Kinetic Energy = 1/2 × I × ω^2. To maximize the kinetic energy, the moment of inertia must be optimized. The moment of inertia of a flywheel is given by the formula: I = 1/2 × m × r^2. Where m is the mass of the flywheel and r is the radius of the flywheel. Optimizing the rotor shape and material can significantly impact the moment of
