Archimedes Screw Turbine
Reverse action of the Archimedean screw, the principle of the screw turbine gaining energy from water flowing down through the screw Screw turbines typically have three or four flights (second row) Two parallel screw turbines capable of producing 75 kW each, in Monmouth, South Wales Video of a 40 kW screw turbine in Munich, Germany A screw turbine (also known as an Archimedean turbine, Archimedes screw generator or ASG, or Archimedes screw turbine or AST) is a water turbine 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. Archimedes' screw can be use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archimedes Of Syracuse
Archimedes of Syracuse ( ; ) was an Ancient Greek mathematician, physicist, engineer, astronomer, and inventor from the ancient city of Syracuse in Sicily. Although few details of his life are known, based on his surviving work, he is considered one of the leading scientists in classical antiquity, and one of the greatest mathematicians of all time. Archimedes anticipated modern calculus and analysis by applying the concept of the infinitesimals and the method of exhaustion to derive and rigorously prove many geometrical theorems, including the area of a circle, the surface area and volume of a sphere, the area of an ellipse, the area under a parabola, the volume of a segment of a paraboloid of revolution, the volume of a segment of a hyperboloid of revolution, and the area of a spiral. Archimedes' other mathematical achievements include deriving an approximation of pi (), defining and investigating the Archimedean spiral, and devising a system using exponentiation for ex ...

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 National Landscape (to the north of Honiton) and East Devon National Landscap ...

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 Germany, officially the Federal Republic of Germany, is a country in Central Europe. It lies between the Baltic Sea and the North Sea to the north and the Alps to the south. Its sixteen States of German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

River Dart
The River Dart is a river in Devon, England, that source (river), rises high on Dartmoor and flows for to the sea at Dartmouth, Devon, Dartmouth. Name Most hydronyms in England derive from the Common Brittonic, Brythonic language (from which the river's subsequent names ultimately derive from an original Celtic languages, 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 , meaning 'oak' (, ). However the second element (evident in the hard consonantal termination of ''Dar-t'') is less certain, with postulated etymologies from / ('sacred place of oak') or / ('oak stream'). The Ravenna Cosmography records a number of Latinisation of names, Latinised names for the area, and may represent corrupted doublets of a ('station') on a river named . Although the name is otherwise unattested for the river, it is an established etymology throughout Britain, found at the River Darent, ...

River Mersey
The River Mersey () is a major river in North West England. Its name derives from Old English and means "boundary river", possibly referring to its having been a border between the ancient kingdoms of Mercia and Northumbria. For centuries it has formed part of the boundary between the historic counties of Lancashire and Cheshire. The Mersey starts at the confluence of the River Tame and River Goyt in Stockport. It flows westwards through south Manchester, then into the Manchester Ship Canal near Irlam Locks, becoming a part of the canal and maintaining its water levels. After it exits the canal, flowing towards Warrington where it widens. It then narrows as it passes between Runcorn and Widnes. The river widens into a large estuary, which is across at its widest point near Ellesmere Port. The course of the river then turns northwards as the estuary narrows between Liverpool and Birkenhead on the Wirral Peninsula to the west, and empties into Liverpool Bay. In total the ...
