Exceptional Engineering: The Making of a Wind Turbine | Engineering Documentary
Electricity harnessed from wind has become the second largest source of energy in Germany since 2017 - and has thus out powered nuclear and coal. Nearly 30,000 on- and off-shore wind turbines are operating throughout the country, covering approx. 19 percent of energy consumption. Our report follows the construction of a new wind power plant in Falkenthal in Brandenburg. Once installed, the windmill will be 179 meters high, supplying up to 5,000 households a year.

Невероятная конструкция! Такие размеры, это фантастика!
huh? what you say????
Thank you Free Documentary for uploading this video. This video was one of my best video in your video list.
glad to be a wind Technician who gets to travel all over the world to work on these beauties.
Do you know how to use a caddy program?
@@Priestley777 I’m a Torque and tension lead tech I don’t work with any software or electrical components. I save that for the smarter fellas
Wait really you get to travel around the world. I thought if you were a winglets tech you just stay within the country ?
@@jaysonemile6633 I work for a polish company company and we travel across the Europe to work with these turbines. It's absolutely fantastic although they might be a bit of a language barrier in some countries.
@@xJakeeyy you tell people how tight to turn nuts?
Incredible Efforts involved in assembly as well as in manufacturing of wind turbines.... Thank you for this awesome documentary.
A huge pile of useless tech.
Great and interesting documentary, thanks for uploading!
Useless tech,rubbish.
Amazing documentary! All the process is more or less explained. Now I'm curious about the offshore assembly proccess.
What is really amazing about it is it makes no mention of all the negative aspects of wind turbine.
America and here in Canada has huge open spaces in the prairie states and provinces, in the near furniture i see while wind farms being build with hundreds of wind turbines.
People in cape cod have fought off shore wind turbines for years because they don't want it ruining their view. I guess they prefer the air and water to slowly become poisoned. I think wind farms are beautiful. Not the safest thing for birds but evolution will sort them out.

I love these types of documentaries💕💕🧠🧠🧠🔂
I wonder how much energy it takes to produce a wind turbine? From raw material to finished product including transportation.
It takes like half a year for a turbine to recover the energy invested on it's production and installation. They are really efficient.
And how much it costs to maintain. The industry claimed it would compete with other sources, but in the end, the customer pays the same regardless...
@@Shnick in the UK, wind has now got so cheap that it is now the cheapest source of electricity in the uk, and is now forcing all coal and some gas plants out of business
@@danchang9976 But that isn't true. The only reason coal and gas plants close is because they are disadvantaged compared to special treatment that wind gets financially. First if wind energy is being generated then it gets first priority for use (it HAS to be bought by the electric companies) - so in windy weather the gas and coal plants have to 'stand down' and they get no compensation. But if it is so windy that all of it cannot be used then the wind companies get paid even though all the wind isn't used! This puts coal and gas at financial damage. Also what happens when the wind doesn't blow? We just had a week of that in UK (Nov 2020) - wind never got above 5% - it was only gas, coal and nuclear that kept things running, otherwise we have blackouts. Same every day actually it is gas (only) that enables power to ramp up as everyone wakes up in morning,
@@TheChrisEMartin yes, but it also means that consumers get cleaner air to breathe and lower bills as wind is now cheaper than gas and coal. Coal and gas is outdated tech, every utility company knows that and that’s why coal will be gone by 2024 at the latest and gas will follow suit in about 20-30 years. Nuclear provides a base load in our grid, followed by wind and solar. After that gas, biomass and hydro is used and if their is still a demand for more they use coal and move some gas plants over to peak demand scenarios where their output changes depending on volatility. It’s outdated tech, it’s going, don’t defend it it’s gone.
This is very good. I had to stop and check comments for calling parts screws vs. bolts. If I'm wrong so what I'll keep watching
EXCELLENT documentary. I'm now up on CURRENT events.
"We used to glue the rings together but we stopped doing that for efficiency..." thats reassuring...
The gluing was redundant with the cables running through from top to bottom. Waste of money and man power.
15:15 nice interior & sign design
Lovely and space to work on, well thought out
Thank you. You've done a great job. May God bless your work.
چقدر جالب وقشنگ وبزرگ
This channel is keeping me entertained and educated in quarantine
How much are THEY paying you to stay home and NOT Work?
Incredible!
DREAM JOB WOW THANKS FOR THE VIDEO
So little about the concrete foundation and anchoring! great documentary anyway folks! many thanks for sharing it!
I like to watch this channel videos. In depth detailed documentary chennel.
37:00 you see white bracket lying down on the mold fiber 37:23 you see the bracket crushing the fiber glass
4 hours and 20 minutes to build each stage. Interesting number.
The propellers look pretty cool in a huge pile in west Texas.
awsome engineering. Bravo!
We need thousands more!!!
Look up what happens to wind turbines when they are disassembled. They literally bury the parts in the ground because the parts are nearly impossible to recycle... you may rethink just how green this is..
@@WARHAWKLEADER1 Impossible?? Didn't knew that... Just like eletric cars fuck up the environment with lithium and sulfuric acid for batteries
@@justicewarrior9187 An electric car battery is 100% recycle-able also look at what oil has done to the ocean and how many wars have been fort over it. Also when you make petrol from oil you need to put cobalt in it to get rid of the sulphur and when you burn that you can't get it back.
STUNNING
Good Show
The blades are very reminiscent of the A350 sharklet. That's some sexy engineering!
That dude said "magnets are spinned" at 27:16. Lol
This video was very informative.👍
EXCELENTE DOCUMENTÁRIO - FORTALEZA - CEARÁ - BRAZIL, 31-08-2020
Amazing documentary!
That's 4 Hours and 20 Minutes at each station. Definitely a salute to 420.
Excellent documentary.
Thanks very much....!
very nice videos I'm watching your videos from Athens Greece .
Fun video except fore the recap style editing. Hate that. I just watched the same info from 12 minutes ago, I'm not a toddler, I can retain info for hours sometimes! lol Also, tons of info left out. How do they keep cool? What is a typical failure look like? What does a catastrophic failure look like? Show how the connect to the grid. Show how they stop, start, turn. How do they test the motors prior to shipping? How do they affect local Eco-systems? How about a map showing the amount of homes covered by a "typical" year's generation. Then show amount of space required for turbine-to-home ratio scaled-up. Meaning show space needed to power NYC or London in a typical year. How many, how much space at what cost, etc..? And how about recycling of old units? How much can be reused?
Always wanted to know how they connect to the grid.
GREAT questions.. we need a video cover jussst this alone
Espectacular.. es impresionante como no pueden trabajar con vientos superiores a 6 m/s, cuándo en las zonas dónde se van a instalar es porque es muy ventosa...
Great video 😊
13:30 close up shot with intense music had me wheezing, why was that needed?
Because the end of the world is coming and they wanted to convey it with some Hans Zimmer music., LOL
Thanks for uploading this amazing documentary.
Fantastic documentary Thank You 🎃.
Great documentary
My younger brother has been working on wind turbines for years ,now I know why he is so fit and strong !! Amazing to see one come together !!!
Must be nice to get paid to do a workout instead of paying to do one!
as someone who involved in planning of the Wind Turbine being transport from Local Port to mountain Range, I can honestly say the process is not easy at all!
What kind of engineers are needed in the field ?
@@huesenpaul1394 Geotechnician, Site engineer, Service engineer, field engineer. etc...
@@joex8au04 oh ok. What would say are like all the parts of the wind turbine and like match the subject. For example for the wings you would have to know about physics or something right ?
@@huesenpaul1394 There are many different factors involved in designing such complex systems, several different types of engineers find work in wind energy design. These include aerospace, civil, mechanical, electrical, and environmental engineers, among others.
Morris CH yeah that’s true I really wanna get into aerospace engineering or mechanical engineering when I go to college. Ok so name the 4 main elements then.
This is amazing!
Impressive
Spinned? The word you are looking for is spun!
Im glad someone else heard that. I could not stop thinking about it for the rest of the video
Right - and he doesn't know how to pronounce epoxy ("e-poxy"), nor the difference between a screw and bolt. Still, it was very interesting despite the limitations of the script and narrator.
pardon the PUN.
GOOD, THOUGHT I WAS THE ONLY ONE THAT CAUGHT THAT...
Thank you. You can also add "unwound" instead of "unraveled". Worst narration EVAR!

I’ve enjoyed every second of this. Thank you
Amazing!! Thank youu
amazing
Very impressive turbines made by very skillfull people and their high tec equipment. 😀 Det er rigtigt flot klaret at i kan lave de kæmpestore vindmøller i Danmark.! 💕
who else came from a video called “top ten wind turbine fails” and before that, came from “windmill destructed in storm”
😂😂 Yep
Haha how did you know?! 😂😂
Kate Malfoy me
Not me. Before this I was watching a documentary on the declining bird population in America. Somehow it switched me over to this video.
I searched up this video, but before that, I had watched those videos.
Good Engineering Documentary .Thanks
Nice !
A wind turbine comes to the end of its lifecycle after about 20-25 years. While 99% of a turbine's parts can be re-sold and recycled, the majority of turbine blades are a challenge, so much so that they end up just being buried in a giant 'graveyard of blades' landfill. In the U.S. over the next four years alone that will be the fate of more than 8,000 blades.
It would seem that as technology grows, our footprint grows exponentially. Therefore, the BEST way to slow our destructiveness is to physically StOP consuming so much energy. The basics of life use to be rewarding. We've somehow lost our way.
they now recycle some so that will grow until no landfill is needed
Absolutely fascinating. Loved it. Has anyone calculated the energy to make one of those? How long to pay back the "embodied energy"?
The lastest Wind turbines are Suppose to recoup construction cost and energy in under a year. And then last another 25+ years
They never will recoup all the energy that went into them. Impossible.
@@flexairz you have some information to share on the subject? Or is that just your opinion?
@@johnv341 inflation always seems to fenagle its way into even the deepest of pockets. I cut mine off 😂
@@flexairz It would be interesting to see a cost benefit analysis. Electric in Europe is very expensive, with the exception of France, which uses mainly nuclear power.
Vivo eso documental muy bueno
really awesome.....................
While traveling through Kansas i wondered how they hung the turbine.... now i get this video in my suggestions. Seems like my phone can not only hear me, but read my damn mind too. 🤨🤨🤨🙉🙊🙈🙈
Yeterday I waslooking for someone to tech me the Colombian Cuatro...today I get a guy playing the Cuatro, suggesting I buy some car or other
Apps spy you every second, google, youtube,facebook....
@@user-og8hp2qu5f VPN!!, no social media. Unless you call KZhead social media.
I guess they use post-tensioning steel cables to secure the tower, instead of bolting it together. It would've been interesting to see how the cables were tensioned and anchored to the foundation.
@niels lund The method to show how the cables are tensioned and fixed down is omitted.
awesome
an awesome documentary!
Glad you enjoyed it!
i guess we will never know how the cables get anchored lol
Seems like it's a trade secret
I wanted to see that instead of stacking the segments on top of one another.
*Those cables were used to anchor the 83-meter concrete stacks. For the other steel sections that they added on the top to reach a height of 136 meters, were they also anchored to the concrete sections or just stacked up? I guess they were bolted to each other. Can anyone clarify that, please? Thank you.*
i had totally forgot all about that part
A
I was once standing right under a turbine, it was surreal..
Chen Yes me too! It’s almost unreal, and the noise it makes is so eerie.
@The Curious Mind I can - where I live we are not far away from the biggest onshore farm in the UK, where they have both Siemens and Alstom turbines. You can't hear them at all until you are fairly close, 50 metres or so, is the first thing I will say. There's a hum from the generator and electronics, quite similar to what you hear if you're next to a transformer. You a low pitch "swoosh" every time a blade passes by. Also on these ones they drilled a small whole through 1 blade on each turbine which gives a little whistle - that discourages birds and bats from flying too close. The other noise you might hear is a knocking. That's from the guy trapped inside ;) no what that is the yaw drive. Because the motors are very underpowered for the mass at the top the turbine changes direction very slowly, and that noise is just the yaw gear travelling from tooth to tooth. Hope that helps!
@@danijelhorvatincic9224 Thanks, I'm not in this industry lol. Those wind turbines are just common in my hometown, somewhere in the southeast corner of Shanghai
Great video
Amazing.
The size, the complexity, and the expense! Amazing.
How much energy does it take to make and build these things and at what point does it become cost effective?
I've wondered that myself, and others have asked. But part of the whole wind-power is to reduce burning coal and oil....
@@dougankrum3328 People don't realize is how much coal & oil is required to fabricate, install and maintain them over that 20 years. That same coal & oil would have produced 5 times more electricity than the wind turbine will make in its lifetime.
@@Tadrjbs I'm sure you have a scientific source for that? I'm especially interested in that last statement.
@@SkullRaven Experience source, worked for Cant Name Wind for 10 years. Just to change ONE O-ring on one blade hub takes 300 man hours and 300 gallons of diesel and 180k$. There are 3 on each turbine. The units near the ocean have to be changed more often than inland but turbine output never even comes close to install and maintenance...and 5 times is a conservative figure. It doesn't even include eroded blade changes. Much more environmental harm then is allowed to be exposed to public on top of that.
It will never pay off.
That was fabulous
It's fantastic.
Been my career for a decade. It's amazing how little people know. Or how much they think they know.
I know some little people. They prefer to be called midgets
nuclear reactor : hold my beer
This is just amazing! Technology and the human being will power! Amazing!
You really would find many of my ideas over the top but logical and simple to understand.
KINDLY ALSO MENTION EACH WIND TURBINE PRICE WITH INSTALLATION.
If you have to ask, you can't afford it...
About 1.3 million dollars per MW of capacity. Most wind turbines are built for 2.5 MW capacity.
The Thor windfarm in Denmark will cost 15,5 billion DKK and have a output of between 800 and 1000 mw, it will probably be around 100 wind turbines, so its around 155 million DKK per wind turbine if the price of the connection to land is divided equally between each wind turbine.

In Construction Simulator game the wind generator is a prized achievement, but is time consuming and difficult.
Estos documentales me gustan, deverian tradusirlos al español👍
Love it
How do the wires going through the tower get tightened? looks like they left that out.
Georgw Marhevka. No they tight those cables with some special tools there so many industrial things made to this purposes I know cuz I been working not for wind turbines but for the electric industry so we use cable s and many things
I agree that it would have been nice to see the cables secured. Look up “post tension concrete” or something similar to get a basic idea of how it would be done.
It's a Similar procedure to tightening cables on suspension Bridges. As long as the cables are all equally tightened. It makes the structure very strong.
Company secrets 😉
27:15 "magnets are spinned around the copper" SCIENCE!!!!
Nice work . thanks
Them are some pretty big screws!!! We call them BOLTS here in the Appalachia!!!
Image screwing one of those screws in your wall to hang a picture.
That Explains it, the most expensive Source of Energy 🤗🤨
And how many people do you think it takes to maintain a thermal or nuclear power station!?
not agree with u, more expensive is a coal\gas plant, nuclear plant. maybe solarplant too.
They are called bolts not screws
Only in your tiny little world
NERDDDDDDDD!!!!
Ignore these other two pleebs, that was the first thing (from many many errors in descriptions) that bugged me too.
Lane Shurtleff if that bugs you, you’re part of the problem. Zane H If you call them bolts, then thats fine, I normally would too, however, in Europe (and Asia) they call them screws. In some places around the world, the word screw is used as a noun, and bolt is used as a verb, and vice versa in other places. For example: next we bolt it together with these screws. I repair very large mining equipment and spent years manufacturing it, and the general rule of thumb in our area is that a bolt is used as an assembly with a nut and washer, while a screw doesn’t use a nut, it is “screwed” into something, however when we deal with our German counterparts, they just call everything with a thread, a screw. So my original comment still stands: in your little bubble, they’re bolts and everyone who disagrees is wrong, but in the real world, it doesn’t matter. Q. What are you if you are on an incline plane, wrapped helically around an axis?
9:30 In my part of Europe they are screws if fully threaded and bolts if only partly threaded. Was hard to see but these look to be partly threaded so bolts.
