Where is the mechanical energy of a flywheel stored

Photo: A typical modern flywheel doesn't even look like a wheel! It consists of a spinning carbon-fiber cylinder mounted inside a very sturdy container, which is designed to stop any high-speed fragments if the rotor should break. Flywheels like this have an electric motor and/or. . Flywheels are relatively simple technology withlots of plus points compared to rivals such as rechargeable batteries: in terms of initial cost and ongoingmaintenance, they work out cheaper,. [pdf]
