Hyperloop the train of the future?

[Adrien (ex-nico239)]

Technically it should be possible but at what cost and how profitable?

So in the end with what reality?

Point of view of an expert Hyperloop: formidable technical-intellectual swindle

HYPERLOOP: THE PARADOXES OF A "REVOLUTION" https://lvsl.fr/hyperloop-les-paradoxes-dune-revolution

If the companies involved in this race will probably find, as mentioned above, emergency relief in case of failure of Hyperloop projects, it will probably not be the same for communities that have largely subsidized missing projects, which will potentially be found with useless infrastructures on their territories, and which risks big with the departure of these startups. In Toulouse, for example, Hyperloop TT was greeted with great fanfare and is today at the heart of a new innovation zone centered on the transport of tomorrow, in which it has been sold large areas. If its arrival was beneficial for the image and the territorial attractiveness of the city and this new area of ​​Francazal, its departure in case of redemption or bankruptcy could be conversely very negative and deconstruct a process being polarized territorial innovation ...

Since speed benefits the better-off, investing in the latter is done to the detriment of the most disadvantaged. The risk is therefore to develop a fundamentally unequal transportation under the guise of a revolution in the world of transport ....

If the hyperloop is a scam then what is it?

(...)
The speed of the video may be slowed down, but the vehicle is still invisible. In a video posted on Facebook's September 6 2019, the Air Force Test Center, the US Air Force's dedicated research and development subsidiary, introduced a craft capable of achieving supersonic speed.

A sleigh that runs at 10.620 kilometers per hour
The test was carried out on a test track located at the Holloman Air Force Base, a US Air Force base in the southern United States. Little information has been communicated about this test: what means of propulsion to reach such a speed? What is the objective of this test? The Air Force Test Center however gladly gave the speed reached by this sled placed on rails: Mach 8,6 (Mach 1 corresponds to the "Sound barrier") or exactly 10.620 kilometers per hour!

What power is needed?
How are the friction of the air reduced?

[Leo Maximus]

"Hyperloop's first commercial line, developed by one of the private companies that took an interest in the project, could see the light of day in 2020 if the enthusiasm for this technology continues."
2020 is over in less than 7 months Where is the Paris-Marseille line?

The craze is enormous, money is flowing freely. Result? Nothing

Beware of ads. We also had a similar train in the 60s, the aerotrain, 430 km / h. Here is what remains of its track:



The problem with all these devices is the necessary ground infrastructure.

Like the TGV ... when you want it to go fast.
The aerotrain was a brilliant idea torpedoed by politicians and the oil crisis because it operated on kerosene.

Ps: The track you are talking about was a test track. Normal that it remains in the state.

[Leo Maximus]

The Aerotrain was not that utopian, but the problem was that it had to transport its fuel. Over long distances, tank cars on air cushions would also have been required. And we imagine a jet engine arriving at a station in Montparnasse or Austerlitz with noise and polluting discharges in the city? Even without the oil crisis the Aerotrain was doomed.

The Aerotrain has an heir, with the same type of low-cost route, the principle of the air cushion, and hydrogen instead of kerosene: https://space-train.fr/ Propulsion by hydrogen turbines ... What future ?

I think we should rather look for explanations in the noise and the cost of the rails ... in addition to consumption and inevitably monstrous pollution: at 500 km / h on the ground a reactor does not perform well. .

In short, he accumulated the flaws !! Hyperloop shares some of them!

The "aeronautical" performances were not so good: the TGV did much better a few years later ...

[Leo Maximus]

... I think we should rather look for explanations in the noise and the cost of the rails ...

The cost of the rails? No. The cost per km of the Aérotrain route is low, probably much lower than that of a TGV.

Precast concrete elements can be installed very quickly. No endless and expensive work.

Ditto for the relatively low environmental impact (for the track, I specify ), in addition no level crossing.

It was its engine principle that killed the Aerotrain.

[Christophe]

Yes you are right and this is what is indicated in the article (which I read after ) and no maintenance cost ...

An LGV is a financial pit ... as much in construction as in maintenance ...
