“A Portland-based industrial company completed the construction of a first of its kind renewable wave energy device.”
“The buoy is shaped like an “L” with a long open chamber that sits below the water line and a turbine above the water. As water enters the open chamber it forces air upward, which turns the turbine to generate electricity. When the water recedes, it creates a vacuum and air rushes in to fill it, keeping the turbine spinning and the cycle repeats.”
