Abstract: An apparatus for generating electric power comprises an electric generating device mounted on a main frame and including a transmission unit coupled to a pivot rod of a float-mounting frame of a float unit, and a generator coupled to an accelerating unit. The float unit includes two floats connected to the float-mounting frame and riding on a water surface such that the pivot rod is rotatable relative to the main frame in response to water wave front action to generate a bi-directional mechanical rotary power output corresponding to water wave energy. The transmission unit outputs a single directional mechanical rotary power output to the accelerating unit based on the bi-directional mechanical rotary power output. The accelerating unit accelerates a rotational speed of a drive shaft of the generator such that the generator converts rotary power corresponding to the rotational speed of the drive shaft into electric power.

Abstract: A damper power-generating system includes a damper, a driving apparatus, and a generator. The driving apparatus simply consumes energy to do work for generation of electric power. That is, the work is done by utilizing the displacement due to the strong up-and-down vibration within a damper, wherein the displacement due to the up-and-down vibration drives a set of gear racks, which, in turns, drives gears having a one-way driving apparatus, so that rotation can be achieved in one direction, and, further, buffering springs and accelerative gears are used, so that speedy and uniform rotation can be achieved.

Abstract: A propulsion mechanism for a boat includes a boat body; a bar being laterally provided on the boat body; a sliding block being provided on and slidable along the bar; a paddle being pivotally disposed on the sliding block and being submerged in water on which the boat body is floated; a restraining device being coupled to said paddle and being rotated in concert with the paddle; the restraining device limiting a rotatable range of the paddle; and two pulling rings being fixed to the sliding block. The sliding block is drawn to move laterally and reciprocally when the pulling rings are alternatively and reciprocally pulled by a user, so that the paddle moves relative to the water and so that a reactive force is produced to propel the boat body.
