A pilot project in New York's East River is evaluating the use of underwater turbines to generate electricity. If the project bears fruit, the technology could have widespread applications. The effort, formally called New York's Roosevelt Island Tidal Energy Project, is being conducted by Verdant Power and the New York State Research & Development Authority.

"Compared to other sources of distributed generation, this technology is not episodic." -- Trey Taylor, Verdant Power, president
