Automotive need for gas vs. Hybrid vs. corn Assignment

Automotive need for gas vs. Hybrid vs. corn - Assignment Example D. Anderson & J. Anderson, 2010). Moreover, the use of fossil fuels has increased environmental dangers, thereby fueling global warming. Burning gallons of fossil fuels are increasing the amount of the greenhouse gases, thereby accelerating the global warming. Additionally, the greenhouse gases have subjected humanity to ill health and diverse environmental conditions that have affected the world’s economy. Numerous challenges have been brought about by fossil fuel; therefore, scientists have been searching for an alternative environmental friendly source of energy. Some scientists have suggested the use of hydrogen gas an alternative source of fuel. However, the doubt in the safety of hydrogen gas has slowed down its exploitation and subsequent use as an alternative source of fuel. Additionally, others have suggested the exploitation and use of the natural sources of energy including sunlight and wind. The exploitation of these natural sources of energy may not be quite relia ble due to the inconveniences and unreliable biodiversity and ecosystem. Nonetheless, the scientists in the renewable energy industries across the United States have settled in the use of hybrid biofuel (ethanol) and technology as the alternative to deal with the fossil fuels. Therefore, the scientists have arrived at the use of bountiful corn as a source of fuel for the hybrid transportation technologies. In United States, corn is used to produce ethanol, which is an alcohol. There are numerous ways of making the fuel grade ethanol. The most common process follows the dry mill method where the corn is grinded into powder and mixed with water in the presence of enzyme (Dalton, Hoyle, & Watts, 2011). The mixture is heated at high temperatures after which it is liquefied. The enzyme helps in breaking down grain compounds. The mixture is then taken under a subsequent liquefaction process. The liquid mash is poised, and other enzyme that converts starch in the mixture into sugar is adde d. The additional enzyme helps in fermenting the compound into alcohol. At this stage, yeast is often added to start up the fermentation process where sugars are broken down into ethanol and carbon dioxide. Ethanol is then extracted from the products mixture. The obtained ethanol gas is often mixed with a small quantity of gasoline to make the biofuel, ethanol undrinkable. Module 2: The History of Early Solutions The effects of the fossil fuels have led to numerous problems including global warming and affecting numerous vehicle parts. These problems marked the first intents of scientists to search for alternative fuels that would reduce the production of the greenhouse gases into the Earth’s atmosphere (C. D. Anderson & J. Anderson, 2010). The first countries to initiate the use of ethanol fuel were Brazil and United States. From these countries, the production and use of both biofuel and hybrid technologies did spread to other nations and continents. In the United States, t he United States Department of Agriculture (DOA) and the United States Department of Energy (DOE) are the organizations that are partly funding the production of ethanol from corn and other hybrid technologies. Since the introduction of the ethanol gas or fuel, numerous economic sectors and the environment factors have registered some positive impacts. Notably, the use of the gas dramatically reduced the dependency of America on imported fuel. Moreover, the ethanol fuel consumers have undoubtedly benefited from reduced prices of fuel

Documentary Review - Essay Example As expounded in the documentary, it is evident that the overdependence on one person as the overseer of all processes in the production of bottled water paves way for the occurrence of errors in the bottled water industry. In connection with this, it is evident that the plastic used in bottling water is made out of materials that leak chemicals into the water. Thus, with such leakage of chemicals as well as errors achieved in the process of manufacturing water affect the health of human beings. Disposition of the used bottles is also one of the contributing factors for pollution in the world. Lots of bottles are everywhere; that is, on land and in water bodies. Such bottles hamper with the ecological system, as a result, lead to the death of other living organisms such as marine fishes. Additionally, it is evident that a lot of resources have been wasted in the name of bottling water. The money used in purchasing the materials for the bottles, the manufacturing process of the plastic bottles, transportation of water from one region to another, and the chemicals included in the water cost the production industry a lot of money. A significant amount of money is also used in managing the mess created by the end use of the bottles. Thus, it is advisable for the industries associated with the production of bottled water to stop wasting resources and advocate consumption of natural
