Queensland, Australia Brisbane, the capital city of the central business district has recently built the world’s largest solar powered sky bridge, October 4 and was open to the public.
Bridge called Kurilpa bridge, it is estimated that about 36500 people a week walking or cycling from the bridge over. Kurilpa bridge across the Brisbane River, connecting the central business district and the Brisbane City South Bank area of art.
Kurilpa the bridge looks like a knitting needle, it is not only the world’s longest pedestrian bridge, one of the bridge but also the installation of an advanced light-emitting diode (LED) lighting systems.
The energy from the sun to provide lighting systems can produce a wide variety of lighting effects. LED lighting systems will be used for a variety of festivals and the lighting along the river Lot. The bridge has 84 solar battery provides power for the LED light arrays, which portabale solar charger-Nissan 100 kwh electricity (100 kWh), the average annual output of power 38 megawatt-hours (38000 kWh). These energies entirely provide the energy needs of the flyover and most lighting needs.
Light-emitting diode (LED) lighting systems than other lighting efficiency is much higher. LED lighting systems will be used for a variety of festivals and the river lot lighting, for example, for the annual Brisbane River Festival, held in Riverfire. The bridge has 84 solar battery provides power for the LED light arrays, which solar batteries, Nissan 100 kwh electricity (100 kWh), the average annual output of power 38 megawatt-hours (38000 kWh).
It is learned that, Kurilpa bridge cost about 63 million U.S. dollars. It is alleged that the longest bridge of its kind, the span of 470 meters wide and 6.5 meters, the bridge thickness of 25 cm. Kurilpa bridge is estimated that 37.8 tons per year will reduce carbon dioxide emissions.
Background About Solar Energy
Solar energy is the sun’s interior or the surface of sunspots continuous fusion reaction produces energy. Earth’s orbit, the average solar radiation intensity 1367w / ?. Circumference of the Earth’s equator as 40000km, in order to calculate the earth to obtain the energy up to 173000TW. At sea level on the standard peak intensity 1kw/m2, a point on the earth’s surface 24h of the annual average radiation intensity of 0.20kw / m², equivalent to a 102000TW energy, human beings rely on these energy to survive, including all other forms that can be renewable energy (except for geothermal resources), although the total amount of solar energy resources is equivalent to the energy used by humans are now ten thousand times, but the solar energy density is low, and it varies from place to place, because from time to time change, which is development and utilization of Solar facing a major problem. These characteristics make it solar charger in the whole role of integrated energy systems are subject to certain restrictions.
Although the solar radiation energy to the Earth’s atmosphere, only its 22 billionth of the total radiation energy, it has up to 173,000 TW, that is exposure to the sun to Earth per second of energy is equivalent to five million tons of coal. Earth wind energy, hydropower, ocean thermal energy, wave energy and biomass, as well as part of the tidal energy comes from the sun; even the Earth’s fossil fuels (such as coal, oil, natural gas, etc.) that is also fundamentally storage of solar energy down from time immemorial, it covered a broad range of solar energy is very large, narrow solar mobile charger is limited to solar radiation of light and heat, photoelectric and photochemical direct conversion.
Solar energy and portble solar charger is primary energy, but also renewable energy. It is rich in resources, both free of charge, but also without transportation, without any pollution to the environment. For mankind to create a new lifestyle, so that social and human energy conservation to reduce pollution entering an era.
