There is a massive elevator for ships built into the Three Gorges Dam on the Yangtze River in Yichang City, central China’s Hubei Province. The mostly silent CCTV+ footage above shows it in action.

A feat of engineering, it can transport 7 million pounds of ship + water 112.8 meters (370 feet) up or down in just 40 minutes. Costing $37 billion dollars to build, the elevator replaced five stages of locks that transported ships over three hours, but comes at a higher price:

The dam is the world’s biggest hydropower project, but its construction 13 years ago was controversial. It forced the displacement of over a million people and has apparently caused deadly landslides along the river.
