Writing Task 1: A structure that is used to generate electricity from wave power

The diagrams show a structure that is used to generate electricity from wave power.
The diagrams illustrates how wave power can produce electricity by installing a simple structure nearby cliff or sea wall. Overall, the electricity can be turning on, if the current wave moves into the landward.

To create a structure, needs a specific shape of column, a turbine, and a lamp which should be installed in the edge of cliff. The column contains of two steels that connect with each other, and these steels create a chamber formation in other side whose shape similar to current wave. In addition, the two steels are also used to hold a turbine which has same direction, and connect directly to the lamp.

First of all, the function of the column is as a recharge area when the wave appears to move onward to the sea wall. Then, a strong wave is able to convert a large air which can conduct the turbine to produce a power as the main electricity for the lamp. However, if the wave is moving seaward again, the turbine can generate a small amount of electricity. (172)
