>>2243950There's no transparent material strong enough to make a huge, 500km plus vacuum chamber with, steel would have to be used.
Impossible to create a still tube that big, welding smaller sections is not feasible because welds would break due thermal expansion. Using joins would be a maintenance nightmare.
Any breach in the vacuum chamber would cause a deadly shockwave that'd kill anyone in the tube.

>>2243972Lay off the Musk personality cult please. I like Tesla and what SpaceX is doing with rockets, but thinking the Hyperloop will ever be made is ridiculous.
