the Sun et al videos

shows the slight movement of the hand held magnets started the rotation that lasted for two minutes in the video and about 17 minutes in real life. There were some movement of the arm. Many objected to this video claiming the rotational energy came from the arm movement.
Video  shows the wheel in the vertical position. No arm movement was needed. A slight initial pull of the wheel allowed continuous motion for about 30 minutes.
Video  shows the wheel in horizontal position again. Magnets wrapped on water bottles were used to change position and orientation. Again, the longest rotation time was about 30 minutes.

Video  and  show the use of an external pulsing coil. The wheel rotates forever or until the parts fell apart so long as there is pulsing current. The next step would be to provide the feedback mechanism such as the Bedini or the Pulse Motor.
Apparently, Steorn, by luck, was able to produce a single resonance system that could rotate for a long time.
