It's all about orgone energy or equivalent concepts (Vril etc.).
The authors literally pulled names and concepts from orgone theories.
>Orgone was seen as a massless, omnipresent substance, similar to luminiferous aether, but more closely associated with living energy than with inert matter. It could allegedly coalesce to create organization on all scales, from the smallest microscopic units—called "bions" in orgone theory—to macroscopic structures like organisms, clouds, or even galaxies.
Orgone is literally called "spiral energy" or defined as "screw-shaped" in some sources.
For what concerns FFVII, the "cloudbuster" was a machine built by Willy Ley (the one who came up with the Ley-Lines concept) as an attempt to control weather.
The Anime world is full of people into esoterism at a level that is mind-blowing.
