Part 1 of 2 - Gregor Arturo describes the basic geometry and ratio to construct a rodin coil when using vortex theory, while also introducing his new concept for a motor based off a dodecahedral layout of magnets and a vortex capacitor. The toroid ratio mentioned in the vid is 0.70130161670408 to 1.
This video is somewhat outdated with my current research.
