Green megastructures: The world’s largest solar bridge

 Solar bridge 

World’s Largest Solar Bridge Crosses The River Thames in London
The reliance of the world on solar energy is increasing, let apart other renewable sources (presently, sunlight is the most common renewable energy that is currently being used). This has become almost compulsory as the excessive use of conventional energy sources has lead to global warming, dwindling sources and deposits of fossil fuels and an ever toughening energy crunch. Solar energy has found its application in almost all kinds of products. There are solar phones, solar laptops, solar refrigerators, solar energy powered cars and now we have a station which would feed itself by the power harnessed by a solar bridge. Let’s have a look at the world’s largest solar bridge.
The mega structure
Bridges and stations are one of the most crucial and business generating parts of urban infrastructures. Unfortunately, they are also among the prime consumers of fuel and probably places, which see gushes of energy being blown into the air regularly.

Today there is flamboyant pressure on countries to reduce their greenhouse gas emissions and also energy consumption. So the natural focus would be places like this, better not to talk about automobiles (personally, I believe there is no auto company left in the world which is not crunching its minds into presenting green things on the roads. Roads, bridges and stations now wait to face the same destiny). Well, London is all set to become the role model in this aspect for it will house the world’s largest solar bridge.

Come 2012, and the city will have a brand new station or rather a renovated station that completely resembles a brand new one at Blackfriars across the river Thames. The station promises to be powered by the sun’s energy. The station at Blackfriars was constructed way back in 1884 and is long overdue for a makeover. The project in hand is potentially huge and will demand an equally huge expenditure of £5.5 billion. It is being totally accredited to Network rails and has been appropriately named the Thameslink project. Now, this is a great move when 2012 Olympics are just on the cards. The city will view a huge addition to its population and a surge in its energy consumption. The number of daily commuters would drastically increase and hence the energy requirement would enhance by leaps.

There are 100 bridges, six public ferries and 20 tunnels that go over the river. However, the Blackfriars station will stand out as it will be the only one to be powered by solar panels. When the project is complete the station be adorned by better features and facilities. Longer trains, increased rail traffic, greater accessibility to rail routes will be some of them. As a toasting example, almost 24 trains will trace the route from Bedford to Brighton via London in an hour.
What makes it mega?
The company backing this project is Solar Century. As for the introductions to this name, Solar Century is an important name in the solar energy panorama that is expanding at a head spinning rate. SANYO Electric Co. Ltd, of the Panasonic flag-ship, will also be involved in this Project as it will produce high efficiency solar modules for the bridge.

The solar powered bridge when complete will generate a whopping 9,00,000 kwh of electric energy. The whole module goes somewhat like this – there would be 6,000 square metres of expanse between the Blackfrairs station and the Victorian Bridge which is to be covered entirely by solar panels. On completion, the bridge would be capable enough to support 50% energy requirements of the station, even when it buzzes with activity the most. The requirement to elongate the station’s deck would not be much, only a staggering statistic of 14,000 tons of new material.

Eco credentials
Coming to the most important part, the eco-friendliness of the bridge. Well, the most obvious thing is that the bridge will produce green energy and hence contribute towards a much strived for ‘lower carbon footprint’. The expected reduction in carbon emission lies in the scale of 511 tons.
The bridge has been overlaid by 4,400 solar panels. Besides, the project would also include setting up of rain water harvesting system and solar pipes in the station to add to the green aspect.

Solar energy: the world's greatest projects.

Today, in Erenovable we bring you a special report where we met some major solar energy projects that are currently being built. From United States to the desert of the Sahara and India, 5 solar thermal and photovoltaic solar energy projects that will provide a good part of the renewable energy in the future.

  
1. ivanpah Solar electric generating system (ISEGS), in the desert of Mojave (United States). It's a solar plant solar thermal with 173.000 heliostats each of two mirrors. Its installed capacity is 392 MW and is expected to be operational in 2013. Part of the investment is carried forward by Google.
2. Farm plots in the Sahara desert. In the world's largest desert many European countries see a future for its production of solar energy, whose electricity would be transmitted through high tension lines, which would require a huge investment. However, the result would be as - or more-impressive: about 100 GW of electricity by 2050.
3. The Solar park in the world in South Africa, is being planned for that from 2012 will bring to 5 GW of electricity, the equivalent of 10% approximately of consumption in the country. The plant will combine solar panels and mirrors, and will be in the region of North Cape.

4. blythe Solar power Project and beacon Solar energy Projectin California (United States). These two solar plants are developing bend the installed capacity of the country. The first of them will be functioning in six years with a 1 GWproduction, and the second will be opened in three years with a capacity of 250 MW.
5. Solar plant of Mithapur, (India). Located in the region of Gujarat, this new venture of Tata power will be the largest photovoltaic solar Park in the India and expected that its production reached the 50 MW. The venture is more significtivo part of a national project to achieve a total production of 20 GW of total installed capacity of solar power by 2020.

The world's largest park Fotovoltaico

Obtained through solar photovoltaic energy requires a large amount of cells according to the amount of energy that seeks to obtain, which leads to the realization of complete installations of these panels that occupy few yards and even hectares of land.

A clear example of this is the recently opened Fotovoltaico Park which was opened in Ontario (Canada) very close to the border with the State of Michigan (United States) which is already running, and estimate, you will be able to produce until 80 Mega Watts of electricity.

Entrepreneurship has been carried out by Enbridge Energy companies and the First Solar firm, and has become the largest in the world, shifting to a second place located in Olmedilla (Spain) which currently has a capacity to generate up to 60 Mega Watts of electricity photovoltaic Park.

This Park will have a production capacity of up to 120,000 MWh per year, which is estimated will reach to meet the energy needs of at least 12,800 homes Canadians.

South Africa created the world's largest solar Park

Use of Solar energy is one of the most widely accepted Renewable energy in the world, where increasing emphasis is placed more to the creation of solar parks, covering large areas of land forms and capable of supplying entire cities without any problem with a long-term investment.

In the last hours have been announced intentions to South Africa becoming one of the major powers in the field of solar energy, as it provides for the creation of the World's largest Solar Park, with a plant that according to schedule, will be able to provide up to 5 GW of electricity.

Investment would cost some 18.42 trillions of pounds (about 21 billion euros turnover) and will require the combination of solar technologies latest together to solar panels and mirrors of large dimensions, which are located in the region of North Cape.

With this plant not only seeks to meet up to 10% of the energy requirements of the country, but also significantly reduce the CO2 emissions, since now more than 90% of the electricity is obtained through energy plants that work based on the burning of coal.

Is expected that the initial phase of this project is completed by the end of 2012, where you can get up to 1 GW of power electric.

The world

We talked a lot about using renewable energy to care for our planet, but really do we know of the Earth? The answer may be quite varied, covering according to different concepts and forms of analyzing it, so try to be brief and provide an answer to this simple question.

This article will seek to provide a geological analysis of what The world, defining initially to geology as science which performs an analysis of the exterior and interior of the Earth form, the nature of the materials that comprise and their training, in addition to changes or alterations that has undergone since its origin, and placement of them today.

Among its main characteristics we highlight 6371 km RADIUS and its temperature with a gradient of 1 ° C for every 33 meters, with a temperature in the Centre of the estimated land between 2200 ° c 4400
With regards to its conformation, enumerate various "layers" differentiable characteristics:

Litósfera: 5 kilometres of basalt and 65 kilometers of Rock Granítica Pirósfera: 1500 to 3000 kilometers, rocks rich in iron and aluminum silicate, at a temperature of 2000 ° C Barísfera: rocks of nickel and iron, comprising 3000 km, 4000 ° C temperature

These layers float on the core (molten rock) is located downtown, and perform various movements that give rise to the following phenomena:

Magmatismo:Blend until cooling magma vulcanismo: the molten rock (called Ígnea) rises by fissures in the form of magma) or volcanoes (lava) maremoto: violent shocks to the sea level terremoto: vibrations on the rocks Tectonismo: movement of the solid parts of the Earth, which gives rise to displacement (fault) or deformations (faulting) metamorfismo: alteration suffered by rocks, generating recristalizaciones combined effect of heat and pressure.






In turn, these movements can be classified in Epirogénicos and Orogénicos.
Epirogénicos:Rising or sinking continents, or large parts thereof, whose vertical forces fractured rocks Orogénicos: Craps at a given time, give rise to the formation of mountains, volcanic and seismic and generate a horizontal compression with movements ondulamiento and folding activity generation systems.
