From Beijing to Shanghai, more than 1200 kilometers, it takes more than 5 hours by high-speed rail and 2 hours by plane. However, there is a kind of transportation that is expected to connect the two cities in one hour-the super high-speed rail.

Elon Musk, the founder of the popular electric car brand Tesla, has never lacked imagination and execution. From Space X's space exploration to the family battery changing the world, this "realistic version of Iron Man" Pushing the boundaries of the world's technological imagination time and time again, the Hyperloop super high-speed rail is an excellent example of its gradual transition from imagination to reality.

Since Musk proposed the Hyperloop super high-speed rail, this concept has attracted worldwide attention and has developed rapidly in recent years. At present, many companies are involved in research and development, and all have begun to build the test track, and the full-size test track will be completed as soon as around 2016.

Hyperloop is the "fifth mode of transportation" proposed by Musk in 2013. It is expected to become a faster, cheaper, and more energy-efficient mode of transportation than airplanes, trains, cars and ships.

It is envisaged that the speed of the super high-speed rail can kill planes in seconds, is immune to various complex weather, can travel on the ground, underground or even the seabed, and it can also use solar energy to replenish its energy.

Once the technology is feasible, the cost will be very low. It can be said that the advantages of all current transportation methods are combined. If realized, it can be said to be a major milestone in the history of human transportation. So the question is, how is it achieved?

The technical principle of the Hyperloop

The technical principle of the super high-speed rail is not difficult to explain. The core is to place the train cabin in a pipeline that is almost vacuum and use magnets to provide power for acceleration. Because the pipeline is close to vacuum, the air resistance-the biggest obstacle to the acceleration of high-speed trains-will no longer exist, and the super high-speed train with the help of air compressors to provide lift and magnets to provide thrust can theoretically approach the speed of sound (1200+km/h ).

The speed of the super high-speed rail far exceeds that of the fastest maglev train, which has a speed limit of only about 500km/h. Because the magnet power of the maglev train needs to provide lift, in addition to providing thrust, the magnet power of the super high-speed train is all used for propulsion, and with close to zero air resistance, the speed of the super high-speed train is more than twice that of the maglev.

Contending competition

After the imaginative project of the Hyperloop was proposed, it was not led by Musk and his subsidiary Space X. Instead, many companies are participating in the research, showing a competitive relationship with each other. The specific research directions and progress of each company are not exactly the same, and they are generally at the stage of laying test tracks.

Space X

Since the concept of Hyperloop was proposed in 2013, Musk has not been idle. Space X recently announced that it has begun construction of a Hyperloop test track. This nearly 2 kilometers long test track is located outside of Hawthorne, California-near Space X's headquarters to test various cutting-edge technologies of Hyperloop. .

In addition, Space X also held a Hyperloop design competition, open to everyone, encouraging college students and independent engineering teams to participate. Since this is still a new engineering field, launching a competition will help to promote the resolution of various technical problems of the Hyperloop.

►Hyperloop Transportation Technologies

In response to Musk's call, many companies have begun research and development projects for the Hyperloop. One of the most prominent is Hyperloop Transportation Technologies (HTT). The track they are building can be tested as soon as next year.

This track is 8 kilometers long and is located in the Quay Valley region of California. Once the track is successfully built, it will become %E
