TheBelo Monte Dam is one of the most controversial projects in the world. The $17 billion hydro-electric dam will, when constructed, generate enough energy for over 23 million homes. However, its creation will see the flooding of huge portions of the Amazon basin, displacing indigenous tribes and putting 500 sq km of rainforest underwater. The project has been met with fierce resistance over the past few years, but this week Brazil’s environmental agency backed its construction, crushing the hopes of indigenous groups and environmentalists.

The agency,Ibama, said the Belo Monte dam on the Xingu River had been subjected to “robust analysis” of its impact on the environment. The government concucred saying that the dam was vital to meet the country’s ever-growing energy needs. Ibama also issued the penultimate licence that the Norte Energia consortium, the group behind the project, needs to build the dam.
Construction work is expected to begin in January and will see the displacement of tens of thousands of local tribes people. It is expected that the dam’s construction will intensify clashes between the indigenous rainforest communities and the government.
The 11,000-megawatt dam will be the third biggest in the world after the Three Gorges in China and Itaipu. Despite being planned 30 years ago, it has taken a long time to get the green light. Critics of the 6km (3.7-mile) dam believe as well as making 50,000 people homeless, 500 sq km (190 sq miles) of land will be flooded.

Floating solar power systems are wonderful ideas for Brazil. And it’s very important to maintain effectively same direction and position on the water for floating solar plants. Because directional change of solar panels reduces electricity production. So floating solar plants also need the directional control mooring systems for their parked positions. Azimuth and position change of floating solar plants caused by wind, waves and external forces. Restoring Force Strengthened Mooring System for floating solar plants has been created in South Korea. This Mooring System generates Restoring Force immediately when floating solar plants are being rotated or moved on the water. In addition, you have to reduce vibration to install floating solar plants. Because, it can make micro-cracks to floating solar panels and the durability problem of floating solar plants. The risk of power loss in PV modules due to micro cracks is increasing. Vibrations caused by wind, waves and external forces. New Type Floating Body Stabilizer has been created in South Korea. The Floating Body Stabilizers generate drag force immediately when floating solar plants are being rolled, pitched and yawed on the water. Recently, Restoring Force Strengthened Mooring Systems and Floating Body Stabilizers have been used for floating solar plants in South Korea. You can see them in Ochang Dam natural reservoir, South Korea. I N I WORLD
"In a very eerie sense, the entire electrical power industry (as approved by the scientific community) worldwide is a giant though unintentional scam, at least since 1957 and the discovery and experimental proof of broken symmetry." - Tom Bearden, Ph.D.
idirex - the question here is another nuclear vs coal vs hydroelectric plant. People in Brazil/China need electricity same as you do - why do you want to deny them this right!?
I've read somewhere that it is the silt deposits that help replenish Shanghai. With the silt and sediments backed behind the dam, the city will suffer from erosion and sink like Venice. The city rests on a massive sedimentary plain. The "arriving silt—so long as it does arrive—strengthens the bed on which Shanghai is built. Since sediment deposits at low areas naturally, the deposits are responsible for land building. 80 percent of the area is experiencing erosion. The lack of silt deposited in the peninsula could result in erosion and sinking of coastal areas.
the problem here is the flood that will be caused by the dam . Those are delicate ecosystems . They have the right to develop but this seems a bit too costly ( economically and environmentally )
the problem here is the flooded area and the delicate ecosystem. ambient vs development , what do you choose ?
Sediment behind the dam is only bad for storage, but it does not prevent the operation of the electric generators. I.e. even if the lake behind the dam gets completely full of sediment, the plant will still be able to produce maximum electricity when fed with running water!
For someone who called electricity the opiate of the masses. You seem to have swung full circle. China's Three Gorges will be useless in just a few decades anyway, the silt deposits are vast that sedimentation projections are not agreed upon, and the other is that the dam sits on a seismic fault. At current levels, 80% of the land in the area is experiencing erosion, depositing about 40 million tons of sediment into the Yangtze annually. And arguments abound that the dam was built poorly. The Amazon deposits more sediments than any river in the world so much so the waters turn the ocean nearby brown.
I love hydroelectric. It is clean and constantly renews itself. But I have to wonder if the that river water is too silty for a dam. Sometimes you have to break a few eggs to make scrambled eggs. In this case, some people will need to move so that the country as a whole can progress forward without the dangers of nuclear.
