Evacuated Tube Transport could take you to China in two hours

Click on a label to read posts from that part of the world.

I don't understand the negativity of some of these posters. This sounds like a great idea. By evacuated I believe they will lower pressure in tube to reduce friction with air while suspending and propelling the car using moving magnetic fields. The curve issue can be solved by making the curves full arc over a great distance minimizing g forces. If everyone though like you folks our wheels might have been square. Punching out.

The energy cost of establishing and maintaining a vacuum in such a large volume, with such an extremely large surface area (the vacuum boundary,) is so exhorbitant as to make this approach utterly foolish. (In Fantasy Land though, you could do it.) Similar engineering economics make magnetic levitation financially untenable as well. If you'd like though, go ahead and complain about reading honest feedback on it, or defend it, or advocate it if you like.
Fools like Daryl Oster are camouflage for the real innovators developing solutions that work.
