Submerged Turbines Could Replace 10 Nuclear Reactors In Japan. Okinawa Institute of Science and Technology (OIST) researchers have developed turbines to convert the power of ocean waves into clean, renewable energy. Professor Shintake and the Quantum Wave Microscopy Unit at OIST began by starting a project titled “Sea Horse,” aiming to harness energy from the Kuroshio ocean current that flows from the eastern coast of Taiwan and around the southern parts of Japan. That project used submerged turbines anchored to the sea floor through mooring cables that convert the kinetic energy of sustained natural currents in the Kuroshio into usable electricity, which is then delivered by cables to the land. The initial phase of the project was successful, and the Unit is now searching for industry partners to continue into the next phase. But the OIST researchers also desired an ocean energy source that was cheaper and easier to maintain.
