Writing Feedback / [IELTS TASK 1] The diagram shows how a wave-energy machine is designed and where it can be located [5]
Summarise the information by selecting and reporting the main features and making comparisons where relevant.
You should write at least 150 words.
The given diagram shows how a wave-energy machine is designed and where it can be located. Overall, the wave-energy machine is used to generate electricity and the location options are different due to its cost and output.
As can be seen from the diagram, this machine includes 2 main chambers. The wave first travels into the lower chamber of the machine causing the water level to rise and then create an airflow. This airflow goes to the upper chamber and makes the turbine begin spinning. At the same time, another turbine is rotated because the air from the outside flows into the chamber and puts atmospheric pressure on the water. This process generates electricity for people on the land.
The location of the machine depends on the cost and output. The nearer machine to the land is installed in an area having a small output which also requires a lower cost to install, while a machine located in a high output place needs a high installation cost
