How will the Three Gorges Dam make money?
I heard about the Three Gorges Dam in China being built on the Yangtze river, and people are saying that it will cost up to 100 billion dollard- but that it will pay for itself in the long run. How will this dam make that much money?

Hydroelectricity, I'm guessing. That's what made the Hoover Dam such a great feat of engineering, for sure.

The main economic benefit is certainly hydo-electric power generation. It has an installed capacity of 22.5GW from its 30 main generators, and is already generating an average of 100TWh of electricity per year. At that rate it will pay for itself in about 10 years or 1000TWh generated. Thats assuming the dam doesn't burst first and create possibly the greatest ever man-made disaster. The dam is some 185m high, holding back a reservoir lake some 600km long. Ironically, another intended main economic benefit of the dam is flood protection along the Yangtze River. If it fails, it could cause the worst flood ever, making the 1954 flood seem like a trickle. Other possible benefits are increased shipping capacity along the river, also relying on a ship lift still being built, improved irrigation systems (!) and income from tourism as a new "wonder of the world".
