And what’s the point of all this?
Here's the link to explain the Bell as simply a centrifuge for the bomb project:
This is probably the all-round best explanation of the Bell, anywhere.
I confess that even the 'dumbed down' scientific explanations in this are heavy going for me. The take-away is that yes, there was some super secret sh-t going on connected to the German A-Bomb project (this bell thing had the highest known war priority and secrecy classification in Nazi Germany, which by itself is notable), but there's not much to support flying saucer bases in Antarctica, time machines or Adolf kneading coconut oil onto Eva's hard-to-get-at bits by a pool in Buenos Aires.
