Central Solar Heating
Central solar heating is the provision of central heating and hot water from solar energy by a system in which the water is heated centrally by arrays of solar thermal collectors (central solar heating plants - CSHPs) and distributed through district heating pipe networks (or 'block heating' systems in the case of smaller installations). For block systems, the solar collectors are typically mounted on the building roof tops. For district heating systems the collectors may instead be installed on the ground. Central solar heating can involve large-scale thermal storage, scaling from diurnal storage to seasonal thermal energy storage (STES). Thermal storage increase the solar fraction - the ratio between solar energy gain to the total energy demand in the system - for solar thermal systems. Ideally, the aim for applying seasonal storage is to store solar energy collected in the summer time to the winter month. Compared to small solar heating systems (solar combisystems), central s ...

Central Heating
A central heating system provides warmth to a number of spaces within a building from one main source of heat. It is a component of heating, ventilation, and air conditioning (short: HVAC) systems, which can both cool and warm interior spaces. A central heating system has a furnace that converts fuel or electricity to heat. The heat is circulated through the building either by fans forcing heated air through ducts, circulation of low-pressure steam to radiators in each heated room, or pumps that circulate hot water through room radiators. Primary energy sources may be fuels like coal or wood, oil, kerosene, natural gas, or electricity. Compared with systems such as fireplaces and wood stoves, a central heating plant offers improved uniformity of temperature control over a building, usually including automatic control of the furnace. Large homes or buildings may be divided into individually controllable zones with their own temperature controls. Automatic fuel (and sometimes ash ...

Organic Rankine Cycle
In thermal engineering, the Organic Rankine Cycle (ORC) is a type of thermodynamic cycle. It is a variation of the Rankine cycle named for its use of an organic, high-molecular-mass fluid whose vaporization temperature is lower than that of water. The fluid allows heat recovery from lower-temperature sources such as biomass combustion, industrial waste heat, geothermal heat, solar ponds etc. The low-temperature heat is converted into useful work, that can itself be converted into electricity. The technology was developed in the late 1950s by Lucien Bronicki and Harry Zvi Tabor.Harry Zvi Tabor Cleveland Cutler, , 2007.

Zhongba County
Drongpa County or Zhongba County (; ) is a county of Shigatse Prefecture in China's Tibet Autonomous Region. Located in the western part of Central Tibet (sometimes referred to as "western Tibet"), it is the birthplace of the Tsangpo River (Brahmaputra). Zhongba is said to mean "place of wild yaks" in Tibetan. The county seat is at Labrang, which is also called the "Drongpa Township". Geography Drongpa County is the largest county in the Shigatse Prefecture by geographical area. It has a population of approximately 18,000 and covers 43,594 square kilometers. It is prone to earthquakes and suffered a large one, 6.8 on the Richter scale, on 30 August 2008. Although the temblor left a north-south crack at the epicenter located at 31° north and 83.6° east, and houses were damaged and roads blocked by falling rocks, there were no reported injuries. The county is dotted with lakes such as Taro Tso, Nganglha Ringtso and Rinchen Shubtso. Drongpa County shares the Tibet Autonom ...

Electrowinning
Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal. Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purification of non-ferrous metals. The resulting metals are said to be ''electrowon''. In electrowinning, an electrical current is passed from an inert anode (oxidation, made out of lead (Pb)) through a ''leach'' solution containing the dissolved metal ions so that the metal is recovered as it is deposited in an electroplating process onto the cathode (reduction, stainless steel, aluminium (Al), titanium (Ti)). In electrorefining, the anode consists of the impure metal (e.g., copper) to be refined. The impure metallic anode is oxidized and the metal dissolves into solution. The metal ions migrate through the acidic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CODELCO
Codelco (''Corporación Nacional'' ''del'' ''Cobre de Chile'' or, in English, the National Copper Corporation of Chile) is a Chilean state-owned copper mining company. It was formed in 1976 from foreign-owned copper companies that were nationalised in 1971. The headquarters are in Santiago and the seven-man board of directors is appointed by the President of the Republic. It has the Minister of Mining as its president and six other members including the Minister of Finance and one representative each from the Copper Workers Federation and the National Association of Copper Supervisors. It is currently the largest copper producing company in the world and produced 1.66 million tonnes of copper in 2007, 11% of the world total. It owns the world's largest known copper reserves and resources. At the end of 2007 it had a total of reserves and resources of 118 million tonnes of copper in its mining plan, sufficient for more than 70 years of operation at current production rates. ...

Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile. In 1818, after declaring in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atacama Desert
The Atacama Desert ( es, Desierto de Atacama) is a desert plateau in South America covering a 1,600 km (990 mi) strip of land on the Pacific coast, west of the Andes Mountains. The Atacama Desert is the driest nonpolar desert in the world, and the second driest overall, just behind some very specific spots within the McMurdo Dry Valleys as well as the only hot true desert to receive less precipitation than the polar deserts, and the largest fog desert in the world. Both regions have been used as experimentation sites on Earth for Mars expedition simulations. The Atacama Desert occupies , or if the barren lower slopes of the Andes are included. Most of the desert is composed of stony terrain, salt lakes (''salares''), sand, and felsic lava that flows towards the Andes. The desert owes its extreme aridity to a constant temperature inversion due to the cool north-flowing Humboldt ocean current and to the presence of the strong Pacific anticyclone. The most arid re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sundrop Farms
Sundrop Farms is a developer, owner and operator of high tech greenhouse facilities which grow crops using methods which reduce reliance on finite natural resources when compared to conventional greenhouse production. Sundrop Farms opened its first pilot facility in Port Augusta, South Australia, in 2010 (operating as Seawater Greenhouse Australia Pty Ltd). This facility was originally designed as a Seawater Greenhouse. However, significant technology changes led to the Sundrop System, and the dissolution of the joint venture with Seawater Greenhouse Ltd. Sundrop Farms commissioned an expanded 20 ha facility south of Port Augusta in 2016. Sundrop Farms has offices in London, UK and Adelaide, Australia. In October 2016, Sundrop Farms was operating greenhouses in Portugal, the United States and had another facility planned in Australia. Sundrop system The primary inputs to a greenhouse are heat, electricity, water, and nutrients. The Sundrop System is a collection of technologies w ...
