Tidal irrigation and electrical system (TIES)
A tidal irrigation and electrical system used to harness the power of the ocean tide to generate electricity, create sustainable aquaculture, act as a CO2 sink, and generate hydrocarbons. An artificial atoll is created on the continental shelf to define a lagoon completely isolated from the surrounding ocean. As the tides rise and fall, the natural tidal action draws nutrient-rich, cold seawater into the lagoon to stimulate the growth of biolife. As the ocean tide falls, the natural tidal action draws the lagoon water out of the lagoon and through a biofilter to remove the biolife prior to discharge of the water back to the ocean.
