The plan, with a possible $3 billion price tag, uses hydrokinetics
-- electrical generation from river currents or ocean waves. The river's flow would spin submerged turbines about two feet in diameter and perhaps made of carbon fiber or some other lightweight source durable enough to withstand being hit by debris swept downriver while not interfering with barge traffic. "It's elegant, it's simple," says Irvin, Free Flow's chief executive and a former investment banker. His company screened some 80,000 river sites across the country. Preliminary permits that Free Flow Power already has from the Federal Energy Regulatory Commission give the startup first right to seek operating licenses for projects at those locations while giving it three years to do environmental and technical studies. Janet Sternberg, a Missouri Department of Conservation policy coordinator, urged FERC months ago to not move too hastily on such projects until more about hydrokinetics is known. "People saw the Mississippi as an opportunity -- here's a big river with a lot of free-flowing water," Sternberg told The Associated Press. "Is this a good place to install this type of energy?" Irvin calls such debate healthy. "We have no objection to the careful scrutiny and scientific question," Irvin said. Stressing that Free Flow's turbines would turn only with the speed of the river, "we're pretty comfortable that what we're proposing is going to be completely benign to fish." Up the river in Quincy, Ill., which hugs the Mississippi's eastern bank, Mayor John Spring thinks installing hydroelectric turbines on three locks and dams could produce 55 megawatts of power
-- enough to supply the city's 16,000 homes. Quincy's plan -- already signed off on by the City Council and with preliminary permits from FERC
-- could cost about $200 million. By the end of this fiscal year, which ends next May, Quincy -- a city with an operations budget of $30 million
-- will have put $1.4 million into the effort. "We'd like to make this part of our state the poster child for hydroelectricity in our country," Spring said. "Normally, you'd never see an entity this size take on such a gigantic project. But I think it's the future, and it's the right thing to do."
