Nice summary.

I have wondered since I first heard of thorium reactor why they weren't already adopted. Since some of the country with the civil nuclear power are those with nuclear weapons, is it possible that the military are lobbying for uranium? (I can see two possible reasons: refining price going down with production scaling, or just to hide their own uranium import in the civil import. If Thorium is adopted worldwide and can't be used to build nuke, seeing who is upgrading its nuclear arsenal would way easier, which can be good or bad, depending on your point of view.)

>The technology development is decades in the future.

Well, that's true for every research domain which isn't funded enough.
