Automobile in Future

What could be the option for fuel?

Alcohol -  One of the alternative fuels for the future

 

Alcohol fuels such as ethanol is presented as the vanguard, the future of clean alternative fuel to gasoline or diesel. Alcohol is a renewable resource because it can be fermented or chemically extracted from almost any substance containing carbohydrates (sugars and starches). The use of alcohol as fuel for vehicles that could contribute greatly to the independence of the oil in the very near future, but the green is, as an alternative to petroleum fuels?

Henry Ford alcohol for the first time a motor vehicle, and Ford is alcohol as the primary fuel for vehicles and in 1925, claiming that the New York Times that "the fuel of the future will be from the fruit or apple ... weeds, sawdust - almost anything, "he said. "There is fuel in every bit of vegetable matter that can be fermented. There is not enough alcohol in one year, the yield per hectare of potatoes to drive the machinery necessary to cultivate the fields for a hundred of years. " It is often discredited by their own opinions and political associations, no one can honestly say that Ford has been nothing less than a visionary in the field of automotive technology. A farmer and supporter of the agricultural industry in the United States, Ford made its first car in plastic, hemp and plant-based ethanol fuel. It is anticipated the growth of the automotive industry, is compatible with the agricultural industry. Therefore, if we have known about this alternative fuel for more than a century, why have we not been used?

This vision has been largely eliminated by a high pressure of the oil industry, including a smear campaign against Ford, claiming that his plan would be rich farmers at the expense of consumption. Some historians and theorists credit Rockefeller, the billionaire, oil tycoon, mainly with funding from the movement ban to eliminate potential competition in the fuel alcohol. Until recently, falsely low price of gasoline rose from the environmental impact of most consumers, but as we are faced with the staggering effects of global warming, our collective conscience calls us to seek alternatives. The first internal combustion engines, such as type A, are designed to run on alcohol or gas, and small, inexpensive changes can be made to allow vehicles that run on alcohol. In fact, more than two million cars in Brazil have been modified to run on alcohol, which is not surprising that Brazil has an important place in the industry and the ethanol distilled from cane sugar.

The United States also launched an industry of mass production of ethanol using corn as raw material. Crops specifically for ethanol production, however, have generated much debate about the feasibility of this practice. The main arguments are: large areas of deforested land and destroyed the natural habitat to make way for farms to sugar cane or corn, thus negating any advantage in regard to global warming and food shortages in the world can be exacerbated by land used to produce fuel. Both problems can be solved by the use of alternatives to "raw materials" for ethanol and the creation of numerous alternatives has been proposed. As Henry Ford said, "almost nothing" can be used for the fermentation of ethanol, including agricultural waste and food products. Some of the most interesting alternatives to rice straw, which is burned in the fields (the release of huge quantities of greenhouse gases) and human waste, which spend billions of dollars in fossil fuels and process of generating electricity. Imagine, then, that we can create a process of carbon dioxide to produce fuel alcohol. How to clean fuel, and what are its advantages and disadvantages compared to petrol or diesel?

The famous Indianapolis 500 is used as fuel methanol necessary official since the 1960s, there is a variable mixture of chemicals such as gasoline, gives more power to the engines properly, and burns cooler than gasoline. Now, the common use of the engine technology, the alcohol has less energy per unit volume, which offers fewer miles per gallon. Therefore, alcohol fuel in May and offer the same travel distance as gasoline or diesel. One of the biggest advantages to the use of alcohol is the elimination of harmful compounds and tetraethyl lead, benzene, toluene, sulfur, and many others. The high "octane" rating of alcohol, not its resistance to premature detonation, eliminates the problem of engine "knock" (which was originally the creation of leaded gasoline). Alcohol is also safer than gasoline because of its low volatility, which means it is less likely to heat or ignition sparks. Sounds great, right? But at the time of combustion, when used in a motor vehicle, such as emissions of this fuel alternative to the battery? Alcohol is actually a very clean fuel, it emits up to 95% less carbon monoxide and provides a great reduction or elimination of volatile chemicals and poisons. The total reduction in emissions of greenhouse gases may be as high as 75% when using the test in mind.
