Energy storage

To store energy, the engine provides motion to the disc/cylinder, increasing the rotational speed of the flywheel; the kinetic energy can later be drawn by the engine to generate electricity, this way reducing the rotational speed of the flywheel. Several companies are today developing flywheels to use in Formula 1 and motorsport in general
