Flywheel Stocks

Flywheel-based energy storage devices have the capacity to store electric energy as kinetic energy and to generate electric energy from this stored kinetic energy. Flywheel energy storage systems store kinetic energy (i.e. energy produced by motion) by constantly spinning a compact rotor in a low-friction environment. When short-term back-up power is required (i.e. when utility power fluctuates or is lost), the rotor's inertia allows it to continue spinning and the resulting kinetic energy is converted to electricity.
