An ocean wave generator includes a buoy for floating on the surface of the ocean. A generator is mounted to the buoy. A pulley is mounted on the generator for turning the generator. An anchor cable has a first end wrapped around the pulley and an anchored second end. Upward movement of the buoy and generator due to a wave causes the cable to unwind from the pulley, which turns the generator. A spring connected to the pulley rewinds the anchor cable when the buoy and generator drop into the trough of a wave.

What is claimed is: 1. An ocean wave power generating apparatus, comprising: a buoy floating on a surface of an ocean; an electrical generator mounted to the buoy for upward and downward movement with the buoy in response to waves; a uni-directional pulley mounted on the generator for rotating the generator in a first direction when the pulley rotates in the first direction and for allowing the generator to continue rotating in the first direction when the pulley rotates in a second direction; a spring in engagement with the pulley for urging the pulley to rotate in the second direction; an anchor line having an upper end wrapped around the pulley and a lower end anchored, so that upward wave movement of the buoy pulls on the anchor line to cause the pulley to rotate in the first direction, and downward wave movement of the buoy causes the spring to rotate the pulley in the second direction to rewind the anchor line; a submerged support frame; at least one mooring line extending from the support frame to a sea floor for retaining the support frame below sea level; and wherein the lower end of the anchor line is secured to the support frame. 2. The apparatus according to claim 1, further comprising an ocean current generator mounted to the support frame for generating electrical power in response to ocean currents. 3. The apparatus according to claim 1 wherein the generator has a housing that is filled with an inert gas. 4. An ocean wave power generating apparatus, comprising: a buoy floating on a surface of an ocean; two stators mounted to the buoy; a rotor rotatably mounted in each of the stators for generating electricity when rotated; a single shaft coupled to both rotors for rotating the rotors in unison; a uni-directional pulley mounted to the shaft between the rotors for rotating the rotors in a first direction when the pulley rotates in the first direction and for allowing the rotors to continue rotating in the first direction when the pulley rotates in a second direction; a spring in engagement with the pulley for urging the pulley to rotate in the second direction; an anchor line having an upper end wrapped around the pulley and a lower end anchored, so that upward wave movement of the buoy pulls on the anchor line to unwind the anchor line and cause the pulley to rotate in the first direction, and downward wave movement of the buoy causes the spring to rotate the pulley in the second direction to rewind the anchor line while the rotors continue rotating in the first direction; a submerged support frame; at least one mooring line extending from the support frame to a sea floor for retaining the support frame below sea level; and wherein the lower end of the anchor line is secured to the support frame. 5. The apparatus according to claim 4, further comprising an ocean current generator mounted to the support frame for generating electrical power in response to ocean currents. 6. The apparatus according to claim 4 wherein the stators and rotors are located within an inert gas atmosphere. 7. An ocean wave power generating apparatus, comprising: a plurality of buoys floating on a surface of an ocean; an electrical generator mounted to each of the buoys; a uni-directional pulley mounted to each of the generators for rotating the generators in a first direction when the pulley rotates in the first direction and for allowing the generators to continue rotating in the first direction when the pulley rotates in a second direction; a spring in engagement with each of the pulleys for urging the pulleys to rotate in the second direction; a submerged support frame; a plurality of mooring lines extending from the support frame to a sea floor for retaining the support frame below sea level; and an anchor line for each of the buoys, each of the anchor lines having an upper end wrapped around one of the pulley and a lower end secured to the support frame, so that upward wave movement of the buoys pulls on the anchor lines to cause the pulleys to rotate in the first and downward wave movement of the buoys releases tension in the anchor lines to cause the springs to rotate the pulleys in the second direction to rewind the anchor lines. 8. The apparatus according to claim 7, further comprising a plurality of ocean current generators mounted to the support frame for generating electrical power in response to ocean currents. 9. The apparatus according to claim 7 wherein each of the generator is located within a housing that is filled with an inert gas.
