Abstract: In early studies conducted at New York University (NYU) at the request of New York Power Authority (NYPA) a number of conclusions were reached regarding the resource and the types of kinetic hydro energy conversion systems (KHECS) which could be utilized to exploit it. A technology assessment yielded a number of types of devices which could be practical, while criteria including efficiency, simplicity, cost-effectiveness, and near-term commercialization indicated an advantage to axial-flow propeller machines in both tidal flows and rivers. Rotor blades designed according to H. Glauert theory were tested and produced the necessary high efficiency. Because units must operate reliably underwater for extended periods, variable blade pitch or variable speed drive mechanisms add a degree of complexity which should be avoided if possible. These factors have been accommodated by careful rotor design and selection of drive and generating components. The current study involves the design, fabrication, and testing of a grid-connected full-scale prototype in New York's East River and the determination of the national resource.
