Experts give 50 percent of the success of this project. And if it will work, I could produce the same amount of electricity as a small nuclear power plant. Operating principle geothermal power, Iceland makes geothermal energy into electricity in two ways: from the well Steaming temperature 600 F, which is fed directly to the turbine, and a more efficient method, which gives supercritical water from deep wells, making steam that drives a turbine. The natural supply of supercritical water and turning it into electricity, would be like to transition from diesel to jet fuel. To assess the benefits available to natural supercritical water, we say that the majority of power plants and nuclear power plants also produce supercritical water before generate electricity. Power stations produce thermal energy produced by burning coal or radioactive decay of isotopes to the water in a sealed tank turned into a supercritical state.

The process allows water maintain high-energy intermolecular bonds in the liquid state until it flows through the pipes, with almost zero resistance, as a gas. Two and a half miles of underground water heated by magma to 1100 . At this temperature, it usually exist as pairs, but a lot of pressure keeps it liquid. And if the water is released to the surface in the supercritical state will retain almost all its energy. But engineers will have to redesign the existing heat exchangers, so that they can operate with high temperatures and resisted corrosion. Then the power plant running on natural supercritical water could produce up to 500 b megawatts of electricity, along with a small nuclear reactor or power plant at half capacity. But unlike them, geothermal power plants using renewable and virtually no comprehensive source of energy, with zero emissions. Prospects for development of geothermal energy in Iceland now uses its geothermal potential is only 20 percent of the total possible.

If they had exploited all the resources of the island only in the usual way, we could produce 20 gigawatts of electricity per hour per year – as three nuclear reactors. Iceland uses geothermal energy to start from the beginning of the XX century. On the island there are five district heating geothermal power plants with total power capacity of 420 MW, which produce 26.5% of all electricity in the country, and 90 percent of their heating and hot water is heated by geothermal energy. Possible But the problems of such a large project, there are serious problems and risks. At worst, it can release and leakage of water under high pressure, then unrestrained fluid flow will sweep the whole rig, which happened to One of Iceland's projects in 1999, then, because of the failure of valve used to isolate the source in case of ejection, there was an explosion, which left behind a crater 30 meters wide. It is also possible that deep-water containing hydrochloric acid and the liquid for several hours without any problems melt steel. Also, the drill may stumble directly to the magma, or skip supercritical water, then you have to leave this area and drill elsewhere. Iceland established its own project using geothermal energy, which may be an example for countries with similar terrain. Japan and Italy are open about their potential supercritical water, but Iceland is the first country has made a big step in the use of geothermal energy. News of science and technology


The book, with infantile poems, was dedicated its children. Vincius, poet of the love and of deeper sensuality, was perhaps not adjusted to speak to the children, however, when making it, the naivety reencontrou and left to be taken by the playful one, indispensable combination for the success. The Infantile poetry is made of ludicidade, simplicity and rhythm, having made with that the child comes back to its proper world. It is what we observe in a first reading of the poem. The poet uses the Onomatopia (tic-tac) to give to rhythm and sonorous effect to the poem. This repetition throughout the text finishes making of the noise a great trick.

(Tic-tac) it reproduces the next possible sound to the clock, therefore we classify this sound as a pure Onomatopia. This is one of the resources expressive more used in the infantile poetries, therefore they concentrate the melody, the harmony and the rhythm of the phrase, serving to produce this effect special. What it differs a Onomatopia from the Aliterao is that this suggests a sound and the Onomatopia imitates. Still saying of rhythm the author, to mark the compass of the poem, it uses the commas. They serve, in this in case that, to mark the pauses in the text, what it makes in to remember them the hand of the seconds dislocating itself. How much to the lexical choice, we can observe that the author looked for to use words that throughout the text go if relating to the proper heading of the poem, the Clock. For example: time, hour, are slow, day, night. This choice almost always is made propositalmente.

We still observe a sensible fort of opposition how much to the job of the words. We start for the proper Onomatopia (tic-tac). Fonemas /i/ and /a/ if opposes a time that /i/ is closed and /a/ is opened.

Perhaps because it is located in the heart of the Savannah and at the foot of Mount Megaliesberg. West Brom might disagree with that approach. Its main economic engine are the extraction of Platinum mines. In fact Rustenburg is the World’s leading producer of this mineral. The Spanish team already played a match against South Africa in his Royal Bafokeng Stadium during the 2009 FIFA Confederations Cup. Once used for Rugby Union competitions. And it has been renovated for the World Cup. It has expanded its capacity to 3,000 seats, and installed giant screens and more lighting.

Bafokeng is the name of the tribe of the area. Polokwane to 60 km to the South of the Tropic of Capricorn, Polokwane is located in the land of the giant Baobab trees and represents the main economic and cultural center of the Limpopo. Dominated by a tropical climate, it is distinguished by its landscapes, endless meadows and towering mountains. It is surrounded by Botswana, Zimbabwe and Mozambique. Your Makapan cave preserved fossil remains of the stone age. The Peter Mokaba Stadium emulates the silhouette of a Baobab and has been modernised on the occasion of the World Cup.

Nelspruit the perfect location to enjoy a safari. To the northeast of South Africa, on a high plateau of 660 meters above the level of the sea, the city of Nelspruit is It lies a few kilomentros of the National Park of Kruger, the most famous of all Africa. It is also the capital of the province of Mpumalaga, which means place where the sun rises in Siswati, one of the eleven official languages of Africa. The Mbombela stadium is very original. The pillars are shaped of Giraffe and chairs creating a surprising effect stripes. Pretoria is the administrative capital of South Africa and one of the leading cities in academic terms. It has the best African continent universidadesdel. At 50 km away from Johannesburg, Pretoria mixes old and new, and in her embrace contemporary art with historical monuments. Their Loftus Versfeld stadium is one of the oldest in the country. With capacity for 50,000 people, it hosted the Rugby World Cup in 1995. Port Elisabeth surrounded by impressive beaches, and numerous buildings of Victorian architecture, port Elisabeth is an attractive tourist destination. It is named after the wife of Governor Rufan Donkin. Its colonial atmosphere to catch the most nostalgic. In his Stadium Nelson Mandela Bay, on the shores of the North End Lake, will vie for eight parties, including the third and fourth place match. Bloemfontein is the judicial and administrative capital of South Africa, and is located in the heart of the country. It is known as the city of roses due to the beauty of its gardens and parks. The lovers of archaeology visit its National Museum of South Africa, with one of the largest collections of fossils and archaeological finds in the country. The citizens of this region are considered the more keen for South Africa and will be the guarantee of good humor in matches that will be played at the Free State Stadium in Bloemfontein.
