Algae derived biofuel

Algae derived biofuel Abstract The first section of the paper focuses on a background or historical context of algae derived fuels for aviation. It was found that the technology is relatively new. Tests have been done by several aviation firms but no fleet is powered by the fuel. After coverage of developments in the sector, the advantages and limitations of the fuel source were identified.Advertising We will write a custom research paper sample on Algae derived biofuel specifically for you for only $16.05 $11/page Learn More Advantages include low greenhouse emission, similarity to conventional jet fuel and no competition with food. Limitations include poor commercialization, lack of incentives and costliness. Thereafter, some recommendations were made on how to make this technology viable. They included private-public sector collaboration, improvement of the production process, government investment, sensitization of the masses and mobilization of stakeholders for standardizati on. Introduction Concerns about the rate of green house gas emissions necessitate the shift to more sustainable fuels. Algae-derived jet fuels have been suggested as possible solutions to this problem. However, most producers are still at the research phase of the product life cycle. It is, therefore, necessary to analyze the past and present trends in order to identify future possibilities. Methodology The study involved secondary research where journals, books and newspaper reports on the subject matter were collected. In this analysis the need for using the fuel was one of the topics identified. Furthermore, a historical analysis of the development of this fuel in the aviation industry was done. Thereafter, some articles were collected on adoption of the fuel in various industries presently. The disadvantages and advantages of the fuel were examined. Finally, an analysis of findings was done in order to make a forecast on future developments. Findings Historical context The aviat ion industry is one of heaviest sources of pollution in the world. Statistics indicate that for every fifty units of greenhouse gas generated on the earth, one unit will come from the aviation sector. This number may increase to 1.5 units in the next half a century. Consequently, sustainable and effective ways of dealing with this high carbon footprint are necessary.Advertising Looking for research paper on environmental studies? Let's see if we can help you!

Some of them have suggested the use of biodiesel, but its propensity to solidify in cold conditions makes it untenable (Shirvani et al. 2011). Others have suggested the use of FT SPK, which involves the use of solid biomass to generate oil through a process known as pyrolysis. The product is then transformed into the synthetic paraffinic form of kerosene that is used in ai rplanes. The major problem with this approach is that it is quite resource consuming. Firms also have the option of using oil from algae in order to create synthetic kerosene through a process of hydro processing (Agricultural Research and Cooperative Extension 2012). The latter approach is the focus of the paper. Algae-derived fuels have gained popularity in the late 2000s. However, most research on them started in the 1990s. During the year 2008, several aviation stakeholders such as the Boeing, Virgin Atlantic, and Air New Zealand formed the Algal Biomass Organization. In January 2009, Continental Airlines tested the first commercial jet using a blend of algae-derived fuels. At the time, a 50-50 combination of the conventional fuel and algae biofuel was used (Kyriakos 2012). In July 2010, the first plane to be powered by 100% algae-derived biofuel was flown by Airbus maker-EADS. The demonstration was done in Berlin and then England. It was found that the fuel was more efficient t han the conventional ones. About fifty percent less fuel was needed compared to a petroleum-derived fuel. Even the unwanted emissions were drastically reduced. The company estimated that eight times as much greenhouse gases are produced by conventionally-powered aircrafts. In September 2010, Exelon Corporation worked on a new method of algae production that could be sustained even during cold temperatures. In June 2011, Honeywell, which specializes in the production of jet fuel from algae, tested a Gulftstream jet using a blend of the algae fuel as well as petrol in an equal ratio. The aircraft belonged to the US military and thus demonstrated that this government had faith in the possibilities of the fuel. Even the Navy in the US powered a helicopter for the first time with a blend of algae biofuel. It was reported that the aircraft was just as efficient as a conventionally-powered aircraft (Goldenberg 2010|). During the month of October, an organization known as Pond Biofeuls Inc. found a way of growing algae from cement plant emissions. However, the quantities were still minimal in number.Advertising We will write a custom research paper sample on Algae derived biofuel specifically for you for only $16.05 $11/page Learn More In November 2011, another Aircraft departed from a city in the US (Houston) to another – Chicago. In the first month of 2012, an organization known as VG Energy discovered a new method of producing algae that could increase the amount of oil that it produces by 700%. Current uses (benefits and limitations) The most promising aspect of algae-derived biofuel is their environmental sustainability. Aviation companies that belong to sustainability associations often have to follow certain criteria before adopting a fuel as an alternative. The source of the fuel should not cause pressure in food production. Oils derived from corn or other food products are deemed unsustainable because they lead to competition between humans who need the seed for food and those who want to make fuel out of it (Scott et al. 2010). Algae-derived fuels do not threaten food production because human beings do not eat algae. In addition to competition for food, the plant source of the biofuel ought not to use up land for farming. If a plant needs to be grown in the same way as other food crops, then it may use up a lot of land and prompt residents to practice deforestation. Once again, algae-derived biofuels do not have this quality because they are not grown on land. Most of them can be cultivated in salty water or even polluted water, yet they can yield as much as two hundred percent more oil than soybeans. Therefore, they will not cause depletion of natural resources like forests or water. Lastly, sustainable fuel should not lead to high amounts of carbon emissions in the air. The carbon lifecycle of the product needs to reduce greenhouse gases in the atmosphere; otherwise, the fuel would not be environmenta l friendly. This trait is quite true for the fuels from algae; it minimizes the availability of greenhouse gases by 50% (MIT 2012). In order to use a substance as a sustainable fuel, it must possess certain chemical characteristics that make it suitable for this purpose. The chemical composition of the product should allow it to be mixed with normal fuel for use. Jet fuel ought to have high tolerance for extremely hot and cold weather; this is true for algae-derived fuels.Advertising Looking for research paper on environmental studies? Let's see if we can help you! Get your first paper with 15% OFF Learn More That requirement means that automotive derived alternatives cannot be suitable for aviation. The algae-derived fuels clearly fit this description. The sustainable fuels also need to be similar to conventional jet fuels in order to minimize the need for aircraft adaptation of the engines, which is another quality that the fuel under analysis possesses. Despite these tests, even on commercial airlines, most companies are yet to treat algae-derived biofuel as a reliable source of fuel. In fact, most research organizations are still working on ways of producing the algae at a large scale. Most organizations working on the technology are in educational or research institutions. The University of London and Cambridge are some of the many institutions researching on sustainable mechanisms for producing algae. Therefore, the reliability of the fuel is still questionable. For effective use of the technology, aviation companies need to take advantage of incentives offered for use of an altern ative fuel. Currently, some governments have given their aviation companies reprieve by providing incentives. In the United States, the government has passed a law that allows aviation firms to buy alternative fuels, including algae-derived ones, at fair prices. These benefits are accorded to members of the Renewable Fuel Standard group. However, several other countries do not possess such incentives thus making it difficult to try out algae fuels (Hartman 2008). The nature of business is also minimizing the adoption of this fuel commercially. Using biofuels in aircrafts is an expensive practice because one has to pay more per unit of fuel consumed. These high prices have dampened demand for the product. Investors, in turn, have avoided the product because it may be considered as a high-risk venture. Furthermore, whenever a technology is in its early stages of discovery, many investors tend to refrain from it until it picks up. Government bodies can come in and provide incentives fo r the use of the product. However, because only a small portion of these subsidies and deductions exist in aviation, then adoption of the technology may take long (Yang et al. 2010). Discussion Politics will play a large role in the adoption and use of algae-derived biofuels. The international business environment is not suitable for the use of these fuels unless governments step in and change the way things are done. Governments can collaborate with other sustainably oriented countries in order to create standards for the use of algae-derived fuels. The European Union has already started working on this aspect. Other countries, including Australia need to follow suit; otherwise, the adoption of the technology will continue to take too long. Additionally, governments can create incentives for the use of these fuels, and that would encourage more companies to use it. Governments also have the power to invest in this emerging technology. They can empower businesses who may want to sta rt with demonstration plants. Governments should try as much possible to treat algae-derived biofeuls as other fuels used on land transport. That would imply that the product is being taken seriously. People would invest in it and thus develop it. As the case is now, people still think of the technology as a reserve for wealthy aviation firms with extra amounts of money to spare (Greenwell 2010). Conventional jet fuel is sourced from firms that have well established production facilities. Since these companies have been in the industry for so long, they often take advantage of economies of scale and thus make their products affordable. Furthermore, they are easily accessible to aviation firms because they have an expansive distribution network. However, this is not true for algae-derived products. Few companies have large production facilities that can accommodate an increase in demand. Additionally, these organizations do not have a vast distribution network thus making it difficul t for customers to rely on their prompt response when in need of fuel. In order to match current demand levels of conventional jet fuels, companies should invest as much as $15 billion dollars in the new technology. Clearly, this is a large sum of money and few companies are yet to make such a commitment. Few partnerships exist between the government and public sector thus implying that all the opportunities available for the development of this technology are not being exploited fully (Teixera 2012). Conclusion Algae- derived jet fuels are quite promising because they provide an answer to most of the problems created by other biomass derived products. Not only are there no threats to food security or land resources from algae, but it easily blends with conventional fuels thus eliminating the need to change aircraft parts before use. However, the major problem with this fuel is that it is still in its early stages of development. No company has a distribution network that can sustai n the commercial production of the same. Few government incentives exist to encourage investment in the technology. Additionally, stakeholders are not cooperating or sharing resources in order to make the development even more promising. Unless these flaws are corrected, then prospects for commercialization of algae-derived jet fuels still remain slim. Recommendations The first approach that companies need to embrace is research and development. More should be done in order to ensure that commercialization of the fuel occurs. Firms have already discovered effective sources of algae feed stocks. Now they need to work on the refining process so as to convert it into a large scale endeavor. Since algae-derived fuels are new technologies, then governments should try to reduce risks in investing in this sector through public-private sector collaborations. There is a need for incentives that would encourage airlines to use the product. Investments and collaborations should be done in orde r to encourage creation of a clear network. Countries should mobilize other nations and convince them to join algae sustainability groups. This would cause them to commit to certain standards and thus develop the sector. Lastly, stakeholders ought to be empowered about the importance of algae-derived jet fuels. If they can understand the groundbreaking advantages that emanate from the technology, then they may become participants in its development.

Mary Mount Universitys Student Code of Conduct Essay

Mary Mount Universitys Student Code of Conduct - Essay Example The Section 4 of Mary Mounts community code of conduct contains the special provision in part b which is very disturbing – it witchhunt on its perceived misconduct online. Students are cautioned that behavior conducted online, such as harassment or bullying via email, can subject them to University conduct action. Students must also be aware that blogs, web page entries on sites such as MySpace, Facebook, and Twitter and other similar online postings are in the public sphere and are not private. These postings can subject a student to allegations of conduct violations if evidence of policy violations is posted online. The University does not regularly search for this information but may take action if and when such information is brought to the attention of University officials. This is a chilling provision because, in effect, students cannot post or write anything that school officials might not like. It covers blogs, web page entries on sites such as MySpace, Facebook, and Twitter and other similar online postings under the license of bullying and harassment which would be difficult to interpret. For example, if a student rants about his or her disappointments which are typical among college students, and it was reported to school administrator as harassment, the student will be in trouble as what the special provision on Section 4 states. In effect, this provision dictates its student to only write and post nice things which are a gross violation of the freedom of speech as guaranteed by the Constitution in the First Amendment.

The F-test is characterized by negative F values and a non-symmetric distribution of values. Additionally, the mean of the F-test is 1. The major purpose of the F-test is to ascertain whether the variances of two populations are equal. In this regard, the ration is one when the population variances are equal. In the above case, the population variances were equal because the F significance is 0. F-test applies when the null hypothesis is true. The F-test is denoted by: This is a standardized value, which is obtained from sample data. The t-test is used in conjunction with the F-test to determine the reliability of the null hypothesis. In this regard, the t-test helps a researcher to compare the results of the null hypothesis and the researcher’s data successfully. The value also helps in the computation of p-value when the null hypothesis ought to be rejected. The t-test for the above model is 4.788. The t-test indicates that the null hypothesis should be upheld. It is denoted by: The explained sum of squares represents the total sum of squares of deviation from mean value, of various predicted values. In this regard, high values of the sum of squares indicate reliability of the model used for statistical analysis. It is denoted by: The demand for money is based on the function of money, which include medium of exchange and store of value. This implies that people

Power and Responsibility Essay Example for Free

Power and Responsibility Essay In an altruistic sense, the burden of responsibility lies in the person making a decision for the a group of people as a whole and the consequences of such decisions or actions is solely limited to the person who made it. Even though a decision has been made in general to serve the people, the consequences still has to be faced. This does not change with an individualistic point of view wherein a profession that requires high standards in order to perform well needs a greater sense of responsibility for choice. A news writer or reporter who reports unverifiable or fallacious facts can easily retract statements in order to suit journalism rules. But when a doctor makes a mistake, people die. There is no difference with regards to the degree of responsibility a person since all professions must possess a deeper sense of responsibility. In the context of utilitarianism however, the concept is aimed for the welfare of persons as a whole in achieving a desired end. Applied in an individualistic view, responsibility lies with choice and a deeper understanding or personal morals and overall ethics. Utilitarian views are also consistent with consequentialism wherein an action may be considered morally right if it contributes more on a favorable consequence rather than a bad one. In this sense, moral values are then based on a good purpose or outcome. Thus the responsibility of an individual relies on the outcome itself and it may only be considered as morally correct when it serves the purpose of the greater good. Although journalism and health are professions that has corresponding moral and ethical systems, utilitarian views present a morally favorable principle wherein actions are guided by the responsibility of doing a good job not only to avoid moral and ethical problems but also in achieving a contribution to the overall utility or good and a drive in achieving excellence.

The Study of the Affects of Long Term Agruculture on the Soils of Europ

The Study of the Effects of Long Term Agruculture on the Soils of Europe 1. Introduction Soil, like iron, is a natural resource. Just as iron is mined from the earth, soil is mined for its nutrients by farmers across the globe. What most people don't realize is that like iron, soil is a non-renewable resource. Soils form naturally at rates of 0.5-0.02 mm/yr, whereas the average human-induced erosion rate is 2.0 mm/yr in the U.S.(Yassoglou, 1987). These numbers reflect the dire predicament of soils around the world, and demand answers to questions such as: What causes the degradation of soils? What role have humans played in the deterioration of soils? How much more abuse can the soil withstand? Due to the lengthy history of agriculture in Europe and the Mediterranean, these areas might provide insight into the answers of these questions. 2. Is there a problem of soil degradation in Europe? 2.1 Factors that degrade soils Soil degradation as it pertains to agriculture, refers to a deterioration in at least one of the five soil qualities: volume, structure, organic matter and/or biological activity, chemical composition, and fertility. Of the many processes that lead to the deterioration of these qualities, erosion is the most prevalent and pernicious. Erosion contributes directly to the degradation of all five qualities, and is indirectly involved in other processes of soil deterioration (Yassoglou, 1987) . Due to its importance as a factor of degradation, and the limited scope of this paper, erosion will be the focus of this inquiry. 2.2 Variables that affect soil sensitivity to erosion Soil sensitivity is dependent upon the initial state of the soil following pedogenesis, influxes of material, and the... ...(Morgan,1987). Further study could be pursued in the effect of degrading influxes on single soil properties. A complete study of soil degradation within the European Community as a whole should be done, as well as adopting a set of universal standards for measuring soil loss (Yassoglou, 1987). An interesting question to pose at this point is " If soil degradation is such a problem, why hasn't productivity been adversely affected?" The irony is that the same technological advances that increase soil degradation , increase actual productivity of the farm. Fertilizers, pesticides, and machinery all increase yields per a given area, and it is these factors that have prevented an agricultural crisis in Europe. In essence, we are running our own experiment on the soil, to see if our technology can outrace its destruction of the very foundation upon which it is built.

Howard Schultz and the Starbucks Company

Maln Problem Statement After analyzing all aspects and factors, the main problem statement found for this case study is as follows: â€Å"The rapid and over expansion plan of Starbucks store- owned outlets to capture the maximum market share has lead to many problems† As stated above, Starbucks is facing the problem of fast and over expanding of its outlets as the company tries to gain as much market share and opportunities as possible.This, however has led to many problems such as cannibalization of usiness through clustering and low net Income margin despite achieving record sales and revenues. The problem is further complicated by other problems such as Insistence of the company to store-own outlets outside the North American region and increased number of employees at Starbucks. 3. 0 Focus Expansion Only on under-served Countries and Locations One of the alternative strategies that could help to solve the main problem Is to change the Starbucks policy on outlet openings.In this strategy, Starbucks should identify countries or locations where the company has the least presence and oothold; choosing to open outlets only at these locations while stop outlet openings in areas where the company already has established itselt. For example, Starbucks should look into the China and South Korea market as there are currently only 9 outlets and 1 outlet of Starbucks In those locations, respectively. 3. 2 Allow Another strategy is to allow the franchising of the Starbucks brand to locations outside the North American market.

The events regarding the Panama Canal as discussed in David McCullough’s The Path Between Seas allowed an impressive assertion of American power--the likes of which had never before been displayed. In it’s rich history, this novel offers recollections of failure on France’s part, American strength overcoming Columbian resistance, and triumphant success of medical care and engineering. During the late 1800s, France was an undeniable force in the engineering world. It would turn out, however, that America was the country which would†¦show more content†¦As it would turn out, the French didn’t exactly accomplish what they had hoped. A major loss in funds due to gross misuse and bribery and large casualties rendered the project a total bust. Many of the early deaths were of the brightest engineering graduates of the time. Exaggerated claim s of false progress kept the money flowing into the project, but before long the fraud was exposed. Only two-fifths of the canal had been dug after the French spent 2 years longer than they’d intended digging. De Lesseps’s reputation was destroyed; all assets the French had gathered were sold to the Americans for a measly $40 million. America--unlike their predecessors in the task--would learn from prior mistakes and have much better luck with this undertaking, eventually accomplishing the task. America would even defeat Columbian resistance and assist in developing a new country. After settling the close debate as to where the American’s wished to build their canal and purchasing the area under the 1903 Hay-Herran treaty, the U.S. needed only permission to unearth the ground. Colombia wasn’t too fond of the idea and thus rejected all of America’s efforts. Negotiations with the country went quite poorly as well.
