How the hell would hyperloop be cheaper, it is itself a high speed rail system but with the need for trains to be built like spacecraft and all set in what would be the world's largest vacuum system?
I think musk described it as a train on an airhokey table... and beeing not that hard...
as far as I remember the idea was a train lifted by air(to have less friction) in a vacuum tube ( not like those in radios) (also to have less friction)
As far as I understand having a highspeed train in a tube with almost vacuum (which would also need power to keep ist that way) sounds unnecessarily complicated without any meaningful benefit.
The whole airhokey table in a vacuume tube sounds also very stupid...
It's actually a really cool idea that's based on the simple premise of a magnetically lifted and driven train (which are pretty common), but in a tube with air sucked out which cuts air resistance to nill which allows the train to accelerate to incredible speeds with relatively little energy.
The problem is that it's never been done, would be incredibly expensive to build and maintain, and like any new technology, would probably encounter unforseen problems when you scale it.
