National Geographic: Big,Bigger,Biggest:Dam S02E08


mother On the waters of the Yangtze river, China rises the biggest concrete structure on the planet The three gorges dam is over two kilometers long and sixty storeys tall It has taken 40,000 workers over 17 years to build When it fully comes online, this one dam would produce over 20,000 MW of power twice as much as all the nuclear stations in Britain put together It is the pinnacle of dam engineereing The three gorges dam owes its success to five landmark dams The three gorges dam is the biggest hydroelectric project in the world This dam used 28 million cubic meters of concrete Maybe one way to look at it is to say

  1. I wonder if they took into consideration the erosion in the turbine tunnels over time. I know Niagra falls erodes at one foot per year and has been as high as 3 feet. I don't know the rate at which concrete erodes compared to stone but it must be something the engineers took into consideration?

  2. I'd be surprised if the Chinese government actually relocated those people. I'd imagine they just kicked them out of their homes and left them.

  3. Consider the massive amount of energy that's used to build these dams then consider the damage caused to our Earth, finally think of zero point energy which is the energy that exists in the vacuum of space or as it's known, the quantum vacuum which is all around us. They have known that this energy exists, where it is and how to extract it cleanly and safely. Why has this technology been suppressed for decades ? I smell a rat.

  4. TOO MANY ADS…..I already pay for internet….why do I have to watch more ads ? I never buy what you are selling on purpose.

  5. If liberals were seriously worried about CO2 destroying the Earth in 10 years, they would allow more hydroelectric power plants to be built. The USA could build several more on the Colorado River similar to Boulder Dam. We could build paddle wheel generators on the sides of rivers without building a dam or blocking rivers. My sister has a creek running through her property. I could build a paddle wheel generator on her creek to power her entire house 24/7. Local environmental regulations prevent me from doing this.
    The northeast has so many rivers and water running, we could power the entire Northeast US using hydroelectric power. Where I live on the Grand River in Michigan, they have dams all along the river to prevent flooding, but they generate zero power. The coal plant has a dam to keep the water level at a steady level next to the dam, but it generates no power. If they put turbines and generators on these dams they could all be generating power. Instead the water if flowing over them and down the spillway next to the dam producing zero electricity.
    Corporations would be happy to build hydroelectric dams where they can sell the electricity with zero fuel. Environmental regulations in the USA prevent them from building more dams. China is building dams, India is building dams, many countries are building dams. The USA no longer builds new dams because of environmental regulations prevent this. If the left actually believed the world was about to end from CO2, they would choose the lesser evil and allow hydroelectric dams to be built. It won't matter if a fish has to go up a fish ramp to spawn, if the world ended from CO2.

  6. Could this be the awesome Construction that temporarily stopped the Earth's rotation ?

    Dam !

  7. When it officially became fully functional on July 4, 2012, China hailed
    the Three Gorges Dam, the world’s largest power station with 22,500
    megawatts of installed capacity as a resounding success. They pointed to
    it's modern, highly efficient turbines, it's ability to increase
    shipping capacity along the Yangtze River and the fact that it could
    help to prevent downstream flooding by freeing up flood storage space.
    Not only all of this, but it was a move towards limiting greenhouse gas
    emissions. Sounds great, but, there are two sides to every story and the
    negative consequences of this monumental project, which cost the
    country the equivalent of around 25 billion U.S. dollars have been
    described by many as catastrophic both in its human and environmental
    impacts. Over one million people were displaced and the dam flooded
    historically significant archeological and cultural sites. Entire
    ecosystems were permanently altered with rare plant and animal life
    being pushed to the brink of extinction. Experts warned that the
    increased pressure such a massive structure would create on the
    surrounding land would trigger massive landslides and an increased risk
    of earthquakes, and their eerie predictions seem to be coming true.

  8. I love how they went back to explain the first dam as if there was something critical we needed to know about basic dams rofl

  9. Ya think you could cram a few more ads in here??.. Jeeeez, you’ve made this unwatchable…

  10. Who ever notice 2:06 the exact rectangle on the front shield of that motorcyclist… What a coincidence

  11. They chose a technical British chap who can't pronounce 'water' for a documentary on controlling water 😀
