Aug 10, 2016 at 10:20 comment added tobiasvl The interstellar generation ship bound for Tau Ceti was not supposed to continuously burn like the other Epstein drive outfitted ships in the series (which accelerate for half the journey, flip, and then decelerate) – it was instead designed to burn until it reached a certain speed, cut the drive, and then spin up the main section of the ship to create centrifugal "gravity".

Jul 19, 2016 at 1:12 comment added Hypnosifl Well, the page on the nuclear salt water reaction engine does preface the idea of 90% enriched uranium by saying "Zubrin then goes on to speculate about a more advanced version of the NSWR, suitable for insterstellar travel." Maybe I was too hasty in ruling out antimatter on the basis of interstellar travel (I'll edit that line), but it still seems like a ridiculously advanced technology given what I've seen in summaries of the overall tech level of The Expanse series.
