You should be absolutely ashamed of yourself for posting something as unintelligent as this, William Lyons!!!
And if you don't know what I mean, William Lyons... stick to serving fries at McDonalds!!!
Last one broke for sure
Untwist itself ? Don’t they have slip rings ?
No way to put out a turbine fire.
They only last 30 years.
Wow masahallah will don very nice good job My brother 💝 love from Pakistan 🇵🇰🇵🇰💕🌹💐🏏🏏
I am 17years I wish be renewable energy engineer in future we'll come to Egypt ❤❤🇪🇬🇪🇬
The most problematic parts are the generator and gear box which are "cooled" by being full of petroleum oil. Great! That and lightning...even better to destruction of a 7 million dollar 8 to 12 year lifespan, inefficient, highly flammable, unreliable electric generator. Wow even better 😅
The best presentation ever🔥🔥🔥🔥
Is it Location of transformer near of generator Or in bottom
Good job
🎉
Wow so much engineering you have all the areas covered nicely done
This is the kind of guy I would want taking care of this machine. Sounds like he's extremely competent.
There is NOTHING "green" in these infernal machines, Denmark is about to be totally destroyed by these infrasound noisy infernal machines, there are a few people with very deep pockets who earn fat from this scam..The man stands and says that the system itself uses a little over 1Kw before the turbine starts making power!!! it is not a little power as he says, it will be a lot of power during its lifetime, when you see that these hellish machines stand still 60% of the time because agreements have been made to purchase power in other countries, that is that's a scam that wants something, it's unbelievable that people can't see it's a scam of the worst kind, these machines never turn green, blades are buried because they're so toxic that they can't be recycled!!! Well, it's great to get poison in the ground, isn't it! if you look closely, you often see oil leaking out of the clutch where the blades are fixed, if there were finally to be this kind of crap to make electricity then you shouldn't install more than you need, it's too stupid to keep putting them up just because there are people with deep pockets, One of the world's best sound researchers is called Henrik Møller and comes from Denmark, he once said that there MUST be at least 80km to the nearest habitation because these turbines make so much infrasound that people and animals get sick from the noise from them, we get the disease Hyperacusis and when when it hits it's too late to do anything about it, Denmark is destroyed by the noise from these crappy machines, noise everywhere from them plus Denmark is looking like a pilot site for wind turbines, no matter where you look you see these machines in the countryside .

This has been my go to video for terrible insomnia
EXCELLENT! Thanks for posting this.
Glad you enjoyed it!
23% capacity factor is terrible. Nuclear is 90% or greater. At 1.7 million euros per 850kw, it would take 8 billion euros worth of these to replace 1 1000mwe power plant, in order to match the mwh equivalent per year. That also doesn't include the lack of reactive power made by wind generators. They have very poor power factors when compared to large synchronous machines.
From my time at Vestas. Great memories
Too bad they are a waste of money.
Pity the system that turns the blades in to wind was not shown or demonstrated yet its a vital part of the system.
No mention of the inverter?
Yes if you build something wrong you have to compensate that with other things a fact is just useless things, he is talking for 5 years its ROI for building that thing that is not incl themaitenace, a ROI from 1 year can be done but not with this, simply a waste from time money and land scape, thanks for showing how stupid it is.
Neat stuff, thanks for sharing.
Our pleasure!
Thanks for your sharing
Thanks for watching!
I´ve never seen a cost/benefit analysis ...
A lot has changed since me working on the 250 KW models in the early 90's. Very happy to see, the Midas display and keypad has remained the same. Thanks for showing us around. Thank you.
Thanks for sharing 👍
Doesn't anybody realize how many people get cancer every year from the noise of these turbines. It's a tragedy that nobody but Trump can fix it. Ask him about it at one if his rallies.
These eyesores should be nuked from orbit.
👍👍
Is the rotor of the generator just permanent magnets made of rare earths? If it were made with windings and an exciter, how much less efficient would the conversion be? How is the yawing mechanism locked out when people are in the nacelle?
Yaw gear, looks like a worm gearmotor going through a planetary gear.
Now I can see how they catch fire. Very interesting to see, dont think I would want to be in there with the blades turning
The first one has a critical mistake in its design- there are primary members that won't be activated because there is no rotational restraint at the end supports. The second one is a good minimal design that addresses the main forces. The third one is a straightforward design but would not be as efficient as the second. The fourth one addresses the forces well and appears to be very stiff. The fifth one again makes a mistake by trying to use end rotational restraint that isn't there. The sixth one is a basic truss and will work well if they have executed the joint connections well. It's also going to be very stiff. The last one has a critical design error by not bracing 2 of the truss panels, when they load it you can see excessive local deflection across these 2 panels. Overall though it looks like a lot of fun.
Would this be before it destroys its blades or gearbox and burn down
Thank you!
You're welcome!
At 4:06 did you see that beautiful red tailed hawk get taken out by the blade? ....
Very good video
Thanks for the visit
I live in northern Oklahoma, USA, and these things are everywhere. Some are very close to the highways and the size can be appreciated, and encountering a blade being transported really brings it home. Thanks for the tour.
Thanks for sharing
Thank you, no annoying music or fancy effects, just interesting facts.
Why doesn't it turn to face the prevailing winds? Wont this affect its ability to provide sustainable energy, or is the whole shebang a huge con????
I'm no expert, but he described a pair of motors for yawing the turbine, and he said it could turn to any azimuth. So no doubt, the control system points it into the current wind.
The stupidest invention ever.
Your life is a stupid invention, but you don't see most people complaining

Thank you sir for make and offer video safety protection.I am support your video.
The turbine has not paid for it's self yet! The 40% subsidy is a cost to society and part of the true cost...plus you did not account for the time value of money.
It has
The weak link was the thin board. The solution is to distribute its brittle surface across as many contact points as possible. That means a latticework. The trestle bridge came close.
I love this job technicien repair of ÉOLIENNE
The first windmill I built was vestes v-15 in Tehachapi victory garden. Zond
Bird killing machines are wind turbines + all the wind turbines in Scotland only put 3% into the national grid last year it just doesn't work.
