Here in this northwest Missouri farm town, 27 industrial wind turbines have been generating more than electricity -- health concerns, a federal lawsuit and a family feud, for starters. The wind industry, which produces about 1 percent of the nation's energy, has gained considerable purchase in the U.S, growing by 45 percent last year. ...Now come claims that industrial windmills cause what one researcher calls "wind turbine syndrome," a range of symptoms that include headaches, anxiety, sleep problems and dizziness in some people who live close by. "It's like someone swinging a rope over your head," says Gentry County horse breeder Charlie Porter of the several wind turbines within about 2,000 feet of his home near King City.

Two brothers-in-law, a country road in northwest Missouri, a fistfight ...Surely it's happened before, but probably never over wind energy. ...At the heart of the dispute: Just how healthy is the noise from wind turbines? ...In Rock County, Union Township residents studied medical and scientific research for months before drafting their wind ordinance, which says a setback of at least a half-mile from inhabited structures is needed to avoid health problems. Tom Alisankus, chairman of the committee that drafted the ordinance, said committee members found in their research that the state of Wisconsin had no medical or scientific data to back a model ordinance with a 1,000-foot setback. Proposed legislation that would have allowed the state's Public Service Commission to set statewide siting standards failed to reach a vote before the session ended last month. Doctors in other countries, including Canada, England, France, Australia and New Zealand, have written papers about similar illnesses in people who live near wind farms. ..."Does noise bother people differently? Absolutely," said Smith, the area audiologist. "It can have a very debilitating effect." But, he said, before anyone can conclude that the wind turbines are harmful, a major study must be done.

Last year, 400-foot-tall wind turbines were erected near King City, some less than 2,000 feet from Charlie Porter's house on his small acreage. Soon the sounds from the blades swooshing through the air and other noise were driving Porter and his family crazy, he said. "The sound gets in your head like a saw and you can't get rid of it," Porter said. "Some people compare it to a train that never arrived." Porter's complaints upset his brother-in-law, a Gentry County commissioner who helped bring the wind farm and new economy to the area, as well as others. In February, it spilled over into a fistfight between them, then a lawsuit. At the heart of the dispute: Just how healthy is the noise from wind turbines? ...One researcher calls it "wind turbine syndrome," a collection of symptoms that include headaches, anxiety attacks and high blood pressure. Doctors in some other countries have done research on people who live near turbines and say the sounds they emit make them sick. Several researchers suggest that turbines should be set back from homes, schools and hospitals by more than a mile.
