A stave is a narrow length of wood with a slightly bevelled edge to form the sides of barrels, tanks, tubs, vats and pipelines, originally handmade by coopers. [1] They have been used in the construction of large holding tanks and penstocks at hydro power developments. [2] They are also used in the construction of certain musical instruments with rounded bodies or backs. [3] [4]
Carpentry is a skilled trade and a craft in which the primary work performed is the cutting, shaping and installation of building materials during the construction of buildings, ships, timber bridges, concrete formwork, etc. Carpenters traditionally worked with natural wood and did rougher work such as framing, but today many other materials are also used and sometimes the finer trades of cabinetmaking and furniture building are considered carpentry. In the United States, 98.5% of carpenters are male, and it was the fourth most male-dominated occupation in the country in 1999. In 2006 in the United States, there were about 1.5 million carpentry positions. Carpenters are usually the first tradesmen on a job and the last to leave. Carpenters normally framed post-and-beam buildings until the end of the 19th century; now this old-fashioned carpentry is called timber framing. Carpenters learn this trade by being employed through an apprenticeship training—normally 4 years—and qualify by successfully completing that country's competence test in places such as the United Kingdom, the United States, Canada, Switzerland, Australia and South Africa. It is also common that the skill can be learned by gaining work experience other than a formal training program, which may be the case in many places.
A joiner is an artisan and tradesperson who builds things by joining pieces of wood, particularly lighter and more ornamental work than that done by a carpenter, including furniture and the "fittings" of a house, ship, etc. Joiners may work in a workshop, because the formation of various joints is made easier by the use of non-portable, powered machinery, or on job site. A joiner usually produces items such as interior and exterior doors, windows, stairs, tables, bookshelves, cabinets, furniture, etc. In shipbuilding a marine joiner may work with materials other than wood such as linoleum, fiberglass, hardware, and gaskets.
The Clyde Dam, New Zealand's third largest hydroelectric dam, is built on the Clutha River near the town of Clyde. It is owned and operated by Contact Energy.
A barrel or cask is a hollow cylindrical container with a bulging center, longer than it is wide. They are traditionally made of wooden staves and bound by wood or metal hoops. The word vat is often used for large containers for liquids, usually alcoholic beverages; a small barrel or cask, typically with capacity of not more than ten gallons, is known as a keg.
The Grande Dixence Dam is a concrete gravity dam on the Dixence at the head of the Val d'Hérémence in the canton of Valais in Switzerland. At 285 m (935 ft) high, it is the tallest gravity dam in the world, fifth tallest dam overall, and the tallest dam in Europe. It is part of the Cleuson-Dixence Complex. With the primary purpose of hydroelectric power generation, the dam fuels four power stations, totaling the installed capacity to 2,069 MW, generating approximately 2,000 GWh annually, enough to power 400,000 Swiss households.
Canada Water is an area of the Docklands in south-east London. It is named after a freshwater lake and wildlife refuge. Canada Water tube, Overground and bus station is immediately north of the lake, along with Canada Water Library which overhangs the lake and Deal Porter Square. Surrey Quays Shopping Centre is also adjacent, sitting immediately to the south. The surrounding area, which forms the town centre of Rotherhithe, is now increasingly known as Canada Water, after the transport interchange as much as the lake itself.
A penstock is a sluice or gate or intake structure that controls water flow, or an enclosed pipe that delivers water to hydro turbines and sewerage systems. The term is inherited from the earlier technology of mill ponds and watermills.
The Lake Margaret Power Stations comprise two hydroelectric power stations located in Western Tasmania, Australia. The power stations are part of the King – Yolande Power Scheme and are owned and operated by Hydro Tasmania. Officially the Upper Lake Margaret Power Station, a conventional hydroelectric power station, and the Lower Lake Margaret Power Station, a mini-hydroelectric power station, the stations are generally collectively referred to in the singular format as the Lake Margaret Power Station. The stations are located approximately 2.5 kilometres (1.6 mi) apart.
The Petty Harbour Hydro Electric Generating Station is a hydroelectric generating station in Petty Harbour–Maddox Cove, Newfoundland and Labrador. It was constructed in 1898 and it was the first hydroelectric generating station in Newfoundland. It was built by the St. John's Street Railway Company, a company established by Robert Reid. Operation commenced on 19 April 1900.
The Poatina Power Station is a conventional hydroelectric power station located in the Central Highlands region of Tasmania, Australia. The power station is situated on the Great Lake and South Esk and is owned and operated by Hydro Tasmania.
The baglamas or baglamadaki (μπαγλαμαδάκι), a long necked bowl-lute, is a plucked string instrument used in Greek music; it is a smaller version of the bouzouki pitched an octave higher, with unison pairs on the four highest strings and an octave pair on the lower D. Musically, the baglamas is most often found supporting the bouzouki in the Piraeus city style of rebetiko.
Alouette Lake, originally Lillooet Lake and not to be confused with the lake of that name farther north, is a lake and reservoir in Maple Ridge, British Columbia, Canada. It is located at the southeast foot of the mountain group known as the Golden Ears and is about 16 km in length on a northeast–southwest axis. It and the Alouette River, formerly the Lillooet River, were renamed in 1914 to avoid confusion with the larger river and lake farther north, with "Alouette", the French word for "lark", being chosen as being melodious and reminiscent of the original name in tone.
Atiamuri Power Station is a hydroelectric power station on the Waikato River, in the North Island of New Zealand. It is the third of eight hydroelectric power stations on the Waikato River. The station can easily be seen from State Highway 1 between Taupo and Tokoroa.
Caliraya Dam is an embankment dam located in the town of Lumban province of Laguna, in the Sierra Madre Mountain Range of the Philippines. The reservoir created by the dam, Lake Caliraya, initially supplied one of the oldest hydroelectric plants in the Philippines, and later became a popular recreational area for numerous water sports and fishing. The dam's construction was started in 1939 under the supervision of the architecture firm of Pedro Siochi and Company and a small hydroelectric plant was operated in 1942.
Cloudworks Energy Inc. was a private, Vancouver-based run-of-river hydro developer formed in 1999. The firm's principals developed the 33MW Miller Creek run-of-river project and the 49.9MW Rutherford Creek project. In 2011 Innergex Renewable Energy acquired Cloudworks Energy Inc.
Ruskin Dam is a concrete gravity dam on the Stave River in Ruskin, British Columbia, Canada. The dam was completed in 1930 for the primary purpose of hydroelectric power generation. The dam created Hayward Lake, which supplies water to a 105 MW powerhouse and flooded the Stave's former lower canyon, which ended in a small waterfall approximately where the dam is today.
Stave Falls Dam is a dual-dam power complex on the Stave River in Stave Falls, British Columbia, Canada. The dam was completed in 1912 for the primary purpose of hydroelectric power production. To increase the capacity of Stave Lake, the dam was raised in 1925 and the Blind Slough Dam constructed in an adjacent watercourse 500 m (1,600 ft) to the north, which was the site of the eponymous Stave Falls. In 2000, the dam's powerhouse was replaced after a four-year upgrade. The powerhouse was once British Columbia's largest hydroelectric power source and is a National Historic Site of Canada.
The John Hart Dam is one of three hydroelectric dams on the Campbell River, located on Vancouver Island in British Columbia, Canada. The dam is located at the outflow of John Hart Lake. The John Hart Generating Station is located nearby.
The St. Margaret's Bay Hydroelectric System consists of three hydroelectric power plants and the related lake, dam, and river systems driving them.
