Remember when he made a video how nonsensical it is to land a rocket? No?

That's because he took the video down. Silently.

His take on Hyperloop only highlights his financially induced hate boner against Musk.

How many times in the video does he point out the rust on the tube? Like 5 times? Light rust. On a non-humanrated test track.

Also he points out again and again the problem of thermal expansion and that omega joints obviously can't work. So Hyperloop can't work.

But he is a nuclear physicist. So the knows that bellow joints exists. He just chose to deliberately mislead his audience.
