Thanks for the alert..I see that Stefan has already cast doubt on it in his comments under the video. Here's the English titled similar video from February: [youtube]-ossxHUeup8[/youtube] So, what is it ? B field, Lasersaber influenced, sort of high ohm in series, air coiled motor ? How can it spin up in seeming stages ? How does it spin up in such a way, from a very slight rotation when the rotor is placed inside the coil circle ? Without ferrite or some other core, there's nothing to 'kick' such a heavy rotor into movement. There's also no speed governor, except the rotor mass, which it evidently has no trouble spinning up to that speed. Am looking at the date on the forum now, though it's still March 31st here
