The diagrams illustrate how electricity can be produced from the power of the sea. The process involves a structure which is built onto the side of a cliff or sea wall. This structure consists of a large chamber. One end is open to the sea and the other leads into a closed vertical column. A turbine is positioned inside this column and this is used to generate the electricity in two phases. The first diagram indicates that when a wave enters the mouth of the chamber, air is forced up the column. This movement of air turns the turbine, thereby producing electricity. The second diagram shows that when the wave retreats, air is sucked out of the column and chamber. This movement similarly turns the turbine in the same direction and this generates electricity. Overall, we can see that this process creates electricity from waves as they both advance and retreat.
