Flywheel Storage Systems

The simple concept is the momentary storage of the kinetic energy from the engine in revving up the flywheel as the vehicle decelerates instead of depleting it as heat in the brake pads. This energy would allow modern cars to disengage the engine for long waits (idling at a traffic light, for example) and be stored in flywheels mounted on drive

Could Flywheels Be the Future of Energy Storage?

These systems work by having the electric motor accelerate the rotor to high speeds, effectively converting the original electrical energy into a stored form of rotational energy (i.e., angular momentum).
