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 pictures illustrate of design of wave-energy machine and where it is located.
Firstly, a waves movement coming to the machine and fills up inside it. If water levels meets to the limit, its rises to the top of chamber lower side and produced an air. The air flows into upper side of chamber and spins the lower turbine. Then, on upper side of chamber, there is another turbine which is moved by the air coming from above and resulted energy to electricity generator.
Furthermore, the location of wave-energy machine is determined by waves power. If further the machine located from the coastline, then more power produced as well as higher cost needed to construct. Otherwise, if nearer the machine located from the coastline, that will make cheaper to build even though electricity power would smaller to produce.
