This technology has been proposed for some time for use on wind turbines as frictionless bearings. I am not sure why they are not in common use yet. http://www

  It requires a complex, expensive, sensitive, tuned control system with more parts and a decent amount of cpu power. Also, they're subject to axial translation. And it saves friction, not energy, so the benefit is maintenance, si it's only ptavtical in some apps. Still as the systems get more predictable they're finding their way into more applications...
