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

Sea-waves energy can be harnessed by the following ways:

a) By setting up floating generators in the sea. They would move up and down with the sea-waves and their movement would drive the generators to generate electricity.

b) By letting the sea-waves move up and down inside large tubes so that when the waves move up, the air in the tubes is compressed and this compressed air can then be used to turn a turbine of a generator to produce electricity.
