Patent ID: 8912678

Claim:
A wave activated power generating device, comprising: a platform; a buoy vertically positioned to rise and fall relative to motion of waves impacting the buoy and the platform, wherein the buoy includes a plurality of heatproof plastic tubes as internal pressure pillars, each of the plastic tubes having four walls and being square shaped in cross section, a hollow interior of each of the plastic tubes being filled with plastic foam particles, an external surface of each foam particle-filled plastic tube being wrapped with soft FRP prepreg material, and the plurality of foamed plastic tubes together being covered by soft FRP prepreg material; a rack and pinion structure operatively connected between the buoy and the platform such that a pinion element of the rack and pinion structure generates rotating torque by moving along the rack element in response to the buoy rising and falling by the wave motion; and a power generator unit operative connected to the rack and pinion structure to generate electricity in response to rotating torque generated by the pinion element.
