Flywheel energy storage
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 …

China''s electric car scientists create powerful electromagnetic catapult for aircraft carriers
In comparison, traditional aircraft carrier electromagnetic catapult systems typically require more than three seconds to accelerate a 13-tonne fighter aircraft to 66 metres per second. The new device can also bring an aircraft approaching at 72 metres per second to a full stop in 2.6 seconds, fully meeting the military''s requirements.
