They are more fuel efficient than anything physics predicts is possible because they effectively have the max thrust of chemical rockets, combined with a nearly infinite ISP from using no reaction mass. They mention refueling the fusion reactors and the steam thrusters, but they never mention reaction mass for the Epstein drives.
- colordrops 10y agoI did some searching and found this: https://m.reddit.com/r/TheExpanse/comments/4frz1k/epstein_drive_may_be_real/ https://m.reddit.com/r/TheExpanse/comments/4frz1k/epstein_dr... Ignore the original story and the top level comments. Seems there is some evidence of reaction mass. There is some interesting analysis and basic math in the comments. I didn't see anything that confirmed or precluded the epstein drive from being possible. I should get out a pen and paper and work it out myself.
