Spin me that fast and it will probably take me 10 years to return to normal and be able to walk again.
I wonder at what velocity the surface furthest away from the axis of spin might be going? It is known that the higher the velocity, the higher the mass... so at what point does the mass of the particle increase? Or at the very least when is it pulled apart by centrifugal force?
Realize, a tiny object that is spinning at extreme rpm, would be storing a lot of kinetic energy! That is IMHO the battery solution of the future: a micro-flywheel suspended w/ (permanent) magnets (in vacuum) spinning at extreme rpm (in a small battery size device)!
So how did they measure the rotation speed? That’s just as interesting a subject, yet no mention of how it is done.

Had a much larger version under a glass bulb, with 4 sails, each sail about 1cm x 1cm black on one side & white on the other. The four sails mounted on a central mast that perched on a glass post. Spun at a slow 5-10 rpm in full sunlight, but only cost $10
Question is, two silicon nano particles can spin at 50 million times per second with out feeling the effect of centripetal force? Even in a vacuum? We can see things like this in space. But, it's usually one object that contributes to the gravitational pull. How can they continue their cohesive bond?

V = Omega * r. If those are 100nm particles and Omega = 300 billion rpm / 60 s/min then V = 500 m/s. Fast, but not relativistically fast.

Just wondering if anyone thought to check for micro gravitational wave output or incident synchrotron radiation as a by product?

Seems like this technique could also be used as indirect evidence of quantized time. If you reach a point in which the rpms reach a maximum limit, it could be indicative of a fundamental speed limit of time. Of course they do have a ways to go. 300 Billion RPM is about one rotation per 5 nanoseconds. Just 35 orders of magnitude later you reach planck time. Keep at it guys!

Although Crooke, the inventor of the Crooke’s radiometer (the spiny vacuum thing Bob Flint mentioned) also Thought that radiation pressure was the answer, in fact it was thermal transpiration. In other words it’s heat, not quantum photons causing the veins to move.
