10.4 Moment of Inertia and Rotational Kinetic Energy
Energy in rotational motion is not a new form of energy; rather, it is the energy associated with rotational motion, the same as kinetic energy in translational motion. However, because kinetic energy is given by K = 1 2 m v 2 K = 1 2 m v 2, and velocity is a quantity that is different for every point on a rotating body about an axis, it makes sense to find a …
Energy of a rotating wheel
Let''s say I have a rotating wheel in an empty void which has an angular velocity ω ω, then its total energy will be E = 1 2Iω2 E = 1 2 I ω 2, as the wheel is not moving.

Why can''t we generate electricity from spinning car wheels?
In order to get your wheels turn, you have to provide some amount of energy (obtained from the fuel). If you make electricity from that rotation, it will withdraw energy (and slow the weels). And because no system 100% efficient, some (in fact a lot) of the energy will be lost in the process (as heat).

energy harvesting
Electric motors have the great power of being capable of converting mechanical (rotational) energy in electricity and vice versa, and with a quite high efficiency. But if you need to take the energy from a "linear" movement, like from the surface of a tire, you need a gear which takes the rotation from the movement of the tire, like a dinamo.

In energy storage, the principle of the flywheel can be used. Flywheels store energy in the form of the angular momentum of a spinning mass, called a rotor. The work done to spin the mass is stored in the form of kinetic energy. Video 1 is a simple video that illustrates the concept of flywheel electrical energy storage.
