Mega Construction: The Creation of Gigantic Wind Turbines | FD Engineering

[@lindamitchell-fox1926]

How long does it take to recover the cost, what is the yearly maintenance cost and how are these huge structures recycled/reused/repurposed when they have reached their useable lifetime?

[@tasmanianduval1931]

Look up abandoned wind farm. A lot of times they just become decrepit and left alone. Kinda sad really.

[@woutervanduijn4331]

They never recover the cost is the short answer. The long answer is way more complex but in short normal people get screwed over while the wealthy get wealthier.

[@spidermight8054]

Those weren’t 30 mm “screws”. They were bolts! There is a difference.

[@JonDingle]

Actually no, they were neither bolts nor screws. The men threaded in 30mm threaded bars. Because no head was on the top, they were not screws. Because there was no shank or head they were definitely not bolts. Bolts have a shank and a threaded section, screws are threaded virtually all the way to the head.

It's not the diesel fuel that is the real problem. It is the effects of mining and material processing that has to occur on a vast scale to get all of the materials needed for renewable energy to work. Then it is claimed in pure hypocrisy that nuclear power produces too much waste and that uranium mining has too much impact.

Amazing. I pass a wind farm every time I go to my vacation home out of Tehachapi, Ca., but I don’t think they are this big. Then again, they seem to be replacing them often, so maybe the newer ones are as big. I doubt it though. We certainly don’t have any offshore.

[@kitemanmusic]

@2:30 Each weighing around a tonne! Check this error! I would guess 30 tonnes. What is the break-even time for a wind turbine? Why can't they abseil down? Very impressive engineering all round.

[@hobbelundahl6249]

A windturbine weight between 240 tonnes and 303 tonnes. In addition to the wind turbine itself, around 750 tons of concrete and 40 tons of steel and iron are added to the wind turbine's foundation. That means they weight atleast one thousand tonnes. Your 30 tonnes are not even the blades wich weight atleast 11 tonnes each...

[@kitemanmusic]

@@hobbelundahl6249 I meant 30 tons for each section of the ring. However, much it weighs in total is an incredible amount of material, and in my view, a waste of money

[@hobbelundahl6249]

@@kitemanmusic Ah. Kisses all over. I am sorry

[@nchw68]

47:17 Uhhh, no. Gravity shifts the rotor assembly to the vertical position and it is pulling the workers towards the tower. The workers are slowing the movement down for safety reasons. This channel has a problem comprehending simple physics.

[@hotwheels70]

The energy required to produce 70 tons of steel and 700 cubes of concrete per tower, also transport and installation would exceed what the turbine could produce over it's short lifespan. Nothing green about 'renewables'.

[@Maxpower50000]

That’s not true at all Even assuming the turbine only produces power 50% of the time in a 20 year lifespan it will produce over 125,000 MWH 70 tons of steel about 350 mwh A barrel of oil about 1.7 mwh and 0.4 barrels per yard of concrete. Thats about 500 mwh Materials are under 1,000 MWH. You are still up over 124,000 MWH So many variables to these numbers but you aren’t even close. These numbers are only getting batter as wind turbines are constantly getting more efficient.

Unbiased opinion correction

[@alexanderpasnl]

No need for that. Almost 9000kg of resin for one blade alone, not even counting the fibers. Three blades for one turbine equals almost 27000kg of epoxy resin and there is no way that can be recycled. In 20 years that is pure waste. Sometimes is just obvious that numbers aren't adding up. This isn't environmentally friendly. There is so much more negative about them. The enormous noise pollution are making hundreds of thousands people ill. Every day thousands of birds are killed by the giant blades... Just to name only two things

[@jacquesah-ki721]

Great engineering but made possible by coal and oil. Once we stop mining these, I wonder how they gonna build and transport these wind turbines.

[@LLcreeker]

sad reality that the leftists cant seem to grasp. heavy industry and trucking will be dependent on hydrocarbon energy for the foreseeable future. golf carts just cant get it done. look at the current EV "trucks." only good for hauling potato chips and moving trailers around the shippjng yards. lol

[@johnhenrick2298]

I fail to see how they can pay for themselves in the amount of electricity they generate. Obviously, erecting them is not the final stage; they all have to be connected and the cables run to the grid.

[@AlanWilliams-su4bs]

I understand that the bigest turbines can power an average home for a day with one rotation of the blades. I am invested in a medium size wind farm in Scotland. 8 turbines and 6500 investors. Some are business and hotels. It’s just waiting for the grid connection and testing.

I like the idea use energy of wind, it is also old school, like wind mills. But use composite blades is totally unacceptable. It is not sustainable. We should use much smaller wind turbines buld with sustainable materials on top of every house. This scale of "green energy" is totally not green.

@@asbestosfiber I would disagree with you on negative impact when it comes to long term because they kill more birds per year than pretty much anything else out there man made and the amount of energy required to manufacture and transport them has to come from somewhere and it's probably not enough to offset the amount of so called green energy since they don't produce all the time and have alot of downtime for Maintenance there were alot of people who froze to death and suffered in Texas I believe because the wind turbines froze up and couldn't produce energy and alot of the grid was transferred over to it. I would say when you take everything in it's just not to positive.
