Making Solar Energy Economical - Essay Example With the realization of this inefficiency, current manufacturers are manufacturing solar cells with an improved efficiency through laying the cells into multi-layers that has the ability to push the efficiency to about 35%. Using nanotechnology, engineering of solar energy generation devices can make structures on sizes that are comparable to molecules and atoms that are measured in nanometers whereby nanocrystals from the elements selenium and lead are utilized (Beard et al. 2506). The technology improves the inadequacy presented by standard cells that produce useless excess heat and less impact while the Lead-Selenium nanocrystals release further electrons rather than heat thus boosting the output, which can also be replicated in Silicon. With the use of nanocrystals technology, the efficiency of the generation of solar energy can use efficiencies of up to 60% and therefore engineering technologies are required to integrate nanocrystal cells in transmitting energy in a circuit (Bea rd et al. 2512). How to Make Solar Energy Economical The use of new materials for solar cells can help in the reduction of fabrication costs that has a positive impact in reducing the costs of solar energy and making its implementation for generation of electricity economical (Lewis 799). The purity of the material is important, as modern solar cell designs require higher purity content in order to make the flow of electric charges be seamless. To achieve this, manufacturers will be required to use thick materials in one dimension to absorb sunlight and thinner materials in another direction to transmit the charges which would require that the solar cells are made of nanorods or tiny...This essay outlines the growing importance of the solar energy among other sources and determines the factors, that will ensure larger electrical generation based on solar energy conversion. Solar power is usually generated by collecting the light spectrums from sunlight and converting them to energy in the form of electricity using solar panels that have cells in them. Solar energy forms an integral part of the supply of energy to human beings and the earth in general. The contribution of the sun to the energy requirements of the earth is substantial despite the fact that it has not been taken up by most people and forms only a fraction of the energy consumption market. In order to make solar energy economically competitive, there is need for those tasked with the manufacture of solar technology devices to improve the efficiency of the cells in commercial solar cells as well as lower their costs of manufacture. The use of new materials for solar cells can help in the reduction of fabrication costs that has a positive impact in reducing the costs of solar energy and making its implementation for generation of electricity economical Despite the fact that technology may help in the production of solar cells that generate cheap and efficient electricity, it would be uneconomical if the solar energy generated is not stored. The need for storage of electricity generated from solar has been necessitated by the fact that not all the days will the earth receive sunlight as this may be blocked by clouds or darkness at night.

Opposites Attract Essay -- Personal Narrative Essays

Opposites Attract    Perhaps we all have the same memory of the first boy-girl party we attended. The floors were waxed, the music loud, the air thick with the smell of cologne. The boys stood on one side of the room and the girls on the other, each affecting a nonchalance belied by the shuffling male loafers and the occasional high birdlike sound of a female giggle.    Eventually, one of the taller, better-looking boys, perhaps dogged by two slightly shorter, squeakier acolytes, would make the big move across the chasm to ask the cutest girl to dance. Eventually, one of the girls would brave the divide to start a conversation on the other side. We would immediately develop a certain opinion of that girl, so that for the rest of our school years together, pajama parties would fairly crackle when she was not there.    None of us would consciously know it then, but what we were seeing, that great empty space in the center of the floor as fearful as a trapdoor, was the great division between the sexes. It was wonderful to think of the time when it would no longer be there, when the school gym would be a great meeting ground in which we would mingle freely, girl and boy, boy and girl, person to person, all alike. And maybe that's going to happen sometime in my lifetime, but I can't say I know when.    I've thought about this for some time, because I've written some loving things about men, and some nasty things too, and I meant them all. And I've always been a feminist, and I've been one of the boys as well, and I've given both sides a pretty good shot. I've spent a lot of time telling myself that men and women are fundamentally alike, mainly in the service of arguing that women... ... we still managed to pick partners and dance. It's the dance that's important not the difference (I shouldn't leave out who leads and who follows. But I speak to that from a strange perspective, since any man who has ever danced with me can attest to the fact that I have never learned to follow.)    I have just met the dance downstairs. My elder son has one of his best friends over, and he does not care that she is a girl and she does not care that he is a boy. But she is complaining that he is chasing her with the plastic spider and making her scream and he is grinning maniacally because that is just exactly the response he is looking for, and they are both having a great time. Two children raised in egalitarian households in the 1980s. Between them the floor already stretches, an ocean to cross before they can dance uneasily in one another's arms.

As it was mentioned that Mossier will use half of the proceeds from the sale to start a new fund to support socially minded entrepreneurship, and Bin will match his investment and continue the company's one-for-one shoe give away policy.

Hence, it is evident that millennial are Toms' target demographic that are becoming social entrepreneurs in a big way too to make their own impact and for those who are with social missions, this development is a good step for ward to show that social entrepreneurship can do good and do well simultaneously. Document It is a pleasure to be here today and be part of such a distinguished panel. What I'd like to do in the time allotted is to share some thoughts on the influence of technology on learning in high schools. But first let me make clear what I'm talking about. The technology that is shaping our future and our children's is not, as many assume, the computer. These machines have been with us for decades and now, with their advanced multimedia capability, they deserve considerable credit for enhancing learning among people of all ages. But I propose that there is an even greater technology on the rise.I am speaking about the new and emerging forms of interactive communications, such as the Internet, that allow us to capitalize on our greatest learning resource -? the minds of people all over the globe. We are just beginning to experience the impact of this connection of people to people, and can only guess how transforming its effects will be in the coming years. I also contend, however, tha t if we make the right choices now, we can substantially change for the better how we and our children learn, and more important, how the young people of today and generations to come are taught to learn.To succeed at that task requires a concerted and coordinated effort -? a partnership if you will -? among our families, schools, youth organizations, and communities say that because I am mindful that technology itself is never the reason things change. Rather, it is how people choose to apply technology and whether they make wise decisions and address real needs that makes the difference in the long. There is a quote learned and here I quote: The real power of interactive communications is people as the ultimate source of knowledge.It is not the computers, the physical mass of wires, the complex of networks or the vast databases of information. Rather, it is people and their knowledge, relationships, insights, and spirit freely passed from one to another that engender the â€Å"ma gic† the Internet is making possible. Today, of this interconnected world that the fundamental question is whether we will share this â€Å"magic† with everyone , or only a privileged few. The answer depends on the decisions we aka and the actions we take from this moment on.We must come to understand that access to the Internet needs to be a reality for all our citizens, that the free and unrestricted flow of information and the ready availability of computers for everyone are not simply matters of â€Å"technology. † They are, in fact, one of the vital keys that will either open or lock the doors of opportunity for our children and ourselves. It is within our power to determine whether this generation is to experience the rewards of silverberry, a higher quality of fife, and a renewed sense of community that derive from an interactive sharing of information and knowledge.If we make that leap, and ensure that every citizen has access to the Internet and the chan ce to learn the skills to apply these new technologies for personal advancement as well as the common good, America will make a successful transition to the millennium. If we fail, We may leave a legacy smaller than Our own inheritance. We can get Involved with the New Technologies. Make it a priority. I imagine that getting access to networked computers and finding opportunities for practice and training on the Internet may not be easy for many of you.Investigate local community centers, nonprofit organizations, even corporations, who sometimes make space and courses available to the public. Or you might consider buying a recycled computer. Ask around. But don't give up. Because once you have experienced what I'm talking about -? instant access to information you can use and people with shared interests you'll begin to understand the power of this communications revolution. My friends experience demonstrate to me that, the Internet is a rueful tool for invigorating real communities , not just for building virtual ones.Charlotte Web's success in using communications technology to enrich the lives of an entire region, including the undeserved, so that everyone can participate more fully in community life, should inspire other cities and regions to embark on similar ventures. As a bright woman once told us, we need to ensure our children a head start in a difficult and forbidding world. Document The concert was phenomenal. I was an amazed by how Dry.

Abstract The theme of cultural transition is well portrayed throughout the two books; Things Fall Apart and The Lion and The Jewel. On the other hand, the elements of change in both books defer, as in Things Fall Apart, what brings the change originates from the outside, that is, the missionaries; while Lakunle acts as the element of change from inside the community. Lakunle understands the customs, and he even grew up practicing them, but after he comes into contact with the outside world, his views are changed. Don’t waste time! Our writers will create an original "Theme of Cultural Transition" essay for you Create order The cultural transition is seen when Lakunle tries to oppose the custom of bride price and calls it uncivilized. He tries to win Sidi’s love using the tactics he has learned from the modernized world but fails terribly. The missionaries in Okonkwo case also seek to change the ways of the people, they introduce formal education and try to bring civilization to Umofia. Their efforts are derailed when Okonkwo opposes them and kills one of their messengers. Conflict is also in both stories; Lakunle fight against the community’s customs is a sign of conflict. Baroka Sidi and the rest of Ilunjule village are traditionists who are uneducated who conflicts with the educated Lakunle a school teacher educated and influenced by the western culture. In the play, The Lion and the Jewel tradition wins against modernity which is evidence by Sidi marrying the traditional chief. The issue of the bride price causes Lakunle to be considered as the village fool. He also fights alone as no one else in the community is willing to share his views; not even his beloved Sidi. Where there is a conflict there is bound to be consequences, in Okonkwo case, his conflict with the missionaries resulted in death and feelings of betrayal. This paper will discuss the various instances where both the jewel and the lion and things fall apart portray the theme of cultural change and theme of conflict. Introduction Change and conflict go hand in hand; especially in a place where what is being changed has been there for a long time. Culture is collectiveness of behaviours acquired by a member of a given group or community. Thus culture is the practices, social behaviour, and beliefs of a given community. In the books we are looking at cultural conflict is shown between the modern and traditional cultures. Cultural transition in both The Lion and The Jewel and Things Fall Apart is eminent as portrayed in the characters of both Lakunle and Okonkwo. Both characters try to bring change to their environment; Okonkwo tries to fight against cultural change while Lakunle is for the change. Cultural African practices were regarded to be sacred, and anything or anyone that interfered with them was considered to be an enemy of the community. The cultural beliefs that the African communities held were believed to hold a certain purpose, and they were what united them with their ancestors. Common belief and practice also symbolized a sense of unity, and it was rare for individuals to separate themselves from this kind of life. For those that managed to separate themselves, they came back and shook these foundations and were regarded with suspicion and even considered to be fools or slaves of the colonists. Conflict is said to be the disagreement between individuals or ideas. In the case of our study conflict can be defined as the clash or disagreement of cultures. Culture is a unique phenomenon cherished and protected dearly by a given community. The two books; the Jewel and Lion and Things Fall Apart show how African cultures are subjected to imposition and displacement by the western culture. Whenever there is change conflict comes long for instance in the case of Lakunle, Lakunle a school teacher feels that he is modernized than any other person in the village. Thus he is not ready to pay the bride price and take Sidi as his wife. Sidi, on the other hand, does not agree with Lakunle she feels that when she accepts to be married by him without the bride price, the village people will be against her. Later on, Sidi is married to the traditional chief and leave Lakunle who is considered a fool by the village people and face opposition from them.   The piece shows that in the instance of change there exist disagreement of given ideas. Body Confronted with complications Lakunle is not convincingly representing the modern ideas as he claims. It is evidence that he misunderstands the modern books he reads and the cultural beliefs. For instance, Lakunle tell Sidi that she has a small brain, meaning women brains are deemed to the smaller and dysfunctional compared to the males brains. His thinking on the women brain capacity is dictated by the traditional belief in his community while he calls himself civilized while in the civilized community everyone is equal be it a man of women. Lakunle is also full of fascinations of the superficial modern way of life, for example, the dances, and ballroom and night clubs, showing that he believes in half-baked ideas that justify his actions of refusing to pay the bride price to Sidi. Baroka the 62-year-old chief oppose development brought about by the white people, he believes that the development destroys the way people live. On the other hand, he feels that he should learn a thing from Lakunle as well as Lakunle learn from him. In the Things Fall Apart we see Okonkwo confronted by complications due to cultural conflicts presented by the white men. After he leaves to exile, the white men were able to thrive and to spread their gospel in the village. When he came back, he meets a different community in which he is unable to live in. Everyone including his son had converted to Christianity. Due to his strong belief in the traditional culture, he chooses to die rather than complying with the white men. The role of women in two texts Women in both Things Fall Apart, and The Lion and The Jewel are considered to be man’s property. They can be purchased and accumulated to man’s wealth. Their only role is to get married and have children. In things Fall Apart Okonkwo acquires many wives who he expects to bear many children to promote his legacy in the community and rival that of his father who he regarded as a failure (Achebe, 13). Baroka on the other hand in the Lion and The Jewel acquires wives to promote his status in the community (Soyinka, 4). He is surprised that in five full months he has not acquired a wife, meaning he considered wives to be an addition to his vast wealth. Lakunle undermines the tradition of purchasing a woman by proposing to Sidi and telling her he will marry her without paying the bride price. In this case, the tradition of paying the bride price is condemned by Lakunle while Baroka embraces it and win Sidi. Women are not supposed to make key decisions in the society, but with modernity, women take roles which there were not supposed to like the harvesting of yams in Thing fall apart. We also see Sidi admiring her picture in the magazine and feels that she deserved better men from outside world since she is being seen by people in the western world. She is held up by the culture and even fails to marry Lakunle a modernized man since he does not want to follow the culture by paying the bride price.   The role of chief in two texts In The Lion and the Jewel, Baroka is the chief, and he represents traditional norms and customs. He stands against any foreign change such as the building of railroad near his village. He agrees with the rail contractors signs a letter that states that the village soil is unfit to support the train engine. He does this so that the rail can be moved away from the village. Being a staunch traditionalist, he understands that the presence of rail in the village will lead to penetration of more white who will change the village people culture to western culture.   He promotes the paying of bride price that is why Sidi prefers him to the modernized Lakunle (Soyinka, 6). In Things Fall Apart, the chief also represents the community customs and also moral authority. He struggles with the new political and religious orders introduced by colonialism which he terms as unmanly and feels that he will betray the community if he complies with the new ways. Okonkwo condemns cultural change since h e fears losing social status. After coming from exile, he is unable to adapt to the colonizer way of life which leads to his suicide. Although his stand is not as rigid as that of Baroka in the face of the British Colonists; he maintains law and order in the community. Contexts colonial versus city/technology/modernity In both texts, any change that is introduced by either colonist or modernity is met with resistance. Okonkwo opposes anything that is related to the British administration. Such that when he returned from exile, he could not tolerate the colonizers way of life and ended up taking his life (Achebe, 58). Baroka resists any form of development pioneered by the colonialists, for example, he rejects the construction of the railway line, saying that the soil along the village is fragile and cannot sustain the weight of the engine. Lakunle, on the other hand, a modernized school teacher tries to modernize his community by changing the rule of the bride price. He faces rejection from Sidi and the entire village for going against the culture that dictates marriage rules in the community. He also wishes for construction of motor roads and railroads. His desires and conversations are met with less enthusiasm than he had expected. Cultural values/impacts/reaction Cultural values are highly upheld in both texts, and that is why any threat towards these values is met with negative reaction. Baroka is a staunch traditionalist that is why he enjoys being a polygamist and does not tolerate the introduction of the modern railroad (Soyinka, 4). He also uses traditional knowledge and practices to win Sidi unlike Lakunle who denounce the cultural practice of paying the bride pride price. Lakunle support modernization he wishes that railroads were built in the village which never happened due to the highly upheld cultural values. Lakunle does not understand why the community promotes backwardness and choose to stay in darkness. He tries to change the cultural values, but he fails terribly. Okonkwo seems like the only one still concerned with the Umuofia’s cultural values. He denies the white men entry into the village and strongly refused their cultural value to be changed especially in the context of religion. He also sent away anyone who compl ied with the white men and considered as an outcast in the community. His reactions, although meant to maintain stability, causes a lot of instability in the community that causes Okonkwo to take his life. Education and religion/tradition The educated people in the two books seek to spread the modern ideas to the uneducated people who believe in their old ways of life. They preach out their knowledge with the aim of changing the tribal people to modern ways. Education is strongly rejected by the traditional people who do not see any good the education can offer to them in sustaining their daily lives. Lakunle is the educated person in the village he is rejected by the people in the village due to his modernized way. The rejection is portrayed by the way he dresses and talks to Sidi. He is also considered a fool by the village people when he refuses to pay the bride price to Sidi and loses her to chief Baroka. Sidi is also not willing to be associated with Lakunle due to his modernized behaviours which do not respect their culture. In the things fall apart the colonization is mostly addressed religiously unlike the Lion and the Jewel. The whites condemn the traditional people religion where they tell them that their gods are evil and cannot help them since they direct them to kill and discriminate innocent people. They introduce their God whom they believe takes care of them and is just and good to all. The traditional people reject their religion and fight against it lead by Igbo. After Okonkwo come from exile, he finds a changed community where everyone has turned to the white man’s way. He finds that some churches have been built together with schools. To his surprise, he finds that even his son has converted to Christianity. His staunch belief in the traditional way of life make him feel out of place, he cannot put up with the new ways and eventually commit suicide. Conclusion The two books prominently discuss the theme of culture clash as a result of rapid modernization brought about by the colonial people. Culture transition is highly advocated by the white people who want to see the last outdated African culture in the featured communities. On the other hand, Africans fights any change advocated by the white people. They feel that they have a rich culture and they should preserve it. Conflict arises when the two culture meet since each side wants to stand by culture and beliefs.
