The Hydrogen Fuel Economy essays

The Hydrogen Fuel Economy essays This article talks about how the hydrogen economy will be coming. There are a lot of obstacles that they must surpass to form a hydrogen economy. In the year 2003, President George W. Bush announced a 1.7 billion research program to develop a vehicle that would make the air cleaner and use less oil. Toyota came to the U.S with two of them. The first one was a sedan called the hybrid. The hybrid is a gasoline-fueled internal-combustion engine supplemented by a battery-powered electric motor. The hybrid got approximately fifty miles to the gallon. The other vehicle was an SUV, which drove its electric motor with hydrogen fuel cells. Now the next question would be which vehicle out of these two would be the better one. This question is a very important question because it can have a big impact on the amount of money being spent for the research. Robert Wimmer, a research manager, says that both vehicles are about the same. The hybrid can be responsible for more carbon dioxide emission, and also a variety of other pollutants according to the Department of Energy. In another aspect, the hybrid is excellent because it already exists as a commercial product and can already cut pollution presently. Hydrogen fuel cells have two main attractions. First, they do not make any pollution during usage. Secondly, hydrogen can come from many sources. Pure hydrogen does not exist on earth. The good thing about hydrogen is that it can be used for other things like powering homes. Researchers are trying to find ways to turn things into hydrogen, but the processes they come up with are either unaffordable or unavailable on a commercial scale. They can make hydrogen from natural gas, but that would be a waste of natural gas because they can use natural gas itself to produce electricity. One thing that they should be working on is hydrocracking and hydrotreating. The U.S could save three million barrels of oil a day that way. Hydrocracking a...

Interpretations of Heart of Darkness Essays - Joseph Conrad

Interpretations of Heart of Darkness Essays - Joseph Conrad Interpretations of Heart of Darkness In Joseph Conrad's Heart of Darkness, there is a great interpretation of the feelings of the characters and uncertainties of the Congo. Although Africa, nor the Congo are ever really referred to, the Thames river is mentioned as support. This intricate story reveals much symbolism due to Conrad's theme based on the lies and good and evil, which interact together in every man. Today, of course, the situation has changed. Most literate people know that by probing into the heart of the jungle Conrad was trying to convey an impression about the heart of man, and his tale is universally read as one of the first symbolic masterpieces of English prose (Graver,28). In any event, this story recognizes primarily on Marlow, its narrator, not about Kurtz or the brutality of Belgian officials. Conrad wrote a brief statement of how he felt the reader should interpret this work: "My task which I am trying to achieve is, by the power of the written word, to make you hear, to make you feel-it is above all, to make you see.(Conrad 1897) Knowing that Conrad was a novelist who lived in his work, writing about the experiences were as if he were writing about himself. "Every novel contains an element of autobiography-and this can hardly be denied, since the creator can only explain himself in his creations."(Kimbrough,158) The story is written as seen through Marlow's eyes. Marlow is a follower of the sea. His voyage up the Congo is his first experience in freshwater navigation. He is used as a tool, so to speak, in order for Conrad to enter the story and tell it out of his own philosophical mind. He longs to see Kurtz, in the hope's of appreciating all that Kurtz finds endearing in the African jungle. Marlow does not get the opportunity to see Kurtz until he is so disease-stricken he looks more like death than a person. There are no good looks or health. In the story Marlow remarks that Kurtz resembles "an animated image of death carved out of old ivory." Like Marlow, Kurtz is seen as an honorable man to many admirers; but he is also a thief, murderer, raider, persecutor, and above all he allows himself to be worshipped as a god. Both men had good intentions to seek, yet Kurtz seemed a "universally genius" lacking basic integrity or a sense of responsibility (Roberts,43). In the end they form one symbolic unity. Marlow and Kurtz are the light and dark selves of a single person. Meaning each one is what the other might have been. Every person Marlow meets on his venture contributes something to the plot as well as the overall symbolism of the story. Kurtz is the violent devil Marlow describes at the story's beginning. It was his ability to control men through fear and adoration that led Marlow to signify this. Throughout the story Conrad builds an unhealthy darkness that never allows the reader to forget the focus of the story. At every turn he sees evil lurking within the land. Every image reflects a dreary, blank one. The deadly Congo snakes to link itself with the sea and all other rivers of darkness and light, with the tributaries and source of man's being on earth (Dean,189). The setting of these adventurous and moral quests is the great jungle, in which most of the story takes place. As a symbol the forest encloses all, and in the heart of the African journey Marlow enters the dark cavern of his won heart. It even becomes an image of a vast catacomb of evil, in which Kurtz dies, but from which Marlow emerges spiritually reborn. The manager, in charge of three stations in the jungle, feels Kurtz poses a threat to his own position. Marlow sees how the manager is deliberately trying to delay any help or supplies to Kurtz. He hopes he will die of neglect. This is where the inciting moment of the story lies. Should the company in Belgium find out the truth a bout Kurtz's success in an ivory procurer, they would undoubtedly elevate him to the position of manager. The manager's insidious and pretending nature opposes all truth (Roberts,42). This story
