River Turbines On Floating Dock Could Electrify New York City

A New Jersey Institute of Technology professor and a student have developed a proposed design for floating docks that capture energy from river flows plus provide recreational space.

Charles Choi for LiveScience and MSNBC.com reports:

"Each dock could generate power off the city's river currents. Three vertical turbines fastened out of sight to the underside of each station would harness the 4 mph currents, with each module generating up to 24 kilowatts of constant energy from the Hudson and East Rivers.
These stations would plug into the conventional piers of the city, extending them into the rivers. They could alleviate the need for conventional power to light the city streets, with each module supporting 350 LED streetlamps.

These docks could eventually get extended further up the rivers to both generate power and increase recreational green space and tidal pools for wildlife, said researchers at the New Jersey Institute of Technology and at GRO Architects in New York. They currently have a provisional patent on the idea." See full article.
