The diagram illustrates a device that is use to produce electricity from the rise and fall of sea water.
The structure is built on cliff or sea wall and consist of 3 main parts. The first part is a vertical column which allows air to flows in and out. It is also connected to a chamber that has one end open to the sea. Inside the column is a turbine that will spin only in one direction when there are air circulates through it.
When the sea level rises, the water puts pressure into the air and pushes it out of the column. This movement of the air makes the turbine spin and thus creates electricity.
If the wave retreats, the motion principle of the device is almost the same. As the sea level decrease the air is sucked back into to chamber through the column. Consequently, this creates force to make the turbine spins and give out electricity.
