flywheel
flywheel flywheel n. A heavy wheel or disk which stores kinetic energy by rotating on a shaft, and by its momentum smoothes the operation of a reciprocating engine by reducing fluctuations of speed. It is used in certain types of machinery, such as automobiles. [WordNet 1.5 +PJC]

Note: Flywheels rotating at high speed have also been proposed as a means to store kinetic energy for use as a low-polluting source of energy in vehicles. [PJC]
