Homeless What has been done to Essay Example For Students

Homeless What has been done to Essay Homeless: What has been done to decrease the problem? One of the largest growing concerns in Toronto is the constantly increasing number of citizens who are finding themselves living on the streets. With the decrease in the number of available jobs, the population of homeless people has literally boomed. My questions are not as simple to answer as they may appear. Why is a large portion of our community forced to live on the streets? What has be done to decrease the problem? These are the questions I will confront in my essay. With the economical wealth attributed to the name Canada, one would have to wonder why there is a homeless situation at all. This problem is especially evident in Canadas wealthiest city, Toronto. When it comes to the affairs of the people, it is the government who should intervene. When I look at what the government has done with regard to the homeless problem, I have to doubt that everything is being done to eradicate it. The United Nations implemented a universal declaration of human rights. Article 25 Section 1 of this declaration states: Everyone has the right to a standard of living adequate for the health and well being of himself and of his family, including food, clothing, housing, and medical care and necessary social services, and to the right to security in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond his control. This is a step in the right direction. However, this is not enough. These rights are subject to the discretion of the government of the country who decides to obey these universal rights. How much is adequate? The government, both at the federal and municipal levels, is currently working on new spending cuts. These cuts also include spending on welfare, unemployment and social services that are geared towards helping the homeless. Spending cuts can be seen as a necessity to maintain the country economically, but the reason for having a government in the first place is to take care of the people. How can this be done when money is being taken away from those services that are necessary to uphold this obligation? Simply put, it cannot. Those obligations are served by nonprofit organizations who depend on government grants to maintain a standard of care for those who need the services. The blame cannot be placed only on the government. Such a system of assistance depends on its beneficiaries to be honest and have some integrity. Many recipients of these services attempt to cheat the system. With no will to search for work many of these recipients remain at home and reap the benefits of their weekly cheques. This causes the government to create other services to control the amounts of money being distributed to those people. This process is costly and would be unnecessary if all of the recipients decided to take an honest approach to this service. What can the government do to decrease the homeless population? Although there is no quick and easy answer to solve this difficult problem, Toronto has the means to attempt economical ways to research and come up with ideas to solve it. Here in Ontario we have many excellent universities and colleges with equally excellent students who are taking courses in the political sciences. If the government were to cooperate with these universities and colleges and have them work in conjunction with the current research groups, then the answer to decrease the homeless population would be effectively answered. The government would encounter little expense and at the same time give the students a chance to implement what they are learning into real life situations. Everyone benefits from this idea and there are no losers. .u21a2e5cd535e2f53a76c8a0cdecd0cc4 , .u21a2e5cd535e2f53a76c8a0cdecd0cc4 .postImageUrl , .u21a2e5cd535e2f53a76c8a0cdecd0cc4 .centered-text-area { min-height: 80px; position: relative; } .u21a2e5cd535e2f53a76c8a0cdecd0cc4 , .u21a2e5cd535e2f53a76c8a0cdecd0cc4:hover , .u21a2e5cd535e2f53a76c8a0cdecd0cc4:visited , .u21a2e5cd535e2f53a76c8a0cdecd0cc4:active { border:0!important; } .u21a2e5cd535e2f53a76c8a0cdecd0cc4 .clearfix:after { content: ""; display: table; clear: both; } .u21a2e5cd535e2f53a76c8a0cdecd0cc4 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u21a2e5cd535e2f53a76c8a0cdecd0cc4:active , .u21a2e5cd535e2f53a76c8a0cdecd0cc4:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u21a2e5cd535e2f53a76c8a0cdecd0cc4 .centered-text-area { width: 100%; position: relative ; } .u21a2e5cd535e2f53a76c8a0cdecd0cc4 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u21a2e5cd535e2f53a76c8a0cdecd0cc4 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u21a2e5cd535e2f53a76c8a0cdecd0cc4 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u21a2e5cd535e2f53a76c8a0cdecd0cc4:hover .ctaButton { background-color: #34495E!important; } .u21a2e5cd535e2f53a76c8a0cdecd0cc4 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u21a2e5cd535e2f53a76c8a0cdecd0cc4 .u21a2e5cd535e2f53a76c8a0cdecd0cc4-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u21a2e5cd535e2f53a76c8a0cdecd0cc4:after { content: ""; display: block; clear: both; } READ: Marion Barry Essay In conclusion I think that our homeless problem could eventually be rooted out entirely if everyone were to take part in the care of their fellow neighbour.

A Farewell To Arms - Response Essays - A Farewell To Arms

A Farewell to Arms - Response A Farewell to Arms [If The Sun Also Rises was one of the best books I have ever read, then A Farewell to Arms is Truth. I simply cannot believe that these books existed so long without my knowledge of how grand they are. I consider myself to read constantly, more than almost anyone I know, literature and simple, and here in less than a month I read two books that are undoubtedly among the best I have encountered. How many other good books exist that I have yet to read? Am I really a reader? Will I ever finish them all? What will I do if I tire of reading?] When I finished FTA I was of course stunned by the death of Catherine and the baby and Henry's sudden solitude. "What happens now?" I felt, as I so often do when I finish a book that I want to go on forever. This is infinitely more difficult with a book that has no conclusion, and FTA leaves a reader not only emotionally exhausted but also just as alone as Henry and with nowhere to go. The entire work was aware of where it was goin g and what was going to happen next, and then to stop the way it did was unfair. Now, I've read enough essays while deciding which would be the topic for my class presentation that I know many people see that the unfairness of life and the insignificance of our free will are apparently the most important themes in the book, but I don't agree. I also don't agree that it is a war story or a love story. Exactly what it is, though, is not clear to me. Can't art exist without being anything? "There isn't always an explanation for everything." War and love are obviously important themes in the book, and the relationship between the two is explored by Hemingway and, somewhat, by Henry. In the first two Books we are in the war and the war is overwhelming. In the last two Books we are in love. And, just as the first two Books are peppered with love in the time of war, the last two Books are tinged with war in the time of love. The third Book is the bridge between the two 'stories' and it is not surprising that it centers on the escape. It is during the escape that Henry resolves that he is through with the war (a war in which he really has no place) and decides that all he wants is to be with Catherine. Until the third Book Henry doesn't seem to be agonizingly concerned with matters of right or wrong in the war and it seems, in fact, separate from him. Even when he is injured it doesn't appear that he is really a part of the war which surrounds him. He maintains a distance from it and this distance isn't really closed until Aymo is killed by his own army, he discovers that Bonello is only staying with him out of respect, and he is almost killed as a spy. After this he resolves to desert the army and be reunited with his love, Catherine. Henry is no dummy and he could easily tell that everything was not all correct with Cat, which leads to the question of his love for her. You must admit that Cat is a bit...well... flaky when they first meet. She loses that persona soon enough, although I couldn't help but distrust her integrity until somewhere in the middle of the fourth Book. It is also difficult to believe wholeheartedly in his love for her until much later in their relationship, and it leaves me wondering if he is leaving his involvement in the war because of his unfailing love for Cat or if Cat and any feelings he has for her are just excuses to escape the insanity of the war he experiences in the third Book. When he is with Catherine, they are in another place, untouched by the war, both symbolically (in the tent of her hair) and literally (in Switzerland). [It seems like I don't ever say anything

How does the imagination of disaster (Susan Sontag) function in Essay - 1

How does the imagination of disaster (Susan Sontag) function in depictions of urban catastrophe in film I Am Legent' (2007) - Essay Example Susan argues that the film thrives on the sensuous connection with the audience through the arresting images and the immediacy of the experience as observed on the screen. The author traces the main stages of development of the sci-fi film in terms of the emergence of a situation that disturbs harmony, to the stages of disbelief, tragedy, threat, destruction, feelings of vulnerability, and the heroic antics of a lone actor who eventually designs some kind of remedy that prevails against the formidable foe. The main features in Sontag’s analysis are manifest in the post-apocalyptic film I am Legend, which was directed by Francis Lawrence with Will Smith featuring as the military virologist Robert Neville, the main protagonist (Lawrence, 2007). In the film, Neville finds himself facing the odds of a horrific destruction wrought by a scientific experiment gone awry leading to a virulent strain of a virus that has depopulated nearly 95 percent of the world population. Neville has to put aside his own pain of losing his wife and child and struggle to save his own life and the lives of the few surviving humans by developing an antidote that would rescue the infected and the few survivors. The task is daunting and the odds are nearly insurmountable for the lone hero but he has to endeavor to contain the horror. The film represents the good and bad of science in the sense that it captures both its threat to humanity and its near limitless potential to provide solutions to the same thre ats. Sontag argues that scientific films are mainly dominated by the theme of massive destruction (Sontag, 1966). The focus, she argues is the scale of destruction, which is usually captured on an enormous and shocking scale. Destruction is captured in grim details that involve the potency of powerful machinery, a determined destructive force, and great humanitarian suffering. Most of these films anticipate calamities and apocalyptic

Postmodernism in the Field of Anthropology Research Paper

Postmodernism in the Field of Anthropology - Research Paper Example The research paper "Postmodernism in the Field of Anthropology" states the postmodernism in the field of anthropology. Comprising the idea of this new practice, they do not anymore depend completely on the answers that have been given by the church or biblical canon, eminent intellectuals and scholars have provided with concrete theories so that they can account for the formation of the world and its dwellers. While differentiating between various concepts like humanism which was applied by Franz Boas and E.E. Evan Pritchard, did exist altogether with the method based epistemology of science, around 1980 a very concrete theory emerged which led to the systematic study of human life namely postmodern anthropology. The postmodern epistemology has been exempted from the similar fields like of symbolic and feminist anthropology, this constitutes the significance of our ethical responsibility, the importance of the relativity of our position it also deals with the consequent subjectivity it develops, and it by force challenges the aloof ideal of the uninfluenced view. The purpose of developing this field was to understand, examine and reason. To evaluate and draw conclusions about our ancestors and their lives. The postmodernist who is criticizing or critiquing on science usually has two formal interlinked arguments that is epistemological and ideological. Both of these are based on subjective approach. The initial debate that arises is that anthropology cannot be a branch of science. in accordance with the epistemogical approach and the reason is that basically the purpose of science is objectivity and a relatable conclusion. Secondly, the concept of objectivity is too vague and fantasized, therefore one relates to science in an ideological perspective, it tends to camouflage itself by supporting and voicing the rights of the suppressed class, women, ethnicities, etc. The universally recognized act of developing a scientifically indifferent view which was severely criticized by Clifford Geertz, who deviated from the universal formulations of prior anthropologists and carried on that features of culture, like religion, should be visualized and sorted by the meaning it contains, irrespective of what sort of reaction it may develop in the society. Culture is something which differs for everybody. It's how one takes it to be not something homogenous for all. As all humans perceive and adopt things differently therefore culture is then different within people living together as well. Feminist anthropology trails across the limitations of academia and changes the gathered research and makes it concrete. Fieldwork doesn’t only cover up the entire thing, it acts like a spark igniting the effort for better morality in culture as well as socially.(Salzman 2001). These joined principles of symbolic and feminist theories emerge as the basics that lead to postmodernism; it is a great combination of relativist epistemology and advocacy (Salzman, 200 1). When we take the initial one under consideration, a very essential point of this postmodern theory is the eager denial of science, a limiting tool within an powerful dominant class. The stress is laid upon that the symbolic and feminist anthropology that has been based on morality and subjectivity; hence, it negates the consumption of the empirical scientific method in best context that defines the authencity. (Heartney, 2001)Those who were working with the assumptions were not credited while now the room for the postmodern

The Robot Tree A New Ecofriendly Technology Environmental Sciences Essay

The Robot Tree A New Ecofriendly Technology Environmental Sciences Essay The paper deals with the concept of a synthetic tree called ROBOT TREE. The Robot tree has the potential to absorb carbon dioxide which is the major cause for the global warming. Although methane, nitrous oxide, ozone, fluorinated compounds also account for the global warming, carbon dioxide is the major gas which causes ninety percent of the global warming. The definition of global warming, causes and effects of global warming, the solution we propose, how the robot tree (synthetic tree) gives a solution to the effect and the feasibility of the synthetic tree are deeply discussed in this paper. This paper can act as a guidebook to know about the technology with its seeds and weeds and to get the importance of the technology in the approaching future. INTRODUCTION: We all know that forests are the treasures of our earth. But now, mankind himself has started to destroy forests -the treasures of our earth. By cutting trees, not only that the rainfall will be reduced, also the temperature will raise enormously, which results in global warming. This causes harm to the whole mankind. Thus the scientists are giving call to protect forest and save mankind. Research is going on regarding the issue. In our paper we propose an astonishing solution to save our earth from global warming.The greenhouse effect is being accelerated by releases of certain gases to the atmosphere that are causing the Earths temperature to rise. WHAT IS GLOBAL WARMING Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent. Over the last 100 years, the average temperature of the air near the Earth ´s surface has risen a little less than 1 ° Celsius (0.74  ± 0.18 °C, or 1.3  ± 0.32 ° Fahrenheit). Does not seem all that much? It is responsible for the conspicuous increase in storms, floods and raging forest fires we have seen in the last ten years, though, say scientists.    Their data show that an increase of one degree Celsius makes the Earth warmer now than it has been for at least a thousand years. Out of the 20 warmest years on record, 19 have occurred since 1980. The three hottest years ever observed have all occurred in the last eight years, even. 180px-2000_Year_Temperature_Comparison MAIN CAUSES FOR GLOBAL WARMING: Carbon dioxide, water vapour, nitrous oxide, methane and ozone are some of the natural gases causing global warming. CARBON DIOXIDE Ninety-three percent of all emissions Generating power by burning carbon based fossil fuels like natural gas, oil, and coal, decomposition, accounting for about one quarter of all global emissions. METHANE Twenty times more effective in trapping heat in our atmosphere 25 times as potent as carbon dioxide Agricultural activities, landfills. NITROUS OXIDE Agricultural soil management, animal manure management, sewage treatment, mobile and stationary combustion of fossil fuel, adipic acid production, and nitric acid production. OZONE Automobile exhaust and industrial processes. HYDROFLURO COMPOUNDS (HFCs). Industrial processes such as foam production, refrigeration, dry cleaning, chemical manufacturing, and semiconductor manufacturing. PERFLURONIATEDCOMPOUNDS (PFCs). Smelting of aluminium HEALTH AND ENVIRONMENTAL EFFECTS: Greenhouse gas emissions could cause a 1.8 to 6.3 ° Fahrenheit rise in temperature during the next century, if atmospheric levels are not reduced. Produce extreme weather events, such as droughts and floods. Threaten coastal resources and wetlands by raising sea level. Increase the risk of certain diseases by producing new breeding sites for pests and pathogens. Agricultural regions and woodlands are also susceptible to changes in climate that could result in increased insect populations and plant disease. The degradation of natural ecosystems could lead to reduced biological diversity. WHAT GLOBAL WARMING EFFECTS ARE EXPECTED FOR THE FUTURE? To predict the future global warming effects, several greenhouse gas emission scenarios were developed and fed into computer models. They project for the next century that, without specific policy changes Global mean temperature should increase by between 1.4 and 5.8 °C (2.5 to 10 °F). The Northern Hemisphere cover should decrease further, but the Antarctic ice sheet should increase. The sea level should rise by between 9 and 88 cm (3.5 to 35). Other changes should occur, including an increase in some extreme weather events. After 2100, human induced global warming effects are projected to persist for many centuries. The sea level should continue rising for thousands of years after the climate has been stabilized. We have weather up to 40 degree Celsius now. IMPACTS OF RISE IN MAJOR GREEN HOUSE GAS CO2: In air the carbon dioxide concentration should be approximately 330 ppm (parts per million).But due to environmental researchers the carbon dioxide content will increase as follows, 2025Æ’Â  405 to 469 ppm 2050Æ’Â  445 to 640 ppm 2100Æ’Â  540 to 970 ppm We have weather up to 40 degree Celsius now. It is expected that the weather will increase in Tamil Nadu as follows. In 2025 Æ’Â  0.4 to 1.1 degree Celsius In 2050 Æ’Â  0.8 to 2.6 degree Celsius In 2100 Æ’Â  1.4 to 5.8 degree Celsius SOLUTION WE PROPOSE: We all know that forests are the treasures of our earth. But, man started to destroy forests and the scientists are giving call to save forest. We all know that forests help to protect the earth from global warming. By cutting trees, not only that the rainfall will be reduced, also the temperature will raise enormously, which causes harm to the whole mankind. The research is going on all the time to save the mankind from global warming. Now, it has been found that robot trees will help to tackle the problem of global warming. In the air, the carbon dioxide content should be 330 ppm (part per million). Day by day it is increasing which results in global warming. WHAT IS ROBOT TREE The scientists are trying to make robot to perform various activities to reduce the physical and mental work of human being. The combination of nature and robots is called Robotany. The scientists Jill Coffin, John Taylor and Daniel Bauen are researching on robot tree. The robot tree does not look like our ordinary tree. The structures of the stem, roots and leaves are present in the robot tree. Does robot tree help to solve the problem of global warming? I have read in a magazine recently that the experiment done by the researchers at Madurai Kamaraj University on robot tree is successful. Hats off to them. It is really happy news. We have studied in history that the kings of olden days had planted trees on both sides of the road. In the same way we hope that all the roads will have robot trees on both sides in future to prevent global warming and save the earth. It is said that one robot tree is equal to 1000 natural trees. Each robot tree looks more like a giant fly swatter so as to remain as guards of mankind Klaus Lackner, a professor of Geophysics at Columbia University, is working on an interesting concept:   synthetic trees.   The idea is to reproduce the process of photosynthesis to capture and store massive amounts of CO2 gas. Nearly 90,000 tons of carbon dioxide a year, roughly the amount emitted annually by 15,000 cars, could be captured by the structure. Paired with a windmill, the carbon-capture tree would generate about 3 megawatts of power, Lackner calculates, making the operation self-sufficient in energy. synthetic_tree The scientists are trying to make robot to perform various activities to reduce the physical and mental work of human being. The combination of nature and robots is called Robotany. The scientists Jill Coffin, John Taylor and Daniel Bauen are currently researching on robot tree. HOW DOES A ROBOT TREE FUNCTION Just imagine a normal tree. A normal will have a root, stem and leaves. In the same way, the robot tree also has root, stem, branch and leaf like normal tree. Some plastic poles are fixed in the stem part and in between solar plates are fixed which act as leaves. In the big poles small holes are made and small poles are fixed. This will absorb carbon dioxide in the air. In the inside of big poles there will be calcium hydroxide liquid and the absorbed carbon dioxide will be dissolved in it. The solar plates produce current and pass current inside the stem, which will separate carbon and oxygen. Oxygen, hydrogen and vapour will come out. The carbon will act with water and become carbonic acid. The carbonic acid will pass down through robots and will be absorbed by the soil Once again. A sketch of the form and construction of A Tree for Anable Basin A new air extractor technology presented by Klaus Lackner, a professor of Geophysics at Columbias Earth Institute, offers something no other carbon capture technology on the drawing board has. Unlike conventional carbon capture and storage (also known as geosequestration), which absorbs C02 on-site (i.e. the affluent stream of emissions from power plants), air extractors absorb carbon dioxide from any location on the planet. This means that CO2 emissions can be captured from nearly all large-emitting sources-from stationary factories and power plants to cars and planes in motion. These synthetic trees can thrive in any location. synthetic trees A computer-generated image of Lackners synthetic trees. Synthetic trees dont exactly look like your average tree with green leaves and roots. Although the design is not finalized, Lackner predicts that the device would look more like a post with venetian blinds strung across it; a box-shaped extractor raised about 1,000 feet tall, adorned with scaffolding lined with liquid sodium hydroxide (commonly known as lye). When exposed, sodium hydroxide (lye) is an absorbent of CO2. So, as air flows through the venetian blind leaves of the tree, the sodium hydroxide will bind the CO2, sifting out cleaner, about 70-90% less CO2 concentrated air on the other side. Lackner estimates that an area of sodium hydroxide about the size of a large TV screen (a 20 inch diagonal) and a meter in depth could absorb 20 tons of CO2 a year. Paired with a windmill, a carbon-capture tree could generate about 3 megawatts of power. IS IT FEASIBLE The chemical process of using calcium or sodium hydroxide to absorb CO2 has been known for years but the question of whether it can be done in an affordable energy efficient manner has not yet been fully answered. Constructing and erecting the collector device is only 20% of the cost; the remainder of the cost involves prying the CO2 loose from the absorbent and storing it- an energy intensive process. The back of the envelope calculation of total cost supposes 3000 to 5000 rupees per ton captured, which is large as compared to the 1000-2000 rupees per ton on cost that proponents of a carbon tax or cap-and-trade scheme believe will stabilize atmospheric emissions of CO2. It may seem like too steep a cost to closely consider, but Lackner believes its worth looking at things that start out even five times too expensive . DEVELOPING CARBON CAPTURE AND STORAGE (CCS): carbon-capture-and-storage1 Despite common concern that CCS, and thus air capture too, will discourage our society from moving to clean energy alternatives. Fossil fuels are not running out anytime soon, and if we were to turn all of them into carbon dioxide, well have a climate catastrophe. We may run out of oil and gas; you can be skeptical of that. But we wont run out of coal. We either abandon fossil fuels immediately within the next 50 years or figure out a way to do CCS. As we head toward 450, 550, even 750ppm this century, environmental leaders are getting serious about carbon capture and storage. A 2005 IPCC report concluded that carbon capture and storage has the potential to reduce overall mitigation costs and increase flexibility in reducing greenhouse gases. Existing carbon capture technology can reduce CO2 emissions from coal-fired or natural-gas power plants by 80 to 90 percent, estimates the IPCC .energy efficiency and some renewables are cheaper now, but if the climate begins to tip out of control, then carbon capture and storage can provide a planet-saving insurance policy. BASIC CHEMICAL REACTIONS WITH ROBOT TREE: The reaction of sodium hydroxide with carbon dioxide (as carbonic acid) occurs essentially in two steps, first a reaction from carbonic acid to bicarbonate and then to carbonate. This is a simple acid-base reaction. CO2 is an acid anhydrite and NaOH is a base. So reaction gives the salt Na2CO3 and water another possible product is the salt Na2CO3 that is produced if a 1:2 ratio of CO2 and NaOH is used. A small percentage of moisture present in the absorbent material, (about 3%) is important. CO2 reacts with this moisture to form carbonic acid, CO2+H 2O->H2CO3 Which in turn reacts with the hydroxide to form the salt of carbonic acid, or sodium carbonate? The absorption of carbon dioxide is expressed as follows: The products of reaction are sodium carbonate and water. H2CO3 + NaOH -> NaHCO3 + H2O NaHCO3 + NaOH -> Na2CO3 + H2O DECARBITE: DECARBITE ® is an absorbing product. This product is sodium hydroxide carried on a silica base. The natural affinity of sodium hydroxide to acid gasses makes it a desirable material to use in the absorption of the acid gas carbon dioxide. The sodium hydroxide content in DECARBITE ® is high, approximately 90%, and accounts for the aggressive product performance and exceptional capacity for absorption of carbon dioxide. The sodium hydroxide content in DECARBITE ® is high, approximately 90%, and accounts for the aggressive product performance and exceptional capacity for absorption of carbon dioxide. The universally accepted Carbon Dioxide absorbent, DECARBITE ® is a consumable chemical absorbent. It is a specially formulated mixture of Sodium Hydroxide on to an inert silica carrier providing a surface area especially suited for the rapid, high performance and total absorption of CO2 on contact. EFFICIENCY: For the rapid or high performance quantative absorption of CO2 in the ppm range DECARBITE is color indicating, changing from greenish brown to white upon carbon dioxide saturation. The absorption of carbon dioxide removal or any acid gas using DECARBITE is a chemical reaction, not a physical one. Carbon dioxide reacts with the sodium hydroxide based absorbent and undergoes a complete chemical change. This change is irreversible; therefore the absorbent cannot be regenerated for reuse. This change is clearly perceptible and indicates when spent material is to be discarded. Occasionally, a condition known as channeling can occur when the gas flow finds holes or areas of least resistance and a channel is formed. The gas flow follows these channels through the absorbent defeating the purpose of scrubbing out the carbon dioxide. DECARBITE eliminates this problem in several ways; the silica binding to the sodium hydroxide keeps the particles from bonding in the presence of moisture which is formed as a byproduct of the absorption reaction. It also aids in preventing the absorbent to coalesce into a solid mass blocking gas flow and causing back pressure across the absorption bed. The association reaction of NaOH with CO2 is at least 40 times faster than NaOH + HCl at all altitudes below the Na layer. Na species will not affect stratospheric ClOx and O3 chemistry. The conversion of carbon dioxide to bicarbonate is complete at pH 8.3.Phenolphthalein can be used as a color indicator for the titration. CONCLUSION: Energy is really a place where more technology is absolutely necessary. Nearly one and half a lakh robot trees are enough for purifying carbon dioxide in the air for one year, approximately. One robot tree is said to have the capacity to absorb 90,000 tons of carbon dioxide every year. It is the amount of carbon dioxide released by 15,000 cars in one year. But robot trees will not help to bring rain. It will protect the earth from global warming. Cost 🙠 app) 10 feet robot tree-50,00 200 feet robot tree-5 lakhs. The cost of the robot tree may be high, but the cost of not having prominent technology for global warming may cost even higher. There arent that many large scale sources of energy could be tapped at the scale the world needs them. Hydro will never be enough, and neither will wind. Solar, nuclear, and fossil could be enough, but they all have flaws. If we dont place big bets on all three, we could find ourselves with none of them working, and well have energy crisis of unprecedented proportions. We have studied in history that the kings of olden days had planted trees on both sides of the road. In the same way we hope that all the roads will have robot trees on both sides to prevent global warming and save the earth. It is said that one robot tree is equal to 1000 natural trees.
