Alternative Fuel

Brazil leaves in the front in alternative fuels - Ambientebrasil - 23/04/06


When if it thinks as they will be the ways of transport future it, then come to the head those images of ships passing through for skies of the urban centers, as the represented ones in the livened up drawings. But the evolution of the transports is far of this, at least short and average the stated periods. The type of energy that goes to move the terrestrial vehicles mainly is the great fidget. To some years, the drivers go to leave to supply its cars with gasoline. Beyond the alcohol, a consolidated alternative technology already, the vehicles will depend on the energies renewed to twirl for the streets and roads. They is esteem that the oil goes to be depleted the 70 or 80 years. Today, the price of the barrel of the oil already scares. These factors, added to the fact to have that if to reduce the ambient pollution, stimulate the studies and research on alternative power plants, as the solar one, the nuclear one, proceeding from biomass or vegetables (that they produce oils). When the situation of the oil to press, Brazil will be one of the few countries that will leave the chaos with advantage. For having a vast territory that can be cultivated, it will be able to create a good one offers of fuels you renewed, as the proceeding ones from the wood and the sugar cane-of-sugar (alcohol). "the solar energy, for the time being, has a cost very raised. The nuclear energy possesss great problems how much to the security. The renewable one and of biomass has great advantages. They will leave in the front the countries with great cultivated areas ", explains the teacher Fernando Tadeu Boçon, of the Department of Engineering Mechanics of the Federal University of the Paraná (UFPR). Another alternative source is the electric energy. Although all to know that the oil one day goes to finish, and this date are each next time, hardly new systems of energy will be implemented soon. For the professor Ramon Sigifredo Cortés Walls, also of the UFPR, still it lacks much investment in the development of new technologies for alternative fuels. "to arrive itself at this, it has that to have investment in research and development. Today, the studies are focados in something less including, very specific. Lack that organism that catches the project and implements. One does not see clearly politics of State for this. But some institutions, as the Petrobras, is worried about this. The Petrobras finances research with biodiesel, already thinking about the future, when it will not have more oil to commercialize ", it thinks. The world starts to think about alternative fuels. Some countries, as United States and Japan, had had interest in knowing as it functions and as a Brazilian technology developed in the decade of 1970 would be implemented, that the oil will be an efficient alternative when to finish. The alcohol, an old one known of the Brazilians, is a biocombustível. "Already we have the technology of production and refining, beyond the well developed engines. When the oil to be more expensive, goes to have that to exist one politics of State to make possible a bigger production, with more plant. Still we produce relatively little in comparison to the potential of the alcohol. When the oil really if to deplete, the alcohol will be a very viable alternative ", tells to the professor Fernando Boçon. In accordance with it, the developed countries can until preparing proper technologies, but they go to be attracted to adopt a ready system, whose viability already is proven, as it is the case of the alcohol.
