[Spaceships] Reactionless Drives, Pseudovelocity, and NOT breaking a setting (much)

We must not be picturing the same thing. In the limit you can do exactly the same trick as with the potential energy teleport scheme upthread, use the drive to accelerate, turn it off and pull out the energy.

On the more general issue, I'm uncertain where we are looking at this differently. Are you imagining a preferred frame? A pseudovelocity (or for that matter teleport) scheme can look less abusable that way - the sub-relativisitic etheric speed limit part certainly suggests that - having the ether as a preferred frame. Though it doesn't make the potential energy issue go away.
