Helping Students Find a Purpose for Their Education Essay Example for Free

Helping Students Find a Purpose for Their Education Essay It has been my observation that many of my best students became intrinsically motivated to put more effort into their education after they have decided on a career purpose. A work or career purpose or mission answers the following question: How do I want my career to benefit others? It is also important to identify who (the population) we want to benefit. An example of a work purpose statement is, â€Å"I want to help those who are sick or injured to heal and rehabilitate. † This statement does not contain a career title, but it provides guidance for exploring a variety of careers that can fulfill this purpose. For example a student with this purpose could explore a variety of careers such as nurse, doctor, physical therapist, nutritionist, athletic trainer, fitness trainer, engineer or inventor of products for persons with disabilities, etc. The career that they choose will depend on their capability and willingness to acquire the necessary skills, education, training and credentials. Ideally the career choice will be one that uses their best talents and is one they will enjoy doing. Do you ever share with students why you chose to work in the field of education? Students need to learn about different careers from adults who work in different career fields and to hear what motivated them to make their career choices. I teach college success courses and I used to wait until the end of my courses to get into career development, exploration and planning. Students did not think about a career purpose until the last week or two of my courses. Recently I started covering these ideas in the second week of my courses so that students would have a clear direction for their education much sooner. Having a career purpose can make their education relevant and is likely to generate the intrinsic motivation to study and learn. Students need to be provided with opportunities for career guidance from counselors, teachers and professors in high school and college. You do not need to be teaching college or career success courses to do this, but can weave in a few questions and ideas into other courses. Here are a few questions you can ask your students so that they can begin a process of self-reflection about their career purpose: 1. What purpose do you want to accomplish in your career? 2. What benefits do you want others to receive as a result of the work you do? 3. What specific populations of people do you want to help? 4. How do you want to contribute and make a positive difference for others? 5. If you were wealthy and chose to work what would you do? 6. What problem or need in the world would you most like to fill or solve? 7. If you knew you could not fail what type of work would you do? 8. What are some natural talents you would like to develop and use in a career to fulfill your work purpose? When we expect students who lack self-knowledge and a work purpose to choose a major and career, we are putting the cart before the horse. Identifying a purpose first will guide students into best career choices. If we help students to determine an appropriate career goal then they will also have a purpose for pursuing a good education

Igniting Flammable Liquids with Cigarettes

Igniting Flammable Liquids with Cigarettes Cigarettes seem like a probable ignition source for flammable liquids. Cigarettes have been blamed for the cause of many fires, far more than they should. But Cigarettes are more than tobacco wrapped in paper. They are in fact carefully engineered to burn in a certain way Cigarettes vary considerably from brand to brand in their burning characteristics. Modern cigarettes contain an engineered chemistry of additives to control the burning rates and moisture content of the tobacco and paper and anyone who has been a smoker knows the fact that manufactured Cigarettes go on burning when not being puffed. This spares smokers the trouble of lighting up again unlike with rolled up cigarettes and Cigars where the smoker has to keep smoking for the combustion of the tobacco to remain lit. This is good for the cigarette companies and pays off in higher sales from cigarettes. So yes this does mean that a cigarette rolling off onto a mattress or into the crack of a sofa can smoulder undetected f or 30 to 40 minutes before bursting into flames. Smouldering is a form of flameless combustion which can occur in materials capable of charring. Smouldering can occur at very low oxygen concentrations then proceeds at a very slow rate before flaming occurs. This makes people understand the real hazard of manufactured cigarettes. But that is found out through the visual fact of witnessing a cigarette stay lit and burn. So people will believe most of what they see as fact, but when many people sit down in their local theatre to watch the latest Hollywood movie they usual see the spectacular visual effects of a character throwing a lit cigarette on to a puddle of fuel and watching a large fire ball appear before their eyes which causes an amazing explosion. Igniting puddles of petrol for example with cigarettes in movies is a common device. The character takes a few puffs and tosses the glowing cigarette in the puddle. Immediately the petrol ignites. But Experiments with flammable gases and vapours have shown that many of the most commonly-encountered substances, including methane and petrol vapour, were not ignited by a lighted cigarette[1] So Petrol vapour cannot normally be ignited by glowing cigarettes, a fact which has been verified by many experiments. Cigarettes are rather uncommon as the source of ignition for a successful structure fire. If they are set to ignite liquid flammables, they will almost certainly fail[2] This paper looks to answer why a lighted cigarette when tested against the ignition of common flammable vapours such as petrol fail but other more volatile liquids tested are capable of ignition. Previous work carried out on cigarette ignition, related research in this field of combustion and ignition of flammable gases and liquids will be studied and researched to give the author a better understanding of the fallacy that a lit cigarette can be a danger that can readily ignite flammable liquids or gases. But not to underestimate the potential danger of such an ignition source in circumstances where many factors can come together to form self sustained combustion. Flammable substances and liquids are used for a wide variety of purposes and are commonly found in the home. Petrol is the most common, but there are other flammable and combustible liquids and gases used Table shows other flammable liquids commonly found around the home Lighter fluid Oil Propane Butane Aerosol Cans Diesel fuel Wood preservatives Kerosene White spirits Flammable materials found in the gaseous form will burn whenever mixed with the proper amount of air and properly ignited. A flammable liquid in its liquid state will not burn. It will only ignite when the vapours from the liquid evaporate in air. All flammable liquids give off vapours that can ignite and burn when an ignition source is introduced. Flammable liquids require an initial energy input to produce an air/vapour mixture within the limits of flammability (niamh mc daid) Ignition is the transition from a nonreactive to a reactive state in which external actions lead to thermo chemical runaway followed by rapid transition to self sustained combustion The usual conditions for ignition are given by a 3t rule of thumb. The three Ts stand for: Temperature. Must be high enough to cause significant chemical reactions and/or pyrolysis Time. Must be long enough to allow the heat input to be absorbed by the reactants so that a runaway thermo chemical process can occur Turbulence. Must be high enough so that there is good mixing between fuel and oxidizer and heat can be transferred from the reacted media to the unreacted media (cite the book) Ignition will occur when the process of a rapid exothermic reaction is started, which then gains momentum and causes the fuel to undergo change. When a flammable liquid is poured or spilled on a surface it is the vapours that are actually ignited. Vapours from liquids are what directly support the flame. To understand how volatile certain flammable liquids are it is useful to be familiar with the terms used to describe their chemical properties. Vapour density This is a property of a vapour that predicts its behaviour when released in air. when calculating the vapour density of a liquid fuel the molecular weight of gas of the vapour by that of air in normal conditions. (approx 29) (niamh mc daid) Flash point The flash point is the lowest temperature at which a liquid fuel will produce a flammable vapour. A liquid fuel must be able to generate a vapour in sufficient quantity to reach that lower limit in air before it can burn. This flash point is measured in two different ways, first being a closed cup measurement and the latter being an open cup. Flammable ranges Petrol has a narrow flammable range. Thus petrol vapour mixed with air has a lower flammability limit of just over 1% and an upper limit of 6% by volume petrol vapour in air, at normally encountered temperatures. (hollyhead) Flammable range refers to the percentage of a flammable liquid in its gaseous state to air to create an explosive mixture. Mixtures of flammable vapours with air will combust only when they are within particular ranges of vapour/air concentration. Outside of these limits the fuel-air mixture is either too lean or too rich to ignite (niamh mc daid) This varies with different flammable liquids. Gasoline has a flammability range of 1.4 to 7.6 percent. This means it will ignite when there is 1.4 parts of gasoline mixed with 100 parts air Ignition temperatures This is the temperature at which a particular flammable liquid gives off vapours and evaporates in air and therefore can ignite. Gasoline will ignite when a heat source or electrical spark of at least 853 degrees comes in contact with it. Natural gas (methane) needs an ignition temperature of around 1000 degrees Auto-ignition temperature (AIT) This is the temperature at which a fuel will ignite on its own without any additional source of ignition. (Niamh mcdaid) Fires will occur because there is high temperature introduced to an area in which there is a fuel-air mixture within its flammability range. There are so atmospheric factors that affect the Auto-ignition temperature e.g. Oxygen levels in the area of the mixture. But so long as the heat energy can be transferred from the source to the fuel ignition fire may result Flammability In Hollyheads paper he mentions the flammability of certain liquids e.g., kerosene, white spirit and diesel oil, which are flammable liquids with flash point temperatures above normal ambient. So therefore, an ignition source has to ignite not only the flammable mixture of fuel vapour but to generate this mixture in the first place by heating the bulk liquid. (hollyhead) Cigarette Components Modern manufactured cigarette comprise of different components. The components combined can affect the performance of the cigarette including the emissions of toxicants. In British manufactured cigarettes the tobacco used is Virginia. There are two other main types used in commercial cigarettes which are Burley and Oriental.   Each has different characteristics.  These tobacco types will also vary depending on their variety, in what environment they are cultivated and how that cultivation is carried out. The paper around the tobacco of commercial cigarettes in modified in different brands. It can be more porous in some brands so that the amount of air passing through the paper affects the yield of a puff. The more air that can pass through the paper the more the smoke constituents passing through the cigarette are weakened which then result in lower yields of various smoke products. Just as Baker describes when a cigarette burns, thousands of products are formed. They are distrib uted between the gas phase and aerosol particles which make up smoke. (baker) Modern commercial cigarettes are made with a filter. The filter is different on most brands. The way the filter is designed can affect the amount of filtration. Different cigarette brands can regulate the taste and smoking experience. Introducing vents in the paper surrounding the filter end can allow for dilution of smoke in lighter branding cigarettes. The bigger the length results in longer fibres and also the materials used for the fibres all play a part in making a certain cigarette different from other brands in the market. Figure shows the different components of a manufactured cigarette, how smoke moves through the tobacco and filter and how air moves through the paper (bat) Cigarette Combustion Many of the components identified in tobacco have also been identified in its smoke because they transfer in part from tobacco to its smoke during the smoking process. Many other identified tobacco components are not found in smoke because they decompose during the smoking process. (cite tobacco book) There has been work carried out to measure the burning temperature of a cigarette particularly those by Dr Richard R Baker have provided fundamental knowledge about the combustion/pyrolysis processes during smouldering and puffing of a cigarette. Dr Richard R. Baker has established the distributions of combustion temperature, gas velocity and key smoke constituents inside a burning cigarette. These experiments have become the foundation for the study of cigarette combustion. Dr Barkers paper studied the process of thermo physical concurrencies inside and around a burning cigarette (barker) Figure 2 shows combustion of a cigarette when being smoked (bat) The formation of smoke from a burning cigarette depends on a series of mechanisms, including generation of products by pyrolysis and combustion, aerosol formation, and physical mass transfer and filtration processes. Each mechanism, and their interactions, has a profound effect on the levels of chemical constituents in tobacco smoke. An enormous amount of research has been done on these subjects over the last 50 years. (barker) Figure 2 describes the two types of burning that take place when the cigarette is puffed. There is also a natural smoulder occurring between the puffs by the smoker. There are two main regions at the tip on the coal, namely the combustion zone A and the pyrolysis and distillation zone B. Combustible vapours are produced in zone B prior to ignition in zone A. During puffing, air is drawn into the cigarette through the paper and at the paper bum line. When a smoker draws on a lit cigarette, the temperature of the cigarette coal rises rapidly from its resting smo uldering temperature of around 600  °C.   Peak puff  temperatures at the periphery of the coal can exceed 900  °C  during a 35 mL, 2-sec puff. The high temperature inside the coal causes an increase in the viscosity of the air flowing through and a concomitant increase in the resistance to the draw of air through the coal.   This effect forces air to be drawn primarily into the periphery of the coal around the paper burn line, which causes more complete combustion in this peripheral region.   The depletion of oxygen due to combustion results in the formation of a region immediately behind the coal where the temperatures remain high enough for thermal decomposition of tobacco (the pyrolysis/distillation zone).   Large amounts of volatile and semi-volatile smoke constituents are produced in this region. A small amount of air is drawn in along the tobacco rod through permeable cigarette paper and smoke temperature decreases rapidly to produce a supersaturated aerosol. The smoke thus formed during a puff is subjected to filtration by the remaining tobacco rod and cigarette filter, as well as dilution by any filter ventilation holes. Some proportion of the light gases (such as CO) will diffuse out of the highly permeable cigarette paper. The smoke that leaves the mouth end of the cigarette is called mainstream smoke.   Between puffs, hot smoke escapes from the top of the cigarette and forms the sidestream smoke. In the authors research for this paper the general opinion that cigarettes are the cause of fires is truthful, as there is no question that many fires are started by cigarettes and the careless smoker is usually the reason for the high number of fires originating from smoking cigarettes. Despite advances in the fire retardant foams in furnishings and mattresses, smoking in bed remains a threat to the safety of people. But it is a common occurrence to hear theories about how smoking caused a fire when the alleged ignition would not have been successful under certain circumstances. No one combustion parameter alone can be used to explain why gasoline (petrol) vapour and methane are not ignited by cigarettes whereas hydrogen and carbon disulphide are. In fact, the parameters themselves are inter-related and taken as a whole can express the propensity of a substance to react with oxygen to form combustion products. This is directly related to the ease with which chemical bonds are broken to lead to the formation of the more stable products of carbon dioxide and water, which result from the combustion of most of these fuels. hollyhead Recent tests by the ATF Fire research Laboratory involved contact of burning tobacco cigarettes of different brands with petrol vapour from a pool at room temperature. A total of 137 attempts were made using both smouldering and actively drawn puffs with no ignitions observed. De haan Tests have shown the oxygen levels in cigarettes in the vicinity of combustion to be very low and carbon dioxide levels to be very high, both factors reducing the chances of vapour ignition The conditions in the combustion zone of a cigarette, which is deficient in oxygen and rich in hydrogen and carbon dioxide, together with the rapid and efficient tobacco-oxy- preparation of the oxygen reaction conspire to allow only the most reactive of substances to be ignited, and result in flame propagation to the vapour air mixtures outside the cigarette coal. Repeated attempts to cause explosions by inserting a lit cigarette into an explosive fuel vapour-air mixture have resulted in failure over many experiments. Hollyhead The residence time of airborne vapours in the cigarette being puffed is so short that there is not enough time for any but the most reactive species to ignite. The fuel elements in a commercially manufactured cigarette is such that quenching distance of all but most reactive gases is not exceeded, suppressing any sustained ignition. Experimental evidence and consideration of the cigarette combustion process, alongside ignition parameters of substances, show that mixtures in air of petrol and methane are not ignited by a lighted cigarette. It is very likely, therefore, that many fires have been wrongly attributed to a lighted cigarette; such a cause fire can often be the refuge of the uninitiated No Smoking regimes at chemical plants, oil gas installations and indeed petrol filling stations is, therefore, not in vain. Although a cigarette may not be an immediate problem, the lighted match or cigarette lighter flame used to light it, certainly could Occasionally contaminates or faults from the manufacture of the cigarettes, may it be in the tobacco filling or paper can cause some brief tiny flames. Given the right conditions and such an atmosphere where there is a fault and a perfect fuel-air mixture. Such flames would be a suitable ignition source. So even though many tests have proved that it is virtually impossible for a lit cigarette or cigar to ignite most flammable vapours, this could ensure the ignition of a fire, explosion or both. In study for this paper the author came across a message board where a guy was irate at the fact he seen another person smoke a cigarette on the fore court of a filling station. To his dismay when confronting the person in question about the stupidity of his action he promptly got the reply that cigarettes dont lit petrol, I seen it on myth busters. Goes to show that what some people see on Television is believed as fact, just like in the Movies. Some things will never change[1] 1. www.wikilaw3k.org/forum.

Climate Change Policy in the US

Climate Change Policy in the US Climate change to many is a â€Å"hoax† or a daydream, but to others it’s reality. Global warming is the rise of earth’s temperatures through carbon dioxide, air pollutants and greenhouse gases that are collected and trapped in the atmosphere. The pollutants would normally travel to space, but they trap the heat and cause the earth’s temperature to rise. Due to global warming, California has been in a long-going drought, icebergs in Antarctica are melting at a more rapid pace, and has caused disruption in marine-life. EPA, the United States Environmental Protection Agency, and the National Center for Policy Analysis has discussed the problems and solutions that the government and citizens of the world can help the earth in its stop to global warming. Ten of the policies being discussed are to reduce greenhouse gas emissions, increase energy efficiency, reduce air pollutants, and much more. The ten policies are: Eliminate all subsidies for fuel use, reduce regulatory barrier to new nuclear power plants, reduce wildfires through Alternative Forest Management, liberalize approval of biotechnology, repeal the National Flood Insurance Program, increase use of toll roads with congestion pricing, remove older cars from the road, reform air traffic control systems, remove regulatory barriers to innovation, and encourage breakthroughs in new technology. The many organizations who wants to inform the world of global warming has fought hard to give the attention that it needs and ways that humans can prevent it. Organizations such as the EPA and the NCPA have given factual debate of global warming and the serious outcomes it could bring and is bringing to the earth. The major debate of global warming policies is the costly measures it will take to protect the earth. There is also debate on if humans contribute to the issue of global warming or not. Many argue that humans can’t have any contribution to global warming, and others disagree. Either way if people believe that global warming is a hoax or not, we as humans should take the initiative to keep the earth clean and green. In 2016, President Obama visited Honolulu, Hawaii as his final family vacation as the president. During his visit, he noticed multiple things that were out of the ordinary for such a place as Hawaii. â€Å"What makes climate change difficult is that it is not an instantaneous catastrophic event. It’s a slow-moving issue that, on a day-to-day basis, people dont experience and don’t see,† says Barack. He also mentions how it is the greatest long-term threat facing the world, as well as a danger already manifesting itself as droughts, storms, heat waves and flooding. (Landler, 2016) President Obama wanted the debate of global warming to be heard before the end of his term. Obama presented ideas to cut planet-heating emissions in the United States. Since his call of awareness, he has been ridiculed by republicans and supported by democrats. Republican, democrat politicians and even economists believe that global warming is a hoax and that Obama is abusing his power a nd this decision could cause harm to the economy Obama said, â€Å"When you see severe environmental strains of one sort or another on cultures, on civilizations, on nations, the byproducts of that are unpredictable and can be very dangerous. If the current projections, the current trend lines on a warming planet continue, it is certainly going to be enormously disruptive worldwide.† Obama’s stance on the state of global warming has yet to change, and would be likely to never change. In 2008, the presidential race between McCain and Obama global warming was brought into debate. They both held the same stance on global warming; believing that it’s caused by humans and Congress should enact legislation to cap greenhouse gas emissions and force polluters to buy and trade permits that would slowly lower overall emissions of climate-warming gases.  (Davenport, 2016) Obama’s cap and trade bill failed through was blocked by senators from the democratic and republican parties in 2010. In the same year, the Tea Party clutched the cap and trade bill as a defense to politics/ the presidency. A year before that, the attempt to construct a United Nation climate change treaty in Copenhagen failed as well. Data proved that U.S. citizens and politician’s opinion on global warming was not the same as President Obama’s, and the discussion of global warming/ climate change fell into shambles. â€Å"There is the notion that there’s something I m ight have done that would prevent Republicans to deny climate change,† Obama said. Republicans, such as Senator Lamar Alexander of Tennessee, were willing to compromise to a more limited climate bill that would restrict emissions only from power plants (Landler, 2016) but Democrats could not agree to such a bill as that. Republican Alexander mentioned, â€Å"The White House wanted 60 votes on climate, and they weren’t interested in Republican votes. Now it’s back to power plant only. The lesson here is that if people who want a result would be a little bit more flexible, they might actually get one.† In Obama’s second term, he took the initiative to cut through Congress with the discussion of global warming/ climate change. Obama and his team establishes the Clean Air Act of 1970 that gives the Environmental Protection Agency (EPA) the authority to issue regulations on dangerous pollutants. (Davenport, 2016) Obama revealed the Clean Power Plan: a se t of Clean Air Act rules that would end several coal-fired power plants. Many critics imposed that Obama’s plan would damage businesses who flourish on coal-fired power plants. He responded with, â€Å"What we owe the remaining people who are making a living mining coal is to be honest with them, and to say that, look, the economy is shifting. How we use energy is shifting. That’s going to be true here, but it’s also going to be true internationally.† Fast forward to 2017, President Trump has dismantled Obama’s engagement to the stop of global warming/climate change. He has ordered the federal government to retreat from the battle against climate change proposed by Obama destroying the policies that made America a global leader in curbing emissions. â€Å"My administration is putting an end to the war on coal. I am taking historic steps to lift the restrictions on American energy to reserve government intrusions and to cancel job killing regulations,† Trump explained. Following Trump’s order, the government will no longer apply the â€Å"social cost of carbon† (Halper, Trump Orders Government to Dismantle Obamas Climate Change Policies , 2017) allowing for factories, power plants, and  (Halper, Trump Orders Government to Dismantle Obamas Climate Change Policies , 2017) etc to continue to plant harmful gases into the atmosphere. Trump has called for the attention of global warming and climate change to be cut down â€Å"because global warming is a hoax created by China†. Officials have stated that the order instructed from Trump would delete all of Obama’s, EPA, and other environmental agencies work. It has been said that the policies created by Obama and others would cause economic catastrophe. Environmentalists have damned the changes being brought forth by Trump mentioning that the cutback of climate change policies will put humans and the earth at risk, regardless of how long it will take for everyone to â€Å"see† climate change. â€Å"Obama created a labyrinth of rules and orders and regulations to cement his agenda across practically every agency,† Tom Pyle, president of the American Energy Alliance mentioned. Many of the members in environmental agencies agrees that Obama’s plan was for the benefit of human life on this earth and Trump is doing everything in his power to eliminate Obama’s policies.

Hamlet Rosencrantz and Guildenstern :: Shakespeare Hamlet

Hamlet Rosencrantz and Guildenstern This procrastination cannot be due to an instinctive and fastidious repugnance to killing, for Hamlet kills Polonius, and Laertes, and in the end the King himself; and he dispatches Rosencrantz and Guildenstern to their doom with true alacrity. Whence then does it come? The answer will be found by examining all these cases. And before them all, let us look at those two lines in 1.4. unhand me gentlemen, By heaven I'll make a ghost of him that lets me! It is one of the key points in the drawing of his character. When it comes to doing what he is determined to do, he will not hesitate to kill even his closest friend, for Horatio is one of the gentlemen whom he threatens sword in hand. Hamlet's spontaneous tendencies are therefore essentially individualistic; and, the point must be emphasized, not even death of others, if need be, will stand in his way. This the Hamlet whose behavior towards Rosencrantz and Guildenstern we are now to study. They were his friends, and we know from his mother that he had much talked of them and that two men there are not living To whom he more adheres. The two young men receive from the King a commission which, whatever the King's secret intentions may be, is honorable. Hamlet, the King in fact tells them, is not what he was. The cause of the change "I cannot dream of." Therefore, I beg you so by your companies To draw him on to pleasures, and to gather So much as from occasion you may glean Whether aught to us unknown afflicts him thus That opened lies within our remedy. Guildenstern's words show that the two young men understand their work in an irreproachable way: Heaven make our presence and our practices Pleasant and helpful to him. They enter upon their new duties at a later stage in the same scene. Cordial and lighthearted, the meeting of the three young men leads to some fencing of wits on ambition; for Rosencrantz and Guildenstern, who know nothing about King Hamlet's murder, naturally assume that the trouble with Hamlet is frustrated ambition (and so in part it is): Hamlet, of course, parries, and as he tries to move off, his two companions, in strict obedience to their master, the King, say: "We'll wait upon you.

Solar Cookers :: Essays Papers

Solar Cookers Jewish families celebrate Passover to commemorate the freedom and exodus of the Israelites (Jewish slaves) from Egypt during the reign of the Pharaoh Ramses II. When the Pharaoh Ramses II freed the Israelites, they fled so quickly that there wasn't time to bake their breads. Instead the Israelites packed the raw dough, which they quickly baked in the hot sun into hard crackers called Matzohs as they fled through the desert. The exodus of the Israelites took place over 3000 years ago, but the Israelites were not the first to harness solar power for cooking, neither were they the last. Solar cooking has had a long rich history and has important implication for the future. Solar cooking is an important link in understanding the sun’s power, is a sink of innovation and technology, is widely applicable around the world, has social, economic and ecological benefits, and is the answer to some of the world’s biggest natural resource shortages. Although, solar cooking is an ind ustry that has yet to be revolutionized into an efficient home appliance, therefore, there are many avenues for innovation and technological advancement to be explored. Horace de Saussure coincidently created the first solar box cooker, although, because cooking food was not his objective he failed to revolutionize the solar cooking as an efficient home appliance. Horace de Saussure, â€Å"set out to determine how effectively glass heat traps could collect the energy of the sun.† Horace de Saussure placed five consecutively smaller open bottomed glass boxes within each other on a black table, in which he placed a piece of fruit. When this miniature five walled green house was exposed to the sun, each consecutive glass chamber trapped warm air and thermal radiation, which are by products of light energy being turned into heat. Consequently the innermost glass box became the hottest, a recorded 189.5 degrees Fahrenheit and Horace de Saussure successfully cooked fruit within this box. Cooking was only an experiment used by Horace de Saussure to understand his greater goal, which was how effectively glass heat traps could collect the energy o f the sun. Although, Horace de Saussure realized the practical application of his heat trap. Horace de Saussure stated, â€Å"someday some usefulness might be drawn from this device . . . [for it] is actually quite small, inexpensive, [and] easy to make.† Horace de Saussure was correct in stating that solar cooking is useful, but contrary to his advice the solar cooker failed to be revolutionized into an efficient home appliance.
