A small amount of electricity can move the wave-making drum to drive the power generator to generate electricity. Multiple floats can be used with a respective transmission mechanism and a respective inertial wheel set to drive one power generator. ## Claims ### Claim 1 A wave-making and power-generating system, comprising: a support frame having a bottom side thereof affixed to the floor or a suitable location of a building and a top side thereof provided with a pivot member;
