Awesome! I had not seen that experiment before. I think over-unity is just a bi-product of understand what exactly electromagnetism is, and which this experiment provides some very good clues. It is similar to The Good Vibrations channel in which he shows that magnets involves a rotation of a "dielectric" or non-spatial medium. I think the Rodin coil, or any coil in general, is a way of directing the "dielectric" in a much more controlled and engineered pathway than typical magnets. I will be focusing on electromagnetism experiments starting next the beginning of next year so stay tuned as I got some epic experiments to test out!
PS: Thanks for the shout-out to my vortex math video!
