a ring of superconducting material rotating up to 6 500 times a minute

The magnets mounted on a bicycle wheel in my laboratory were headed toward this. Just a matter of rotating a hundred times faster and dropping the temperature four hundred degrees, and a few other minor details. There is a time for Michael Faraday, and this could be be that time.

Stupid question department:

If I have a charge being conducted through a rotating superconductor, is there a rotational speed at which that charge is actually static?

I'm going to propose that we take the LIGO gravitational laboratory at Hanford and spin it at 6,500 RPM. Should be worth a fair NSF grant.
