Powerful Presentations - Essay Example For most scholars, that is introducing data, as a rule to a group of people that is about as educated regarding the matter as we seem to be. (Anthony 45-57) For introductions, that is a deadly blend. Verifiable data introduced at an elevated level of specialized mastery doesn't convince, however may really estrange the peruser. For a great many years, individuals have attempted to make sense of the most ideal approach to convince others to get things done. We realize that influence has been the subject of genuine investigation since the times of old style Greece. Plato stressed over the rhapsodes' capacity to speak to residents' feelings and convince them to do things that were not in the best of enthusiasm of the city or themselves. What's more, Aristotle thought of one of the incredible treatises on influence. (Rasmussen 23-36) Among the Romans the capacity to convince was viewed as a sign of capable citizenship. Since World War II, scientists have endeavored to distinguish the components of influence. Why They have some functional intentions: improving promoting and advertising efforts, propelling crowds, affecting the electorate, bracing customers and voters against purposeful publicity, understanding the elements of programming, and-yes-composing better introductions. From this hypothesis and research, four components have reliably been an imperative piece of almost every hypothesis of influence: the message, the collector, the channel, and the source. (Daley 79-83) Giving them some thought will give us a more profound comprehension of the procedure of influence. Message The effect of your message depends to some extent on whether the recipient is open to it in the first place. On the off chance that the proof or rationale in a specific enticing message is in accordance with the crowd's fundamental qualities, convictions, or inclinations, the recipient is bound to acknowledge it and change their perspectives appropriately. In the event that the proof contradicts the recipient's fundamental convictions, influence is far less inclined to happen. In this way, the manner in which you outline your message as to your crowd's inclinations is basic. That may appear to be roundabout: You can convince individuals to acknowledge just the things they as of now acknowledge or to do the things they as of now need to do. Yet, that is not exactly what's happening here. (Holcombe 112-24) There is a contrast between a conviction and a disposition. Somebody may give a RFP for new gear since the individual in question accepts that creation effectiveness can be improved by utilizing increasingly present day innovation. On the off chance that you can put together your introduction with respect to a similar conviction and, at that point exhibit how your hardware will present work sparing improvements, the collector's disposition toward you as the most reasonable merchant will change in a positive manner. Notwithstanding, in the event that you convey a canned introduction, one that accentuates the roughness and toughness of your machines, rather than their effect on creation productivity, you will be not be tending to the customer's essential conviction. (Anthony 45-57) accordingly, you may not convince the person in question to pick you. This is the basic issue in submitting standard introductions. Since clients fluctuate generally in their convictions and qualities, utilizing a similar book for everyone ensures that a huge level of them will discover your message unimportant or unconvincing.

Unavoidable Destiny Flannery O’Connor’s Southern Adaptation of Oedipus Rex - Literature Essay Samples

Flannery O’Connor’s Wise Blood is a powerfully unsettling novel concerning a lost man in the grotesque, dark world of the American South. Published in 1949, Wise Blood’s protagonist Hazel Motes serves as a reflection of the power of mythology that continues to assert itself in O’Connor’s text. Throughout the course of the novel, Hazel Motes’s character aids Wise Blood in becoming a southern adaptation of one of classical literature’s most memorable stories that of Oedipus the King. Although some aspects of the novel are strictly evident of the impact of twentieth century southern culture on one’s religious identity, Wise Blood effectively mirrors the plight of destiny that is equally present Sophocless Theban Cycle, written and performed more than two thousand years prior. Understanding Oedipus’s oblivion and subsequent tragic fulfillment of prophecy is immensely helpful in the analysis of Hazel Motes as a man struggling with faith in the darkness and distortion of religion in the American South. From the onset of the account the reader receives concerning Hazel Motes’ birth and the circumstances of his childhood, one can quickly draw parallels between the start of his own life and that of tragic Oedipus. The circumstances surrounding Oedipus’s birth are quite unfortunate, and although Hazel’s aren’t nearly as dramatic, there is apparent still a degree of prophecy that both characters will be encouraged to avoid. Hazel’s prophecy seems to stem from the position of his grandfather in society as a preacher delivering God’s message from his car, the tangible symbol of commercial mobility. Hazel’s formative years concern his knowing that he was destined to become a preacher like his grandfather when he comes of age, yet the start of the novel concerns his outright declarations against being a preacher, no matter how much closely he may resemble one. Hazel Motes is not a man of many words, but the words he does speak often begin wi th the words â€Å"I am† or â€Å"I am not†. These statements of his definition of identity are attempts to reject his association with Christianity, but no matter how hard he tries to escape it, it is impossible to shake. Hazel Motes takes to his Essex and the Church Without Christ like Oedipus takes to the crown of Thebes; these tangible symbols of power or newfound identity may seem like the ultimate usurpation of destiny, but they are sadly not as infallible as the characters would like to believe. Much like the grotesque, working class southerners of O’Connor’s fiction that struggle with the conflation of the engagement of sin, the desire to cling to something for a sense of truth in the world, and false confession, the protagonists are ultimately clinging to a â€Å"truth† that will fail them. Like Oedipus, Hazel Motes sets out into a world in the hopes that his transience and outspokenness against destiny will alter it in his favor. However, each man will ultimately recognize that destiny cannot be avoided and that prophecy will be fulfilled, regardless of their attempts at rebuttal. The transience of Oedipus via his desire to escape his destiny revealed by prophecy is reflected in Hazel’s mobility away from his Protestant upbringing and towards his quest for nihilism. Both characters’ efforts to escape and elude destiny simply bring them closer and closer towards its fulfillment, whether they realize it in the moment or not. Oedipus abandons Corinth in fear of the prophecy of killing his father and marrying his mother, only to unknowingly murder his father during this period of transition. What is so interesting about the connection of both stories is that both men result to killing a single man of significance during their travels of escape. The quest that both characters undertake result in the murder of a man who resembles them in some way, whether they realize the extent of the resemblance or not. Hazel violently runs over his â€Å"twin prophet† as an exercise of his power as a man who is trying to devalue the concept of sin, and Oedip us kills his own father over an essentially meaningless issue concerning chariot traffic. The men commit these murders without contemplating the consequences, failing to realize that the deaths will set into motion the later mutilation of self and the continuation of the fulfillment of prophecy. If Hazel so strongly believes that there is no such thing as sin, he fails at his ability to cope with his actions. Oedipus, likewise, must also come to terms with the truth, no matter how uncomfortable or unbelievable it may seem. Sin cannot simply be washed away and forgotten, as O’Connor’s grotesque southerners are portrayed to believe. Both men will be forced to come to terms with the true gravity of their situations, and, as a result, they will become physically blinded by everything they tried so hard to avoid coming to terms with. They can’t simply confess their sin and continue to live their lives in the same sinful manner, believing that they are redeemed as Oâ €™Connor’s southerners believe. The most obvious correlation between the tragedy of Oedipus and that of Hazel Motes is their willingness to engage in physical torture as a result of the fulfillment of their prophecies. The mutilation of self, while it screams psychological distress, is an effort towards redemption, something that both characters never knew they would need or want to possess. The trope of sight is embedded so heavily into both stories, and the blind advisor figures of both Tiresias and Asa Hawkes foreshadow that the tragic heroes will ultimately result in becoming blind in order to finally â€Å"see† the truth. Hazel’s clouded vision throughout the course of the novel is peculiar in the way that it prevents him from consciously observing the details of the world that surrounds him. His inability to pay attention to what is going on around him is too much like Oedipus’ ignoring of the all of the obvious hints he receives about the prophecy being fulfilled. The character of Haze l Motes can be read as an essentially modern refiguring of Oedipus, the king of Thebes that consciously tries, but unfortunately fails, to avoid the fulfillment of his destiny. O’Connor’s reimagining of this character in Wise Blood, however, emphasizes the effects of the conflation of secular and religious culture in the south, where racism, commercialism, and various mediums of sinful entertainment are beginning to run rampant. One’s sense of identity is often tied towards their material possessions, as made evident in Hazel’s statement that â€Å"Nobody with a good car needs to be justified† (O’Connor, 72). The â€Å"sinsational† advertisements that plague the towns, seducing pedestrians into attending secular spectacles continue to distract southerners from traditionally stressed Christian values. The question becomes: how can one struggling with faith function in a world where they are constantly tempted by the sin of secularism? Hazel Motes fails to see the reality of the evil that surrounds him. Protestant sin and confession seems ridiculous and redundant, especially in the ways that the working class Protestants portrayed in the novel are quick to commit sin because they feel that a simple confession will rid them of their wrong doing. Of course Hazel Motes is confused by Christianity. He is too blind to see the value of legitimate redemption and the personal security of living a truly devout religious lifestyle. The society that he was born into and forced to navigate upon his return home from the war continues to ruin his ability to believe in the true grace of God because of the prevalence of fraudulent Christians. Blinding himself from the seduction of the ever increasing secular world is the only way for Hazel to come to terms with the concepts of faith, sin, and redemption. He would simply continue to be unable to understand the true meaning of redemption if he continued to physically observe the fr audulence that surrounds him on a daily basis. Reading Wise Blood in the image of Oedipus Rex is difficult not to do if the reader has been exposed to the work of Sophocles. This association creates an interesting access point through which the reader can magnify the plight of Hazel Motes, increasing both his tragic nature and the reader’s understanding of reasoning behind his torture of self. While the temptations of the American South may be unique to its geography and time period, the southern adaptation of this classical tale still emphasizes that one’s mental constrictions can bring about their downfall. For Oedipus, his tragic flaw is his undeniable hubris and inability to listen to those around him, but for Hazel, his is much less obvious. Hazel’s flaw lies in his oblivion, his preoccupations with nihilism and the rejection of his identity, and his inability to see the evil in the environment that surrounds him.

Ice Breakers for the First Day of Elementary School

The first few minutes of class, kicking off a new school year can be awkward and nerve-wracking for both you and your new students. You dont yet know these students well, nor do they know you, and they may not even know each other yet. Breaking the ice and getting the conversation going so everyone can get to know each other is an important thing to do.   Check out these popular  Ice Breaker activities that you can use with your elementary school students when school opens. The activities are fun and easy for students. Best of all, they elevate the mood and help thaw out the first day of school jitters. 1. Human Scavenger Hunt To prepare, pick about 30-40 interesting characteristics and experiences and list them on a worksheet with a little-underlined space next to each item. Next, have the students roam around the classroom asking each other to sign on the lines that relate to them. For example, some of your lines might be, Went out of the country this summer or Has braces or Likes pickles. So, if a student went to Turkey this summer, they can sign that line on other peoples worksheets. Depending on the size of your class, it may be OK for each student to sign two of any other persons blank spaces. The goal is to fill up your worksheet with signatures for each and every category. This may look like organized chaos, but the students will typically stay on task and have fun with this one. Alternatively, this activity can be put into the format of a Bingo board, rather than a list. 2. Two Truths and a Lie At their desks, ask your students to write down three sentences about their lives (or their summer vacations). Two of the sentences should be true and one should be a lie. For example, your statements might be: This summer I went to Alaska.I have 5 little brothers.My favorite food is brussels sprouts. Next, have your class sit in a circle. Each person gets a chance to share their three sentences. Then the rest of the class takes turns guessing which one is the lie. Obviously, the more realistic your lie (or mundane your truths), the harder time people will have figuring out the truth. 3. Same and Different Organize your class into small groups of approximately 4 or 5. Give each group two pieces of paper and a pencil. On the first sheet of paper, the students write Same or Shared at the top and then proceed to find qualities that are shared by the group as a whole. Make sure to point out that these should not be silly or trite qualities, such as We all have toes. On the second paper, label it Different or Unique and give the students time to determine some aspects that are unique to only one member of their group. Then, set aside time for each group to share and present their findings. Not only is this a great activity for getting to know each other, but it also emphasizes how the class has shared commonalities as well as unique differences that make up an interesting and completely human whole. 4. Trivia Card Shuffle First, come up with a predetermined set of questions about your students. Write them on the board for all to see. These questions can be about anything, ranging from What is your favorite food? to What did you do this summer? Give each student an index card numbered 1-5 (or however many questions you are asking) and have them write their answers to the questions on it, in order. You should also fill out a card about yourself. After a few minutes, collect the cards and redistribute them to the students, making sure no one gets their own card. From here, there are two ways that you can finish out this Ice Breaker. The first option is to have the students get up and mingle as they chat and try to figure out who wrote the cards they are holding. The second method is to begin the sharing process by modeling for the students how to use the card to introduce a classmate. 5. Sentence Circles Split your students into groups of 5. Give each group a piece of sentence strip paper and a pencil. On your signal, the first person in the group writes one word on the strip and then passes it to the left. The second person then writes the second word of the burgeoning sentence. The writing continues in this pattern around the circle with no talking. When the sentences are complete, the students share their creations with the class. Do this a few times and have them notice how their collective sentences improve each time around.

The relation between a unit and other units (inner relations between units). No unit can be used independently; it serves as an element in the system of other units. This kind of meaning is called syntactic. Formal relation of units to one another is studied by syntactics (or syntax). Only inner (syntactic) relations between linguistic units served the basis for linguistic analysis while the reference of words to the objective reality and language users were actually not considered Syntactic units can go into 3 types of syntactic relations. SR1 can be observed on the phrase, sentence and text levels. Coordination may be symmetric and asymmetric. Symmetric coordination is characterized by complete interchangeability of its elements – pens and pencils. Asymmetric coordination occurs when the position of elements is fixed: ladies and gentlemen. Forms of connection within SR1 may be copulative (you and me), disjunctive (you or me), adversative (strict but just) and causative-consecutive (sentence and text level only).

Credibility Statement: Studies of Global Warming have gained my interest within the past few years due to the extreme heat and natural disasters around the world. IV. Preview: Today I will be talking about the affect of Global Warming driving our animals in to extinction, a rise in the amount of extreme weather disasters around the world, and the change it will cause to the earth and our family’s future. Transition: Let’s begin with my first point – Body I. Main point: How the effects of Global Warming will drive our animals nto extinction, increase the amount of extreme weather disasters, and the change it will cause to our future. A. â€Å"Global Warming Fast Facts† (National Geographic News, June 2007) 1. Average temperatures have climbed 1.4 degrees Fahrenheit around the world since 1880. 2. Arctic ice is rapidly disappearing, and the region may have its first completely ice-free summer by 2040 or earlier. 3. Wildfires,  heat waves, and  strong tropical storms, are also attributed in part to climate change. 4. In July of 2006 heat waves contributed to the deaths of at least 225 people in North America. 5. Warmer temperatures could increase the probability of drought 6. Warmer temperatures increase the energy of the climatic system and can lead to heavier rainfall in some areas. Signpost and transition: Now that you know what effects Global Warming is having on our weather I will be telling you about how it will affect our animals. II. Main Point: The reason for animal extinction is because our animals can’t adapt to rising climate changes. A. These are some of the facts (nrdc. org, 2008) 1. The predicted range of climate change by 2050 will place 15 to 35 percent of the 1,103 species studied at risk of extinction. 2. Increasing global temperatures are expected to disrupt ecosystems, pushing to extinction those species that cannot adapt. 3. Some polar bears are drowning because they have to swim longer distances to reach ice floes. B. Global Warming will drive our animals into extinction Signpost and transition: The final aspect of Global Warming that I will be talking about is the effect it will have on our future. III. Main Point: Our future is in for a drastic change from what we call normal today. A. Rising sea levels could flood many South Seas islands and swamp large parts of Southeast Asia. B. Researchers predict the earth’s temperature may rise to an additional 5 or up to a drastic 12 degrees Fahrenheit. C. Warmer water in the oceans pumps more energy into tropical storms, making them stronger and potentially more destructive. D. Greater evaporation, particularly during summer and fall, could exacerbate drought conditions and increase the risk of wildfires. Transition: Let’s review what we learned today about Global Warming Conclusion: I. Summarize: The world is in store for a major change. Rising temperatures are having major effects in several different areas and aspects of the world. An increase in more powerful tropical storms, wildfires, and rising water levels will change the world that we live in today. A. We should familiarize ourselves with what the effects of our everyday lives are having on our future. B. Are you contributing to the destruction of our future? C. Life as you know it will never be the same II. Close with impact: No matter how much you try to ignore Global Warming the earth as we know it is in a lot of trouble. Without change we are heading down a road of destruction. References NRDC. (2008, December 10) Wild Life.

Harrison Company Case Study Example | Topics and Well Written Essays - 5000 words

Harrison Company - Case Study Example It is important to highlight that the company faces multiple social and ethical issues. The issues are being identified and discussed in the table below: Issue Description about the issue Association in terms of outsourcing with a Honduran company that engages unethical manufacturing practices in its units The issue of unethical manufacturing practices engaged by a Honduran company came into focus when one of the ex employees of the company spread the word in the media that the company share a buyer relationship with the Honduran company that follows slave like working conditions for its employees. The ex employee brought the accusation that Harrison Company engage in buying inexpensive clothing from the Honduran company. Lack of whistle blowing policy It can be assumed that the claim by the ex employee that he was fired because he tried to generate awareness among the top management about the unethical practices of the Honduran company as true. The reason behind considering this inc ident as a true one is because there is no possible documentation of this incident, which further reveals that the top management did not want to keep a record of this incident and preferred to keep it hidden from the employee view. The lack of a whistle policy within the organization and the option of protecting an employee who engages in whistle blowing activity for the welfare of the organization perceived as a very serious ethical issue. Lack of ability to form a union The company’s focus on restricting the freedom of the employees to form a union has to be considered seriously from the ethical angles. The inability to form a union by the company’s employees will keep themselves vulnerable to the whims and fancies of the top managements. The top management has the ability to make certain changes in regards to pay as well as working conditions which may not be on the employees’ collective favour. The lack of ability to form a union by the employees will lead to the loss of the power of the employees to engage in collective bargaining, which has the potential to develop a sustainable and healthy work environment within the company. Significant amount of donation to the charity It has been identified that the company makes a huge amount of contribution to the favourite charity of the previous president, which is located very close to the company headquarters. Since the company is facing financial difficulties in the current times, the large contributions to the charity become an indirect social issue. The reason this can be a social issue for the company is because the company is focusing on generating profits by relying on part time workers, thereby reducing the chances of full time employment for the potential employees. Significant amount of contribution to the various communities It has also been found that the company makes a considerable amount of contribution to various community specific endeavours. Since the company is facing fin ancial difficulties in the current times, the large contributions to the community endeavours become an indirect social issue. The reason this can be a social issue for the company is because the company is focusing on generating profits by relying on part time workers, thereby reducing the chances of full time employment for the potential employees. Talking in regards to a factor of environmental stability, the issue of unethical slave like manufacturing conditions within the Honduran company needs to be taken into focus. This particular issue has been considered since it has the ability to trigger a threatening situation in terms of political as well as social environment stability in the host country. It needs to be considered that the continued engagement and association of Harrison Company with the Honduran company, which already has developed a notorious reputation for slave type manufacturing conditions, will have a strong negative impact on the company’

Crimes Research Paper Example | Topics and Well Written Essays - 1500 words

Crimes - Research Paper Example Murder is considered the most serious violent crime and its punishment is life prison, long prison life or capital punishment (death). Different states have different laws in relation to murder but the common division is manslaughter and murder. Murder is where the killer thought and intended to kill without a justifiable reason. In this case, the killer does not have a reasonable explanation to commit the crime. Murder can also take place under the felony-murder rule. Where one in the course of committing a felony such as robbery kills somebody else, he is charged with murder although there was no initial plan or premeditation. In this case, the person acted in a dangerous way and his behavior led to the death of somebody else. The difference between manslaughter and murder therefore is in the fact that there is no premeditation in manslaughter. Manslaughter is further divided into voluntary and involuntary categories. Voluntary manslaughter means that the intention to kill is there but it comes up suddenly due to intense emotions but it was not planned. In this case, there is no cooling off period between the action that brought the aggravation and the killing. There is no intention to kill but it happens due to carelessness or negligence. Voluntary manslaughter is not as serious as murder but it results to prison time. The only killing where the killer is released from responsibility is killing in self defense (Storing, 1981). Crimes against Property Crimes against property are those which involve theft without any force or threat directed towards a person. These include burglary, motor vehicle theft, larceny-theft and arson. Burglary is where one enters into somebody else's property such as a building to steal something. Lacenny-theft does not involve entry into a person's property but it is the unlawful taking of property. Embezzlement involves the changing something that was lawfully acquired to conduct unlawful activities. In embezzlement, the property must have come to the suspect's possession through a fiduciary relationship. It involves an element of breach of trust. It is necessary to prove breach of trust by showing that the property in question was handled in a manner that is not consisted with the trust arrangement. The required mental state for one to be accused of embezzlement is that there must have had been an intent to defraud and convert the property in question. Other types of crimes against property include fa lse pretenses and receiving stolen property. In false pretenses, a person is deceived to give up his rightful ownership or possession of property with an intention of converting the property to personal use. Possession or concealing, receiving and buying of stolen property also constitute of a crime against property. Under the crimes against property, extortion is the only intent crime. Another word for extortion is blackmail. It involves the taking of

A SMALL PLACE JAMAICAN KINCAID Essay Example | Topics and Well Written Essays - 1000 words

A SMALL PLACE JAMAICAN KINCAID - Essay Example However, as I kept on reading, I figured that Jamaican Kincaid is about a journey of a tourist, who comes far away from his every day world to have a good time. It shows the ignorance we use as bliss in order to go through an ordinary life. Starting from the customs at the airport, writer Annie John has tried to show the difference the tourist is likely to notice once he/she arrives in Antigua. The cab ride, which starts with the driver quoting a high price than the one he would charge the local people. The writer shows here that people in these countries, especially cab drivers feel that their best chance of earning easy money is to quote a high price to a western tourist as the drivers would feel that these tourists would not mind spending these amounts of money since they do not have any idea about the regular charge. The ride to the hotel might seem dangerous if narrated, with nearly no traffic rules being followed and the condition of the roads giving you the feeling that you are in Disney Land and taking a ride in a roller-coaster. However, the writer says that the tourist would not feel much of a difference as the cab drivers in New York are also from these parts of the world and would have a similar style of dr iving. The writer talks about the possible confusion of the tourist when he sees expensive cars Made in Japan, he must wonder how can these people afford it, do these people have equally expensive houses to go with this car? The writer posing this question gets the chance to take a dig at the government of Antigua which owns two major car dealerships in Antigua. The government hence makes car/auto loans easier for consumers while home loans remain stringent. Describing the god awful look of the hospitals and the quality of the doctors, Annie John makes the reader think about the helpless condition of people in Antigua. As the writer said, the ministers can take a

Changing Roles of Human Resource Management Essay -- Human Resource Ma

Human Resource profession has faced numerous challenges in the past, which has forced HR managers to try and implement various strategies in the work environment all in the aim of survival and prosperity of the business. The National Institute of Personnel Management (NIPM) in India recently organized the 37th annual conference of HRs to discuss the various challenges in the work place and ways of mitigating them. It was unanimously concluded that HR managers needed to revise its roles and create new roles for organizations. The new roles would help in repairing the structural foundation of a company by being proactive and innovative instead of following monotonous routine schedules. Despite the challenges and solutions to the problems that have been suggested, the question still remains, who shall take care of HR managers if they themselves are caretakers and contribute to strengthening the backbone of a company? Culcuttta et al, 2007, suggests that strategies to be implemented should be in tandem with the current trends in globalization, technology, diversity, e-business, and ethics. Furthermore, the need to take care of HR managers goes hand in hand with the saying that â€Å"No company is sick, nor the commodity, but the performing and non performing managers are the ones who matter the most in carrying forward a business successfully.† In the last twenty years there has been a gradual transition in style and substance from personnel management to HR management, and more recently to international HR management. Briscoe et al, (2008, p. 22) believe that the personnel management role lacked strategic relevance because it was mainly an administrative type role whereas the modern concept of HR is much more strategic in scope.

Green Building Technology Essay

1. Introduction Would there be a technology that can benefit nature and human beings at the same time? Conventional belief over the use of technology is that nature is sacrificed and used up for the sake of human beings. However, technology is not simply about efficiency anymore, and its associated grounds are expanding. Concern over environment is one of the most prominent ones, and ‘Green building technology’ falls under it. Green building technology aims to create environmentally responsible buildings or housings throughout its life span, while using the resources available efficiently. It involves the whole process of building certain structure, covering the processes of design, construction, operation, maintenance, renovation and deconstruction (EPA). In short, it is construction technology that tries to optimize environmental sustainability and efficiency while not giving up the necessary qualities of living spaces. Idea of Green building arose as OPEC oil embargo occurred in year 1973 with an Initial goal of reducing its fossil fuel usage. This being a motive, further researches was done by different groups and green building came into housing trend (Marble Institute) After that, there had been increased attention and development of green building technology. People are more interested in looking for environmentally friendly housings and many governments are promoting it through different kinds of green construction standards. Yet, is this technology really giving us substantial benefit in our daily lives? What kind of benefits, in specific, is it providing? What would be the processes of achieving such impacts? Even though this technology does not have a long history, it is already causing changes in reducing energy and resource usages; economic and social benefits are in rise too. Green building has substantial positive effect in both environment and economy, with potential for better outcomes in the future. This can be supported by numerous facts and application of technology. Specific applications of controlling energy usage leads to outright reducing of resources used in construction, which in bigger ground, leads to overall change of human society. 2. Functions in Resource Conservation 2.1 Background The need to conserve natural resources arose from several natural changes in climate. First major change was the global increase of temperature, which also caused devastating natural disasters. (Figure 1) For example, this diagram from NASA’s investigation implies that until the point of 1990s, at least there were below-zero global temperature anomaly. But it has exceeded the point of 0 degrees Celsius since then, reaching higher points. This caused problems like shifting natural characteristics for some countries (i.e. gaining more tropical climate, while the area doesn’t fall under tropical area) and extreme weathers like heat waves leading to hundreds of casualties (IPCC). Stanford researchers predicts summers will keep getting hotter for the next 20 years (Rust,2011) Additional problems of high energy dependencies and its consequences are not negligible too. Oil prices have doubled since 10 years ago with annual increase of 25% between 2004 and 2008 (Bauer, 2010). For countries who import their energy resources, reducing the energy usage and saving money is a big concern. High dependency in energy usage often causes crisis in some special crisis situations. It could be financial, political, or literally natural disaster. While so, housing alone takes up major portion of total energy usage. According to United States’ Environmental Protection Agency (EPA), it accounted for 38.9 percent of total U.S. energy consumption in 2005. In year 2006 it took 72 percent of total U.S. electricity consumption and this number will rise to 75% by 2025. So it can be seen how change in managing housings can lead to positive changes (EPA). Green building technology tackles against these problems with many different technologies, adopting them appropriately for each aspects of energy conservation. While so, 2 examples that directly fight against specific aspects are brought up here. 2.2 Heat Control Firstly, it has been said that the heating and cooling process of a household heavily uses electricity and causes substantial carbon emission. Following are statistics stated by EPA: †¢ The average household spends at least $2,000 a year on energy bills — over half of which goes to heating and cooling. †¢ Out of the total energy consumption in an average household, 50% goes to space heating, 27% to run appliances, 19% to heat water and 4% goes to air conditioning. The numbers are self-explanatory; heating and cooling alone is a big part of whole energy consumption. Temperature control technology for green building enables reducing such consumption and carbon emission. During summer the sun light directly enters through houses through windows or hits the surfaces of outer building and heats up the whole construction. Four factors affect heat accumulation in a home: solar heat gain, internal heat gain, air leakage, and temperature difference. To solve these problems, approaches such as using shades, changing color of outer building, change of roof structure, reducing internal heat generating sources (ex. Electronic equipment), and better use of spaces for air ventilation are used. Today’s buildings also use machine controlled ventilation system or, manual adjustment of ventilation openings to control the heat (Bauer, 2010). On the other hand, during winter it is important to keep and gain every possible heat. A simple method like building the houses facing towards south or optimizing use of sunlight would be the most well-known methods. Additionally, methods of ‘loading up’ the heat into the building are also used, which is using methods like using atria or double faà §ade- dual dimensioned surfaces like windows or wall surfaces- which can support the heat insulation by 20% (Bauer, 2010). As a particular example, window films are proven to be effective in solar radiation cut, reducing the heat level entering a house. The benefit of windows films is clear; it reflects the sun radiation that causes heat and let the room keep cool with less efforts, in terms of both cost and energy usage. This means less air conditioning is used and less energy is consumed. It is proposed by Solar Gard ®, that â€Å"Not only do Solar Gard’s architectural solar control window films help cut energy expenditures by up to 30%, its Environmental Product Declaration (EPD) scientifically proves that Solar Gard and Panorama ® solar control window films have a net positive environmental impact worldwide (Solar Gard). These are specific effects of window film proposed by them; 1. One square meter of a low-e wood window, the type with the smallest carbon footprint, has a carbon cost of 253 kilograms. The carbon cost of Solar Gard window film is less than one kilogram per square meter. 2. Solar Gard window film saves 1001 times more GHG emissions from entering the atmosphere than is used and/or created during its manufacture. 3. Solar Gard window film installed between 2007 and 2008 saved 3.6 million tons of CO2 from entering the atmosphere; this is equivalent to the carbon output of 16,350 American families (with four people). This particular products’ such effects can be expected from other window films too. In short, all these heat controlling technologies serve to reduce the electricity usage with additional energy conserving effects of reduced carbon emissions. 2.3 Emission Control Speaking of carbon emissions, there are specific uses of materials that combats them. In United States, housing alone takes 38 percent of the total carbon dioxide emissions (EPA). Carbon dioxide emission is one of the well-known factors that are blamed for the global warming. The famous Kyoto Protocol was established in order to limit this and also to achieve better results with global warming around the world. Choice of materials for constructions is thus carefully chosen from the planning stage, since once used in the process of construction, it is hard to replace them afterwards. Different sorts of materials has different amount of carbon emissions, and in green building that is considered as major criteria. Other aspects of renewability and sustainability are also considered carefully when material is picked. One specific example of such effort would be use of wood for floorings. Wood has its advantage as a building material from its characteristics of low embodied energy, low carbon impact, low pollution emission, and sustainability. Low embodied energy means it takes less efforts and resources in order to get it. Wood, since it has minimal energy processing during harvesting, has relatively lower embodied energy than those like steels, concrete, aluminum, plastic. In terms of carbon impact, it has lower carbon emission than most of other construction materials. Compared to other artificial or metal types or materials, it shows significantly lower level of carbon emission just as shown in figure 2. Figure 2 Basically, this is the most important characteristic of wood usage for green building, and it is listed as the followings in the website of The Solid Wood Flooring Company: * For every tonne of CO2 a tree absorbs from the atmosphere nearly  ¾ of a tonne of oxygen is produced * Over 83% of the timber supplied in the UK is certified to be sustainable * Using wood instead of other building materials saves an average of 0.9 tonnes of CO2 per cubic metre. * An ‘EUR’ wooden pallet stores around 29kg of CO2 taken from the atmosphere during the growth of the tree While metals and other fossil-based materials are not renewable resources, wood can be maintained forever if carefully used. It has to be accompanied by careful forestry planning, but it is definitely one resource that can be continuously re-grown. 3. Impacts 3.1 Social Impacts With all the features that efficiently use the natural energy and resources, green building technology also supports well-being of tenants in the buildings. It typically contributes to improve employees’ and students’ health, comfort and productivity. Indoor Environmental Quality (IEQ)—one of the criteria of the U.S Green Building Council’s LEED-H rating system—evaluates the subtle issue that influences people’s status of mind and body in a space. It has been scientifically proven by related study that people tend to be more productive and contribute better performance in environment with better ventilation and proper temperature control (Abdou, 2006). Figure 3 Just as shown in figure 3, improved working or living condition leads to better work performances. The study sponsored in part by commercial real estate giant Cushman & Wakefield, reported 30 percent fewer sick days among one company’s employees, and discovered a 10 percent increase in net revenue per employee in another company, after each office moved to LEED-certified buildings. Schools operating in green buildings also demonstrate higher test scores and heightened academic enthusiasm among students (Abdou, 2006) Plus, nature friendly methods and materials used in green buildings proved to ease sicknesses that could occur in daily lives of tenants. It is believed to contribute widely to respiratory problems, allergies, nausea, headaches, and skin rashes. With much emphasis on ventilation, non-toxic, low emitting materials and cutting use of air conditioning, green buildings indeed create healthier and more comfortable living environments, which keep people away from ‘Sick Building Syndromes’ (Fisk, 2002). In summary, all these benefits retrieved from applying green building technology can lead to wholesome social benefit of people, by promoting health initiatives and pleasurable living spaces. Hence it further goes on to the bigger scale of expanding economic ground, by improving productivity and economic activity of the users of this technology. 3.2 Economic Impacts Green buildings are so much more cost effective compared to conventional buildings. According to the USGBC’s LEED rating system, green buildings tend to be 25-30% more energy efficient and more likely to generate the renewable resource on-site. Due to its cost effectiveness, energy saving and easy maintenance, green buildings outperform non-green buildings in the resale market. Basically a newly–constructed green building will perform 10.9% better than its original construction value. Prospective buyers who realize the utility and maintenance cost and are more concerned about the sustainable design of the building will be attracted towards it. Though there is a common perception that green buildings cost a heavy premium over normal buildings, the cost of green design has dropped in the last few years as the number of green buildings has risen. Hence buildings both residential and commercial with sustainable design component continue retaining a high property value in th e retailing market (McGraw Hill Construction, 2010). By continuing to grow in different ground of constructions from the usual ones, green building technology is opening new opportunities for more economic activities with its prospects. As consumers and suppliers become more interested in such technology, it carries much potential for better outcomes. 4. Future Prospects Then would these outcomes continue to exist in the upcoming future too? Green building is getting on the line of popularity within the general public who are becoming more aware of environmental conservation. Governments are encouraging it with various policies and incentives with brandings. It does seem like there are some positive prospects for green building technology to continue to grow in the future. There are supple amounts of factors encouraging such potentials. Regarding the future upcoming green building designs, buildings such as Zero-Energy Buildings are being explored. Zero-energy building (ZEB) is the designation given to buildings that have zero net energy consumption and zero carbon emissions annually. These buildings harvest energy produced on-site to meet their own energy needs. In addition to this, ideas of green schools are also being developed. Certified Green Schools are growing rapidly as part the LEED System. This trend will accelerate as understanding of the health and educational benefits of green schools grow (Yudelson, 2010). On the other hand, research efforts for further protection of environment are encouraging the future growth too. Awareness of the coming global crisis in fresh water supply leads building designers and managers to take further steps to reduce water consumption to increase sustainability. This will be done in buildings through the use of more conservation-oriented fixtures, rainwater recovery systems and innovative new water technologies. Lifecycle Analysis (LCA) examines the impact of materials and will allow architects to determine what products are more sustainable and what combination of products can produce the most environmentally friendly results (GEP, 2011). In 2011, the annual Image Power Global Green Brands Study polled more than 9,000 people in 8 countries (USA, UK, China, Brazil, India, Germany, France and Australia) to analyze consumers’ perception of green products. All participating countries, either developed or developing, indicated that they were quite willing to open up their wallets and pay a bit more for green options in real estate. Most of the informants showed great interest to the green buildings. To be precise, 60% of the surveyed consumers globally intend to extend their green choices more and more to items in the real estate, energy and technology sectors (Longsworth, 2011). By 2013 overall global green building market, both residential and commercial, may more than double in its scale from approximately $36-$49 billion to $96-$140 billion. When looking solely at the commercial and institutional real estate development markets, the green building market is projected to grow from its current occupation of 10-12% of the market to 20-25% (GreenBuildings.com). The future market trends are predicted to continue to grow with certain incentives and initiatives. One of them would be green building technology being encouraged to be used in government sectors. Government offices will need to be transformed into green buildings because of regulatory requirements in many countries. Such need will be the key growth area for green building market. Cash incentives for developers will play a major role in this too. Singapore, Australia, Hong Kong and Japan have developed strong support system and incentives for green building developers, designers and owners. Seeing benefits from such incentives, more experts will enter into green building area, stimulating its growth (Frost&Sullivan, 2009). 5. Conclusion Green building, regardless its short history, has achieved a lot in a short term. Its variety of technologies gave rise of new solutions for using less energy yet enjoying more nature friendly benefits, and as it get popular, economic and social benefits arose. Specific technologies that have been discussed were temperature control technologies and choice of building materials. Such direct outcomes lead green building’s positive impacts to be applied on overall human society and economy. From the current outcomes of green building technology and its rising popularity, it seems to have good prospects for the future growth too. There are different factors of future designs and economic incentives encouraging this trend, and so further growth followed by more positive impacts can be expected. These all consequently support the idea; green building has substantial positive effect in both environment and economy, with potential for even better outcomes in the future. Still, there are problems and limitations of green building technology that we have to consider about for the moment. It is a new born technology and yet to be fully developed. Hence full green buildings that incorporate much of the technology are prone to be accused for its high costs as mentioned before and also its insufficient development of efficiency are often pointed at as something unworthy of further developments. Nevertheless, its future potentials cannot be abandoned simply because of its current limitations. Since the initial goal of green building is to reduce human use of natural resources and promote sustainability, current green building technology should be pushed on for further developments that can solve problems at the moment and so forth move on to achieve its goal in an even better way. Besides, its potentials are sufficient to predict better efficiency and profound benefits for our society. Hence green building technology should be acknowledged for its supportive impacts on environment not only for the current moment, but also for the upcoming future that will aid human beings to continue to live on without exhausting the natural resources.

Taking a Look at Hurricanes - 625 Words

Hurricanes are first formed when warm ocean water makes energy for the hurricane and causes evaporation making air and clouds. The ocean water temperature has to achieve at least 80 degrees fahrenheit for it to provide energy for the hurricane. The winds will then end up colliding and force the winds upwards. After the winds have flown upward, they will flow outward above the storm which will make the air rise. Lastly, the light winds outside the storm will let it grow into a national storm. There are many tropical stages a storm has to go through before reaching the final hurricane stage. The first stage is called a tropical wave. A tropical wave storm is basically a low pressured storm following the trade winds. The second stage is called a Tropical Disturbance. A tropical disturbance is an area of thunderstorms that will usually form in the tropics area.These storms only last for about a day at the most and usually produce heavy rain and gusty winds. The third stage is called a Tropical Cyclone. A tropical cyclone is similar to a tropical wave. It produces a low pressure storm but they develop usually over tropical and sub-tropical waters. The fourth stage is called a Tropical Depression. A tropical depression is a medium- pressure storm with winds approximately 38 mph or less. These storms are one of the first stages when meteorologists are studying a certain storm forming. The fifth stage is called a Tropical Storm.

In 1575 Arminius started attending the University of Leyden. While there, the municipal authorities of Amsterdam agreed to pay all of Arminius’s academic expenses in return for his pledge to spend the remainder of his life serving the Amsterdam church (Christian History Institute). A year after he began his public ministry in 1588, the ecclesiastical senate of Amsterdam asked Arminius to respond to the teachings of Dutch poet, translator, playwright, and moralist Dirk Coornhert. Coornhert rejected much of Calvin’s doctrine of predestination, justification, and punishment of heretics by death (Christian History Institute). â€Å"Weighing the arguments, Arminius thought Coornhert right, but would not commit himself until he had made a diligent study of the scriptures, the early church fathers, and later divines† (Christian History Institute).

Comparison of hybrid vehicles with other types of power units Free Essays

1 Introduction 1.1 Investigation Purpose The times of low inflation have gone, especially in the resources centre and this is as a result of fossil fuels being capped with limit. Unfortunately, we can not reserve fossil fuels, such as coal and oil forever, though what we can do is introduce another power source for the likes of vehicles, whether this is a slowly but surely start, any positive impact on our fuel consumption as a whole and reduction of global warming. We will write a custom essay sample on Comparison of hybrid vehicles with other types of power units or any similar topic only for you Order Now There is a vital need of this information to be distributed to individuals around the world, as whether it is our generation which faces the issue of green house gas emissions or the future generation, one way or another we have to deal with it. The idea is to make the world realise that term ‘hybrid’ is feasible and available to everyday consumers, of course at a price, but what isn’t I will extract data from various research and development programs and compare it to the current hybrid’s which are available and observe the room for improvement. The contribution that will be put in has its limits, as I can not produce a new alternative or redevelop a current form, though it is my duty to identify and produce evidence of the type of hybrid and power units that can modernise today’s world effectively, safely and most importantly cleanly. I will determine how the new generation of hybrid cars, which uses a combination of two or more distinctive power units to move a vehicle. This will include the comparison with conventional power units, such as petrol and diesel engines. A thorough analysis will also be carried out, along with advantages and disadvantages, in relation to efficiency, resources, safety, performance emissions and other deriving factors. Hybrid vehicles are deemed to be the future for vehicle transportation, as fossil fuels are diminishing, whilst pollution is greater than ever. Technically, this is a resultant substitute for the conventional power source, though does this ultimately ridden the problemIf this is the case, would it a short or long term change? 1.2 Methodology I will extract information from various sources, including textbooks, internet and applying my common sense and literature towards it. I will firstly research in depth on the subject, and then followed by planning and structuring the report. I will use comparative arguments in order to review hybrid cars and other fuel types. 2 Hybrid Vehicle 2.1 History Since the early 1900’s, car designers have been experimenting with electric and hybrid power units. Hybrid vehicles were produced beginning as early as 1899 by Lohner-Porsche, who is best known for creating the first hybrid vehicle (gasoline-electric), the Volkswagen Beetle, the Mercedes-Benz SS/SSK, as well as the first of many Porsche cars. Early hybrids could be charged from an external source before operation; hence the term plug-in hybrid has come to mean a hybrid vehicle that can be charged from a standard electrical wall socket. While employed at Lohner Coach Factory, Ferdinand Porsche developed the Mixte; a 4WD series-hybrid version of â€Å"System Lohner-Porsche† electric carriage previously appeared in 1900 Paris World Fair. The Mixte included a pair of generators driven by 2.5-hp Daimler IC engines to extend operating range and it could travel nearly 40 miles on battery alone and it was presented in the Paris Auto Show in 1901. The Mixte broke several Austria n speed records, and also won the Exelberg Rally in 1901 with Porsche himself driving. The Mixte used a gasoline engine powering a generator, which in turn powered electric hub motors, with a small battery pack for reliability. It had a top speed of 50 km/h and a power of 5.22 kW for 20 minutes. As a result of this, the internal combustion had reformed as the ‘best’ at the given time and inheriting the power source for automobiles for over a century. Between this time, petrol and diesel powered vehicles took the opportunity to boost their technological advancements, which included fuel injection and computer controlled systems that aided the fuel efficiency, safety and power. 2.2 How it functions As we know, a conventional car has a fuel tank, along with an internal combustion engine and a transmission, which ultimately work simultaneously to turn the wheels of the car, thus making movement. In saying so, the fuel tank allocates fuel, such as petrol or diesel to the engine and therefore, the engine processes the fuel through the transmission, causing the wheels to turn. Like all batteries, hybrid batteries have two electrodes (which collect or emit an electric charge) that sit in an ion-rich solution called the electrolyte. (An ion, by the way, is an atom or group of atoms with an electrical charge.) The electrodes are typically very close, so a polymer film, called a separator, prevents them from touching, which would create a short circuit. An on-off switch in whatever device is powered by the battery—your phone or laptop—bridges the cell’s electrodes to generate power. That’s when the electrochemical reaction begins. Keep in mind: What we commonly call â€Å"a battery† is actually a battery pack that houses many individual cells. Your mobile phone battery is just one single cell, but anything larger—even a laptop battery—uses multiple cells working together. Ionized elements in one electrode are in a chemical state where they are easily attracted to combine with other molecules, emitting electrons (energy) in the process. Those elements are tugged through the electrolyte and the separator toward the opposing electrode. The ions of the negative electrode (anode) give up electrons; the positive ions coming toward the anode accept them. The electrons released during this process travel through the external circuit (e.g. your phone), producing a flow of charge in the opposite direction to the flow of ions. During recharge, current is forced into the cell, reversing the process. As we take a tour of hybrid batteries, remember one thing: Total energy determines the vehicle’s electric range, whereas available power determines its acceleration. (http://www.hybridcars.com/hybrid-car-battery ­) On the other hand, a hybrid vehicle consists of two parts, the internal combustion engine and the electric motor to form motion on the vehicle. Furthermore, the means of this is so that depending on the environment the vehicle is driving in, it will switch between the fuel engine and the electric motor, in order to maximise efficiency. Examples of this would be whether the vehicle was driving through urban or rural roads or even dependant on speed. This particular combination is called HEV (Hybrid Electric Vehicle) and is also important to note that is predominately used with diesel as the fuel 2.3 Types of hybrids There are many types of hybrids and whilst some are quite similar to each other, in terms of functionality, they are in fact two diverse designs. However, they are both built around improving fuel mileage and better the emissions to limit the harm to the environment. The Mild hybrid focuses more on the traditional fuel engine, whilst integrating the three major components. It is conveyed around the assistance of the electric motor’s function for the fuel engine. In the case of conventional vehicles, motion of the force is what makes it a fuel engine. In addition to this, the electric power only comes into the picture when further power is needed. Due to the fact that the vehicle is only using energy where essential, it is increasing fuel mileage. This design has enabled the electric motor to do more than one task, which is either charge the vehicles battery or use vital electricity to help boost the performance of the vehicle. Unfortunately, the design has limited the possibility of doing both tasks simultaneously. Honda is a prime example of Mild hybrid systems, developed in models such as the Civic and Insight. On the other hand, Full hybrid vehicles are designed differently, but the three key components are well and truly there. However, this is deemed to be more complex, in terms of benefiting the vehicle. The Full hybrid is able to utilise its electric motor independently under certain conditions of the fuel engine. The electric motor will take over, depending on certain models, which means if the vehicle is moving at a constant lower speed and will only have use of the fuel engine when acceleration is required. Though, if the fuel engine permits it, they can both work simultaneously. Periods of high speed, like in the case of highway passing is an example of the two engines working together. Full hybrid cars are capable of both charging and using energy from the battery at the same time. Ultimately, whether the vehicle is mid or full hybrid, they are both economically friendly, reducing emissions, whilst increasing whole life cost to include cost of manufacture. 2.4 Technology You can argue that, although the HEV is combined, the battery or electrical motor would still need to run on chargeable cells, thus being expensive. However, the defining feature the HEV has is its RESS (Rechargeable Energy Storage System), which productively allows the system to be recharged, from the actual process of operating the vehicle and does not need any form of ‘plugging in’. For example, the regenerative breaking converts the vehicles kinetic energy into energy, which is stored by the battery or capacitors. Hydrogen Fuel Cells: Hydrogen fuel cells consist of: Anode Membrane Cathode Electro engine Power electronics Batteries Hydrogen tank A fuel cell is a combination of electrodes sandwiched around an electrolyte. Oxygen passes over one electrode and hydrogen over the other, generating electricity, water and heat. There are two main hurdles that stand in the way of mass production and widespread consumer adoption of hydrogen fuel cells. One is the high cost of producing fuel cells, which cost $1million to produce one vehicle and Toyota and Honda are currently leasing to Japan and California. It is important to note that, although it seems very expensive to produce a vehicle right now, Toyota is hoping to reduce this cost to $50,000 by 2015. I believe that the current cost would not make a make a difference to society, as the same with the current hybrid of electric vehicles. The reason for this is because everything is in production and to be quite honest, the world is not ready for a huge step, especially when the acceptance of hybrid vehicles as a whole is still in acceptance and surge of demand still waits. The second issue, which of course is in relation to the first, typically consists of the lack of hydrogen refuelling stations. As we all know, it is safe to say that majority of vehicles on the road are under the influence of petrol or diesel applied engines. Therefore, oil companies may be reluctant to push the idea of hydrogen fuel, when they are perfectly indulging in their most profitable sector – petrol and diesel. And why not thoughIt is fairly logical to stand by your current business affairs when they are keeping yourself and shareholders happy. Though to be fair, Shell and BP have been promoting this idea and working with a dealership, which I will elaborate further down. There are many factors involved in which understandably fright oil companies, such as safety, cost and of course, lack of demand. However, one company which has an extremely good reputation with hydrogen being their middle name and this is the ‘California Fuel Cell Partnership’. They are a non-profit based company, who admire the concept of ending petroleum dependence and making a positive change to society. We can question whether this direction is possible or whether consumers will ultimately accept it, but without research and attempting to better the need for zero emissions as a whole, we will never know, rightAs of now, we do not know any better, we isolate ourselves with the nature of life, believing that life today, will consist of the same resources in 50-100 years’ time – or do we know the truth about commodities and turn a blind eye to limited resources and let the future generation deal with it – perhaps. The California Fuel Cell Partnership is a public-private partnership to promote hydrogen vehicles (including cars and buses) in California. It is notable as one of the first initiatives for that purpose undertaken in the United States. In January 1999, two state government agencies—California Air Resources Board and California Energy Commission joined with six private sector companies—Ballard Power Systems, DaimlerChrysler, Ford Motor Company, BP, Shell Hydrogen and ChevronTexaco—to form the California Fuel Cell Partnership. The goal was to demonstrate and promote the potential for fuel cell vehicles as a clean, safe, and practical alternative to vehicles powered by internal combustion engines. Within a very short time, other government agencies and private businesses became members. In November 2000, the West Sacramento headquarters opened. The building includes a public gallery, offices, hydrogen fuelling station and indoor service bays for vehicle maintenance. At first, the automakers had just handful of cars all stationed in Sacramento. The goal was to see if these vehicles and fuel could be technically viable. If the answer was no, then CaFCP would close its doors in 2004. Before the first phase was finished, CaFCP members knew that the technology could succeed. The number of members grew to 33 and set a new set of goals for the next phase of operation, from 2004-2007. During this period, CaFCP members worked on project to prove or disprove the commercially viability—would the vehicles, fuels and public policies meet consumer expectations? In mid-2006, the members agreed that FCVs could be a commercial success. They agreed to a third phase through the end of 2012 to lay the foundations for a commercial market, which includes developing early retail stations, policies to enable the sale of retail hydrogen and necessary steps to building a supplier base for large-scale production in the future. CaFCP completed its first phase of operation in December, 2003. The second phase will conclude in December, 2007. In mid-2006, the members agreed to enter a third phase to encourage fuel cell vehicle commercialization that will continue through 2012. The California Fuel Cell Partnership is a unique collaborative of auto manufacturers, energy companies, fuel cell technology companies and government agencies. The members collaborate on activities that advance the technology, such as first responder training, community outreach and agreeing on protocols while standards are being developed. Automotive members provide fuel cell passenger vehicles that are placed in demonstration programs, where they are tested in real-world driving conditions. Energy members work to build hydrogen stations within an infrastructure that is safe, convenient and fits into the community. Fuel cell technology members provide fuel cells for passenger vehicles and transit buses. Government members lay the groundwork for demonstration programs by facilitating steps to creating a hydrogen fuelling infrastructure. What is the difference between a fuel cell and a battery? Fuel cells and batteries are similar because they use a chemical reaction to provide electricity. A battery stores the chemical reactants, usually metal compounds like lithium, zinc or manganese. Once used up, you must recharge or throw away the battery. On the other hand, a fuel cell actually creates electricity through reactants (hydrogen and oxygen) stored externally. The fuel cell will produce electricity as long as it has a fuel supply. In short, a fuel cell vehicle is refuelled instead of recharged. Why is it taking so long? Well, this is a question everyone wants to know the answer to, I mean if there, why not release itThe problem is, technology, especially being new takes many years to come to the market. Before selling anything, it is important to create and enforce regulations and standards, to ensure that consumers get what the pay for. The California Fuel Cell Partnership is a prime example of their members working together on the barriers which front us all and by doing so, they can streamline a process from years to months. Is hydrogen a safe fuel? The term ‘fuel’ is not to be taken lightly and when dealing with any type of fuel, it is important to handle with care, just as hydrogen is done. For more than 50 years, hydrogen has been produced and used for commercial and industrial purposes with an exemplary safety record. Like all fuels, hydrogen has high energy content and must be handled with care. CaFCP’s members are building fuel cell vehicles and fuelling stations that meet or exceed safety standards. In addition, our members are defining new safety measures. Like gasoline and other fuels, hydrogen is flammable. Unlike conventional fuels, it is very buoyant. With proper ventilation, hydrogen dissipates rapidly into the air, greatly reducing the chance of fire. Hydrogen is non-toxic, so if released it does not present a health hazard to humans and its effect on the environment is benign. Petroleum Dependency and Fuel Cell Vehicle’s Vehicles in the U.S. consume twice as much oil as the country produces. The number of vehicles on the road and the number of miles they drive increases every year, but U.S. oil production capacity remains about the same. In 2008, nation (U.S) consumed about 213,810 gallons of gasoline daily—78 million barrels of oil in just one year. (A barrel is 42 U.S gallons.) The National Research Council projects that by 2050 they will consume about 1.5 billion gallons of gasoline a year, assuming that most of the vehicles on the road are highly efficient conventional, hybrid and flex fuel vehicles. If most of the vehicles are fuel cell and battery electric vehicles, gasoline consumption decreases by almost 70% to less than 50 million gallons a year—roughly half the current domestic oil production. 3 Current Issues with Conventional Vehicles 3.1 Fuel Capacity Fuel consumption and fossil fuels as a whole are again, diminishing is one of the reasons why hybrid vehicles and other power units are an opportunity cost. On top of this, the annual fuel cost is increasing for conventional cars, whether it is petrol or diesel. Due to the environment we live in, it is impossible to rely on the fossil fuel itself to increase Miles Per Gallon, instead the only option is to render the current technology of the vehicle. Nevertheless, there are myths out there which try to better than conventional car with the likes of driving economically or using premium petrol, but how real are these mythsWell according to Susan Winlaw, co-author of the book, Car Advice for Women (and Smart Men says, â€Å"Unless you have a job that requires regular sessions on a racetrack, there is no legitimate need to ever put premium fuel in your vehicle. Using regular gas could cost you a few horsepower when you’re driving at higher speeds, but chances are you won’t notice the difference, and it definitely won’t hurt your car. Your engine’s fuel-management system is perfectly prepared to handle lower-octane fuel† says Winlaw. (Source:http://moneywatch.bnet.com/economic-news/article/6-myths-about-gas-mileage/317188/). Well, this is down to personal experience and most importantly, trial and error, unless this is a fact, as the norm would be, most individuals would not want pay the higher price to observe savings, when fuel prices are costly in the first place. So how do we be more economicalDo we drive with our air conditioning off or do we drive the road speed limitIn my experience, I was never fond of speed cameras being put left, right and centre and the daring part of being on the lookout for those cars with the flashing lights. Though I have to say, driving according to the road speed limit actually increased my MPG from A to B, which thoroughly surprised me to say that I do favour speed cameras and speed limits. In relation to this, it has been stated in reality ‘fuel efficiency doesn’t really start to drop until you reach speeds higher than 60. And how smoothly you drive makes much more of a difference on petrol mileage than how fast.’ 3.2 Environmental Issues Another major factor of changing our system is environmental factors. Global warming is amongst one of the major factors, for example just burning a gallon of petrol when combined with oxygen; it produces almost 20 pounds of Carbon Dioxide CO2. The idea from moving to a more ‘green’ vehicle from a conventional can literally reduce the number of greenhouse gases emitted by SI units. There have also been ways for awareness, such as energy rating for vehicles. The useful part we want is movement. We measure the weight of the vehicle and determine how much energy is being delivered to accelerate or maintain movement of the vehicle against external resistance. Then we could compare this to the amount of energy being put into the system. Useful power out over power input will give you the efficiency. As a result, the higher the CO2 emissions, the higher rate of road tax you will pay on the vehicle. Below is a diagram illustrating the CO2 emissions chart: Figure 1 At the end of the day, scientists and engineers are attempting to overcome obstacles, taking cars from the laboratory to the showroom, so that the first affordable and realistic car powered by hydrogen and pollution-free is driven by a child born today for their future. The government has pledged $1.7 billion in the U.S. for hydrogen research and development over the next five years, securing funding, however the objective is to overcome the obstacles involved in making hydrogen a viable energy source. There is a high significance of environmental benefits of hydrogen, whether individuals believe it or not, as facts are facts, hydrogen can be pollution-free and infinitely renewable through wind, solar and hydropower sources. Either way, the importance is high, I mean, how long can we keep surviving on ‘non-renewable’ sources for? However, the phrase ‘nothing is free in this world’ is true, in my opinion and you can not blame critics, who argue that the fuel source does have its environmental drawbacks; as they say, nothing is perfect. According to the National Hydrogen Energy Roadmap, it said that it requires up to 90 percent of all hydrogen has been refined from non-renewable sources, oil, natural gas and other fossil fuels. Does this mean we’re back to square one or is this just a stepping stone? So we agree that the extraction of hydrogen from fossil fuels may not be environmentally friendly, though once the hydrogen is in a fuel cell car, only water vapour and heat will be expelled from the exhaust. But it is the burning of the fossil fuels, which are used obtain the hydrogen and this releases carbon dioxide, which is the primary cause of global warming. Even some scientists say that the hydrogen which has been extracted from fossil fuels creates an impact of the environment by releasing carbon dioxide in the air, which defeats the point of a clean-energy provider. On the other hand, were bridges built with a perfect structureOr were car engines primarily built efficientlyI think not, so my point is that we need to use current fossil fuels to perform trial and error, hence the term ‘hybrid’. But most importantly, this is all for the future and the main thing is that were making progressive now, whether it requires other sources of elements which contradict itself, though we just merely use it as a stepping stone. President Bush’s 2004 budget asks for more than $22 million for hydrogen research and development to be devoted to coal, nuclear power and natural gas, and $17 million for renewable sources. â€Å"Cutting RD for renewable sources and replacing them with fossil and nuclear doesn’t make for a sustainable approach,† said Jason Mark, director of the clean vehicles program for the Union of Concerned Scientists. A recent study warns of the danger of releasing hydrogen itself into the atmosphere. Los Alamos researcher Thom Rahn led a team of scientists from California universities and the National Centre for Atmospheric Research in Boulder, Colo. Their study of the natural cycle of atmospheric hydrogen was recently published in the British science journal Nature, and finds that substantially increased hydrogen production has the potential to damage the upper atmosphere. Escaped hydrogen could build up, depleting the ozone layer near the North and South poles and triggering an increase in global warming. The study also warns that hydrogen may further contribute to global warming by aiding other chemicals in producing increased amounts of water vapour in the upper atmosphere. â€Å"It is impossible to manufacture, store and transport hydrogen without at least some fractional loss (to the atmosphere),† Rahn said. Researchers from the California Institute of Technology estimate that leaked hydrogen in a hydrogen economy could cause as much as a 10 percent decrease in the stratospheric zone. If hydrogen replaces fossil fuels as the world’s main energy source, the researchers believe that each year 60 trillion to 120 trillion grams of hydrogen could be released into the atmosphere. This is four to eight times the amount that is currently released. The impact of increased hydrogen production depends on how well the earth adapts to the change. John Eiler, assistant professor of geochemistry at CalTech, said, â€Å"This man-made hydrogen will either be absorbed in the soil — a process that is still poorly understood but likely free of environmental consequences — or will react with other compounds in the atmosphere. Determining which of these two processes dominates should be a solvable problem.† Tracey Tromp, another CalTech researcher, contends that early recognition of problems will mitigate hydrogen fuel’s environmental flaws. â€Å"If hydrogen emissions present an environmental hazard, then recognizing that hazard now can help guide investments in technologies to favour designs that minimize leakage,† Tromp said. The CalTech researchers, like other scientists looking at the environmental impact of increased hydrogen production, believe that the sooner such problems are identified, the easier it will be to find solutions to make a hydrogen economy truly feasible. 4. Hybrid – Environmentally Friendly 4.1 Benefits of a hybrid compared to a conventional The hybrid vehicle typically achieves greater fuel economy and lower emissions than conventional Internal Combustion Engine Vehicles (ICEV), resulting in fewer emissions being generated. These savings are primarily achieved by three elements of a typical hybrid design: Relying on both the engine and the electric motors for peak power needs, resulting in a smaller engine sized more for average usage rather than peak power usage. A smaller engine can have less internal losses and lower weight. Having significant battery storage capacity to store and reuse recaptured energy, especially in stop-and-go traffic, which is represented by the city driving cycle. Recapturing significant amounts of energy, whilst braking that are normally wasted as heat. This regenerative braking reduces vehicle speed by converting some of its kinetic energy into electricity, depending upon the power rating of the motor/generator. Other techniques that are not necessarily ‘hybrid’ features, but that are frequently found on hybrid vehicles include: shutting down the engine during traffic stops or while coasting or during other idle periods; Improving aerodynamics; (part of the reason that SUVs get such bad fuel economy is the drag on the car. A box shaped car or truck has to exert more force to move through the air causing more stress on the engine making it work harder). Improving the shape and aerodynamics of a car is a good way to help better the fuel economy and also improve handling at the same time. Using low rolling resistance tyres were often made to give a quiet, smooth ride, high grip, etc., but efficiency was a lower priority). Tyres cause mechanical drag, once again making the engine work harder, consuming more fuel. Hybrid cars may use special tyres that are more inflated than regular tyres and stiffer or by choice of carcass structure and rubber compound have lower rolling resistance while retaining acceptable grip, and so improving fuel economy whatever the power source. Powering the A/C, power steering, and other auxiliary pumps electrically as and when needed; this reduces mechanical losses when compared with driving them continuously with traditional engine belts. These features make a hybrid vehicle particularly efficient for city traffic where there are frequent stops, coasting and idling periods. In addition noise emissions are reduced, particularly at idling and low operating speeds, in comparison to conventional engine vehicles. For continuous high speed highway use these features are much less useful in reducing emissions. 4.2Vehicle Emissions According to the EPA (Environmental Protection Agency), the recommended level for a typical passenger should equate to 5.5 metric tons of CO2. However, the three most popular hybrid vehicles have set a new standard by consistently reducing their emissions and surpassing the recommended levels. The vehicles are the Honda Civic, which produces 4.1 tons SI units, the Honda Insight at 3.5 tons SI units and last but not least, the Toyota Prius also being 3.5 tons SI units of CO2 emissions. 4.3 Buying a hybrid vehicle A hybrid car gets a much higher mileage, up to ten percent in some cases, and emits 97% less toxins into the environment than the average car. They are lighter and have a gentler impact on roads and soft terrain. With the price of gasoline soaring, a car that can run on both gas and electricity, depending on the circumstance, is a big advantage. Most people who decide to buy a hybrid car, however, cite a â€Å"feel-good factor† as their main reason for buying the car. It is their small way to contribute to a greener world. Despite all the benefits cited above, a hybrid car also has some downsides. For starters, they are expensive. A hybrid car tends to be more on average of ?3000, which is sometimes more expensive than a traditional car. They cost more to register, and repair costs tend to be hefty, as the entire car systems are intrinsically connected, and only expert mechanics can handle repairs. Parts may not be readily available, which could mean being without a car for a longer period as you is waiting for it to be repaired. 5. Planning Schedule Gantt chart: Conclusion: The information gathered can be elaborated excessively, though I will quantify the relevant information where necessary. This preliminary report demonstrates how much of a positive impact hybrid vehicles have and how fuel efficiency in various sectors, such as fossil fuels and global warming can be significantly reduced. As for hybrid vehicles themselves, it illustrates their efficiency in major development, for years to come. They have proven to be more effective than conventional vehicles and although they may be more expensive now, the long term effects are more beneficial.
