Add a comment. For "many many rotations", a pneumatic motor can act as both a compressor and motor. Spinning the motor causes air to be forced through a tube, one-way valve, and storage tank. Opening the valve allows the compressed air in the tank (potential energy) to flow back through the tube and motor, spinning it in reverse.

A properly tuned pendulum vibration harvester can significantly reduce vibration and harvest energy at the same time [ 22 ]. However, when the ambient frequency changes or the device''s own natural frequency deviates from the ambient frequency, the energy harvesting efficiency will drop significantly [ 23 ].
SPRINGS. When w inding up a coiled watch spring (spiral torsion spring) the energy is stored and slowly released, providing power to the watch mechanism. This is basically the same mechanism that provides power to wind-up radios, timers and some torches. Spring steel is often used to manufacture the spiral torsion spring.
