Wave Energy Turbine
The Hanna Wave Energy Turbine was granted U.S. patent 8,358,026. A description of the technology is at www.wetgen.com. At present (2016) the technology is at TRL 2-3. The turbine operates by the Oscillating Water Column (OWC) principle. It is a special air turbine that is designed to rotate in one direction at all times during alternating or bi-directional air flows commonly found in OWC wave energy systems. The turbine is both an Impulse type turbine and a Reaction type turbine.
