production of wave energy

production of wave energy yXpEE
The pictures illustrates the arrangement of a wave-energy machine and its geographical location. The diagram explains the working mechanism of a wave-energy machine to generate electricity as the final output. The machine has two chambers in total, one for water inlet and the other for the turbine to rotate. The lower chamber has one inlet channel for a wave to pass through. On the other hand the upper chamber has two channels for the air to pass through. In between the two chambers there is a partition with two channels for the air to flow. The upper chamber comprises of turbines connected to a generator. Whenever the air passes through the upper chamber or the lower chamber creates an air pressure when there is a wave in the direction of land, the turbines rotate and the generator generates electricity. If the wave-energy machines are located near the land the installation costs are low but produce less electricity. Contradictorily if the devices are located towards the sea farther away from land they are expensive to set up but produce large amount of electricity.
