Except the concept is already “proven” in that regard. What the issues are with it, are the same as with everything techy that needs to make it in the world - scaling it up.
It’s impossible to hold a vacuum in a tube that’s hundreds of kilometers long. It is impossible to build a vacuum tube that doesn’t suffer because of thermal expansion. It is impossible to build that long of a tube and it not have a single dent in it across the entire way. Even if you somehow ignore physics, people don’t need a train like this. There is flights. Travelling at reasonable speed has been proven for hundreds of years.
To explain it in a tldr way, I can grab a straw, put a wet tissue inside it, blow on it and in relative speeds it would go incredibly fast. Yet nobody would go for trying that with a train, since scaling it is impossible.
Science isn’t just theory. Actually building stuff teaches us a lot of things, and there isn’t really any other way to advance fields like materials science without hands on experiments
sometimes proving stuff with science is still worthwhile though, right?
