No it is not. Calculate the outward force of a centrifuge with 300 foot radius with a speed of 3000 MPH at the edge and you get a force of 2000G! Check your o

  At around 50km radius you get 3g. That would be a pretty big centrifuge! Humans will probably never use this but maybe some types of satellites can handle the load.

  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 starting to sound like a hyperloop now

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

      Please let him be playing the long game. Hyperloop, magnets, battery arrays, solar, boring company, etc sounds pretty cool.

    > Yes, the centripetal acceleration only starts to get reasonable (ie less than 10g) That's reasonable _for humans_. No one's going to launch a human by this thing, though, I hope.

  Nevermind that 3,000 MPH is entirely too slow.
