8 grams of thorium could replace gasoline in cars

Didn't I cover this already?  Yes, I did.

On thing I liked was this pic:

This shows how little Thorium we are talking about, which will be equivalent of 7500 gallons of gasoline.  Impressive, yes?

No.  Thorium is plentiful.  Mining it is no problem at all.   Radioactivity is mild, as you can hold it in your hand, with no ill effects.
