The construction company, ICS of North Dakota, lifted the wind turbine rotor assembly, to which the blades attach, 246 feet high into place late yesterday afternoon. After it was lifted it was discovered the blades were not ‘feathered' or turned properly so they could not catch the wind. In the position the blades are in, the wind caught the blades causing them to spin. When this was discovered, the Bremer county sheriff's department was notified and all personnel were evacuated, including two homeowners who were outside of the recommended danger zone.

Last week the old feeder drove through NW Iowa. My route used to offer pleasant scenery most of the way from the feedlot to my destination. I get off of I-29 at Onawa and take the county blacktops to Arnolds Park. For the last 10 years, a growing part of the drive has been through a wind farm. Its like driving through a hellish, whirling machine. Almost everyone agrees that these monstrosities are hideous eyesores. Nobody with any sense of the rural aesthetic wants them anywhere near where they live. ...Now the scenic Iowa roads between Galva and Peterson are studded with the ugly contraptions as far as the eye can see. Perhaps portending worse to come.

Officials from Florida Power and Light Energy have teamed with the manufacturer of wind turbines in an attempt to learn what started a fire that destroyed a turbine Oct. 3 at the Hancock County Wind Farm. ..."We have a large number of these units," said Florida Power and Light spokesman Steve Stengel.

AMES, Iowa -- Wind turbines generate power, but one was rendered powerless when it was knocked over by wind Friday.
