Great Wall and now great wheel?? Three Gorges Dam


China is really standing out, first the great wall, and now the great wheel??
Higher than both the London Eye (73m shorter) and the Singapore Flyer (43m shorter), the Beijing Great Wheel will tower 208 metres (682 ft) when finished in 2009.
The Beijing version will carry 1920 passengers at a time, 40 to each of 48 compartments, able to carry 40 people in a capsul, compared with the Eye, which can carry 25 in each pod (from The Age).
There is a site, http://www.greatwheel.com/.
Price per ticket would be around 100 yuan (if not mistaken), but soon to be finalized.

Damn this dam is HUGE


Another structure that would soon be one of the world's greatest; Three Gorges Dam. "The Three Gorges Dam is a Chinese hydoelectric river dam which spans the Yangtze River in Sandouping, Yichang, Hubei, China . The total electric generating capacity of the dam will reach 22,500 MW and claims the title to being the largest hydro-electric power station in the world by capacity when it is completed. Several generators still have to be installed, and the dam is not expected to become fully operational until about 2011. As with many dams, there is a debate over the costs and benefits of the Three Gorges Dam. Although there are economic benefits such as flood control and hydroelectric power, there are also concerns about the future of over 4 million people who will be displaced by the rising waters, in addition to concerns over the loss of many valuable archaeological and cultural sites, as well as the effects on the environment." Text from Wikipedia.

"This pair of images shows the dam in partial completion in July 2000 and again in May 2006. The Yangtze River flows from upper left toward upper right in the images. In 2000, construction along each riverbank had occurred, but sediment-filled water still flowed freely through a narrow channel near the river’s south bank (bottom left). A smaller passage closer to the north bank of the river, where the water appears calmer, is likely a system of temporary locks that allowed for boat passage. A second dam bypass appears to be under construction about 1 kilometer to the north." source from Earth Observatory .
