Yes, the centripetal acceleration only starts to get reasonable (ie less than 10g) with a 20km radius centrifuge. The only practical way to do that would be an evacuated circular tunnel equipped with a maglev. Maybe that's their solution?

That's reasonable _for humans_. No one's going to launch a human by this thing, though, I hope.

That's starting to sound like a hyperloop now

Please let him be playing the long game.

Hyperloop, magnets, battery arrays, solar, boring company, etc sounds pretty cool.

It would be pretty cool if Musk was using Hyperloop as a proving ground for technologies to build Hyperlaunch.
