I’d like to add that I think North America needs to invest in making Thorium reactors and/or Fast-Breeder systems portable: Nuclear trains sounds stupid until you realize Thorium exposed by a train crash or maintenance issue cannot emit lethal doses, and Fast Breeder fuel spheres are no more dangerous in a sunken ship at the bottom of the ocean than in the emergency cooling tank of a damaged ship or the reactor of a working one.
I’m going to go find a train tunnel to stand inside of.
