The diagrams below show the design for a wave-energy machine and its location. Summarise the information by selecting and reporting the main features and make comparisons where relevant.

The diagrams below show the design for a wave-energy machine and its location. Le08
The diagrams show how a wave-energy machine works and locations where such a machine may be installed and the advantages and disadvantages of choosing the different locations. In the first diagram, we can see that when the wave-energy machine is placed in the water the opening at the bottom of the machine needs to be in the direction from which the wave is coming. The lower half of the machine needs to be submerged in water. There is an opening at the left top corner of the machine through which air enters, making the turbines within the machine rotate. Once the water enters the lower chamber from the opening at the bottom, the water level rises and pushes the air out of the chambers making the turbines rotate in the opposite direction. This air then escapes the machine through the opening in the top right hand corner of the machine. This process helps to generate electricity. In the second diagram we can see that when the machine is placed in a location where the waves are large, it helps to yield high output of electricity but the installation costs of this set up is also higher. On the other hand when the machine is placed where the waves are smaller, the installation costs are low but so is the output of electricity
