99 Years Later... We Solved It

Physics Girl - have watched you for awhile and just subscribed!

I am curious if you have seen the recent interview of Salvatore Pais - who applied for patents for some potentially physics breaking technology for the Navy.  
He was interviewed about his peer reviewed papers on Theories of Everything w Curt Jaimungal (YouTuber w a film and physics background).  
There are several topics, including an anti-gravity engine with plasma (apologies if I have described it incorrectly). 
At any rate, would love to hear your take on the physics discussed...
