Benefits of technology

[0011]Thus, the present invention having a simple structure stores the mechanical energy first, and rapidly generates electricity by circulating the gas through controlling of the control valve of the gas from the reservoir, minimizing the mechanical loss and maximizing generating efficiency.

[0052]The advantages of the present invention are: (1) the mechanical energy storage system and method are simple and powerful in harvesting and converting mechanical energy; and (2) the mechanical energy storage system and method has a short reaction time.

Problems solved by technology

The flywheel energy-storing technology includes highly precise components for storing kinetic energy, and has technological difficulty in obtaining vacuum, superconducting magnetic-levitating contact-less bearing, and flywheel enduring high-speed rotation in order to increase the energy density.

Also, in order to be used to harvest energy from various sources, miniaturization of the technology is essential, but the above flywheel energy-storing technology has to be developed much more and has problems in order to be used as a miniaturized and efficient energy-storing device.

Therefore, there is a limit for it to store directly various mechanical energy generated from various physical phenomena.
