Japanese scientists aim to harness energy from ocean waves

Japanese scientists are aiming to generate electricity by harnessing energy from ocean currents using submerged turbines anchored to the seafloor. The turbines, providing clean and renewable energy, would also protect coasts from erosion. Using just 1% of mainland Japan's seashore, the country can generate about 10 gigawatts of energy, equivalent to 10 nuclear power plants, said a researcher.
