Abstract

An Oscillating Water Column (OWC) wave energy device includes a first turbine, and one or more additional turbines, in which the additional turbine(s) can be individually activated in such a manner that both the first turbine and the additional turbine(s) operate at or close to their peak efficiency as mass flow increases. The additional turbine(s) may be positioned in series or parallel with the first turbine and all turbines can then operate at or close to their peak efficiency at a mass flow that would be too high for the first turbine to operate at efficiently.
