Scientific sorcery? Japan achieves near-frictionless levitation on macroscopic rotor A research team from the Okinawa Institute of Science and Technology (OIST), on Friday, announced that it had ...
Researchers at OIST built a graphite disk that levitates and spins for hours in a vacuum, showing how perfect magnetic symmetry can cancel energy loss.
With a clever design, researchers have solved eddy-current damping in macroscopic levitating systems, paving the way for a ...
