Solar Panel’s Unlimited Energy Boost for Bridge Electricity Needs

Abstract

Various electricity sources to provide electricity needs in Golden Gate Bridge being analyzed to gain the impact of each source to the global warming. In purposed to obtain environmentally-friendly energy source, problem in criteria of pollution resulted, sustainability, impact to the human health, and impact to the environmental still happened in two of three energy sources. Hazardous wastes are produced by the Nuclear reactor which is harmful to the human health, air pollution also occurs in the process of producing energy in Nature gas and highly responsible to the climate change. Either Nuclear reactor or Nature gas cannot provide sustainable energy source because the fuel is formed from non-renewable materials. Both of them revealed the possibilities of disadvantages are more dominant than the expected benefits. The last energy source observed (solar panel) shows different results which are sufficient to the criteria. Moreover, it can be placed in almost every part of the bridge as long as provide sun light, which means not necessary to change the design of the bridge.  This observation suggested using Solar panel as electricity boost to Golden gate bridge electricity needs.

Asphalt

Asphalt is the heaviest fraction of petroleum, left behind when the more volatile compounds evaporate. It flows slowly during warm weather and may be stiff enough to shatter during cold times. Geologists use the word “asphalt” to refer to what most people call tar, so technically this specimen is asphaltic sand. Its underside is pitch-black, but it weathers to a medium gray. It has a mild petroleum odor and can be crumbled in the hand with some effort. A harder rock with this composition is called bituminous sandstone or, more informally, tar sand.

Asphalt is a brownish-black semisolid or solid mixture of bitumen, either from a native source or as a petroleum by-product. Sometimes the term asphalt refers to a mixture of asphalt with sand, gravel or crushed stone.

Asphalt is a natural or artificial mixture in which bitumen is associated with inert mineral matter. It is black or brownish black in color. At temperature between 50–100°C it is in liquid state whereas at temperature less than this it remains in solid state. Because it is a thermoplastic material it softens as it is heated and hardens as it is cooled. It is the basic paving material in use today.Image

Sanghai World Financial Center

The Shanghai World Financial Center (SWFC; Chinese: 上海环球金融中心) is a skyscraper located in the Pudong district of Shanghai, China. It was designed by Kohn Pedersen Fox and developed by the Japanese Mori Building Company. It is a mixed-use skyscraper, consisting of offices, hotels, conference rooms, observation decks, and ground-floor shopping malls. Park Hyatt Shanghai is the hotel component, containing 174 rooms and suites. Occupying the 79th to the 93rd floors, it is the second-highest hotel in the world, surpassing the Grand Hyatt Shanghai on the 53rd to 87th floors of the neighboring Jin Mao Tower.
