Re: [With Pics] The Bay -Approved for wind turbines in Waterloo »www.youtube.com/watch?v=c3FZtmlH···=related
said by dirtyjeffer:those look fine...someone remind me why they weren't allowed in the first place?? 
Yes I know, not very likely to happen to 'the Bay's' installation (and the video is an extreme example of a failure):p

London, ON | i think that is an unrealistic example of what happens with a wind turbine (unless someone made their own)...it should NEVER be spinning that fast...wind turbines generally don't spin very fast at all, as most have gears inside to make the generator spin at a decent speed...perhaps this one was a "direct drive" model, i don't know, but either way, the blades are supposed to adjust to the wind speed, so if the wind is blowing hard, forcing the turbine to spin faster than its safe rotational speed, the blades should turn parallel with the wind, preventing them from "catching" the wind meaning they won't really spin at all...most are also equipped with some sort of brake to lock them during this type of scenario...of course, who knows what really happened and what brand was used in that video...also, it might even have been a staged video, made to "scare" people about wind turbines...our company is quite involved in wind turbines and that type of "failure" is unheard of any of the companies we deal with.

If you click on the actual Youtube link and read the description, they specifically mention it was a break failure and this would otherwise not happen.
Edit - wow, I should probably read the entire thread before hitting reply, hah.
