Screw Turbine
Archimedes Screw Generator (ASG), also known as Archimedes/Archimedean Screw Turbine (AST), Archimedean turbine or screw turbine is a hydraulic machine that converts the potential energy of water on an upstream level into work. This hydropower converter is driven by the weight of water, similar to water wheels, and can be considered as a quasi-static pressure machine. Archimedes screw generators operate in a wide range of flows (0.01 m^3/s to 14.5 m^3/s) and heads (0.1 m to 10 m), including low heads and moderate flow rates that are not ideal for traditional turbines and not occupied by high performance technologies. The length of the smallest and longest Archimedes screw generators are 1 m an 30 m respectively. Archimedes screws can be used to generate power if they are driven by flowing fluid instead of lifting fluid. Water transiting the screw from high to low elevation generates a torque on the helical plane surfaces, causing the screw to rotate. The Archimedes screw gen ...

Water Turbine
A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation. Water turbines are mostly found in dams to generate electric power from water potential energy. History Water wheels have been used for hundreds of years for industrial power. Their main shortcoming is size, which limits the flow rate and head that can be harnessed. The migration from water wheels to modern turbines took about one hundred years. Development occurred during the Industrial revolution, using scientific principles and methods. They also made extensive use of new materials and manufacturing methods developed at the time. Swirl The word turbine was introduced by the French engineer Claude Burdin in the early 19th century and is derived from the Greek word "τύρβη" ...

Quinnipiac River
The Quinnipiac River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed April 1, 2011 long river in the New England region of the United States, located entirely in the state of Connecticut. The river rises in West Central Connecticut from Dead Wood Swamp near the city of New Britain. It flows roughly southward to Plainville, Southington, and Cheshire, west of the city of Meriden, through Wallingford and Yalesville, North Haven, and flows into New Haven Harbor, an inlet of Long Island Sound, east of downtown New Haven. History The name "Quinnipiac" comes from an Algonquian phrase meaning "long water land", and historically referred both to the river and the area around its mouth at Long Island Sound. Europeans found the river in 1614. By the early 18th century, early settlers called the Quinnipiac River the Dragon River after the seals, then referred to as “sea dragons,” that were once abundant there. A ...

Cragside
Cragside is a Victorian country house near the town of Rothbury in Northumberland, England. It was the home of William Armstrong, 1st Baron Armstrong, founder of the Armstrong Whitworth armaments firm. An industrial magnate, scientist, philanthropist and inventor of the hydraulic crane and the Armstrong gun, Armstrong also displayed his inventiveness in the domestic sphere, making Cragside the first house in the world to be lit using hydroelectric power. The estate was technologically advanced; the architect of the house, Richard Norman Shaw, wrote that it was equipped with "wonderful hydraulic machines that do all sorts of things". In the grounds, Armstrong built dams and lakes to power a sawmill, a water-powered laundry, early versions of a dishwasher and a dumb waiter, a hydraulic lift and a hydroelectric rotisserie. In 1887, Armstrong was raised to the peerage, the first engineer or scientist to be ennobled, and became Baron Armstrong of Cragside. The original buildi ...

Rochdale
Rochdale ( ) is a large town in Greater Manchester, England, at the foothills of the South Pennines in the dale on the River Roch, northwest of Oldham and northeast of Manchester. It is the administrative centre of the Metropolitan Borough of Rochdale, which had a population of 211,699 in the 2011 census. Located within the historic boundaries of the county of Lancashire. Rochdale's recorded history begins with an entry in the Domesday Book of 1086 under "Recedham Manor". The ancient parish of Rochdale was a division of the hundred of Salford and one of the largest ecclesiastical parishes in England, comprising several townships. By 1251, Rochdale had become important enough to have been granted a Royal charter. Rochdale flourished into a centre of northern England's woollen trade, and by the early 18th century was described as being "remarkable for many wealthy merchants". Rochdale rose to prominence in the 19th century as a mill town and centre for textile manufactur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Otter, Devon
The River Otter is a river that rises in the Blackdown Hills just inside the county of Somerset, England near Otterford, then flows south through East Devon. It enters the English Channel at the western end of Lyme Bay, part of the Jurassic Coast, a UNESCO World Heritage Site. The Permian and Triassic sandstone aquifer in the Otter Valley is one of Devon's largest groundwater sources, supplying drinking water to 200,000 people. Topography The river's source is north of Otterford, where a stream feeds the Otterhead Lakes: and then through Churchstanton before entering Devon. The river flows through a predominantly rural area, with small cattle, sheep and dairy farms. The largest town in the Otter Valley is Honiton. Tourism and leisure play important roles in the economy. For much of its length, the river flows through two Areas of Outstanding Natural Beauty (AONBs) – The Blackdown Hills AONB (to the north of Honiton) and East Devon AONB (to the south of Ottery St Mary ...

River Bain Hydro
The River Bain Hydro is a hydroelectric generator on the River Bain in the village of Bainbridge, North Yorkshire, England. Its screw turbine powers most of the properties in the village, with excess electricity being sold off to the National Grid. It was opened in 2011 with an installed capacity of 45 kW, and is expected to last 40 years. It is a low-demand ecofriendly scheme. History A hydro-power plant had been in existence on the site since the late 19th century. Like the new scheme, this was locally run but was wound up (as Bainbridge Electricity Supply) in 1953 when the National Grid took over supplying power to the area. The new plant was built between 2010 and 2011, with the long Archimedes screw being brought in from a specialist engineering firm in Germany. The plant, which was funded by a grant, a bank loan and a public share issue and cost £450,000 to build, opened in May 2011 and supplies enough power for 40 homes in the village of Bainbridge. The plant is e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

River Dart
The River Dart is a river in Devon, England, that rises high on Dartmoor and flows for to the sea at Dartmouth. Name Most hydronyms in England derive from the Brythonic language (from which the river's subsequent names ultimately derive from an original Celtic etymology. As the lower stretches of the river are still covered in ancient oak woodlands, it is accepted that the first element derives from *Dar-, meaning oak (derow'', Welsh ''derw''). However the second element (evident in the hard consonantal termination of ''Dar-t'') is less certain, with postulated etymologies from ''Darwent'' / ''Derventio'' (Sacred place of Oak) or ''Darnant'' / ''Darant'' (Oak stream). The Ravenna Cosmography records a number of Latinised names for the area, ''Devionisso Statio'' and ''Deventiasteno'' may represent corrupted doublets of a ''Statio'' (Station) on a river named ''Derventio''. Although the name ''Derventio'' is otherwise unattested for the river, it is an established etymolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Thames
The River Thames ( ), known alternatively in parts as the River Isis, is a river that flows through southern England including London. At , it is the longest river entirely in England and the second-longest in the United Kingdom, after the River Severn. The river rises at Thames Head in Gloucestershire, and flows into the North Sea near Tilbury, Essex and Gravesend, Kent, via the Thames Estuary. From the west it flows through Oxford (where it is sometimes called the Isis), Reading, Henley-on-Thames and Windsor. The Thames also drains the whole of Greater London. In August 2022, the source of the river moved five miles to beyond Somerford Keynes due to the heatwave in July 2022. The lower reaches of the river are called the Tideway, derived from its long tidal reach up to Teddington Lock. Its tidal section includes most of its London stretch and has a rise and fall of . From Oxford to the Estuary the Thames drops by 55 metres. Running through some of the drier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
