Claim:
1. A method comprising: providing an air-moving assembly, the air-moving assembly comprising: coupling at least one flywheel to the shaft of the air-moving assembly, with the one or more mechanical fans coupled to the shaft between the motor and the at least one flywheel, the at least one flywheel storing energy during motor operation, and facilitating, for a specified period of time, continued rotation of the shaft during interruption in power to the motor; providing a motor decoupling mechanism coupled to the shaft between the motor and the one or more mechanical fans, the motor decoupling mechanism comprising a clutch coupling the shaft to drive a shaft of the motor, the drive shaft driving rotation of the shaft when the motor is operating and the clutch automatically decoupling the shaft from the drive shaft during interruption in power to the motor; and providing a belt drive assembly coupling one flywheel of the at least one flywheel to the shaft, wherein the belt drive assembly includes a gearing mechanism providing an increased rotational speed to the one flywheel in comparison with a rotational speed of the shaft when rotatably driven by the motor, wherein the specified period of time is provided by the at least one flywheel being sized, and the increased rotational speed being selected, to achieve a set time period from a utility power interruption to the motor for the continued rotation of the shaft at a specified percentage, or greater, rotational speed of the shaft compared with the rotational speed of the shaft when rotatably driven by the motor.
