How Fishy Technology Could Power the Future
Editor's Note: Each Wednesday LiveScience examines the viability of emerging energy technologies - the power of the future.
Think like a fish not like a bird, say researchers trying to harvest energy from water currents. Their new fish-inspired power generator can work in slow-moving currents where traditional turbines are less effective.
Tidal streams and moving rivers in the United States could generate 140 billion kilowatt-hours per year, or about 3.5 percent of the nation's electricity demand, according to the Electric Power Research Institute (EPRI).
