Fusion Reactions: The Expanse
For Fusion Energy Week 2024, we asked ORNL fusion scientists and engineers to react to depictions of fusion energy in pop culture and separate fusion fact from fiction.
In Part Two of the "Fusion Reactions" series, they look at fusion-powered spaceflight in "The Expanse," an epic sci-fi series set hundreds of years in the future, when humans have colonized the solar system thanks to the development of powerful spaceship drives driven by inertial confinement fusion. In the clip, the protagonists aboard The Rocinante encounter an issue with the fuel pellets in their reactor, leaving them stranded on the edges of known space. Our reacting fusioneers look at how realistic the reactor design is, its parallels with real devices here on Earth, and whether the show's chosen fuels of choice - deuterium and helium-3 - would actually work.

The Expanse (Amazon Prime Video) is worth the watch for anyone who enjoys a good space show. While not perfect, the physics in this show are more accurate to real life than most space shows. I think the best example of this is that there is no artificial gravity. They do "make" gravity however by using these very advanced "Epstine Drive" fusion reactors shown in this video. These fictional reactors are capable of producing many G's of thrust for sustained periods. They typically burn at about 1G of acceleration for days/weeks on end to produce "gravity". Half way to their destination and at a very high velocity, they actually cut the burn, flip 180 deg and then decelerate at 1G to their destination. Its this attempt to match real life physics, that makes this show, in my opinion, worth the watch. Especially if you are on this KZread channel reading this comment :) This is basically proof you are a near and are probably proud of it like I am.

The books are excellent as well! They tend to discuss the science (fictional and otherwise) a bit more than the show. The characters are also a bit better fleshed out in the books (in my opinion).

Yeah, The Expanse is one of the best ever science fiction TV series, both from the story and the accuracy of the science. I'm just about done with season 1 Foundation and only watched beyond the 2nd episode to see how much worse [stupider] it would get. It's really _laughably_ bad and a shame to mar such a great book. Won't be watching 2nd season. Just one FFS e.g. is at least two asteroid fields of astonishing density. Did The Expanse ever have one of those? It's almost like a law that a space story have one including flying though it ...OMG still? After all this time they're still doing that crap?
There's a little bit of Naomi Nagata in all of you 👍
