Traffic was snarled Monday afternoon on U.S. 59 in northeast Houston after a piece of a wind turbine fell off a big rig during a crash.
Local resident David Cofell found this piece from a wind turbine blade in his field after it flew off from a nearby turbine. The provincial Ministry of Energy will launch an investigation into reports that an 18-inch chunk of a wind turbine blade came loose and flew some 400 feet before landing in a field in the former Howard Twp.
An 18-inch piece of the serrated edge of a wind turbine blade broke off and was thrown at least 400 feet from the turbine sited in Ontario, Canada. The saw-toothed edges are meant to reduce noise from the turbines and improve the efficiency of the machine. More information can be found here.
The Japanese government announced plans to hold periodic safety inspections of wind turbines in response to several recent accidents, as the country's operators were urged to fit lightning protection systems.
An investigation into a damaged wind turbine blade at the Eastern Kings Wind Farm is still underway, says head of external communications for the company who makes the turbines.
The 100 metre high turbine was inaccessible to firemen who could do little more than ensure that surrounding area did not also catch fire. ...Due to the intense heat, two of the huge windmill blades fell off and the stiff wind threw sparks over a long trajectory.
A homeowner near the north-east village of New Deer was left bewildered yesterday after a wind turbine has crashed to the ground through the night. ...David Richards, who lives in view of the toppled turbine, described last night how he had first noticed that it had fallen over in the early morning of yesterday.
A row has erupted between the developer of Boro FC’s wind turbine and Durham Tees Valley Airport over alleged passenger safety issues. The 136 metre turbine was given the green light in 2008 but the approval came with a condition that, before operation, a scheme to alleviate the impact of the turbine on the airport radar must be submitted and approved by the local authority.
A 44-meter wind turbine collapsed following a lightning striking one of the 26 turbines at the Little Cheyne Court wind facility.
This wind turbine blade has been bent back like a spoon - despite being a colossal 44 metres long and weighing 275 tonnes.
The Defense Department has held that towering turbines in Somerset, across the Chesapeake Bay from the Patuxent River Naval Air Station would interfere with military radar-testing. ...The same day, Fleury, the chairwoman of the Somerset County Planning and Zoning Commission, quit abruptly, citing dismay over the panel majority’s passage of provisions she warned posed potential “health hazards connected with turbines, especially those greater than 400 feet.”
Although turbine maker GE confirmed the event, it would not provide many specifics. However, the company maintains that the incident has nothing to do with a series of previous failures with its 48.7-meter blades. ...As GE and BP investigate the failed blade at Mehoopany, the wind farm remains the subject of competing lawsuits stemming from construction of the $250 million project.
A blade of a wind turbine separated and crashed to the ground on the South Mountain in western Wyoming County on Sunday. ...The 88-turbine park opened in January 2013.
“Del. John Bohanan and I were confident that once the project was fully reviewed by the Department of Defense, after consultation with various service branches that utilize Pax River, that this would be the outcome,” Hoyer said. “It was the right decision, and I applaud the Department of Defense leadership for recognizing the threat this project poses to a critical national security asset.”
The letter, signed by Deputy Defense Secretary Robert O. Work, does not elaborate. But Hoyer said Pentagon officials had concluded the turbines pose "a significant threat" to the "world-class stealth radar system" used at the base.
This letter, signed by Deputy Defense Secretary Robert O. Work, concludes that the turbines proposed for Somerset County in Maryland would "significantly impair or degrade the capability of the Department of Defense to conduct research, development, testing and evaluation, and operations, or to maintain military readiness." Congressman Steny H. Hoyer (MD-5), praised the action by the Defense department and stated that the turbines posed "a significant threat to the mission and world-class stealth radar system at Patuxent River Naval Air Station."
The U.S. Navy officially objects to the proposed Great Bay Energy wind facility due to unacceptable impacts to military radar at the Patuxent River Naval Air Station. The text of the letter is provided below. The full letter can be downloaded from the links on this page.
The long-anticipated response from the Department of Defense on the proposed Eastern Shore wind turbine project was released Thursday and it is so strongly negative against it that it could very well deep six it.
Reeves said when Smithfield and Morrisville fire departments arrived at the scene, it was determined the generator housing was ablaze, sending flames up the tip of one of the blades. The departments determined letting it safely burn down was the best course of action.
