Catching Waves and Turning Them Into Electricity
Off the coast of Western Australia, three big buoys floating beneath the ocean’s surface look like giant jellyfish tethered to the seafloor. The steel machines, 36 feet wide, are buffeted by the powerful waves of the Indian Ocean. By harnessing the constant motion of the waves, the buoys generate about 5 percent of the electricity used at a nearby military base on Garden Island.
