The image contains two diagrams related to wave-energy machines. The first diagram shows a wave-energy machine's components and flow direction. It features an electricity generator at the top, connected to a turbine, with chambers below and air flow depicted through arrows. The bottom section shows water levels and the wave direction indicated with an arrow. The second diagram presents wave-energy machine location options based on wave size and installation costs. It depicts four quadrants with varying levels of wave size and installation costs. One quadrant shows large waves with high output and high installation costs, while the opposite shows small waves with low output and low installation costs, with wave-energy machines placed in between the two ends of the spectrum.

The diagrams depict how a wave-energy machine runs and where it is located. Overall, the machine utilizes wave energy to generate electricity and the location of each machine could create a difference in output level and installation cost.
In terms of the first diagram, when a wave travels into the lower chamber, the water level inside rises up, leading to an air flow entering the lower chamber and moving the turbine. At the same time, an air flow is sucked into the upper chamber from outside. This process turns the turbine and generates electricity.
Regarding the location of a wave-machine, it can be installed near the coast or far in the sea. In the coast, a machine generating electricity by small waves is correlated with low output as well as low installation cost. Conversely, a generator located far from the mainland can produce electricity more productively, but it also costs higher expense. In addition, the machine installed in the coast is smaller than the one in the sea.
