Thorium Molten Salt Reactors. I wonder if they sound good?

I just watched this video (it's a good channel if you don't know it BTW) and thought I'd post it up given the recent conversations on alternative power sources for cars. On the face of it, it certainly looks like a potentially workable solution held back by politics and profit... I've also been replaying Fallout 4 so I'm kinda biased at the moment...

Thorium reactors have been going to save the world for years, not much has happened.
