Giants of the Amazon

Last night's Nature program featured "the giant of the Amazon," the Brazil nut tree, which can live for hundreds of years and reach a height of 160 feet. That's less than half the height of most modern wind turbine assemblies. And because even those giant wind turbines don't appear to have any positive effect on electricity use, manufacturers are making them even bigger. GE has recently come out with its "2x" series, ranging from 367 to 548 feet high, the blades chopping through 1.4 to 1.7 acres of air. These are the models planned for Gore Mountain in the Adirondacks and which environmentalists like Bill McKibben think would be a fine addition to the park's wilderness.
