I believe that if the EmDrive produces real force its top speeds are, in a vacuum, only limited by relativity and the amount of energy it can carry.

  That's true of any propulsion system, isn't it?

    yeah

    No, most other systems run out of reaction mass first. With this and a good fission reactor you are halfway to everywhere.

      So I don't get any points for E = mc² ? :) In all seriousness though, I was noting the parallel "limited by … the amount of energy it can carry" and "limited by the amount of mass it can carry" in the sense that, yeah, you're going to be limited by what you can take with you.

    No, real propulsion systems also require propellent
