The alternative is not fossil fuels, that's arguing a strawman, it is renewables.

That is a very cavalier way of looking at it. This is the radiation fallout map from Chernobyl. In all darker red areas you still have to radiation test wild game and people are advised to not each too much mushrooms. https://3.b

All depends on if the cargo is volume limited or weight limited. You don't have to solve every single problem at first even though it would of course be better.

Pitting nuclear against coal is fighting a straw man. The alternative is renewables. With a tiny fraction of the negative side-effects either nuclear or of fossil energy brings.

There's no significant advantage of Thorium from a fuel standpoint. Breeder reactors also essentially give you the possibility of producing nuclear weapons so quite the political and ethical threshold to pass before they would exist in

Now count the combined energy of the global wind or total solar irradiation. Further adding cost to the already most expensive energy source to extract trace amounts of fuel is nonsensical.

Great that the alternative is renewables then!
