First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass.OverviewFlywheel energy storage (FES) works by accelerating a rotor () to a very high speed and maintaining the energy in the system as . When energy is extracted from the system, the flywheel's r. .

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding. .

The two towers are linked via three , each holding a 225 , totalling to 675 kW of wind power capacity. Each of these turbines measure 29 m (95 ft) in diameter, and is aligned north, which is the direction from which air from the blows in. The -shaped buildings on either side are designed to wind through the gap to provide accelerated wind passing through the turbines. This was confirmed by tests, which showed that the bui. [pdf]
