Santa Cruz Province, Argentina
Santa Cruz Province ( es, Provincia de Santa Cruz, , 'Holy Cross') is a province of Argentina, located in the southern part of the country, in Patagonia. It borders Chubut Province to the north, and Chile to the west and south, with an Atlantic coast on its east. Santa Cruz is the second-largest province of the country (after Buenos Aires Province), and the least densely populated in mainland Argentina. The indigenous people of the province are the Tehuelches, who despite European exploration from the 16th century onwards, retained independence until the late 19th century. Soon after the Conquest of the Desert in the 1870s, the area was organised as the Territory of Santa Cruz, named after its original capital in Puerto Santa Cruz. The capital moved to Rio Gallegos in 1888 and has remained there ever since. Immigrants from various European countries came to the territory in the late 19th and early 20th century during a gold rush. Santa Cruz became a province of Argentina in 1957. ...

Santa Cruz River (Argentina)
Santa Cruz River ( es, Río Santa Cruz) is a river in the Argentine province of Santa Cruz. The Santa Cruz begins at the shore of the Viedma and Argentino Lakes, of glacial origin and located in the Los Glaciares National Park, and runs eastwards before reaching the Atlantic Coast, north of the southern tip of South America, creating a delta. It is one of the last large free-flowing rivers in Patagonia. Dams The river has an important flow of on average, and is used for irrigation. Two dams are planned for the river, the Jorge Cepernic and Nestor Kirchner Dams. They will have a combined installed capacity of 1,740 MW. Contracts to construct the dams were awarded to a consortium of Chinese and domestic companies in August 2013. It is estimated that the dams will destroy over half of the Santa Cruz River ecosystem. History Santa Cruz River was discovered by Europeans during Magellan's circumnavigation of the Earth, by Juan Serrano, captain of the ''Santiago'', one of ...

Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...

Kaplan-type
The Kaplan turbine is a propeller-type water turbine which has adjustable blades. It was developed in 1913 by Austrian professor Viktor Kaplan, who combined automatically adjusted propeller blades with automatically adjusted wicket gates to achieve efficiency over a wide range of flow and water level. The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low-head applications which was not possible with Francis turbines. The head ranges from and the output ranges from 5 to 200 MW. Runner diameters are between . Turbines rotate at a constant rate, which varies from facility to facility. That rate ranges from as low as 54.5 rpm (Albeni Falls Dam) to 450 rpm. Kaplan turbines are now widely used throughout the world in high-flow, low-head power production. Development Viktor Kaplan, living in Brünn, Austria-Hungary (now Brno, Czechia), obtained his first patent for an adjustable blade propeller turbine in 1912. But t ...

Concrete-face Rock-fill Dam
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam.

Jorge Cepernic
Jorge Cepernic (23 February 1915 – 18 July 2010) was an Argentine politician and Governor of Santa Cruz Province between 1973 and 1974. In 1974, during Isabel Perón's term in office, he was removed from office. Afterwards, he was given a five-year jail sentence at the Magdalena jail for allowing the filming of Rebellion in Patagonia during his tenure in office. He was then forced into house arrest with his family in their farm nearby El Calafate. One day he escaped and managed to arrive to a police station, where he waited for the chief of police and asked him to have him removed from his house arrest and sent to a prison so that his family would not be victims of his sentence. On 18 July 2010, Jorge died in his house in Río Gallegos after a long illness at the age of 95. The Santa Cruz governor Daniel Peralta Daniel Román Peralta (born 1 July 1955) is an Argentine Justicialist Party politician who was governor of Santa Cruz Province from 2007 to 2015. Early ...

Hydroelectric
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Buildings And Structures In Santa Cruz Province, Argentina
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
