in 20 17, and gradually realized the highest running speed of 1000-4000 km by using vacuum tube and magnetic levitation technology. What's more worth mentioning is that this year 1 month, the world's first high-temperature superconducting high-speed maglev engineering experimental line will be opened in Southwest Jiaotong University. At present, the speed has reached 600km/h, which is only high-speed maglev technology. In the future, vacuum tubes are expected to increase the speed to more than 1000 km per hour. Fu Zhihuan, an academician of China Academy of Engineering, also thinks that even though the high-speed rail is controversial and far from landing, it is still necessary to study it, because it will have a place in the future traffic.

In today's world, with the rapid development of science and technology, the innovation of transportation tools is getting faster and faster, but they can be successful not by imagination, but through long-term research and development and testing. It is undeniable that many of Musk's ideas are bold and fit for future development. But the word future itself is far away and needs to be approached step by step. The same is true of super high-speed rail, which is high-tech rather than a scam, but it takes countless people decades to study it step by step.
