On a recent sunny morning in a channel at the Port of Los Angeles, seven blue steel structures that look like small boats are lowered into the ocean one by one. Attached to an unused wharf on a site that once housed oil tanks, they gently bob up and down with the waves to generate renewable power. Nearby, a sea lion peeks from the water and pelicans and sea gulls soar overhead.
In LA port, bobbing blue floats are turning wave power into clean energy
