law from taking effect in this year's election as part of a wider challenge to its constitutionality.

The judge's decision Tuesday could be appealed to the state Supreme Court, but it could easily be the final word on the law before the Nov. 6 election.

The constitutionality of the law was not a question before the judge.

Other states face similar debates over voting.

The U.S. Supreme Court upheld Indiana's voter ID law in 2008, and Georgia's top court upheld that state's voter ID law. But a federal panel struck down Texas' voter ID law, and the state court in Wisconsin has blocked its voter ID laws for now. The Justice Department cleared New Hampshire's voter ID law earlier this year.

Such cross-flows act to negatively impact on blade performance, in particular by contributing to airflow detachment from the surface of the blade, thereby affecting blade lift.
It is known to provide a barrier or stall fence which extends across the surface of a wind turbine blade, transverse to the longitudinal axis, to prevent the formation of such cross-flows. An example of such a wind turbine blade can be seen in U.S. Pat. No. 7,585,157.
While this system prevents the cross-flows from propagating along the blade length by providing a barrier between adjacent sections of the blade, during rotation of the wind turbine blades the centrifugal
