Galloping conductors in eastern Idaho around Christmastime 1998. Conductor gallop is the high-amplitude, low-frequency oscillation of overhead power lines due to wind.

A vibration in a string is a wave. Resonance causes a vibrating string to produce a sound with constant frequency, i.e. constant pitch. If the length or tension of the string is correctly adjusted, the sound produced is a musical tone. Vibrating strings are the basis of string instruments such as guitars, cellos, and pianos.
According to the team that created the device, the vibrations from the heart muscles would be enough to allow the generator to power a pacemaker. [2] This would eliminate the need to replace the batteries surgically. In 2012 a group at Northwestern University developed a vibration-powered generator out of polymer in the form of a spring.
Tesla's oscillator is a reciprocating electricity generator. Steam would be forced into the oscillator, and exit through a series of ports, pushing a piston up and down that was attached to an armature, causing it to vibrate up and down at high speed, producing electricity.
