Abstract:
1. A system for converting water wave energy into the production of compressed air, the system comprising a manmade blowhole constructed inside the protection of a natural geological formation, wherein the manmade blowhole is a long tapering shaft in which large waves can enter at an opening in said natural geological formation, said waves race up said shaft as a water piston, said large waves rise and fall in the said tapered shaft with the cycle of each consecutive wave, the air trapped in front of said water piston is compressed as said water piston moves deeper into said tapering shaft, said compressed air is allowed to vent off through an emergency relief valve during emergency shutdown situations or storms, said emergency relief valve allows said compressed air to vent out through the natural geological formation when said emergencies occur, under normal operation said compressed air will travel through an emergency shutdown valve that will only close during said emergency shutdown situations or storms, and then will pass through a one-way check valve which will prevent said compressed air from being drawn back into said blowhole shaft as said wave subsides, when said wave subsides a resulting vacuum forces a fresh air intake valve to open as the receding wave moves back out of said blowhole and fresh air rushes through said air intake valve to fill said blowhole shaft with outside air in preparation for the next incoming wave, said compressed air that is generated passes through said check valve and enter a compressed air header piping which feeds one of air-driven turbines that run electrical generators, and excess compressed air is collected in air dehydration vessels and stored in back up compressed air storage vessels that are connected to high pressure pipelines for use inland.
