SF to NY in 45 Minutes? Evacuated Tube Transport.
- bediger4000 13y agoHow do you draw a vacuum over that much volume? How much effort is required to keep a vacuum over that much volume? Do you have to inspect every single joint (which I assume would be welded) for air-tightness? How do you keep the tubular structure from buckling? Do you have buckle-arrestors every so often along the length?
