Dynamics, Fluids & Energy - Assignment Example Source: Prado Miguel, 2009, Renewable Energy sources Energy Energy is needed in all spheres of a life to accelerate growth. The traditional concept of generating energy from fossil fuels that could drive certain machinery is giving way to a more holistic approach where other sources like wind, solar, tidal waves and biomass are also being considered as alternate forms of energy. (Prado Miguel, 2009) Sustainability The reason why man is looking out for other forms of energy is because it has been estimated with the present rate of consumption; fossil fuels will be unavailable in the near future. Hence the idea is to develop or harness an energy source that is always being replenished by nature. This ensures that all the fossil fuel that is available at present is not completely used up and assures that the future generations have also access to this energy source. This forms the basic premise of a sustainable energy. (Prado Miguel, 2009) Renewability Renewability is used to describe t hose energy sources which are abundant in nature and are replenished naturally. The consumption of these energy sources has minimal impact on the environment. Using these energy sources also leads to reducing the carbon dioxide emissions produced by consuming fossil fuels. This has a direct impact on reducing the rate of global warming and forms the most innovative solutions in containing the temperature rise in earth’s environment. (Prado Miguel, 2009) Alternate forms of Sustainable Renewable Energy 1. Solar Energy Since energy from the sun is available abundantly, expertise lies in harnessing this energy effectively. The primary factors involve capturing and converting this solar energy for efficient storage. It is estimated that about 1000 Watts/ square metre fall on the earth’s surface on an average since this is dependent on environmental conditions (National Seminar on Alternative Energy Sources, 2005, p.5) and the climate. A photovoltaic cell (PV) is ideally use d to tap into this light energy and convert it into electrical energy. This is a simple process in which the captured sunlight releases electrons on striking the silicon material. The electrons thus displaced create a hole with a positive charge. (Lewis Nathan and Nocera Daniel, 2006, p. 6801)The released electrons are then made to travel back to these holes via an external circuit thereby generating current. Solar cells can be arranged in series or in parallel to obtain the required voltage and current. Source: National Seminar on Alternative Energy Sources, 2005, VSAT Equipments powered by Solar 2. Wind Energy Wind energy is another form of energy that is available abundantly but requires the right kind of harnessing to be used efficiently. Solar power is indirectly responsible for the generation of wind energy. This is because land surface absorbs solar energy at different rates and hence the air above this land or water mass is heated at different rates. Source: Edelstein, 2003, Windmills in series This unequal heating causes a pressure gradient during which the hot lighter air rises up while the cool denser air flows in to take its place. (Edelstein, et al, 2003, p.2) This gradient thus creates a rapid movement of air which is called wind. A device that could be used to slow down this wind velocity can convert part of the kinetic energy into electrical energy. Wind speed, area of cross section swept by rotor and its efficiency in conversion, Generator properties and the

Advertising for SONY Essay Example | Topics and Well Written Essays - 2500 words

Advertising for SONY - Essay Example Sony Company is an electronic and communications manufacturer. It is based in Tokyo Japan and recorded revenue of eighty eight billion dollars during the year 2008. The company offers a variety of products such as video game merchandises video items for consumption, IT products, electronics and communication devicesThese commodities are produced under the following five categories; entertainment, electronics, games and financial services. Its business operations are Sony Financial Holdings, Sony Ericsson, Sony BMG Music Entertainment, Sony Computer Entertainment and Sony Electronics. (Howard, 2000)One element that makes Sony stand out in the industry is its originality. The company has created standards for their products as depicted in the Betamax system of video recorders. Besides innovation, Sony is a multinational corporation. This gives the company access to a large pool of clients thus complementing sales in one country with those in another. (Collett, 1999)The Sony marketing d epartment seems to be getting on the wrong side of the moral divide as they have been criticised by some media critics. This was brought up by the controversial advertisements that the company has aired. One such example was with regard to a racially charged advertisement. In addition, Sony Company failed to comply with marketing ethics by hiring a marketing critic to praise the performance of their commodities. However, this did not fare well with the real marketing critics. All these bad marketing decisions have tainted the Sony name. Sony's management has been overwhelmed by the technological changes characteristic of the electronic and IT industry. Consequently, the company has had to fire a substantial number of employees who were not familiar with new production technologies and replaced them with a fresh batch. This move has met a lot of criticism from consumers. As matter of fact, some people attribute the company's declining quality in some of its products to this issue. (Collett, 1999) Opportunities The company needs to invest in its employees. High employee turnover is hurting the company's corporate social responsibility image. On top of that, the company is compromising on the quality of the products by frequently firing their employees. The new employees who join the company may not be familiar with some of the production process. In order to curb this problem, the Sony should train its employee regularly in order to prevent these problems. Threats Sony' major threat is being out-competed by its counterpart due to a failure to adapt to technology adequately. This was seen when Sony used Immersion Company's technology to create their play station 3 video game units. The company was forced to pay royalties to Immersion for doing this. Such kinds of approaches to technologies will harm the company in the future; instead, the company should focus on developing their own formats. (Collett, 1999) Review of advertising brand and competitors The adverting brand under consideration is the new online game division for Sony. Sony has a strong brand name that has placed it above other competitors such as JVC. The company dedicated a lot of time trying to come up with the most appropriate name for their products. There are many reasons why this name made a mark for the company. First of all, it is easy to pronounce; many Japan-based companies may settle for difficult names that make it difficult for international consumers to relate to. Additionally, the brand name is easy to remember as very few companies out there have such a name. On top of that, it has the ability to attract people who may not be as well versed with technology as others. Many electronic manufacturers use acronyms instead of full names from their brands thus repelling non-technical consumers. (Howard, 2000
