China is building one of the most ambitious infrastructure projects ever attempted — a $167 billion hydropower project deep inside the Himalayas.
Instead of a conventional dam wall, the project is expected to use massive tunnels and underground power stations to harness the extraordinary elevation drop of the Yarlung Tsangpo River.
When completed, the project is expected to generate around 300 billion kilowatt-hours of electricity every year, potentially producing roughly three times the power of China's Three Gorges Dam.
But the story isn't just about engineering.
The Yarlung Tsangpo crosses into India, where it becomes the Brahmaputra, and eventually flows into Bangladesh. With millions of people depending on this river for agriculture, fisheries, and water, China's project has raised major questions about water security, environmental impact, and the future balance of power in Asia.
In this documentary, we explore:
• Why China chose one of the most extreme locations on Earth
• How the underground hydropower system is expected to work
• Why the project could cost around $167 billion
• How it compares with the Three Gorges Dam
• Why India and Bangladesh are watching closely
• The environmental and geological risks
• And why this could become one of the most consequential infrastructure projects of the 21st century
This isn't just a dam. It's a massive experiment in engineering, energy, and geopolitical power.
Follo for more documentaries about the megaprojects, technology, infrastructure, and strategies quietly reshaping the world.
