Thank you, the young man has a passion for this and good skills ,it is good to see.
Hopefully he has a very bright future .

He seems unaware of his achievement [questions his success because it stops] ,but he is aware of how to make it much better
hopefully it is a sincere presentation  ?

just proving what he has shown would be quite amazing indeed !

thanks

Interesting video and looks like he put a lot of time and effort into this but the obvious question is if he had just taken a heavy Metal disc without any magnets and stuck a shaft through the middle then provided the same amount of force to spin it, would the metal disk have spun longer ?

 Oddly snuff
I wonder if his heartbeat (thru his firm pressing hand) could be contributing to this in some way ?

He might not even be aware ?? He has soo much loss in the systems wiggly design...(he does know this)
Yes a nice clean bearing on a precision machined  shaft with similar weight would spin for half an hour.

But that's not what's going on here,it obviously stops rather quickly when it doesn't sink up..

Could also be some mechanical ossilation contributing  ?
Perhaps Stefan can ask him to add a few variants to the test,as I saw he mentioned heat ?
That would be good to see?

Of course, some of us are truly cheering for the young man!!

Congratulations! An excellent demonstration of the fact that a heavy rotor on good bearings can spin for quite a while, and that clever video editing can make this time seem even longer than it really is!

Good find on the video.
Points of interest for me are the bloch wall magnets facing the full polarity of the other magnets. Looks similar to the Howard Johnson design. The wobble of the rotor may help create a necessary imbalance. He shows good details on how he built it.

Points of less interest. I understand the video editing while he's talking into the camera but I'd like to see none of it during the actual demonstration. A run up test of a rotor with and without magnets would be nice to see which one spins longer and which one provides more force while spinning.
