Question

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

Answer 1

Answer:

we can use it to produce electricity

Answer 2

Answer:

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

1. By setting up floating generators in the sea which would move up and down with the seawaves and their movement would drive the generators to produce electricity.

2. 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.
