Unexpected Downside of Wind Power - Wired reports on the shutdown of wind power turbines along Altamont Pass in California. Wind power is seen by some as an alternative to burning fossil fuels; yet these turbines are being shut down over environmental and ecological concerns. Some of the concerns about turbines are that they endanger bird migrations, yet others say that they are not a problem for bird migrations. It's not just a question of the ecological footprint, though. The entire environmental impact has to be assessed for any project. Hydroelectricity is not without its effect on ecosystems, either (Scroll down to "Ecosystems and Large Dams", about 40% of the way down).
If even green or renewable energy sources cannot be accessed without a significant adverse environmental impact, how can we meet our energy needs? Reducing consumption is only approaching the problem from one side. How do you properly gauge the environmental impact of a project and when is it okay to give it the green light? Or are we being oversensitive and should we let natural selection handle the birds that can't adapt?

45,000 pounds + four 130 foot rotors + up to 200 mph Jet Stream winds = Energy Problem Solved Like the monster mother of all kites, a company called Sky Windpower (whichsportsanexcellentwebsiteabouthighaltitudewindpower) has been founded by an Australian engineer with three others to attempt to harness the near limitless windpower of the jet stream with a machine they call an FEG (Flying Electric Generator). They're currently seeking $4 million to build a 200 kilowatt prototype but still need to get FAA clearance to fly it. The production models would generate 20 megawatts each and would be flown in farms of up to 600 turbines to generate enough power to light up two cities the size of Chicago. Power and control of the huge machines would be handled by a three inch thick tether connected to a winch on a ground station.
Man, I love Popular Science!

It's official: wind power is now cheaper than electricity from Coal, Stanford Researchers report in a study published in the Journal Science. Quiz for Metafilter science wonks: how much of current US energy consumption could be supplied by spending 200 billion dollars on wind turbines?
Meanwhile...Powered by 6800 lithium-ion batteries, the Tzero "from zero to 100 and through the quarter mile, will run with, or beat, the $281,000 Lamborghini Murci
