Self spining magnet rotor.

Here's a self spining magnet rotor:

Facepalm. It is NOT self-spinning, he is pumping it with the handheld stator.

I wonder how many times a day someone playing with magnets re-invents the Minato Motor.

This is a neat implementation of the autokinetic effect, but all of the rotation of the thing comes from the input of Mister Hand. With these kinds of devices just the effort of trying to hold the stator magnet still will be enough to cause pumping of energy into the rotor. Mount the stator to a rigid mount and no matter where you put it, the rotor will stop rotating.

The guy gets a point or two for his enthusiasm, but he gets points off for the political agenda and the self-hypnosis... and the evident lack of background research.

Gahh.... This time I won't even link to _my_ video of a Minato motor pumped by the stator motion.

ETA: The true Minato motor, the patented version, uses repulsion between the stator and rotor magnets. I think the "ice cream" motor uses attraction, so you have to be careful not to get too close or the "ice cream" will get pulled up into the "cone" stator, as you see in the video.

and here's my current favorite: notice how little push from Mr Hand is needed to get the spinner going:

Ah yes, the "minato motor."   It just won't die!

why do these things keep coming back.
Now Sterling is reviving the new Fast Freddy as well.
