Re: [With Pics] The Bay -Approved for wind turbines in Waterloo said by ArthurS:DJ, I've worked with structural engineers plenty of times on wind load issues, I also work with rigging structures in the entertainment industry (think huge outdoor events/ concerts), that's cool...that is another up and coming part of our industry too...the entertainment industry is using a lot of our products at concert events (large automated curtains or other animatronics used at concert events).

said by dirtyjeffer:if you look at quality MODERN turbines, you will see that these incidents are almost non-existent. Anything mechanical will eventually fail, this is why fault analysis is performed, and why designers spend a lot of time figuring out the MTBF on the products we use daily. Maintenance can be quite costly on these turbines, but is necessary, but does not rule out the rare premature failure of an important part. We see this with the cars we drive. |

London, ON | i think some of the big named wind turbines have an expected life span of about 30 years (keeping in mind, the larger units only spin at about 12 RPM)...that's a pretty decent amount of time...especially if these ones in the video's are failing at about the 10 year mark.

California has been using them for the better part of 30yrs probably longer closer to 40, really I haven't heard about any catastrophic blade failures or anything. I know they happen, but usually it's due to some odd circumstances such as blade failure, caking, misalignment, mechanical failure or other things. Most of the ones that are in use now auto brake and lock above a specific rpm with wind speed.
When I was a lot younger, I was down in the San Bernardino(San Gorgonio pass) area and got to see the massive windfarm project upclose it's pretty amazing, it's not the only one in the state however California makes for an excellent area for it. And if you've ever been there, the winds can really pick up hard and fast. |

said by digitalfutur:How much power to these turbines output? Seems like a lot of PR rather than substantive energy reduction. My guesstimate according to what I've been reading these should output on average about 330Kw/month so times 2 about 660Kw. That's about half of what I use for my home per month.
At least they're doing something about it, frig it took 20 years to change the clothesline bylaw. You don't need to look any further than Germany to show how successful renewable energy can be.
»www.german-renewable-energy.com/···oot.html
"Renewable energy accounted for 5.8 percent of primary energy consumption in Germany in 2006 and the share of renewable energy in total gross electricity consumption rose to 12 percent. Some 214,000 people are now employed in the renewable energy sector and may have managed to prevent some 101 million tons of carbon dioxide from being released into the atmosphere in 2006."

said by dirtyjeffer:the various manufacturers websites...25 years or more isn't uncommon for a quality turbine...of course, routine maintenance will be required, for any turbine. They should run for 3 years without any maintenance, these are not the same as those giant turbines, I'm sure that after 10 or so years they will simply replace the blades.
said by Thane_Bitter:Wow - Given the emptiness of the parking lot, they might be the only revenue generators they have. that's because they're not open yet, they open on the 19th.

Was watching the story that was on CTV and they mentioned that there will also be a turbine installed in RIM park.

Also like how they called the story, "winds of change"  |

ArthurS, that installation was reported as being 10 years old at the time that it failed. Here is a danish news report about the event »jp.dk/uknews/article1277616.ece
If anyone is interested in the more classic & picturesque low speed wind turbines, I recommend this place:

It is a wind powered saw mill near Bayfield ON, very neat to see the inner workings.

said by dirtyjeffer: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.

Regardless of the dubious benefits of having a wind turbine in everyone's backyard, (it's much more efficient to have a wind farm outside the urban area), failures will happen. It's a statistical certainty. Spinning blades and shingled roofs do not mix.
The implementation execution of new technologies should not be simply accepted a face value because "it's for the environment". That's the fast track on the road paved with good intentions that ends with policy disaster.
