The document discusses 5 large dams around the world: Tucurui Dam in Brazil, Guri Dam in Venezuela, Xiluodu Dam in China, Itaipu Dam on the Brazil/Paraguay border, and Three Gorges Dam in China. Three Gorges Dam is described as the world's largest power station by installed capacity at 22,500MW. It has 32 main turbines and cost $22.5 billion to construct. The dam stores water that slightly increases the length of the Earth's day and reduces its speed.

10. 1. THREE GORGES DAM
LOCATION:-
CHINA
CONSTRUCTED ON:-
YANGTZE RIVER,
STARTED IN DEC 14, 1994.
OPENED IN TEAR 2008.
LENGTH & HIGHT OF DAM;-
OVERALL LENGTH :- 2.335 KM
HEIGHT :- 181 M (594FT))

12. ABOUT THREE GORGES DAM
o Its has been the worlds largest largest power station in terms of installed capacity
22,500mw.
o It consist of 32 main turbines.
o The cost of the construction was 22.5 billion USD.
o The dam reduces the coal consumption by 31 million tonnes/year, avoiding 100 million
tonnes of green house gas emission.
o In 2010 nasa scientists calculated that shift of water mass stored by the dam would
increases the length of the earth increases 0.8 inches flate on the poles.
o And also it redues the speed of earth of 0.006 micro seconds every day.
