Abstract
One or more permanent magnets, or one or more permanent magnet arrays are used to produce shear force levitation. A primary application of shear force levitators is a levitated ring energy storage device. Such a levitated ring energy storage device includes a round support structure having a first magnetic levitator or levitator array encircling its outer periphery, and a ring encircling the support structure and having a second magnetic levitator or levitator array encircling its inner periphery, such that the first and second magnetic levitators (or levitator arrays) interact to produce a vertical force that levitates the ring.
