Abstract: A power generating system utilizes rotational inertia forces of a pair of fly wheels fitted with friction-type driving devices to keep the fly wheels accelerating and rotating and to output power to do work. Totally through a first transmission device and a driving device linked with the first transmission device, an output of a first fly wheel drives a second fly wheel to rotate and amplifies a torque of the second fly wheel to do work. The second fly wheel also feeds back part of an output moment to the first fly wheel through a second transmission device and a first driving device linked with the second transmission device to keep the first fly wheel rotating by an inertia force. A diameter and weight of the second fly wheel are much greater than those of the first fly wheel.

Abstract: The present invention provides a novel power generating device, wherein the rotary inertial force of a fly wheel cooperating with a pneumatic auxiliary power apparatus is employed to maintain that the fly wheel rotates continuously and acceleratingly and outputs power. The part of the output force of the fly wheel is used to drive an air compressor for generating compressed air, to be input into a pneumatic motor of the pneumatic auxiliary power means so that the output power of the pneumatic motor is fed back to the fly wheel in order that the fly wheel maintains the inertial force to rotate continuously. The fly wheel also drives a cam type control apparatus so to control the compressed air that it supplies intermittently to the pneumatic motor for driving the fly wheel. Additionally, the fly wheel is preferably mounted with a weight, and a compensation device for beating the fly wheel in order to increase inertial torque each time when the weight rotates to a predetermined angle.
