Much cheaper than plane. It will take around 20 dollars from the west to the east.

Well, that's a pipe dream of a price. The electricity required to transport a person by MagLev is horrific in terms of cost per km.  $20 wouldn't even cover the wear and tear on the capsule.

Robert is quite correct, the power consumption and issues with maintaining a vacuum along with other technical issues may well see this train being nothing more than a prototype.  Musk doesn't invent new technologies, he tweaks existing technologies and improves them, this time, however, he's up against various nasty real world issues including parasitic drag, thermal issues, track settlement and it's effect upon the required vacuum "tube" wear and tear, power issues and of course what happens when it all goes very wrong at high speeds.  I'd not be too happy discovering that I was part of a half-ton projectile that's out of control at 1200km/h as you won't be walking away from the sudden deceleration in the last few milliseconds before your ass-hole gets shoved through your brain in a rather violent act of self-destruction.
