Anybody yet considered using this method of "spinning" the GG?

I guess there would be no noise and it could "float" between 2 magnetic annulus'? I have absolutely NO idea how it WOULD be fabricated . .but just seems a dead ringer for this type of work.

Failing that, how about a magnetic linear device that would wobble the GG?

Any takers?

. . but what do I know . .

Grazie
