Oxfordshire is a ceremonial county in South East England. The county is bordered by Northamptonshire and Warwickshire to the north, Buckinghamshire to the east, Berkshire to the south, and Wiltshire and Gloucestershire to the west. The city of Oxford is the largest settlement and county town.
The Archimedes' screw, also known as the Archimedean screw, hydrodynamic screw, water screw or Egyptian screw, is one of the earliest hydraulic machines. Using Archimedes screws as water pumps dates back many centuries. Because it can not generate pressure it is not a pump. As a machine used for lifting water from a low-lying body of water into irrigation ditches, water is lifted by turning a screw-shaped surface inside a pipe. In the modern world, Archimedes screw pumps are widely used in wastewater treatment plants and for dewatering low-lying regions. Run in reverse, Archimedes screws turbine acts as a new form of small hydroelectric powerplant that can be applied even in low head sites. Such generators operate in a wide range of flows and heads, including low heads and moderate flow rates that is not ideal for traditional turbines and not occupied by high performance technologies. The Archimedes screw is a reversible hydraulic machine, and there are several examples of Archimedes screw installations where the screw can operate at different times as either pump or generator, depending on needs for power and watercourse flow.
A watermill or water mill is a mill that uses hydropower. It is a structure that uses a water wheel or water turbine to drive a mechanical process such as milling (grinding), rolling, or hammering. Such processes are needed in the production of many material goods, including flour, lumber, paper, textiles, and many metal products. These watermills may comprise gristmills, sawmills, paper mills, textile mills, hammermills, trip hammering mills, rolling mills, wire drawing mills.
A water wheel is a machine for converting the energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a wheel, with a number of blades or buckets arranged on the outside rim forming the driving car. Water wheels were still in commercial use well into the 20th century but they are no longer in common use. Uses included milling flour in gristmills, grinding wood into pulp for papermaking, hammering wrought iron, machining, ore crushing and pounding fibre for use in the manufacture of cloth.
Caversham is a suburb of Reading, England, located directly north of the town centre across the River Thames. Caversham rises from the River Thames, lying on flood plain and the lowest reaches of the Chiltern Hills. Two road bridges, including Caversham Bridge, and two footbridges join Caversham to the rest of Reading. Named areas within the suburb include Emmer Green, Lower Caversham, Caversham Heights and Caversham Park Village. Notable landmarks include Caversham Court, a public park and former country house; Caversham Lakes; and part of the Thames Path national trail.
The Darent is a Kentish tributary of the River Thames and takes the waters of the River Cray as a tributary in the tidal portion of the Darent near Crayford. 'Darenth' is frequently found as the spelling of the river's name in older books and maps, Bartholomew's Canals and River of England being one example. Bartholomew's Gazetteer (1954) demonstrates that Darent means "clear water", a result of it springing from and running through chalk. The purity of the water was a major factor in the development of paper and pharmaceuticals in the area.
Bromham is a village and civil parish in the Borough of Bedford in Bedfordshire, England, situated around 3 miles (4.8 km) west of Bedford town centre.
The River Loddon is a tributary of the River Thames in southern England. It rises at Basingstoke in Hampshire and flows northwards for 28 miles (45 km) to meet the Thames at Wargrave in Berkshire. Together, the Loddon and its tributaries drain an area of 400 square miles (1,036 km2).
Mapledurham Lock is a lock and weir situated on the River Thames in England, about 4 miles upstream of Reading. The lock was first built in 1777 by the Thames Navigation Commissioners and the present lock dates from 1908.
Sonning Eye is a hamlet on the River Thames in the Sonning Common ward of South Oxfordshire, England, in the civil parish of Eye & Dunsden, at what is since 1974 the southernmost tip of Oxfordshire.
Mapledurham is a small village, civil parish and country estate beside the River Thames in southern Oxfordshire, England. The large parish borders Caversham, the most affluent major district of Reading, Berkshire. Historic buildings in the area include the Church of England parish church of St. Margaret, Mapledurham Watermill and Mapledurham House.
Dunster Working Watermill is a restored 18th century watermill, situated on the River Avill, close to Gallox Bridge, in the grounds of Dunster Castle in Dunster, Somerset, England. It is a Grade II* listed building and within the Grade II* registered parkland of the castle.
Mapledurham House is an Elizabethan stately home located in the civil parish of Mapledurham in the English county of Oxfordshire. It is a Grade I listed building, first listed on 24 October 1951.
Buxton Mill, is located on the River Bure about 0.5 miles (0.80 km) east of the village of Buxton, Norfolk, and is in the hamlet of Lamas, Norfolk. A watermill was recorded here in the Domesday Book. The present mill is thought to date from 1754 and was built by William Pepper, a merchant living in Buxton.
Howsham Mill is a Grade II listed 18th century watermill located on the River Derwent in North Yorkshire, England.
The Bybrook, also known as the By Brook, is a small river in England. It is a tributary of the Bristol Avon and is some 12 miles (19 km) long. Its sources are the Burton Brook and the Broadmead Brook, which rise in South Gloucestershire at Tormarton and Cold Ashton respectively, and join just north of Castle Combe in Wiltshire. The river has a mean flow rate of 57.25 cubic feet per second (1.621 m3/s) as recorded at Middlehill near Box. A variety of flora and fauna is supported by the river including the endangered white-clawed crayfish. Twenty watermill sites have been identified on the river but none now remain in use.
Reading's location in the Thames Valley at the confluence of the River Thames and River Kennet, and on both the Great Western Main Line and the M4 motorway, some 40 miles (64 km) west of London has made the town an important location in the nation's transport system.
Osbaston is a suburb of Monmouth, Wales, located less than 1 mile (1.6 km) north of the town centre. It was the site of one of the first public electricity generating stations in Britain, using water power from the River Monnow.
A screw turbine is 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 and heads, including low heads and moderate flow rates that are not ideal for traditional turbines and not occupied by high performance technologies.
Sandford Hydro is a small hydroelectric scheme located on the River Thames in Oxfordshire, England. It uses the head of water provided by the weir at Sandford Lock in Sandford-on-Thames, but is actually situated on the opposite bank of the river in Kennington. It can generate 450 kilowatts (600 hp) of electricity with its three archimedes screw turbines. Construction began in 2011, and the plant became operational in 2018.
