How does an OWC work?

        }Wave motion induces pressure changes beneath the column.
}Pressure changes in turn cause the water level in the camber to oscillate.
} Oscillating water level causes airflow in the chamber.

Wells Turbine


    Wave movement creates changes in volume for the air to occupy.  This causes pressure differences that the air flow is directed into the Wells turbine chamber.  The Wells turbine consists of aerofoils whos symmetry directs the air in the same direction creating unidirectional rotation for the oscillating airflow.  This allows for the tubine to power the generator at all times regardless of the direction of airflow.
