The mix diagrams illustrate the brief design, mechanism and general location of a wave-energy machine.
As can be observed in the first picture, the system includes several different parts: an electricity generator, two turbines, and chambers with a series of holes that serve as ventilation conduits. It operates when waves initially enter the lower chamber through a large opening in the bottom part, which affects the internal water levels compared to those outside. When the air flow generated by the movement of water inside the bottom part goes through smaller ducts on the second floor, it activates the turbine blades, which are the primary drivers of the electricity generator. The air flow finally goes out through the upper sub-chamber pathway located on the top of the whole machine.
In terms of the location, there are two common options for positioning the wave-energy machines. Some of them are often installed in deeper areas of the seabed, where they receive larger waves and produce higher output. As a result, their installation costs are significantly higher. In contrast, the other machines are installed closer to the shore, which means they receive smaller waves and generate lower output. However, the total costs are lower compared to those located offshore and in deeper water.
Overall, the combined diagrams indicate a complex operating mechanism along with the construction expenditure corresponding to the specific locations where these electricity generators are installed.
