The AP reports that China has flipped the switch on the first of 12 turbine generators on the right side of the ginormous Three Gorges Dam, with it apparently already pumping electricity to the national power grid after a 72-hour test run. The dam itself, as you’re no doubt aware, is the world’s biggest hydropower project evar, totaling up to some $22.5 billion. In addition to giving it something to brag about, China is hoping that the dam will let it cut its dependence on coal, as well as control flooding on the Yangtze river. This latest development follows the activation of 14 turbines on the left bank of the dam, which began operating in September of 2005.
