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 following diagram shows the model of wave-energy machine along with the second diagram showing the location options for installing wave-energy machines. The first diagram depicts the pictorial representation of wave-energy machine which generates electricity using tidal wave energy. The machine has mainly two chambers, the underneath chamber has inlet point for water waves and the upper part contains the set of turbines which generates the electricity using the generator. As shown in the figure, when the water levels rises in the below chamber, it generates a gust of air wind into the above part of machine. Due to the airflow generated into the second chamber, the turbines starts to revolve around the axis, which gradually rotates the axle of generator attached to them. The amount of water levels in beneath segment is directly proportional to blow of air, which in turn spins the turbines. The second diagram represent the possible location options into the reservoirs, to install the wave-energy machines. It clearly shows that the to get large waves-high output, the machine must be installed away from the shore, which incurres the high cost. It also shows that to get lower the cost the machine should be installed near the shoreline.
