The Making of a Wind Turbine | Exceptional Engineering | Free Documentary 

huh? what you say????

Luckily coal plants today are about 85% efficient. With the new natural gas plants (used primarily in the summer time when air conditioning is used by most people) are 99% efficient. And total pollution of a coal plant, what is released into the atmosphere is less than 5% of the coal burned. The problem is the "sludge ponds" where the particulates (unburnt coal) are captured and not released into the atmosphere or waterways. What to do with that is still a bit of a problem. All pollution is "unburnt fuel". More efficient engine, and better use of the fuel and theoretically cars with combustion engines using gasoline could also reach 85% efficiency. Right now they are 25% efficient. Meaning out of every tank of gas you purchase, you only get to use 25% to move your car, the other 75% is pollution out your tailpipe as "unburnt fuel". Yes, every tank of gas for every car purchased wastes 75% of the fuel purchased. That should be completely unacceptable. But the "industry" won't let people know that truth. If we are serious about this "global warming" business then why is the tech not offered to make cars pollute less, and get more MPG? Combustion engines theoretically could release 0% pollution, if done right. And there is "No" shortage of oil in the world. Saudia Arabia alone found another 660 billion barrels of oil in their reserves. It's because the oil fields that have been pumped for oil, are refilling on their own. But if the public knew that there is no shortage of oil then they can't rape you at the gas pump. Which indeed is happening for everyone throughout the world. Enough money, billions and billions of dollars, is never enough is it? They always want more. Even though none of them have figured out a way to take it with them when they die.

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?

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.

Always wanted to know how they connect to the grid.

GREAT questions.. we need a video cover jussst this alone

Lovely and space to work on, well thought out

A huge pile of useless tech.

Useless tech,rubbish.

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.

What is really amazing about it is it makes no mention of all the negative aspects of wind turbine.

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

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!

How much are THEY paying you to stay home and NOT Work?

Because the end of the world is coming and they wanted to convey it with some Hans Zimmer music., LOL

The gluing was redundant with the cables running through from top to bottom. Waste of money and man power.

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.

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

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

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.

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.

I know some little people. They prefer to be called midgets

Must be nice to get paid to do a workout instead of paying to do one!

@niels lund The method to show how the cables are tensioned and fixed down is omitted.

I know! I thought I was the only one going crazy with guy kept saying screws!

I know that was driving me nuts. Screws to hold that heavy equipment in place. Lol Stay safe bro

"machine screw"... look that up and wise up...

A machine screw is a screw or bolt with a thread type which accepts nuts (or other types of twisted on locking devises) possessing the same thread dimension. Example : a 6-32 x 1" screw would take a 6-32 nut..... and..... a 1/2-20 x 5" bolt would take a 1/2-20 nut. BOTH of them have "machine screw threads" and can be called machine screws. When the fastener in question has a shank diameter of 1/4" or larger, it's referred to as a BOLT.

The explanation for the use of the word 'screw' is that in German, the word 'Schraube' means screw and/or bolt and whoever made the translation was not aware of the distinction in English.

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.

travel and see What is your Site?

@@danijelhorvatincic9224 i build them from scratch..in north Dakota

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.

Image screwing one of those screws in your wall to hang a picture.

😊 😁 scrap farms...

Funny then why are massive companies investing large amounts into wind. Dont listen to everything you see on the internet

@Vladimir Birukoksukker - hmm.... let's see... Vestas, revenue for 2019 is 12.15 BILLION EUROS, which is over 14,000,000,000 USD (BILLION, son) and they a strictly a manufacturer, seller, installer, and servicer of wind turbines.

hi tensile blts

Bolts are screws

I said the same thing. Lol

They could be set screws if the thread goes all the way down to the shoulder, they’re only bolts if there is a decent shank

@@lollollollollolrofl Agreed

Which amazing man ?

Was discovered thousands of years ago

grindupBaker humans that discovered it.

Exactly this hard work and technology for 7,000 washing machines.

... for making such an in-disposable mess.

Useless tech.

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.
