Hyperloop One Video Shows It Works!

Hyperloop One's prototype has completed a first full systems test in a vacuum, reaching a speed of 70 mph. The test sled was able to magnetically levitate on the track for 5.3 seconds and reached nearly 2Gs of acceleration.

The startup said the privately conducted full systems test happened on May 12, 2017, and a spokesperson for the company told Ars that test results are being reported now because Hyperloop One is ending Phase 1 of testing and entering Phase 2, where the prototype vehicle will be pushed to 250 mph.

In a press release, the company wrote: “Hyperloop One tested all the system's components, including its highly efficient motor, vehicle suspension, magnetic levitation, electromagnetic braking, vacuum pumping system and more, proving the full system's components operate successfully as a single integrated unit in a vacuum. Nearly 200 engineers, fabricators, welders, etc. dedicated thousands of hours to make this test successful.”

The idea of trains traveling quickly in evacuated tubes is actually a pretty old idea; the concept was originally proposed for freight delivery by George Medhurst, a London businessman in the early nineteenth century. His second proposal in 1812 was for a system that delivered people

However, science fiction writers loved the idea. In his 1929 classic Through the Air Tunnel, Harl Vincent described the 22nd century version of Elon Musk's Hyperloop idea - he called it the air tunnel:

"You know how the regular air tunnels operate?”

“Not fully. It has always been quite a mystery to me, but I do know that radio has something to do with it.”

“Yes it is radio, of a sort. You see the so-called air tunnels are hollow cylinders of etheric vibrations projected from point to point in the same manner as the regular beams over which industrial power is trans- mitted. In the case of the great transcontinental tunnel there are twin tubes of these vibrations stretching in a huge arc from coast to coast, one for eastbound and the other for westbound traffic. The cars travel within these cylinders. The vibrations themselves are very complex in nature. One component provides insulation against the elements as effectively as though the cars traversed a solid metal tube. Another provides the dark color by day and the brilliance by night that warns standard aircraft of the location of the tubes. Still another energizes the coils in the cars, which coils provide the powerful repulsive force that neutralizes gravity and allows the cars to remain suspended either when stationary or when in motion. But the method of propulsion is what makes travel at extremely high speed impossible.”

"But Jimmy, the trip is made in about six hours. Surely that is fast enough for anyone.”

“No, dear, it is not fast enough under present traffic demands. Of course the cars travel much faster than the standard aircraft but with my scheme they can be made to operate at five or possibly six times their present velocity. You see, as it is now, the tubes are filled with air at atmospheric pressure and the cars are drawn though this medium by means of motor- driven propellers as on the standard planes. It is the friction of this air that makes higher speeds impossible and it is the removal of the air that was the basis of my original investigations.”

“You are being a little too technical for me,” laughed Doris, “but I think I get a fair idea of what you are talking about. And it really is interesting. How is the rest of it done?”

“By superimposing certain other frequencies on the carrier waves that comprise the tunnel walls. These are the ones I have discovered and am now ready to put to practical use. The first of these causes almost complete evacuation of the interior of the tubes so that the air pressure is negligible. The other is a wave that provides the new propulsive energy for the cars. You see, it will no longer be possible to use the propellers, since there will be no air for these to work on. But my method will draw the cars forward by an inductive action that is capable of providing tremendous speeds. I am afraid I can not describe it to you because it can not be explained without going into great technical detail and that would bore you to extinction. The important thing is that I have my chance at last.”

“Oh Jimmy, I am so glad,” breathed Doris eyes shining with pleasure “and I know you will succeed. I just know it.”
