Strange source aside I’ve been hearing were on the edge of a breakthrough for thorium reactors and cold fusion for 40 years now.
If China had it working already then we would have heard it a lot louder from them.
Things that don’t exist yet aren’t a solution for problems we have now.
It’s not like we could now just build a thorium reactor that makes economic sense without decades of serious prototyping. And by that time we might have found that there are more pbolems with it than we thought.
