The diagrams below show the design for a wave-energy machine and its location.
The diagrams illustrate the blueprint for a wave-energy machine and the place where to build it. Overall, it takes several steps to go from water in the sea to electricity and considerations for constructing the machine.
As for the first diagram, water which is located at the bottom is stored. With the movement of the wave, the air will be created and flows through the left slot, operating the first turbine. The remaining air will come back to the starting point. Next, on the top of this machine there are small holes which the outside air can go through and run the second turbine. After this process, some will escape and return to the sky. The activity of two turbines, as a result, will make the generator run and produce electricity.
Turning to the latter diagram, there are two choices to place this machine. First, to reduce installation costs, it can be built in the position that have small waves producing lower output. Or with the other option, setting it up in the location that have large waves to have higher output, but it will cost a huge amount of money to do so.
