The idea is to get the stock brushless motor from an old CD/DVD drive to power an rc airplane, let's see if it will work. It ...

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 ...
