What's a suitable energy storage method for slow rotary motion?
For slow motion, the pneumatic motor may leak and store little or no energy. For "many many many rotations", a permanent magnet motor /generator -> DC rectifier -> battery (or supercapacitor) may work to store considerably more energy.
How does a spring store and release energy?
With a normal spring, you store energy by compressing it using a linear force, and it releases that energy by decompressing and exerting a linear force. The question is, is there a mechanical mechanism that stores energy by rotating force and releases it by rotating force?
Can a rotary motor store more energy?
For fast rotary motion, a rotary motor could work to store energy, but for slow motion, a pneumatic motor may 'leak' and store little or no energy. For 'many many many rotations', a permanent magnet motor/generator -> DC rectifier -> battery (or supercapacitor) may work to store considerably more energy than a linear motor.
What is a flywheel energy storage system?
First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass. To reduce friction, magnetic bearings are sometimes used instead of mechanical bearings.
What is the energy storage mechanism in old windup watches?
Most likely, the energy storage mechanism in old windup watches is a coil spring. The coil spring can be designed for a number of rotations, generally with a lower spring constant.
What happens when energy is extracted from a system?
When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the flywheel.
