What is the Salter's duck Explain briefly?

Answer 1

Salter's Duck, also called the Edinburgh Duck, is a floating device designed to capture the energy of ocean waves. As the Duck bobs up and down in the waves, a pendulum inside swings, generating electricity.

The idea was developed during the oil crisis of the 1970s. Now that interest in renewable energy is again urgent, it is being worked on again. See the animation at the link below.
