tidal energy tidal is the generation of electricity through the use of energy contained in the entry of water bodies due to tides. Two types of tidal energy can be obtained: kinetic energy of current due to tidal energy potential by difference between a height of the tides high and low.Anywhere the surface ocean oscillates between high and low points, called tides, each 12h and 25min. In certain bays and estuaries, as next to Mount Saint - Michel, in the estuary of river Rance, France, or in Sao Luis, Brazil, these tides are quite amplified, and may reach heights of the order of 15 metres. The unbulk water bodies covering two thirds of the planet constitute the largest solar collector imaginable. The tides, caused by the attraction Lunar, also represent a seductive energy source. Together, the temperature of the oceans, the waves and tides could provide much more energy than humanity would be able to spend today or in the future, even if the overall consumption simply fold every ten years. [citation needed] Energy mares is similarly of hydroelectricity.This is a complex hydraulic engineering. Built a dam, a reservoir seacoast. When the tide is high, water fills the tank, passing through the turbine hydraulic type bulbo, and producing electric power. At low tide, the reservoir is flushed and the water tank passes again through the turbine conflicts, producing electrical power. This source type is also used in Japan, France and England. The first plant tidal built in the world for electricity generation was de La Rance, in 1963 and before 1500 in lameiras municipality of Sintra for direct use in moendas.OECD and FAO are questioning biofuelsAccording to the report of the Organisation for economic cooperation and development (OECD) and the United Nations for the food and Agriculture (FAO) on prospects for agriculture world in the next decade, published on Wednesday, 4 July 2007, if a high price for some products, particularly for cereals.Analyzing what has happened so far, the drought in some countries cereal farmers and the reduction of surpluses due to demand Chinese and the reform of the common agricultural policy (Cap) explain the recent spikes in prices of some raw materials. "But, looking to the long-term, structural changes that are occurring will maintain high prices for many agricultural products in the next decade," says the report. What changes are these? "The reduction of surpluses and a decline of export subsidies contributing to these changes, but the most important is the growing use of cereals, sugar, oil and vegoils to produce substitutes for fossil fuels, i.e. ethanol and biodiesel." Which will lead to higher prices of cultures, malignancy.this, drift, which will reflect in the final costs.According to the report of the European Union, the quantity of oil used for biodiesel should increase from the current ten million tonnes to 21 million within ten years. In the United States, ethanol from corn will double by 2016, while in Brazil, the 21 billion litres today produced saltarao for forty - four billion.The report emphasises that, in most countries temperate, ethanol and biodiesel is
not economically viable without public support. Which means that political decisions taken in the short term may modify the scenario described in the study. The introduction of new technologies and the price of oil are two other variables that also contribute to remaining many unknowns about the future of this new market.
other technologies of greater efficiency, as is the case of turbosail, vespicula vertical appropriate to capture the low pressure by passing in rotor thrust protected internally. This type does not risk of collisions of blades with flying (wild animals) and does not interfere in audiovisao. This technology is already a reality that both may be introduced into the marine environment as in land.
Geothermal energy or energy geotermal is the energy obtained from the heat from Earth, more precisely Interior. Because the need to get electricity more clean and in increasing quantities has developed a way to leverage this heat for generating electricity. Today much electricity comes from the burning of fossil fuels, such as oil and coal, methods, these highly.So that we can understand how is seized power from the heat of the Earth must first understand how our planet is set up. The land is formed by large plates, which keeps isolated Interior, in which we find the magma, which is basically rocks melted down. With increasing depth temperature of these rocks growing, however, there are areas of intrusions magmaticas, where the temperature is much larger. These are areas where there is considerable potential for geothermal purposes.HistoryThe first attempt to generate electricity sources geothermal took place in 1904 in larderello in the region of Tuscany, Italy. However, efforts to produce a machine to take advantage of such sources were unsuccessful because the machines used suffered destruction due to presence of chemical substances contained in the steam. Already in 1913, a 250 kW was produced with success and around World War II 100 MW were being produced, but the power plant was destroyed during the war.Around 1970, a field from El in California was 500 MW of electricity. The holding of this field has been dramatic because in 1960 only 12 MW was produced in 1963 and only 25 MW. Mexico, Japan, Philippines, Kenya and Iceland have also expanded the production of electricity through geothermal.In New Zealand the field of gas wairakei, on the island, North, was developed around 1950. In 1964, 192 MW were being produced, but today this field is ending.Portugal account with a modern central geothermal into operation on the island of Sao Miguel, Azores, that in addition to other older, and is being finished third in a new island, the Azores.Geothermal energy sourcesRock dry hotWhen no El, and the conditions are favourable, unable to "stimulate" warming watermark using the heat of the Interior of the Earth. An experiment carried out in Los Alamos, California [1], demonstrated the possibility of implementing this type of power plant. In fertile were punched two wells neighbours, distant 35 metres laterally and 360 m vertically, so that they achieve a layer of rock hot. In a datawell is injected water, it warms rock and leaves on the other tergirgi, where there is a power plant geothermically installed. The experiment Los Alamos is only a pilot project and does not generate energy for commercial use. Duration of this field can be is 10 years.Wet hot rockYou can also drill a well before it a "boiler" course formed a heated heat. From there, electricity is generated as in all other cases.Dry steamIn cases rarissimos can be found what scientists call source "dry steam", in which the pressure is high enough to move the turbines power plant with exceptional strength, and source efficient generation of electricity. Are found sources steam dry larderello, Italy and in Cerro Prieto in
Mexico.Advantages and disadvantagesThe power plant geothermically of nesjavellir, near ingvellir, Iceland.Approximately all workflows geothermal water contains dissolved gases, and these gases are sent to plant energy generation along with water vapour. One way or another these gases have just going to the atmosphere. The discharge of both water vapour and CO2 are not serious significance in appropriate scale of geothermal power stations.Furthermore, the smell unpleasant nature irreverent, and the properties harmful acid sulfidrico (H2S) are causes of concern. In cases where the concentration of acid sulfidrico (H2S) is relatively low, the smell of gas cause nausea. In higher concentrations can cause severe health problems and even death by suffocation.It is also important that appropriate treatment water coming from inside the Earth, which invariably contains ores harmful to health. Should not occur simply your dump in rivers, so that it does not undermine local fauna.When a large amount of fluid aqueous is withdrawn from the Earth, there is always a chance to occur on the surface subsidence. The most drastic example of a problem in plant geothermically is wairakei, New Zealand [2] the level of surface sank 14 metres between 1950 and 1997 and is deformando at a rate of 0, 22 metre per year, after achieving a rate of 48 metres per year in the mid - 1970s. It is believed that the problem may be mitigated with re - injection water.There is always noise that afligiria the entire population contiguous site power plant, for drilling the well is necessary to use machine similar to that used in drilling of oil wells.
biomass from the point of view of power generation, the term biomass covers derivatives recent living organisms used as fuel or for their production. The point of view of ecology, biomass is the total amount of living matter sire ecosystem or a population animal or vegetable. The two concepts are interconnected, although they are different.In the definition of biomass for energy generation are traditional fossil fuels, although these are also derived from plant life (coal) or animal oil and gas), but they are the result of various transformations that require millions of years to occur. Biomass can be considered a renewable natural resource, while the fossil fuels not renew the short term.Biomass is used in production of energy from processes like the burning of organic material produced and accumulated in an ecosystem, but not all primary production is to increase biomass plant of the ecosystem. Part of this energy accumulated is employed by ecosystem for its own maintenance. Its advantages are the low - cost is renewable, allows the process of waste and that other forms of energy such as that obtained from fossil fuels.The burning of biomass causes the release of carbon dioxide in the atmosphere, but as this compound had been previously absorbed by plants leading to fuel, the balance sheet of CO2 emissions is null.//Use of biomass as fuelOne of the first use of biomass by humans to acquire energy began with the use of fire as a source of heat and light. The field of natural resource brought to man the possibility of exploitation of minerals, ores and metals, selecting new period anthropological. Wood similarly was for a long period of time the main energy source, with it the cooking, the steel industry and the ceramics were undertaken. Oils multiple sources were used to a lesser extent. The great leap of biomass is the advent of firewood in steel, in the industrial revolution.In the years understood the 19th century, with servicesmicrofilm technology steam, biomass had primary role also for mechanical energy with applications in sectors in industry and transport. Despite the beginning of the exploitation of fossil fuels, such as coal and oil fuels continued playing important role energy, particularly in tropical countries. In Brazil, was used on a large scale, reaching the mark 40% of primary energy production, however, for the environment as a value that is not a reason for celebrations, after all, deforestation of forests Brazilian has increased in recent years.During the then collapse of oil supplies that occurred during the 1970s, this became evident by the wide use of articles from biomass as alcohol, woodgas, biogas and vegoils in internal combustion engines. Nevertheless, the internal combustion engines were first tested with derived from biomass, being virtually unanimous statement that fossil fuels only obtained priority by economics, such as supply and demand, never by technical issues of adequacy.To obtain the most varied sources of energy, biomass can be used in a manner broadly, directly or indirectly. The lowest percentage of air pollution and global located, the stability of the carbon cycle and the largest employment
methodology for the manufacture of car alcohol reached levels of excellence. The problems faced in the 1990s of desabastecimento of alcohol that generated the fall in car alcohol are no longer a threat to the consumer thanks to recent offer of bicombustiveis.Recently, the program of biodiesel is being deployed to put vegetable oil as complementary to diesel oil. First the mixture will be up to 2% of derived from biomass in diesel with an increase in gradativo until the percentage of 20% within ten years.The Brazilian experiment is not limited only to transport, electricity has been promoted with the injection of energy as a result of Barra alcohol and sugar, generated from the incineration of Marc and straw of cane sugar. Other waste as rice straw or sawdust wood also maintain some termoeletricas by the country.Environmental impacts and cautionDespite expediency referred, the use of biomass large-scale also requires certain care that must be remembered, in the 1980 and 1990 development furious drawing of alcohol in our country has made this clear. Joint ventures for the use of biomass widely may have environmental impacts. The result may be destruction of fauna and flora with extinction of certain species, soil contamination and mananciais of water by use of fertilizers and other means of defence handled inappropriately. Therefore, respect for biodiversity and environmental concern must govern any intention of use of biomass.
etc.) and the type of agriculture practised (intensive agriculture, organic farming etc.).Biofuels resulting from the recycling of waste oils can be considered that there is a positive environmental balance, because these oils could be pollutants or have a use less efficient.As biofuels produced from agricultural products, to make a environmental balance must be taken into account the impact of fertilizers and pesticides, water consumption, which can be very important for certain plant species, and the impact on biodiversity when huge areas of culture replace areas very rich in species (tropical forests and other hot spots as the Mediterranean area). The balance sheet CO2 biofuels is not neutral, taking into account the energy necessary for their production, even if the plants to check the carbon in the atmosphere: we must take into account the energy needed for the production of fertilizers, for the transportation of agricultural tractors, for irrigation, for the storage and transport. The row of pure vegetable oil has a better balance sheet of biodiesel.OECD and FAO are questioning biofuelsAccording to the report of the Organisation for economic cooperation and development (OECD) and the United Nations for the food and Agriculture (FAO) on prospects for agriculture world in the next decade, published on Wednesday, 4 July 2007, if a high price for some products, particularly for cereals.Analyzing what has happened so far, the drought in some countries cereal farmers and the reduction of surpluses due to demand Chinese and the reform of the common agricultural policy (Cap) explain the recent spikes in prices of some raw materials.

um cartaz, mas como as criancas ainda nao sabem ler,achei que seria interessante colocar o desenho sobre os nomes, entao pedi aosalunos para escolherem um personagem para desenhar e colocamos os desenhossobre os nomes, desta forma, quando necessario, poderiam recorrer aos desenhos Aposterem terminado os desenhos, colamos no painel da parede, um lugar de facilvisualizacao, todos puderam olhar os desenhos uns dos outros. Este momento serve tambem para contarhistoria e em alguns momentos as historias sao contadas com auxilio de livros erecontadas pelas criancas que querem recontar, em outros momentos as historiassao inventadas na hora e com participacao dos alunos. Neste dia resolvemosinventar uma historia de arrepiar, cada crianca criava uma parte da historiautilizando um personagem do mundo da imaginacao. Apos concluirem as atividades,as criancas tem liberdade para pegar um livro ou um brinquedo e sentar notapete para nao atrapalhar os colegas que ainda nao terminaram. Apreferencia da turma e por atividades de recorte e pintura, gostam e permanecembastante concentrados confeccionando pulseiras e colares de micangas.
