Before revision: It was developed for use in Oscillating Water Column wave power plants, in which a rising and falling water surface moving in an air compression chamber produces an oscillating air current.
After revision: Unlike air, water is essentially incompressible...so what follows is horse shit and fairy dust:It was developed for use in Oscillating Water Column wave power plants, in which a rising and falling water surface moving in an air compression chamber produces an oscillating air current.
