I can't find it right now, but the last time someone asked this question I found a calculator on the energy that you can get out of the wind at a given speed and for 55mph I think you could get about 200 watts out of a turbine that was about 2 feet across, so how do they get around 100 watts out of a little 6" turbine? they are going over 85mph! just like it's going to take signifagently more energy to go 85mph, you can also get more energy out of the wind when you are going that speed! just like you can get 3/4 more out of a 12mph wind then you can out of 11mph wind.
So a turbine like that might be able to run your LED running lights, but not much else unless you are going above the speed limit.
