An urban precedent explaining why your choice of city illustrates Essay

An urban precedent explaining why your choice of city illustrates appropriate qualities necessary in a sustainable city - Essay Example The central theme of the Cliff City project is ‘green’ architecture, meaning that it firmly lays emphasis on sustainability and preservation of surrounding ecology. Apart from the usual urban provisions for a library, pub and cafà ©, the project features such innovations as roof-top gardens and has equipment installed for tapping wind and solar energy. Examples such as these not only point the future direction of urban architecture, but also expose the deficiencies of conventional methods of design and construction that was insensitive to the demands of the environment. For example, urban planners throughout the twentieth century paid very little attention to how their constructions will interact with the enveloping environment. The design of Cliff City project near Portland, Dorset breaks away from this tradition, in that it sees architecture as an organic enterprise. It is also informed by the drawbacks of traditional styles of architecture, as it attempt to incorpora te remedial measures toward preservation of organic world. In this respect, the Cliff City stands as a near-perfect model for the perusal of urban planners. Planet Earth is already being damaged by industrial effluents, over-exploitation of water resources, alarming levels of toxic pollutants like carbon monoxide and the phenomenon of Global Warming. In the backdrop of humanity’s appalling record at preserving the natural environment, projects such as the Cliff City, serve as ideal examples of how urban architecture should to be approached in the future. Cliff City’s more relevant today than at any time in the past, as planet earth is confronted with problems of over-population, increased urbanization, genetically modified seeds in agriculture, rising sea levels, etc. A good starting point for mitigating this precarious situation would be the adoption

Organic electronic - Essay Example Traditional electronics, involving the use of inorganic conductors, including copper and silicon, presents a use of materials that are heavier and more expensive than conductive polymers and organic semiconductors include dielectrics, conductors and light emitters that have many and varied applications in the field of electronics (Sun, 2008, Chapter 5) and (Wikipedia, 2010, â€Å"Organic Electronics†). Already, organic electronics based displays using organic light emitting diodes have found their way into car radios, etc., with rapid improvements expected in organic field effect transistors. According to published reports, the market for organic materials will be worth US$ 4.9 billion on 2012, and this will surge to US$15.8 billion in the year 2015 (Allen, 2008, Pp. 6). The previously mentioned author states that new kinds of semiconductor materials, including rubrene, hybrid materials and formulations made of carbon nanotubes will continue to spur the market to grow to US$4.9 billion by the year 2015, with the organic electronic substrate business growing to US$ 6.9 billion. According to NanoMarkets (2007, "Organic Harvest: Opportunities in Organic Electronic Materials"), eighty percent of organic electronic materials will be sold into the RFID, display backplanes and Organic Light Emitting Diode (OLED) lighting and displays applications. However, according to the previously mentioned report, if organic electronics is to continue on the road to success, it will have to emulate the traditional semiconductor industry and invent an organic version of CMOS with its own sta ble material sets. Thus, firms specialising in materials for electronics and organic electronic materials must offer commercial quantities of n-type semiconductors and organic dielectrics. In addition, the previously mentioned report suggests that for
