In this “starship style coil” he gives credit to someone named Rich Motzer.  A lot of these neat efficient energy experiments get inspirtation from different sources.  Here is a continuation of what he had to say:

Thanks to Rich Motzer as well for discovering how to make the Starship type coil and save us a lot of time in the winding efforts. The 147258361 winding pattern round the octahedral figure yields strong magnetic fields and energies in the central area that I’m still exploring. The one inch diameter neodymium cylinder magnet is magnetized thru the diameter. It goes 10 to 12,000 RPM with rather strong troque from just a small +12volt brick power source

Have you seen a lot of these types of devices before?  If so which is your favorite one?

And if you think there is an efficient energy secret in one of these feel free to comment.
