Catestrophic tornado: 1 turbine blade lands on a daycare, location of other 2 blades unknown

The blades of a wind turbine located at a vo-tech center in Oklahoma were thrown by a tornado that hit the area. One of the blades smashed into a daycare center a quarter-mile away. ABC News reports that the whereabouts of the other two blades are still unknown. In addition to this single turbine, the Canadian Hills wind energy facility is eight miles away. Another project is proposed in an area just 3 miles away. Duration: 4 minutes 17 seconds

Looking for answers in turbine collapse

As a damaged wind turbine lays on the ground behind Western Reserve High School where it fell from its tower Sunday afternoon, the district's two other electricity-generating units sit idle while officials with the company that built them try to determine why this one collapsed. The district installed the turbines in 2009, using state funds to cover most of the costs. But the Scottish firm Proven Energy issued a worldwide recall last year to correct a bearing problem discovered in a turbine being used overseas. Duration: 2 minutes

Wind catches blades, crashes turbine

Turbine components weighing 50-tons fell 246 feet to the frozen ground on Saturday (Feb 20, 2009) when the blades of a turbine under construction east of Waverly caught wind and started rotating at a speed reaching 60 rpm. The hub housing the generating components of the Cannon II turbine and the structure's three 177-foot blades collapsed after spinning for hours at the mercy of the wind, says Waverly Light and Power General Manager Diane Johnson. A gust caught the blades prematurely on Friday because, prior to the installation, they were not turned in a way that would have prevented them from catching wind until construction was complete, according to a press release issued by the municipal utility. "It could have spun for days," Johnson says. On Monday, as the mangled blades lay at the base of the tower, construction crews worked to dismantle the structure's top and middle sections to reinforce the turbine. Crew and neighbors were evacuated overnight until the structure collapsed under its own weight. Duration: 10 minutes
