Researchers Analyze Role Of Shear In Turbine Passage
RICHLAND, Wash. - Although turbines have generated power at hydroelectric damsfor more than 100 years, not much is known about how water flowing through theturbines may harm fish. Researchers at the Department of Energy's Pacific Northwest NationalLaboratory are working to provide some answers. Th......ally recharged by a coil inside thefish that draws power from an electromagnetic field that permeates the fishtank.
