And even maglev is barely done because it’s so expensive to build. Hyperloop is wrapping that same maglev train into a tube that should maintain a vacuum for kms on end, and pretty much every failure mode would end up being genuinely catastrophic.
Plus you would have to armor the whole thing and spend a bunch on security because one guy with a .50 rifle or some explosives could destroy a whole section and close the whole thing by punching one hole in it.
Haha, yeah. Remember the chaos when militia guys started shooting at transformers in substations? Every hick with a gun would be shooting at it just to shut it down.
The vacuum is the hard part, not the maglev. You would need to enclose the entire track inside if a vacuum, and that world be ridiculously expensive and practically impossible with current technology. It’s already very expensive to build a tunnel for a train, which is why they are avoided if possible. But this would need to be all tunnel that is air tight, so even more expensive than regular train tunnels.
To put it into perspective, the current largest manmade vacuum chamber is at a NASA research facility in Ohio. It’s a cylinder with a diameter of 100 feet and a height of 122 feet. If this were laid on its side, about 1.5 New York subway cars could fit inside. The largest vacuum ever made can barely fit the vehicle inside, let alone allow it to travel between two different places where the extra speeds would be warranted.
The drag is air against the whole body of the train, so you need vacuum everywhere.
Assuming that you could build such a big vacuum there would be safety concerns. What if there’s an accident in the tube? Does everyone in the train depressurize and die? Assuming people can survive and get out of the train car, now they’re in a tube that’s 100 miles long. How can you build emergency exits in a system designed to be as airtight as possible?
So Japan has had maglev since the 90s. Explain?
Their Maglevs are not Hyperloops…
Obviously
I’m aware. That wasn’t the question
It is the answer to your question tho. Maglev is feasible, Hyperloop, not so much.

They gave you the only answer your stupid question deserves.
Oh name calling. How very thoughtful of you.
Clearly very smert
Maglev=! Vacuum. Elon promised an existing technology inside a vacuum.
I know

That kinda puts it in perspective. What about particular vaccum? Or just where the tracks meet the train. That’s the only bit with drag ?

Of course. What a thiccy
