    NASA G2 flywheel. Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy.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 ...

    Because there are some inefficiencies with this method, there is a certain car company (at least the one i guess) that uses a combination of flywheels at different RPMs to attain the same effect - how does that work? Charlieb000 17:15, 2 April 2015 (UTC) A flywheel is axially balanced (it's a symmetrical wheel).

    Dual-mass flywheel section. A dual-mass flywheel (DMF or DMFW) is a rotating mechanical device that is used to provide continuous energy (rotational energy) in systems where the energy source is not continuous, the same way as a conventional flywheel acts, but damping any violent variation of torque or revolutions that could cause an unwanted vibration.
