Vertical Mendocino Motor: each face of solar cell is connected to a coil of copper wire. Spins fast and quite in a sunny window. As the rotor turns each solar cell takes a turn in the brightest light, which provides electric current to one of the coils which becomes a temporary electromagnet that pushes against the permanent magnet configuration in the center- propelling the rotor to rotate. The rotor assembly is nicely symmetric and balances on a sharp point for minimal friction. Invented in the 1960s by Daryl Chapin of Bell Labs and popularized by Larry Springs of Mendocino CA

Pisces Kinetic Art Lamp: standing waves of a rotating string are illuminated by strobing light in this new kinetic sculpture by artist and computer engineer Stephen Co. With the help of programmable micro-controllers, strips of addressable RBG LEDs are made to flash in sequences that make the rotating string change colors, merge into spoon shaped surfaces, or split into multiple braids. The string is propelled by small motors and the standing waves can have multiple nodes, which can be altered by touching the string while in motion.

With sufficient velocity the surface normal force supplies the centripetal acceleration. The car’s battery last for many minutes and is USB rechargeable.
