I thought Musk said it wasn't an evacuated tube. Does it not count because it's very low air pressure and not a completely hard vacuum?

- lnanek2 13y agoI think it's fair that he said that. A vacuum tube has as little air as possible to help things move. His paper explicitly says it is more cost effective to have some air and his capsule design depends on air as a levitation cushion. If he had said it was a vacuum tube, no one could have guessed the levitation method.
