Week02:Disobedient Electronics

“The Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River by the town of Sandouping, in Yiling DistrictYichangHubeiprovince, China. The Three Gorges Dam has been the world's largest power station in terms of installed capacity (22,500 MW) since 2012.[5][6] In 2014, the dam generated 98.8 terawatt-hours (TWh) and had the world record, but was surpassed by the Itaipú Dam, which set the new world record in 2016, producing 103.1 TWh.[7]

Except for the locks, the dam project was completed and fully functional as of July 4, 2012,[8][9] when the last of the main water turbines in the underground plant began production. The ship lift was complete in December 2015.[10] Each main water turbine has a capacity of 700 MW.[11][12] The dam body was completed in 2006. Coupling the dam's 32 main turbines with two smaller generators (50 MW each) to power the plant itself, the total electric generating capacity of the dam is 22,500 MW.[11][13][14]

As well as producing electricity, the dam is intended to increase the Yangtze River's shipping capacity and reduce the potential for floods downstream by providing flood storage space. China regards the project as monumental as well as a success socially and economically,[15] with the design of state-of-the-art large turbines,[16] and a move toward limiting greenhouse gas emissions.[17] However, the dam flooded archaeological and cultural sites, displaced some 1.3 million people, and had caused significant ecological changes including an increased risk of landslides.[18] The dam has been controversial both domestically and abroad.[19]

Though the large size of the reservoir caused huge relocation upstream, it was considered justified by the flood protection it provides for communities downstream.[124] As of June 2008, China relocated 1.24 million residents (ending with Gaoyang in Hubei Province) as 13 cities, 140 towns and 1350 villages either flooded or were partially flooded by the reservoir [A_2-M:CR3-1HP:S-15],[125][126][127] about 1.5% of the province's 60.3 million and Chongqing Municipality's 31.44 million population.[128] About 140,000 residents were relocated to other provinces.[129]

Relocation was completed on July 22, 2008.[126] Some 2007 reports claimed that Chongqing Municipality will encourage an additional four million people to move away from the dam to the main urban area of Chongqing by 2020.[130][131][132] However, the municipal government explained that the relocation is due to urbanization, rather than the dam, and people involved included other areas of the municipality.[133]

Allegedly, funds for relocating 13,000 farmers around Gaoyang disappeared after being sent to the local government, leaving residents without compensation.[134]

For this assignment I planned to a mobilized river-lantern: A propelled tiny ship with LED attachment. After the relocation of Three Gorges Dam. Millions of people have lost their home. Many media reported that people who died after the relocation refused to be buried at the relocated place and wished to be buried at where they have lived. In Chinese tradition there is a popular ritual called river-lantern. People gathered together and make river lantern as a memorial ceremony for their passed family and friends. For this design, the lantern goes against the natural water flow and propels back to where people’s original home was.
