Generating Electricity From Ocean Waves

Generating Electricity From Ocean Waves: We can convert the energy of ocean waves into electricity at places where there are strong waves.

Figure shows schematically one setup for generating electricity from waves. A large air-filled object, called a surface follower, floats in the sea and moves up and down with the waves. It is linked to a shaft at the bottom of the sea in such a way that its up-and-down motion is converted into the rotational motion of the shaft. The rotation of the shaft is used to turn the shaft of an electric generator.
