Lake Land College removes, disassembles damaged wind turbines

Lake Land College has removed two wind turbines after they suffered enough damage to render them inoperable. "The situation with the two 100 kW wind turbines is a snapshot of renewable energy in the United States in 2017," said Joseph Tillman, the division chair and Lake Land College's renewable energy instructor and coordinator. Wind is going to be around for a while, but other forms of renewable (energy) are gaining in use.

Blade breaks off wind turbine east of Enid

The cornfield belongs to Ken Carpenter, who declined to comment. Cleaning up the blade and wind turbine could take anywhere from a couple of weeks to two months, and will involve bringing a large crane near the field to take the blade off, McIntyre said.

Hundreds of Tuscola County wind turbine motors being replaced, design flaw blamed

Gauger said it’s been determined that the “old style” keyway pitch motor is “defective” and not able to handle the load that is being placed on them by longer blades. He said the motor is essentially trying to adjust itself so that there is less drag. “What happens is on the upswing or the downswing, it’s actually got some slack in there and that’s that clunking noise that people are hearing,” Gauger said.
