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.

You should write at least 150 words.

The diagram illustrates the process of constructing of a wave-energy and what is ideal location of this device.

According to the details, the first image shows about the construction and function of the wave-energy. The device consists of two main chambers, a turbine and a electricity. The turbin is placed inside the top chambers that connected to a generator. The level of water that is obtained in the below chamber rises as the waves move towards to it, which imprints the pressure to the air flows on the top chambers. After that, the air blows inside the top chamber make the turbin spin and then it escapes into the asmotphere. The second major stage occurs during the ebb of the tide and involves a reverse flow of the air that blows into the top chamber. As a result of the turbine's spinning, electricity is produced by the generator.

In the second image, there are two potential locations for the wave-energy machines. The first site is in the deeper water in which larges waves are available, but its installation is higher costs. However, the second site is cheaper for construction as it is located in the seashore where the waves are regularly lower and smaller.
