You should spend about 20 minutes on this task. 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 diagrams below show the design for a wave-energy machine and its location. w95m
The diagrams illustrate the interior design of a wave-energy machine along with the possible locations to install the machine. The wave first travels into the lower chamber of the machine, which causes the water level to rise and creates an upward air flow that turns the turbine above the chamber. At the same time, the other turbine is caused to spin due to the atmospheric air from outside flowing into the upper chamber. This process generates energy using the speed of the turbines caused by the different air flows. While the mechanism of the machine is comparable from machine to machine, the location of each machine correlates with the amount of energy generated as well as the costs involved. The nearer the machine is to mainland, the lower the output, with the best energy generators being far away from land. Coincidentally, machines with lower output also requires lower costs to install. Overall, the wave-energy machine utilises wave energy to generate electricity. The location of installation, however, creates a difference in administrative costs and output level.
