The diagram shows two ways of using the energy from ocean waves to generate electricity.
Overall, electricity is produced by converting wave movement into mechanical energy, which is then used to power a generator. While the first method uses water pressure to drive a turbine, the second relies on airflow created by waves.
In the first method, waves enter a chamber through an intake pipe, causing a float to rise and fall. This movement activates a piston, which pumps water into a storage tank. The stored water is then released through an outlet pipe, where it flows through a turbine connected to a generator. As a result, electrical power is produced.
In the second method, incoming waves cause air inside a chamber to move upwards and downwards. As the air flows in and out, it passes through a turbine installed at the top of the chamber. This turbine rotates in both directions and drives a generator, thereby producing electricity.
