The word "progress" in modern man causes various associations. This is a movement forward, the rapid growth of various advanced technologies.
But ask any person what specific advanced technologies he knows. In addition to a cell phone and an iPhone, he will not be able to name anything.
Car brands are changing, as are their appearance with internal filling. But just as they drove internal combustion engines more than 100 years ago, they still drive today.
Planes fly just like they did in the distant past.
In practice, there is not a single breakthrough technology. Only one copyright of past achievements.
Rummaging through memory, opponents happily recall Elon Musk.
This is who Leonardo da Vinci is today. For what he does not undertake - everything is on his shoulder. These are his most daring developments and inventions.
One of them is Hyperloop One.
Musk, in opposition to building a high-speed rail line between California and Los Angeles, proposed building a vacuum train that is not only cheaper, but much faster than any high-speed train.
It was announced that it was possible to achieve a speed of 1220 km / h. And already on tests in December 2017, a speed of 387 km / h was achieved.
The principle of operation of a vacuum train is simple.
A pre-vacuum is created inside the pipe, that is, the air is pumped out almost to zero. The capsules with passengers are driven by a linear motor that creates an electromagnetic field.
The stator is an aluminum rail located on the track floor, while the rotor is located in a capsule.
To reduce the resistance to movement, a system has been created that allows the capsule to "float" over the rail.
That's all. Seems like some pluses. True, if the tightness of the pipe is broken, and this is possible during an earthquake, or a drunk truck driver drives into a support of the highway, then a shock wave is immediately created, from which all passengers will instantly die.
But what sacrifices will you not make for the sake of progress.
And it would seem that here it is a breakthrough technology. From New York to Beijing can be reached in 2 hours. I drank coffee a couple of times and that's it, it's time to go out.
But harmful alternatives do not calm down. They say that all this has already been invented before us. Let's check it out.
