Maglev Wind Turbine and Solar Panel for Streetlight
Maglev Wind Turbine and Solar Panel for Streetlight Abstract:à This work describes the implementation of VAWT and solar panel for electricity generation from renewable energy sources that are wind energy and solar energy respectively. The VAWT worked on electromagnetism principle has suspension system of permanent magnets instead of ball bearing used in conventional wind turbines. The electrical energy generated by this hybrid system is then used for streetlight purpose. Keywords: Wind energy, Solar energy, Magnetic Levitation, VAWT, Savonius Turbine, Solar panel 1. INTRODUCTION The primary factor for survival of human beings is the energy. Everything what happens in the world is the expression of flow of energy from one form to another. Electric power is not available in many rural areas due to high cost of generation and distribution to small dispersed users. For electricity generation we have to greatly depend upon hydraulic and nuclear power plants. But due to their certain disadvantages like area compensation, high initial cost, availability of resources and also the pollution, there is need to rethink on some another renewable energy resources. Solar energy and wind energy are available abundantly all over the world with free of cost. These energies are harnessed by human beings for a long time and with the advanced technologies we can take their advantage to generate electricity. The potential of solar energy is 178 billion MW which is about 20000 times the worlds demand and the potential of wind energy is 1.6ÃÆ'-107 MW equal to magnitude of present energy consumption on the earth. The solar energy can be converted to electrical energy by photovoltaic cells. The kinetic energy of wind can be converted to electrical energy by wind turbine. As conventional wind turbine has certain disadvantages; vertical axis wind turbines (VAWT) are the alternate solution. The merits of VAWT are low initial and running cost, easy installation, less space acquired, capability to capture wind from any direction and elimination of ball bearings by the use of magnetic levitation technique. The advantage of these two renewable energy resources can be taken by making a hybrid system so we do not required depending on availability of any single resource. The electricity required for domestic purpose can be generated by unique combination of solar system and wind system. 2. LITERATURE REVIEW 2.1 Solar power The solar power where sun hits atmosphere is 1017 watts, whereas the solar power on earths surface is 1016 watts. The total world-wide power demand of all needs of civilization is 1013 watts. Therefore, the sun gives us 1000 times more power than we need. If we can use 5% of this energy, it will be 50 times what the world will require. 2.2 Principle of working of photovoltaic cell Electricity can be produced from the solar energy by photovoltaic solar cells. When photons from the sun are absorbed in a semi-conductor, they create free electrons with higher energies than the electrons which provide the bonding in the base crystal. Once these free electrons are created, there must be an electric field to induce these higher energy electrons to flow out of the semi-conductor to do useful work. The electric field in most solar cells is provided by a junction of materials which have different electrical properties. The photovoltaic effect can be easily described easily for p-n junction in semi-conductor materials of solar cells which are silicon, cadmium, sulphide/copper sulphide , gallium arsenite. Fig-1 Working principle of photovoltaic cell 2.3 Various type of solar cell Thecomparison of various types of pv-cell is Price Efficiency 1 W size Current production Single crystal High 10-17% 1 About 30% Polcrystalline Medium 10-13% 1.3 About 60% Amorphous Low 7-10% 1.7 About 10% 2.4 Wind energy Wind energy is an indirect source of solar energy. Factors responsible for wind are- 1. Heating and cooling of the atmosphere which generates convection currents. Heating is caused by the absorption of solar energy on the earths surface and in the atmosphere. 2. The rotation of earth with respect to atmosphere, and its motion around the sun. 2.5 Wind power Three factors determine the output from wind energy converter- 1. The wind speed 2. The cross section of wind swept by rotor, and 3. The overall conversion efficiency of rotor, transmission system and generator or pump. No device, however well designed, can extract all of the winds energy because the wind would have to be brought to a halt and this would prevent the passage of more air through the rotor. The most that is possible is for the rotor to decelerate the whole horizontal column of intercepted air to about one-third of its free velocity. A 100% efficient aerogenerator would therefore only be able to convert upto a maximum of around 60% of the available energy in wind into mechanical energy. Well-designed blades will typically extract 70% of the theoretical maximum, but losses incurred in the gear box, transmission system and generator or pump could decrease overall wind turbine efficiency to 35% or less. The wind mill works on the principle of converting kinetic energy of wind to mechanical energy. The mass of wind is- à ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦.. (1) Kinetic energy of wind is- Watts à ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦ (2) But, the power is nothing but kinetic energy of wind. Hence, available wind power- Watts Watts à ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦.. (3) Where, A= area swept by the blades, m2 V= velocity of wind, m/s à ªÃ à ¬= air density (1.225 kg/m3 at sea level) 2.5 Types of VAWT 1. Savonius rotor Characteristics of Savonius rotor Self-starting Low speed Low efficiency. Advantages: The machine performs at low wind velocity ranges. It has simple construction, hence easy to manufacture. Cost of VAWT may be significantly lower than that of standard wind turbine. Ground level mounting. Overall weight of the turbine may be substantially less than of conventional system. Disadvantages: This type of machine is too solid, having so much metal It is not useful for a very tall installation because a long drive shaft problems. 2. Darrieus rotor Characteristics of Darrieus rotor Not self-starting High speed High efficiency Potentially low capital cost Advantages: Rotor blades can accept the wind from any direction Ground level mounting Eliminate yaw control mechanism Less airfoil fabrication cost Disadvantages: It requires external mechanical source for start up At low height, it experiences a lower wind velocity compare to conventional turbines 3. MAGNETIC LEVITATION 3.1 Principle As we know that, when two like poles of magnet are bring together, they get repels from each other. This characteristic of magnet is used for the suspension purpose in vertical axis wind turbine. Due to the absence of physical contact between magnetic bearings, there is benefit of no friction and hence no wear. Also the no need of lubrication, no power loss and the absence of noise generation. Fig-2 Principle of Magnetic Levitation 3.2 Magnet Selection The strength of magnet to get attract or repels is depend on its material configuration. There are basically four categories of magnet that are alnico, ceramic, samarium cobalt and neodymium iron boron (Nd-Fe-B). Nd-Fe-B is the newest invention out of these which exhibits strongest magnetic properties. This magnet is used for the suspension purpose in VAWT. The repelling force exerted by these magnets holds the weight as well as force exerted by wind turbine. Fig-3 B-H curve of different magnets [1] From figure B-H curve depicts attractive magnetic characteristics of Nd-Fe-B offering high flux density with the ability of resisting the property of demagnetization. The permanent magnets selected were N-42 grade Nd-fe-B having ring shape which consist of nickel plating for strengthening and protecting the magnet. 3.3 Magnet placement To obtain thenecessary suspension for wind turbine, two ring shaped Nd-Fe-B magnets are arranged at the middle of the shaft. Magnetic suspension leads to frictionless, noiseless, maintenance less and power loss less rotations of rotor over stator. The similar 8 number of Nd-Fe-B disc shaped magnets are located around the bottom side periphery of wooden disc at above the top magnet. The flux generated by these disc shaped magnets is used for power generation with the help of the generator. Fig-4 Placement of ring magnet on turbine shaft Fig-5 Placement of disc magnets on rotor 4. COIL DESIGN AND ITS ARRANGEMENT To design the definite number of turns per coil is difficult. If the more turns are wound it increase the emf generated from each coil but increase the size of the every coil. For minimizing the size, wire having higher gauge can be used. If the diameter of wire is small low amount of current will flow leading to heating ofwire because of the increased resistance of wire which is another difficult task. Field density is the problem attached with large size coil for designing the generator for given application. Increase in gap between two magnets by increasing height of coil results in reduction of magnetic flux. Hence necessary voltage and current must be balanced. Fig-7 Coil arrangement on stator 5 HYBRID SYSTEM Sometimes due to unavailability of any single resource that is either solar energy or wind energy, there is effect on efficiency of such system. Also to decrease the load on single system, we can interconnect the solar system and wind system together. The output of solar system is DC and that of wind system is AC. So by the use of rectifier AC can be converted to DC and finally this combined DC is given to battery for storage purpose. Fig-8 Hybrid system 6. ENERGY STORAGE When there is no need of generated electrical energy or when the generated energy is excess than demand for application, there is need to store electrical energy. Therefore a 12V battery is used for storage purpose. The electrical energy is stored in the battery in the form of chemical energy when not to used and get convert from chemical energy to electrical energy When required to be used. 7. CONCLUSION The efficiency and effectiveness of VAWT increases due to the use of magnetic levitation principle. For domestic application it is convenient to use Maglev turbine than to use conventional turbine as it requires less space and also low initial and maintenance cost. Maglev turbine with large capacity gives more power than conventional horizontal axis turbine. To decrease the load on any single system, the concept of interconnection of solar and wind is very helpful. This hybrid system along with streetlight application can be used for several domestic applications like mobile and laptop charging, CCTV, to enlighten the single room etc. Use of renewable energy sources with initial investment can make the user free from electricity bill. 8.

International Eugenics Essay -- Genetics
Throughout the history of international relations, the study of human diversity has held a key role in establishing the political principles and recognized shared culture that defines nationhood. Nations have traditionally been associated with a specific geographic location and political ideology, but they also have ethnical identifiers associated with this shared culture. These ethnical identifiers were thrust onto the world stage during the end of the nineteenth century with the introduction of the study of eugenics. The purpose of this study is to examine the historiography of the eugenics movement as it occurred globally, providing a comparative survey of programs, legislation and ideologies in multiple nation settings. In order to provide a global comparative study of international eugenic programs and ideologies, several disciplines will be followed, focusing on four major terms used to delineate eugenics, ââ¬Å"population, quality, territory, and nation.â⬠Although eugenics has been seriously examined by historians since the 1960ââ¬â¢s, international comparisons are a recent addition to the field of research, emerging near the end of the twentieth century. Even as these comparative studies become more popular, the majority of this research focuses on eugenics in Britain, Germany, and the United States. For these reasons, this study will attempt to highlight the movement outside of the Western world only drawing on their historiography as precedence throughout the global community. In 1963, Mark H. Haller published Eugenics: Hereditarian Attitudes in American Thought. As the first major history of American eugenics, Haller encapsulated the movement and only hinted at the biological doctrines of the Naziââ¬â¢s and Soviet Union. Haller... ..., G. R.

In languages, there are set of rules about the use of words in the creation of messages. The usage of language in interpersonalcommunication can be either spoken or written. Below are some features of a language or connected with language: a) Phonology ââ¬â sounds of language ) phoneme ââ¬â smallest unit of sound, example; cat, tdk ââ¬â why is cat correct but not tdk, English has 45 phonemes (ch, th) c) Morphology -smallest units of meaning, example, morpheme, happy, happiness, unhappiness d) Semantics -study of meaning of words, the understanding of vocabulary in order to function in a language. There are two types of meanings in languages: i) denotative meanings ââ¬â public, objective, legal meanings of words ii) connotative meanings ââ¬â personal, emotionally charged meanings For example, What does test me an to you? e) Syntactics -relationships of words to one another, word order f) Pragmatics ââ¬â effect of language on human perceptions and behaviors ) Translation ââ¬â transfer of written verbal codes between language, has time h) Interpretation ââ¬â oral process of moving from one code to another Examples of Language Language follows culturally determined patterns which influence thinking. Some examples: ââ¬â English is linear, Arabic combines ideas through conjunctions, hard to discover main idea when translating into English. ââ¬â England, Ireland, Canada, USA ââ¬â all speak English, is it the same? ââ¬â Arabic ââ¬Å"inshallahâ⬠, intonation, Arabic uses exaggeration, overassertion, repetition, elaboration, 10 words for English, 100 words for Arabic. ââ¬â Writers Shakespeare used 34,000 words, today a good writer 15,000-20,000. Eskimos have 30 words for snow. 9 B) Non Verbal InterpersonalCommunication Non-verbal InterpersonalCommunication uses non-verbal codes as means of communication between cultures. Non-verbal codes are as the following: â⬠¢ is a multichanneled process â⬠¢ spontaneously performed â⬠¢ possess nonlinguistic behaviors â⬠¢ enacted subconsciously â⬠¢ can be intentional or unintentional â⬠¢ is not taught, but learned through observation and experiences Characteristics of Nonverbal Codes Non-verbal codes function as a silent language and impart meanings in subtle and covert ways, continuous, natural, blur into another, less precise. Relationship of Verbal to Nonverbal: 1. accent the verbal 2. omplement the verbal (smiling, pointing) 3. contradict the verbal (nonverbals are opposite to spoken) 4. regulate the conversation (looking, gestures) 5. substitute, take the place of the verbal Cultural Universals in Nonverbal Communication 1. same body parts are used 2. convey similar meanings 3. accompany verbal 4. motives are the same 5. control and coordinate contexts and relationships that are the same Cultural Variations in Nonverbal Communication 1. repertoire of behaviors are different 2. display rules ââ¬â when and where 3. interpretations of meanings. 4. random 5. idiosyncratic 6. shared meaning and significance Body Movements ââ¬â Kinesics Refers to gestures, head movements, facial expressions, eyes. 1. Emblems ââ¬â nonverbals that have direct verbal counterpart 2. Illustrators ââ¬â accompany the verbal, more easily understood 3. Affect ââ¬â show feelings, emotions, body and face 4. Regulators ââ¬â synchronize behavior, control the flow of conversation 5. Adapters ââ¬â reaction to physical state, scratching, unintentional Space ââ¬â Proxemics Refers to how people use physical space. Example: cold means having large physical distances and warm means having smaller physical distances. Touch Affects positive and negative feelings and may denote the following meanings: â⬠¢ playfulness â⬠¢ control â⬠¢ ritual purpose â⬠¢ task related Time ââ¬â Chronemics Here, time is the main determinant of communication and is used in various: Example, past oriented means having a circular approach to life , present oriented means enjoying the spontaneity of the situation and future oriented means tomorrow. Voice Refers to the use of different tones of voices when communicating. Example, Through pitch, rate of talking, rhythm and volume Chemical codes Here, smell is used when communicating, for example wearing perfumes 10 Conclusion 1. Communication is a process when a sender transmits a message to a receiver using a particular medium. The medium used can either be verbal or non-verbal, which includes printed or electronic medias. 2. Culture refers to a group of people or society that has the share the same norm (what is expected of an individual) and values (what is considered good or bad in that particular group or society). 3. A group or society that live in close proximity with one another is called a community. 4. Cultures can be distinguished based on certain dimensions like Low Context Culture, High Context Culture, Individualism, Collectivism, High Power Distance, Low Power Distance, Low Uncertainty Avoidance, High Uncertainty Avoidance, Masculine, Feminine, Monochronic, Polychronic, Acquired Status and Given Status. 5. For the people in a group or society to interact with one another, communication is necessary.

Discipline Among Children and Solutions for our Society essays
Discipline Among Children and Solutions for our Society essays Almost everyday in the news, we hear about a problem with undisciplined children. Sometimes there is a report of a school shooting or a child who went on a rampage against his entire family. It is absurd that the United States, one of the most powerful countries in the world, cannot control a situation like this. Children are our future. Parents should be in charge of most of the discipline in their lives. Schools are for education, not just discipline. When children are not punished, they think they can get away with anything. One of the few legal punishments is grounding. This makes children more rebellious. Corporal punishment is a very controversial issue in our society today. In our society today we have people for and against corporal punishment. Usually the conservatives are for corporal punishment because they believe that the older generations that were subject to it did not have the same problems as today. While the liberals that are against corporal punishment believe that issues with violence in our children have not been proven to be a direct result of corporal punishment. The presence or absence of corporal punishment really producing the results we desire for our society? America is not giving children the discipline or education that they need. Although there may not be many immediate solutions to the growing number of problems with discipline in children, there is enough that we can do now to minimize future problems in our society of growing kids. If Americans work together to develop firm guidelines for disciplining our children then we may be able to decrease the magnitude of disciplinary problems in our future. Mostly parents are to blame for the way a child will act. The old solutions such as teaching your child respect for the law, communicating with your child and spending more time together as a family have failed to be successful in the discipline of children because those solutions nee...

buy custom Law of Purchasing and Supply essay
buy custom Law of Purchasing and Supply essay Question 1 Subject to sale of goods Act, there is no disguised condition as to the quality of any particular purpose of goods supplied. The rule of Caveat Emptor which in simple terms means buyers beware is greatly applied in sale of goods contracts. However, when the sale in question is made by description, the rule is departed in favor of the rule for goods sold by description. The latter rule states that goods sold by description should meet the description thereof or else, the buyer has the right to repudiate the contract. In this case, the car sold did not correspond to the description and the plaintiff (buyer) could therefore maintain an action against the defendant (seller). Case Law Grant v Australian knitting Mills Ltd (1936). The plaintiff went to the defendants shop and asked for a pair of long wooden underwear. The goods were displayed on the counter before him and a sales assistant selected a pair which he bought. The underwear contained an excess of sulphite and the plaintiff contracted dermatitis after wearing it. Held: the chemical should have been removed before the underwear was sold. The defendant was therefore liable. Sues Luxury Cars (SLC) will be held liable for the negligent advice that Tina gave to Richard as implied in the warranty of disclosing the dangerous nature of the goods to the ignorant buyer. Tina breached s13. As in the case, Oscar Chess v Williams, the descriptive statement which is part of s13 is incorporated into the contract. In case they knew that the car was not defective, and its sign was not the actual one and that Richard is ignorant of the condition of the car thus; they are held liable for not warning Richard of the probable danger. Question 2 One of the essentials of a valid contract is the existence of offer and acceptance. In this case, MHL offered cottage. This was a conditional offer as some conditions had to be fulfilled for the contract to become binding. Paul and Richard indeed complied with the conditions and the contract therefore became binding. It is imperative to know that though an offer made through post becomes effective when the letter is received by the offeree, acceptance by post becomes effective from the time the acceptance letter is posted and not when the letter is actually received by the offeror. In the case at hand therefore, Paul and Richard, having posted the acceptance letter before the offer could lapse, had bound MHL. They can therefore maintain a legal action against MHL for letting the room in question. The fact that MHL had not received the letter of acceptance and the money is no defense in law. Case Law The case in Byrnev. Van Tien Hoven: it was held that the acceptance was effective when the plaintiffs posted their letter on October 11th in New York although the defendants in Cardiff were not aware of the posting. Upon suing for damage, Paul and Richard are entitled to recover a reasonable amount for the expenses incurred. They are also entitled to the down payment they had made. Question 3 Petrolheads would be held liable for the damages caused to Sue. In this scenario, the rule of vicarious liability is applicable. The rule states that an employer is liable for the torts committed by his servant provided they are working in the course of their employmment. The employee who caused injury to Sue was acting in the course of his employment and this makes his employer liable thereof. Case Laws In Lloyd v Grace Smith CO 1912 A.C. 716, the plaintiff had sought advice from the defendants, a firm of solicitors whose managing clerk conducted conveyancing work without supervision. He advised the plaintiff to sell some property fraudulently persuading her to sign certain document that transferred the property to him. He disposed of it and kept the proceeds. Held: even though the fraud had not been committed for the benefit of the employers, nevertheless, they were liable for the clerk had been placed in a position to carry over such work and had acted throughout in the course of his employment. Furthermore, when they put their notice, they dont specify to their customers what may cause harm to them while within their premises so that necessary precautions may be laid down. When Trevor, an employee, knock Sue down, he should be held liable for his negligence. He should do what a reasonable persons needs to do while discharging his duty. Petrolheads cannot exclude or restrict liability for negligence even though Sue was aware of the notice. Being aware of the terms in it should not be taken as indicating his voluntary acceptance of any risk. A person cannot so exclude his liability for negligence except in so far as the notice made satisfies the requirement of reasonableness. In this case, Perolheads cannot protect Trevor for his negligence, hence, he should be held liable for the damages caused. Petrolheads should be held liable for the duty of care for the occupiers of their premises, so Sue is entitled for the damages caused to him by Trevor. Buy custom Law of Purchasing and Supply essay

Health care Essay Example | Topics and Well Written Essays - 500 words - 5
Health care - Essay Example There are volunteers who are assigned to have a substantial commitment for several months, whereby they are expected to serve for at least four to three hours daily every week. Moreover, the volunteers learn about the medical profession, and they become a part of the team, which is dedicated to offering high quality health care services. The clinic has breast cancer survivors and advocates of breast cancer awareness, who are inspired by their memories to treat patients with personalized attention, by the use of diagnosis and treatment approaches (The University of Texas MD Anderson Cancer Center, 2012). The Womenââ¬â¢s clinic receives government funding to support their health care programs such as campaigns for creating awareness of breast cancer. The federal funding supports the clinic in acquiring the required equipment in order to offer quality health care services. The clinic faces the challenge of obtaining substantial funds in order to cover for expenses incurred in the process of delivering heath care services. Moreover, the acquisition of financial resources from various sources may take a long process that may derail the effort of offering quality health care services. The clinic is faced by a challenge of managing diversity in the organization, since there are different professional in the organizations, who have different cultures and ethnic background. Therefore, there is a problem of the language barrier, which has a negative impact on communication (Bickell, Shastri & Fei, 2008). By being a charity-based clinic, it has to depend on donations from interested individuals and organizations. These donations are not reliable since there is no stipulated moment that the clinic receives the donations, and they cannot predetermine the mount, thus resulting to a problem when budgeting. The emotional chances in the environment related to the effort to

Not all Women experience oppression in a uniform way Research Paper
Not all Women experience oppression in a uniform way - Research Paper Example xperience, there is evidence that colored women have experienced the severest form of discrimination in countries such as Canada, and the White women are treated far much better. The history of gender disparities is historical and has punctuated the history of the world. Men have consistently resisted the struggle of women to take up senior positions within the community, and there is evidence that different societies have resisted differently. From this perspective, it is clear that different women have experienced oppression in different proportion and that men have been behind this ordeal. The idea that women are the enemies of their empowerment is acceptable to some extent but only contributes to a small proportion of the problems that women have encountered. Conventional politicians criticize the politics of sisterhood on different relative grounds. They argue that by encouraging women to identify their lives as shaped by patriarchal oppression, feminism has produced images of women being victims outside the forces which have consequently denied their critical involvement in most decision-making processes. Bacak (164) believes that by assimilating the differences between women into a sisterhood of common, shared experiences, power relations between women are under-theorized. Both limited and distorted analyzes of gender are in play. Convincingly, it is notable that contemporary feminists criticize the second wave of politics that promote women as victims (Crenwshaw, 2). The critique, in this case, frustrates the perceived inability of second wave feminists to explore and celebrate womens agency instead of presenting women entirely as victims of masculine prejudice. The critique stresses that women shared status as victimsââ¬â¢ acts as a key rhetorical role in generating believes of unity and sisterhood. Nonetheless, Kirkland (89) notes a second wave of feminist driven ideology encourages a gender power relation predominantly altering the difference between men
