Mega Dams - Hydroelectric Evolution - Big Bigger Biggest

Ғылым және технология

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.

    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.

    #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.
