Funny you should ask.
I'm halfway through this, the best backgrounder on Thorium I've found. I've already learnt a number of novel concepts. E=MC^2 is a dog-whistle. Geothermal power produces brine and 10% of that can't be reinjected and it's radioactive.
Where they go wrong is saying heavy elements are created in the center of the Sun, not on it's surface, and calling an electrical plasma 'wind'.
It's noon, I need to get outside. I'll watch the rest later.
edit:
I'm sold. At 57:46 Alvin Weinberg says desalination was his impetus. At 7:59-9:00, very impressive highlighting of the text as it's read. Wish they all would do it this way.
What do all y'all think?
