Ottenbach Small Hydro
The Ottenbach Small Hydro is a 1920 electrified small hydroelectric power station of the former Silk Weaving Mill A. F. Haas & Co. in the Swiss village of Ottenbach. It is preserved in its original condition of 1920, still able to operate, aimed to be an historical witness of the industrial archaeology. The ensemble of factory, power plant and hydraulic structures is a cultural asset under preservation order. History From 1645 onwards, the millers of Ottenbach and Rickenbach used in addition to the ditches in the village the water of the river Reuss to grind the grain, because those did not supply enough water during the summer months. In 1833, the Canton of Zürich granted the license to use the water to operate a grain mill. In 1836 the miller Jakob Beerli built a canal with a dam in order to bring the water of the Reuss to the millwheel in a more regulated manner. In 1869, the Zurich Mechanical Silk Weaving Mill (owned by Bodmer & Hürlimann) bought the former mill from Hein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ottenbach, Switzerland
Ottenbach is a municipality in the district of Affoltern in the canton of Zürich in Switzerland. History Ottenbach is first mentioned in 831 as ''in loco vocato marcha Hotumbacharia''. In 1169 it was mentioned as ''Arnoldus de Ottonbac''. Since the end of the 18th century, the textile industry had expanded as a home industry (Putting-out system) in Ottenbach: In 1784, the cotton spinning mill employed 49% of the local population (430 people, 287 of whom worked all year round). At the beginning of the 19th century there were around 350 weaving looms and the Zurich Mechanical Silk Weaving Mill employed more than 200 people in Ottenbach from the village and the surrounding area. Geography Ottenbach has an area of . Of this area, 56.4% is used for agricultural purposes, while 20.7% is forested. Of the rest of the land, 19.1% is settled (buildings or roads) and the remainder (3.8%) is non-productive (rivers, glaciers or mountains). It is located near the Reuss River on the b ...

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.

Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units, International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Energy transformation, energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish people, Scottish invention, inventor, mechanical engineer, and chemist who improved the Newcomen steam engine, Newcomen engine with his own Watt steam engine, 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 (unit), newton, the rate at which Work (physics), 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 potentia ...

Reuss (river)
The Reuss (Swiss German: ''Rüüss'') is a river in Switzerland. With a length of and a drainage basin of , it is the fourth largest river in Switzerland (after the Rhine, Aare and Rhône). The upper Reuss forms the main valley of the canton of Uri. The course of the lower Reuss runs from Lake Lucerne to the confluence with the Aare at Brugg and Windisch. The Reuss is one of the four major rivers taking their source in the Gotthard region, along with the Rhine, Ticino and Rhône. Geography Course The Gotthardreuss rises in the Gotthard massif, emerging from Lago di Lucendro (reservoir built in 1947; elevation 2,131 m) in the canton of Ticino and passing into the canton of Uri below the ''Brigghubel'' (1,898 m). The Furkareuss rises east of Furka Pass (2,429 m), early joined by the ''Blaubergbach'' (sourced by two mountain lakes on 2,649 m) and several other creeks sourced by still existing glaciers, such as ''Sidelengletscher'' (3,170 m) ...

Gottfried Keller
Gottfried Keller (19 July 1819 – 15 July 1890) was a Swiss poet and writer of German literature. Best known for his novel '' Green Henry'' (German: ''Der grüne Heinrich'') and his cycle of novellas called ''The People from Seldwyla'' (''Die Leute von Seldwyla''), he became one of the most popular narrators of literary realism in the late 19th century. Early life His father was Rudolf Keller (1791–1824), a lathe-worker from Glattfelden; his mother was a woman named Elisabeth Scheuchzer (1787–1864). The couple had six children, four of whom died, meaning Keller only had his sister Regula (*1822) left. After his father died of tuberculosis, Keller's family lived in constant poverty, and, because of Keller's difficulties with his teachers, in continual disagreement with school authorities. Keller later gave a good rendering of his experiences in this period in his long novel, ''Der grüne Heinrich'' (1850–55; 2nd version, 1879). His mother seems to have brought him up in as ca ...

Jonval Turbine
The Jonval turbine is a water turbine design invented in France in 1837 and introduced to the United States around 1850 and were widely used. The Jonval turbine is a "mixed-flow" turbine design. Mixed-flow designs were well suited for the low-head applications common in the eastern United States. The smaller size, higher speed, higher power, lower cost, and ability to operate efficiently with variable water levels caused these and other types of hydraulic turbines to replace the vertical waterwheel as the primary source of power in American industries. The Jonval turbine is a horizontal waterwheel. The water descends through fixed curved guide vanes which direct the flow sideways onto curved vanes on the runner. It is named after Feu Jonval, who invented it. The Jonval incorporated ideas from European mathematicians and engineers, including the use of curved blades. This new turbine failed to satisfy the public interest in seeing the water wheels in action, which was likely accepte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Turbine
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines radial and axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. It became known as the Francis turbine around 1920, being named after British-American engineer James B. Francis who in 1848 created a new turbine design. Francis turbines are primarily used for producing electricity. The power output of the electric generators generally ranges from just a few kilowatts up to 1000 MW, though mini-hydro installations may be lower. The best performance is seen when the head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm. A wicket gate around the outside of the turbine's rotating runner controls the rate of water flow through the turbine for d ...

Brown, Boveri & Cie
Brown, Boveri & Cie. (Brown, Boveri & Company; BBC) was a Swiss group of electrical engineering companies. It was founded in Zürich, in 1891 by Charles Eugene Lancelot Brown and Walter Boveri who worked at the Maschinenfabrik Oerlikon. In 1970 BBC took over the Maschinenfabrik Oerlikon. In 1988 it merged with ASEA to form ABB. Early History of BBC Brown Boveri BBC Brown Boveri was established in 1891. The company was one of only a few multinational corporations to operate subsidiaries that were larger than the parent company. Because of the limitations of the Swiss domestic market, Brown Boveri established subsidiaries throughout Europe relatively early in its history, and at times had difficulty maintaining managerial control over some of its larger operating units. The merger with ASEA, a company which was praised for its strong management, was expected to help Brown Boveri reorganize and reassert control over its vast international network.

Art Deco
Art Deco, short for the French ''Arts Décoratifs'', and sometimes just called Deco, is a style of visual arts, architecture, and product design, that first appeared in France in the 1910s (just before World War I), and flourished in the United States and Europe during the 1920s and 1930s. Through styling and design of the exterior and interior of anything from large structures to small objects, including how people look (clothing, fashion and jewelry), Art Deco has influenced bridges, buildings (from skyscrapers to cinemas), ships, ocean liners, trains, cars, trucks, buses, furniture, and everyday objects like radios and vacuum cleaners. It got its name after the 1925 Exposition internationale des arts décoratifs et industriels modernes (International Exhibition of Modern Decorative and Industrial Arts) held in Paris. Art Deco combined modern styles with fine craftsmanship and rich materials. During its heyday, it represented luxury, glamour, exuberance, and faith in socia ...
