Mega Dams - Hydroelectric Evolution - Big Bigger Biggest
This film reveals the technological leaps forward that have allowed the world’s largest hydroelectric gravity dam, the Three Gorges Dam in China, to be built. The dam, that harnesses the power of China’s mighty Yangtze River, is over 2 kilometres long, towers over 60 storeys high, and creates a reservoir 600 kilometres in length. The concrete superstructure has a generating capacity of 22,500 megawatts of power, enough to supply electricity to 60 million people. At its peak over 25,000 men and women were working round the clock to make what was once Chairman Mao’s dream a reality.
The programme explores how this immense project was made possible through a series of five engineering breakthroughs. Six landmark dams, including the Hoover Dam in America, each feature a major technological innovation that allowed engineers to create bigger dams generating ever more hydroelectric power. Using computer-generated animation, we share the incredible stories behind these projects and the inventions that have allowed them to increase in scale. Six ingenious leaps forward that enabled dams to evolve, from BIG, to BIGGER, into the world’s BIGGEST.

Armstrong was a savage. Built an entire dam, ran thousands of pounds of copper, just for a couple of lights so he could have a few drinks with his buddies in his picture gallery.
All that trouble for one light? He ought to power the whole mansion, invent more efficient power systems. The house has central heating.
@broadstreet21 when you're that rich, I doubt you care about efficiency.
@@notanetbanger Not just money, but the time and effort to go into this.
He was Think imedyadley Hydroelectric. That important when u produced Semthing strong u must Turbin. Famouse Turbin.Smal or Biig.
Don't believe everything you hear.
I love shows like this
this should be watched in every school
Well this is a *DAM* fine accomplishment I’m *DAM* Proud to be part of a civilization that builds these structures It’s a *DAM* good feeling
"Dammit, Jim, I'm a Dr., not an engineer!"- Bones, Star Trek
Thank you for this documentary. Highly enlightening
22:42 "It actually took 5000 men 21 months to complete this dam (Hoover dam). It was completed 2 years ahead of schedule and under the budget" Credit where it's due. We could learn a lot from this
But didn't like a lot of those people die?
incredible. when there's a will, there's a way
The Hoover dam was built during the infancy of modern dam construction. I've seen the Hoover dam. It's impressive for the era but I could slingshot a rock across it's distance. The Three Gorges dam is 1.5 miles long. Let that sink into your perception.
Just watched a documentary, they claim 97 people died during hoover dams construction, but it’s not uncommon, and why they’re now paid well, more people die at work every year than have ever died at war
And killed the river
Dr. Andrews is a great chemist, love him!❤
A dam that's over 2 kilometers long? wow
It seems China is afraid of no technological obstical.
That's a damb long dam
@@mr.boomguy China junk that ruin the waters and the weather.
@@mr.boomguy Damn straight.
Absolutely amazing engineering of megas dams , but what happens if a bigger earth quake.
people die
What do u think
Dammit, Jim, nicely done!
Amazing. Very clever indeed. Make it all free even better. It can be done so why not?.
Have you tried to measure to see if you got tree elevation or inside rotations
Amazing!
Matatan.🤔. Ribirin HS, Great, documentary well done
Very useful thanks alot❤🎉😊
Now thats a Damn good Dam
I love hydro electricity Power plants
🤩Great Engineering
Love how hydro electric is called "clean energy" when the process of making the dams is anything but clean.......
Dams are bad news, period.
it's about how you need to make that dam (usually) just once. think how many coal/gas/fuel generator plants you need to replace the output of one big dam, and what is their pollution during their whole life cycle.
Human breath is pollution, too. So you want "clean", dismiss yourself first.
If you have a better more efficient way and currently practical way for electricity production then the world will beat a path to your door.
That’s a Dam good job 👍
Its an amazing engineering
Very exciting sound effects
My best friend, Great... We liked and enjoyed to the end. Thanks Have a happy day!
Wow! Very good and Beautiful excellent 😊💞
Wow its incredible realy I like this video
Here's another question can you release a different stage rotations like playing music on a piano try to understand if you can the concept of mountains different heist and directions and links
I went on a private yacht through the Panama canal. Just out there when i didnt realize how awesome my life was and has become
This video is pretty dam awesome
The Three Tofus Dam will be quite a spectacle one day.
I feel bad for those who will witness it in person.
26:03 rip camera man
If you go back and you look at the manufacturers of all your equipment being built in the background or does it still have pressure pulling through it meaning it ain't been released all the way out of the old servers and connections
Another way to understand it do you understand degree value underwater and chill or in heat do you understand the difference how stuff floats in between layers
thật tuyệt vời ❤❤❤ so Amazing video ❤ Một video rất nhiều Kiến thức Và Bổ ích ❤❤ Em ở Việt Nam rất thích Xem video Của Anh ❤ chúc Anh nhiều Sức Khoẻ Và Làm nhiều Video Hay nhé ❤❤ I really like You video so much ❤ thank You for sharing video so amazing ❤ I Hope you Alway Lucky and Happiness
This has such a 00s vibe , had to made then
That's some god dam engineering!
Exited ❤️
Great movie
41:50 I think that chemists concoction was a little heavy on the ratio with fish 😂
I guess you felt angry 😂😂😂😂 I can feel your hunger too that fish is enough to feed on
I LOVE YOU!
Wow 🤩
Amazing structure what humans can build is mind boggling
Very interesting
This video didn't age well, the dam is already crumbling lmao
-999 social credit!
God, you sure love that 3d graphics software at Element 18 eh?
The dam is almost as long as the Golden Gate Bridge.
The Chinese have a bridge longer than that bridge as well.
@@indridcold8433so does the US. It's in New Orleans, LA and it crosses Lake Pontritain.
Damn! 🤗
Here's one way in lightning and thunder they say there's like a 7 mi difference or 7 minute difference between the sound that it makes and the color it shows well in my analogy water is lightning The sound is the spread volume of direction of minerals or growth to pull in different pollings or color alignments farms
But anyways in the distance of your water I consider that a force of lightning
❤ super butiful good morning family ❤️🌹🛡️
"Yeah, I have a question... Is this a 'God Dam'?"
Nice
That's a lot of resources there. I wonder how many countries have giant holes in them, for all of those resources.
They had their own resources sir. China produces 60% of the world's cement.
They are not like many nations that have no domestic production. They have their own resources. Most of what is in your home is likely made in China.
With zero thought to ecosystems, even their own...
@@carlsaganlives6086 yet u wrote ur stupid comment with a device which has resources from china and probably was made there aswell
Now I have to write a project about it
39:23 Even a great engineering like this, without a good management, it will still cause terrible flooding, hilariously.
thats what the fish said when it swam into a wall dam
Mr Mutero Mr Mupondi Mr Nyandoro Legends
18:48 What about all the concrete that will sink to the bottom of the reservoir? Does that just stay there?
where is ITAIPU DAM ? We produce 76.382 GWh in 2020. We are the BIGGEST in Energy Production.
it's in Brazil.
@@j121212100 for sure.
well, 3 gorges is supposed to average 95TWh, compared to 76 for ITAIPU. So ....
In the documentary it says it's twice the size of the itaipu
The fish were not just flapping at the location They were flapping very very far away from location You changed Mother Nature And started global warming with these contraptions These dams 🦫 We’re only supposed to be temporary Our moms and dads and grandparents gave this energy to us gratefully Now we are to upgrade it so our planet can stop dying
A great construction
Didn't mention the Niagara project of the early 20th century.
Man built a dam to please his friends
Dr. Shitlow made an incredible cocktail. How much you think you pay someone to drink that ? 🤔
Desperate people drink garbage like that daily. Granted, they do not last long.
Great facrs; ridiculously overwrought, melodramatic music! Way too 'dark'; wanted the sound off!
The 3 Gorges Dam sits on a 50m wide thick concrete base keyed into the bedrock. The base of the dam wall is 45m thick with probably 500 mm or more concrete cover. The dam is stronger than the mountains around it. 😊 Note that dam outflows are reduced during floods downstream caused by heavy rainfall DOWNSTREAM of the dam to mitigate flooding
No it isn't
@@rooh5825 You obviously are NOT an experienced engineer 😋
@@wulung5943 I know enough about common sense and science to know BULLSHIT when I smell it.
I am as well
The dam is structurally compromised leaving everybody down river in danger😂😂😂
To date there are no dams running multiple banks for turbines why? Well the story you are told is there are issues like turbine surging and dissolved gasses in the flow. This was the case But in Australia RDP Marine has made a turbine system that can be retro fitted
What I'm really interested to know is how was Jean Claud Van Dam was built...
So here's another one and your equipment or in technology that's building all your infrastructure of your machinery as it lays now do you know if you are under seawater or above seawater do you know how to build the mathematical formula to understand that rotation in growth or in losses how to stimulate the layers of movement
d c can do favorable ? blessong ?
DAM!
44:05 OK. Then what will they do to resolve the problem?
How this channel have just 70k subs?
43:21 - 43:58 But this will only shift the sediment that had collected near the dam. What about the sediment that has settled along the length of the reservoir?
KIT CAT!
这个视频好像是30年前拍摄的。
3G is tofu for sure Not sure about the rest All dams need to go But I do prefer dams for energy Seems that all dams need a upgrade and need to use 1/7 the surface area and not block the flow but stay under it Technology has improved Sad it improved the time they completed
38:52 it’s already flying apart and crumbling
#Highlights 💡 The Three Gorges Dam in China is the largest concrete structure on Earth, spanning over two kilometers and standing 60 stories tall. 💡 It took 17 years and 40,000 workers to complete, and it will produce over 20,000 megawatts of power, equivalent to twice the nuclear power stations in Britain combined. 💡 The dam engineering pinnacle owes its success to five landmark dams, each featuring significant technological innovations. 💡 The dam's construction required diverting the massive Yangtze River and relocating over a million people. 💡 To understand its power generation, the text traces back to 19th-century Britain when the world's first hydroelectric dam was developed. 💡 The Three Gorges Dam has 32 generators, producing 5 million times more power than the 1878 Debden Dam. 💡 The Hoover Dam in the USA employed innovative techniques, including cooling with river water, to expedite construction.
The issue is safety of factor of the to withstand environmental disaster for instance an earth quick. What is the safety factor of 3 Gorges Dam?
That make China economic grow so fast. Everywhere have big construction, China company is there.
It was NOT a single light bulb but enough to light several rooms. There was a master switchboard so that all the house could be lit. The swtchboard has totaly open contacts. The whole system would be operational except for the dreaded 'elf and safety'. Rubber gloves please.
Amazing ❤
Feel like watching aliens
Where are Itaipu dam - in Brasil?
❤
Better build basements for dams so if they over flood they don't break.
You forgot Tarbela Dam
Music title at 2:04 and 4:44 please. Thanks
Export the Azure, Chat GPT, Revit, Plant 3D, Civil 3D, Inventor, ENGI file of the Building or Refinery to Excel, prepare Budget 1 and export it to COBRA. Prepare Budget 2 and export it to Microsoft Project. Solve the problems of Overallocated Resources, Planning Problems, prepare the Budget 3 with which the construction of the Dam or the Refinery is going to be quoted.
27:03 the water coming down is the pressure at the bottom when it flows over and the curve is like a sideways bridge this is why there not straight The secret is the over flow🤭🤫
It’s Hoover, not Hover Dam
DAMM!!!!!
The major problem is capital for building big stractures
So the world is thirsty because of Las Vegas 😂
댐이없이연어가상류까지가는물길을지하에반드시만들어
18:28
So they don't use any steel reinforcement
When was this made? 1996?
Has to be.
The dam opened in 2012, so after that
But before 2015, based upon a comment in the video.
3.25-3.33 LOL!
what about Ethiopia dam (abay or Nile dam??5600 mw
dammmmmmmn
Politicians needs to quit stealing the funds
3 gorges dam is falling apart. It is structurally compromised.
