, a simple system is installed beside a wall sea or cliff which includes a chamber, column and turbine and its function is based on the rise and fall of sea water which stems from natural waves. In the first diagram, it can be seen that the beginning step is an entry of water into the chamber so that when water enters the chamber, the air exits from the column. Meanwhile, the pressure of air movement in the tube rotates turbin. In the subsequent stage, dynamic energy that stems from a rotating turbine turns into
