The Big Dish (solar Thermal)
The Big Dish is a parabolic dish concentrator developed by the Australian National University's Solar Thermal Group. The initial prototype, SG3 , was constructed on the Canberra campus of the Australian National University in 1994. A modified version of SG3 was exported to Ben-Gurion National Solar Energy Center at the Ben Gurion University in Israel. In 2006, a joint project led by the Solar Thermal Group with commercial partner Wizard Power, and funding from Australian's Government's Renewable Energy Development Initiative, began the design and construction of SG4 . SG4 is located next to the SG3 dish, and was completed in 2009. Wizard Power held the patent rights for the SG4 Big Dish structure and was planning on developing commercial installations of hundreds of dishes delivering tens to hundreds of megawatts of power. In 2013, the first of these projects, the Whyalla Solar Oasis, which would use 300 Big Dishes to deliver a 40MWe solar thermal power, was canceled a ...

ANU SG4 Dish October 2014
Anu ( , from ð’€ ''an'' "Sky", "Heaven") or Anum, originally An ( ), was the divine personification of the sky, king of the gods, and ancestor of many of the deities in ancient Mesopotamian religion. He was regarded as a source of both divine and human kingship, and opens the enumerations of deities in many Mesopotamian texts. At the same time, his role was largely passive, and he was not commonly worshipped. It is sometimes proposed that the Eanna temple located in Uruk originally belonged to him, rather than Inanna. While he is well attested as one of its divine inhabitants, there is no evidence that the main deity of the temple ever changed; Inanna was already associated with it in the earliest sources. After it declined, a new theological system developed in the same city under Seleucid rule, resulting in Anu being redefined as an active deity. As a result he was actively worshipped by inhabitants of the city in the final centuries of the history of ancient Mesopotamia. ...

Wizard Power
Wizard Power Pty Ltd was an Australian company headquartered in Canberra, focused on solar technology research, development, and commercialization. One of their notable contributions was the creation of the Big Dish, the world's largest paraboloidal dish solar concentrator. Technology In conjunction with the Australian National University, Wizard Power developed a suite of advanced solar mirror panel technology specifically designed for Big Dish and other solar concentrators. These mirror panels, along with their unique thermal and thermochemical solar energy storage systems, played a crucial role in delivering large-scale, zero-emission thermal and electrical energy for various dispatchable power applications. Wizard Power positioned themselves as providers of research, development, technology support, and systems integration services necessary to facilitate the implementation of projects utilizing their solar technologies. Moreover, the company had ongoing initiatives in de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Thermal Collector
A solar thermal collector collects heat by Absorption (optics), absorbing sunlight. The term "solar collector" commonly refers to a device for solar hot water panel, solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and Solar power tower, solar towers or non-water heating devices such as solar cookers or solar air heaters. Solar thermal collectors are either non-concentrating or concentrating. In non-concentrating collectors, the aperture area (i.e., the area that receives the solar radiation) is roughly the same as the absorber area (i.e., the area absorbing the radiation). A common example of such a system is a metal plate that is painted a dark color to maximize the absorption of sunlight. The energy is then collected by cooling the plate with a working fluid, often water or glycol running in pipes attached to the plate. Concentrating collectors have a much larger aperture than the absorber area. The aperture is ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concentrating Solar Power
Concentrated solar power (CSP, also known as concentrating solar power, concentrated solar thermal) systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight into a receiver. Electricity is generated when the concentrated light is converted to heat (solar thermal energy), which drives a heat engine (usually a steam turbine) connected to an electrical power generator or powers a thermochemical reaction. As of 2021, global installed capacity of concentrated solar power stood at 6.8 GW. As of 2023, the total was 8.1 GW, with the inclusion of three new CSP projects in construction in China and in Dubai in the UAE. The U.S.-based National Renewable Energy Laboratory (NREL), which maintains a global database of CSP plants, counts 6.6 GW of operational capacity and another 1.5 GW under construction. Comparison between CSP and other electricity sources As a thermal energy generating power station, CSP has more in common with thermal power st ...

Solar Tracker
A solar tracker is a device that orients a payload toward the Sun. Payloads are usually solar panels, parabolic troughs, Compact linear Fresnel reflector, Fresnel reflectors, lens (optics), lenses, or the mirrors of a heliostat. For flat-panel photovoltaic systems, trackers are used to minimize the angle of incidence (optics), angle of incidence between the incoming sunlight and a photovoltaic panel, sometimes known as the cosine error. Reducing this angle increases the amount of energy produced from a fixed amount of installed power-generating capacity. In standard photovoltaic applications, it was predicted in 2008–2009 that trackers could be used in at least 85% of commercial installations greater than one megawatt from 2009 to 2012. As the pricing, reliability, and performance of single-axis trackers have improved, the systems have been installed in an increasing percentage of utility-scale projects. According to data from WoodMackenzie/GTM Research, global solar tracke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Thermal Energy
Solar thermal energy (STE) is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in Industrial sector, industry, and in the residential and commercial sectors. Solar thermal collectors are classified by the United States Energy Information Administration as low-, medium-, or high-temperature collectors. Low-temperature collectors are generally unglazed and used to heat swimming pools or to heat ventilation air. Medium-temperature collectors are also usually flat plates but are used for heating water or air for residential and commercial use. High-temperature collectors concentrate sunlight using mirrors or Lens (optics), lenses and are generally used for fulfilling heat requirements up to () / 20 Bar (unit), bar (300 psi) pressure in industries, and for electric power production. Two categories include Concentrated Solar Thermal (CST) for fulfilling heat requirements in industries, and concentrated solar power (CSP) when th ...

Energy Conversion
Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. In physics, energy is a quantity that provides the capacity to perform Work (physics), work (e.g. lifting an object) or provides heat. In addition to being converted, according to the law of conservation of energy, energy is transferable to a different location or object or living being, but it cannot be created or destroyed. Limitations in the conversion of thermal energy Conversions to thermal energy from other forms of energy may occur with 100% efficiency. Conversion among non-thermal forms of energy may occur with fairly high efficiency, though there is always some energy dissipated thermally due to friction and similar processes. Sometimes the efficiency is close to 100%, such as when potential energy is converted to kinetic energy as an object falls in a vacuum. This also applies to the opposite case; for example, an object in an Elliptic orbit, elliptical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
