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.
