The diagrams below show an arrangement that is used to produce electricity from wave power.

The diagrams below show an arrangement that is used to produce electricity from wave power. GLOwB

The two diagrams show how to generate electricity utilising the power of waves and a specially built man-made structure. The first diagram depicts how an incoming wave fills a big chamber, forcing the air inside to rise up the column and through the turbine. The turbine is rotated by the air pressure, which provides an electric current. As can be seen in the second diagram, the process does not end there as the structure can continue to generate power as the sea fades. As the water flows away from the structure, it pulls air down the column and through the turbine in the same direction as the earlier upward flow of air. As the turbine continues to spin, more electricity is generated. Overall, The construction, which consists of a wave chamber and a tall column with a turbine, is built on a steeply sloping coastal cliff or sea wall and is subject to the movement of the ocean waves.
