On a calm, sunny day last June, Mike Willey was feeding his cattle when he got a call from the local sheriff’s dispatcher. A motorist had reported that one of the huge turbines at a nearby wind farm had collapsed in dramatic fashion. Willey, chief of the volunteer fire department in Ames, 90 miles northwest of Oklahoma City, set out to survey the scene.

Huh.
Must be commotio cordis.
Or Fentanyl.
Definitely a coincidence.
(See how THEY like hearing that)

But, are they falling
suddenly and unexpectedly?
That seems to be a problem that’s been going around..
Just like in the good old days e cattle rustlers, no trial/ hang them immediately.
People that have NO CLUE making huge decisions because they get a warm feeling about themselves that they ‘have a seat at the table’.
Because they had a toy whirlygig when they wore diapers???
And all the engineers and accomplices that’ve built this shit bear no responsibility? Don’t they have LICENSES to be engineers?
What do you want to bet they are all insured for double their actual value. So the company doubles their investment without ever making electricity.
Wind and solar have nothing to do with environmental impact, it’s all about money.
The bigger joke is ethanol, it cost more to make than it’s worth. Without all the subsidies, the ethanol production would end.
Engineers don’t need licenses. And licenses don’t assure good quality work. just look at doctors….
Ethanol subsidies start with the farmers. Have you ever been curious how much money they make? You can find those in your area here:

Here is the top 2, 1995-2020.
Riceland Foods Inc Stuttgart, AR 72160 $554,343,039
Producers Rice Mill Inc * Stuttgart, AR 72160 $314,028,012
The culprit here is “Harmonics”. Well that and poor engineering.
just look at doctors….
That’s why the call the Practicing Physicians.
Kind of like crop circles and cattle mutilations showing up in the middle of nowhere?
Are there corn fields nearby? Strange lights and loud shrieking sounds?
Sounds to me like the visitors don’t like ’em.
(Hold on. Lemme check my aluminum foil supply.)
They are no more practicing physicians. An acute care farce needs one physician’s license to hire physician’s assistants, nurse practitioners, yada yada.
Your physician retired when oBozo/Shitpants/Pelosi screwed us all. It was a historic BFD.
As to engineers, someone somewhere is accountable for the building of this historic crime. That the politicians needed culling decades ago is another layer of disgust.
If a wind turbine falls over in the middle of nowhere, does anyone see or hear it fall? TIMBER!
What’s a PETA member that’s also a militant environazi to do?
We need to prevent those making government decisions from any active (or known) investment.
I’ve seen “harmonics” shake a device into pieces. I’ve also “shifted” the natural frequency of a design by just adding a small weight at the right spot.
Jethro
Yep, regardless of the frequency. I’m curious as to what they’re making their “steel” uprights out of. But I’ll guarantee you there’s a sweet spot 72% of the way down that upright that ends up harder than Billy Hell. Snap.
However the one picture they showed was shaken right out of the ground.
They’re giving the bird dicers the clot shot, now?
“I’m curious as to what they’re making their “steel” uprights out of”
Ancient Chinese secret.
Jethro
I don’t know if you’re a cad jockey or not, but both Solid Works and Pro’s behavioral modeling packages are bad ass. It’s really cool to spot these problems at the design phase.
@brad
Ever use VIM VAR treated steel?
im past using Cad. I have the young punks do it. I used to use SDRC Ideas and Catia. today’s dynamic analysis tools are awesome.
Jethro
Yes, in 4340. Vacmelt. Interesting process. I’ve never used the stainless versions. A lot of the air frame parts for the B1B spec that stuff. It actually machine fairly well.
There’s an aluminum version too. KPS 1000. It’s a vertically cast aluminum in a vacuum that eliminated porosity. The cool thing about it is there’s no stress in it. So it lays flat no matter how you cut it.
On the plus side, they’re much easier to repair on the ground.
I use Solid works a lot. Our process is model up old airplane parts, dimension back to the print, and then use the model to drive tool path. A big video game. But I’ve been doing for a while and still get a lot of satisfaction out of it.
I’ve met some young snot nosed Cad Jockeys that are amazing actually. They’re like an extension of the computer.
I accidently got some prototype parts made out of it and didn’t know it. they were so tough they wouldn’t fail the life tests we ran. fooled us into thinking our design was good. then the pilot production parts were tested and failed miserably. it took months to figure it out. I call vim var steel “miraculum”.
Wasn’t able to get a copy of that DVRVACPAC Pic on imgpen.
Anyone out there got it an can re-up?
Appeared to be a well-balanced design.
I think you all are talking about resonant frequency and oscillation. One of my job duties was to run a vibration table. You hit something’s resonant frequency and it will literally shake itself apart.
@Wild Bill
yep.
As any electronic tech knows unwanted
harmonics & oscillation are a mother-f**ker !
Can melt down capacitors,transformers and vacuum tubes.
They can also send whale off course and they beach themselves on the New Jersey shores. Also caused by the big damn fans.
Wild Bill – Yep. Have you seen the vibration tables at NASA Lewis (now Glenn)?
They’re the biggies! When I was there they were driving them with a room full of HP Amplifiers.
