1. A wave activated power generating device, comprising:
a support frame;
a buoy vertically positioned to rise and fall relative to motion of waves impacting the buoy and the support frame, the buoy being formed with a hollow interior space;
a rack and pinion structure operatively connected between the buoy and the support frame such that a pinion element of the rack and pinion structure generates rotating torque by moving along a rack element in response to the buoy rising and falling by the wave motion;
a power generator unit operatively connected to the rack and pinion structure to generate electricity in response to rotating torque generated by the pinion element, wherein
the rack element is fixedly connected to at least one vertical surface inside the hollow interior space of the buoy,
the pinion element is fixedly mounted on the support frame to extend into the hollow interior space of the buoy and operatively positioned to movably interconnect with the rack element as the buoy rises and falls; and
a plurality of guide rollers fixedly attached to an exterior surface of the buoy and operatively positioned to movably interconnect with the support frame and guide the rising and falling of the buoy.
