Interesting that they spun the superconductor at 6500rpm.

This is well within the operating range of many car engines.

I would have expected the rotation to have had to been much faster...

Last time I heard of some weird results of spinning superconductors was from Podkletnov. He claimed to see gravity reduction of 2% above the superconductor.

The hard drive on my computer spins at 7200rpm. 6500rpm is therefore no big deal.

17 mile circumference X 6500 revs/min = 110,500 mi/min

6,630,000 mi/hr
