Wasn’t that Musks failed hyperloop thing?
I do have to admit the idea is pretty cool though. Not sure how they could be used practically for anything that would justify the cost though. Like cargo transit? At least then you can cut more safety requirements compared to human passengers. But then you have the question of why go to that effort to move cargo faster than a train anyway








What reason is it stated 106 to 100 is optimal, and is that optimal or just what it actually is? Why would the other way really matter much.
You are making a statement with no reasoning behind it.
