More excellent analysis from another person who is paying attention and actually knows something about science. Only the ignoramuses (we all know who they are) need to read a book and get a clue.

The space craft as described do have some magical properties...
Maybe. The "burners" derive their energy from fusion as do household power units. Here is what my notes say:
"Fusion Power (desktop)—The UW outlaws any sort of atomic power on Earth, except for large centralized fusion plants run by the government. Off Earth, fusion power units are small and run homes, cars, burners, etc. The units produce electricity via an aneutronic fusion reaction using helium-3 and deuterium as fuel and bismuth as a fusion catalyst."
My recollection is that none of the three materials are radioactive and that they produce no residual radiation during fusion. All the helium-3 and deuterium one could ever want, can be found ... where? (Consider this an exercise for the student.)
