Question

State two ways in which the energy of sea-waves can be harnessed.

Answer 1

Two ways in which the energy of sea waves can be harnessed are the following.

1 By setting up floating generators in the sea, which would move up and down with the sea waves. This movement would drive the generators to produce electricity.
2. By letting the sea waves move up and down inside large tubes. As the waves move up, the air in the tubes is compressed. This compressed air can be used to turn the turbines of a generator to produce electricity.
