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. 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 screw turbines act 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.
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.
Llechryd is a rural village on the A484 road approximately 3 miles (4.8 km) from Cardigan, Ceredigion, Wales. Situated on the north bank of the tidal River Teifi, Llechryd is the first point upstream of Cardigan where crossing is possible. Most of the village has developed along the A484, with some estates branching off into the valley.
A mill race, millrace or millrun, mill lade (Scotland) or mill leat is the current of water that turns a water wheel, or the channel (sluice) conducting water to or from a water wheel. Compared with the broad waters of a mill pond, the narrow current is swift and powerful. The race leading to the water wheel on a wide stream or mill pond is called the head race, and the race leading away from the wheel is called the tail race.
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.
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.
The Land Yeo is a small river which flows through North Somerset, England. It rises on Dundry Hill and supplies Barrow Gurney Reservoirs before flowing through various villages to Clevedon where it drains into the Severn Estuary. During the past 1,000 years it has powered at least ten watermills, however only one is still functional. Since 2003 initiatives have been undertaken to clean up the river, improving water quality and encouraging wildlife.
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.
Monnow Mill is a former watermill on the river Monnow in Osbaston on the Osbaston road in Monmouth, Wales. The building is now a private house. The mill was once known as Queens Mills. The building has been a Grade II Listed since 1974.
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.
Burley Hydro Scheme, also known as Greenholme Mill Hydro is a micro hydroelectric scheme installed on the River Wharfe at Burley-in-Wharfedale, West Yorkshire, England. The power output of the hydro scheme is 330 kW with an annual output of 1,400 MWh and is the fourth hydro scheme on the river after the opening of similar power plants at Linton near Grassington, and two further downstream from Burley at Pool-in-Wharfedale and Garnett Wharfe at Otley. All of these schemes have been located on sites previously used to generate power from the water flow.
