Hyperloop CAN be realistically built.

But not with our current technology.

First we need to get regular maglevs on working order and then we can begin thinking on vaccum sealing them.

And then it probably will not make a difference, Hell, the amount of concrete needed may very well offset the energy consumption. Nevermind the issue of a single guy with a drill being able to stop the whole line (and maybe cause a big incident if a train happens to just be going through.)

I mean technically they can be built. But never. And I mean never they would be viable or realistic.

To see why just look at this: https://www.youtube.com/watch?v=Zz95_VvTxZM one guy with a hammer could trigger this and destroy killometers of tracks.

Obviously, the containment would be built out of concrete.

Otherwise it would be impossible, it would collapse on itself by stress alone rather quickly.

Anyway, my point is that Hyperloop is like wanting to make the concorde without making the 707 first.

And it may very well like the concorde end up being not practical.

Frankly, I don't see the need to be faster than 400km/h . That's what videoconferences are for

Obviously? Because none of the efforts or whitepaper tried that ...

Nobody is suggesting you build it with the materials of a thin pressure vessel .

Literally what Musk's whitepaper suggested.

I'm pretty sure that even that whitepaper doesn't suggest something that is meant to resist inward pressure instead of outward pressure
