Laminated rolls of carbon fiber spinning at high RPM on magnetic bearings have been the state of the hype for terrestrial flywheel power applications for the last 13 years: http://www.wired.com/wired/archive/8.05/flywheel.html Magnetic bearings have been used in fans, and I'm familiar with a bearing-analogous application in Inductrack maglev trains as well. Has this type of tech penetrated into aerospace?
