The diagrams show a structure that is used to generate electricity from wave power.
The process of electric generation from the sea wave is shown in the graphs which the "A" graph inform the process when the waves come to the chamber and "B" graph present when the wave leaves the chamber. Overall, it can be seen that the air is forced by the direction of wave and rotates the turbine to produce electricity.
First of all, this machine is placed beside cliff or sea wall, which consists of the chamber used for catching the sea wave, the turbine for generating electricity, and the column for air ventilation.
The process started when the wave goes to the chamber. Then, the air is gone by the wave to the top of the column and the air rotates the turbine in the clockwise direction. The power is produced as the result of the generating-electricity process by the turbine. Furthermore, when the wave leaves the chamber, the turbine is rotated with the same direction by the air coming from upper column to the chamber, producing electricity that can power up a lamp.
