  • $\begingroup$ But fusion power is also unreliable now, which means all the future space stuff OP wants might not come to fruition. $\endgroup$ Commented Sep 13, 2019 at 22:06

    $\begingroup$ @fredsbend Why would fusion power be unreliable? Fusion depends on internuclear collisions, rather than neutron flux, so slowing neutrons and forcing them to emit their energy as photons actually makes fusion power more usable, because you don't have to have blankets of low-density material to capture high-energy neutrons. $\endgroup$ Commented Sep 13, 2019 at 22:10
  • $\begingroup$ I meant fission. Autocorrect fubar. We're currently using fission reactors in many of our massive war machines. $\endgroup$ Commented Sep 13, 2019 at 22:13
  • $\begingroup$ Stable and safe fusion would have to be invented concurrently, to replace the unreliable fission. $\endgroup$ Commented Sep 13, 2019 at 22:15

    $\begingroup$ We have fusion bombs now. That's what thermonuclear weapons are. They require a fission initiator. $\endgroup$ Commented Sep 13, 2019 at 22:18
