[Problem] To provide a feedback power generation system capable of generating power without sunlight, even in a no-wind state, and by a totally different method independent of natural forces (natural energy) such as, for example, water flow. [Solution] A feedback power generation system (10) of the present invention rotates propulsion blades (15) by electric motors (12), converts the generated propulsion force to a larger force proportional to the length of an arm (14) by using "the principle of leverage", and sufficiently drives a power generator (11). That is, the total input power to the electric motors (12) is converted in power by applying "the principle of leverage", thereby enabling the operation of the power generator (11) to be maintained, and a relationship of "the output of the power generator (11)" » "the total input power to the electric motors (12)" is satisfied. In addition, part of the output power generated by the power generator (11) is fed back to and appropriated for the input power to the electric motors (12) to drive the electric motors (12), thereby obtaining a relationship of "the output of the power generator (11)" - "the inputs to all electric motors (12)" = "the effective output of the power generator (11)".

||14434960||Yanming Qu||Yanming Qu|
The present invention is related to a method and system for wave power generation. When a floating body rises with the wave, a hydraulic cylinder is being pulled to drive a hydraulic motor; the hydraulic motor will in turn drive the generation of power. When a stroke action of the hydraulic cylinder is completed, signals will be transmitted to a drum to release the rope, at which time the hydraulic cylinder will be reset. When the reset is completed, the distance between the floating body and the anchor base increases, the hydraulic cylinder is pulled again, thus repeating the above process. When the floating body drops along with the wave, the hydraulic cylinder is reset at first and then the drum retracts the rope. This system can automatically reset the hydraulic cylinder and do work multiple times during the process of one rising wave.
