Old mine could supply new power

Some look at an abandoned, centuries-old iron mine in New York's Adirondacks and see a relic. An ambitious group of engineers sees the shafts in Mineville as a new way to provide a steady flow of electricity in a growing market for renewable energy.They are pitching a plan to circulate some of the millions of gallons of groundwater that have flooded the mine shafts over the years to power an array of 100 hydroelectric turbines a half-mile underground.
