The New Great Wall

The Explore team takes you to the site of the Three Gorges Dam before it was completed and became the largest hydroelectric dam in the world - more than five times the size of the Hoover Dam. The dam's five-step system of locks raise and lower ships by as much as 371 feet, and 25 massive turbines power a city four times the size of Los Angeles. Distributed by TubeMogul.

The largest hidroelectric dam is ITAIPÚ where Brazil and Paraguay meetand still will be for many decades. While Three Gorges dam is phisically larger, it will never have the water flux to reach the megawatts that Itaipú generates. Besides, because of local geological considerations, Three Gorges will have a short useful life of only about 30 years due to high rates of sedimentation.
