This video is pure horseshit. It makes speculative claims about energy and technology without having a shred of truth and accuracy in it. Magnetrons are not lasers. Magnetrons don't create energy. Magnetrons do not scale up in size thousands of times and still keep working. And most importantly, magnetrons require a vacuum inside them to work. This is all just sensationalized bullshit designed to get clicks and views for advertising money. Anyone with any real science knowledge does not believe this garbage.
