Review : Assemble your own Mendocino Solar Motor

Although its operating principle is really very simple, the first time you see a solar-powered​ Mendocino motor you can’t help being fascinated. It looks like it came out of a wizard’s den — hovering in mid-air and spinning on its own, apparently without any source of energy. The ​magnetically levitated electric motor, named after the Mendocino County in California, is powered by solar cells. It uses a rotor suspended on low-friction magnetic bearings.
