There is a lot of research going on in magnetic bearings for all sorts
of things, like turbines, flywheels, etc.  Since magnetic bearings are
inherently unstable, you need to use lots of feedback electronics to
make it all work.  Just thinking about our friends in Ingolstadt
putting that on a turbo gives me the shivers...five volumes of Bentley
just devoted to turbo suspension electronics :-)...and lots and lots
of connectors and sensors... :-) :-)
