Wayne Krouse has a seductive idea: dam-free hydropower. In a year, his start-up, Hydro Green Energy of Houston, plans to have a pair of turbines pumping electricity from under the Mississippi River at Hastings, Minn.--a town willing to give a new idea a try. "Everybody likes a science experiment, and this is just a big science experiment," says Tom Montgomery, Hastings' public-works director. The barge-mounted turbines will be unconventional, but Krouse's design yields twice the energy of earlier versions--and doesn't require new dams, which take years to license...
...fast, Aquaman. Regulators and environmentalists want a long look at dam-free hydro. Krouse knows that what he calls the "sushi problem"--turbines slashing passing fish--will be a big concern. He says fish whacks will be minimal...
...Hastings project underscores the potential for inland dam-free hydropower--30,000 MW, roughly 10% of existing U.S. coal-burner capacity, according to U.S. Department of Energy estimates. The green lobby, which fights dams, is not yet sure what to make of dam-free hydro, but it is wary. True, you can pull a turbine out of the water if things go badly--but "you don't just put one turbine in the water," says Robbin Marks of American Rivers. "To generate a fair amount of electricity, you have to put in hundreds. We really don't know what...
...overcome, would have seen Congress finally pass the Civil Rights Act of 1964. Friends and strangers alike would have assured them that their daughters had not died in vain - that they had awakened the conscience of a nation and helped liberate a people; that the bomb had burst a dam to let justice roll down like water and righteousness like a mighty stream. And yet would even that knowledge be enough to console your grief, to keep you from madness and eternal rage - unless you also knew that your child had gone on to a better place...
