This article never even mentions the fundamental attributes of the proposed Hyperloop. Hyperloop is not magnetic levitation. Hyperloop is not a vacuum tube.
It's a low pressure air ski. It is meant to be substantially easier to engineer than the tolerances required for something like maglev in a vacuum tube. Whether that will be true hasn't been shown.
But Hyperloop is not maglev, it's not a hard vacuum, and it's not necessarily supposed to be superior to maglev in vacuum tube, except that it is meant to be cheaper.

- netizen-936824 5y agoSince when is it not a vacuum
- jlmorton 5y agoSince it was first proposed [1], it was not a vacuum, and the original paper spends a lot of effort to distinguish a low-pressure tube from a vacuum. The design not only is not a vacuum, but relies on it not being a vacuum for propulsion. To be sure, it's extremely low pressure, with a pressure lower than Mars. But it is not a vacuum.
