Hydropower, also known as water power, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively consistent source of power. Nonetheless, it has economic, sociological, and environmental downsides and requires a sufficiently energetic source of water, such as a river or elevated lake. International institutions such as the World Bank view hydropower as a low-carbon means for economic development.
A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work.
Guildford is a town in west Surrey, England, around 27 mi (43 km) southwest of central London. As of the 2011 census, the town has a population of about 77,000 and is the seat of the wider Borough of Guildford, which had around 143,650 inhabitants in mid-2019 est.. The name "Guildford" is thought to derive from a crossing of the River Wey, a tributary of the River Thames that flows through the town centre.
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.
Godalming is a market town and civil parish in southwest Surrey, England, around 30 mi (48 km) southwest of central London. It is in the Borough of Waverley, at the confluence of the Rivers Wey and Ock. The civil parish covers 3.74 sq mi (9.7 km2) and includes the settlements of Farncombe, Binscombe and Holloway Hill. Much of the area lies on the strata of the Lower Greensand Group and Bargate stone was quarried locally until the Second World War.
Shalford is a village and civil parish in Surrey, England on the A281 Horsham road immediately south of Guildford. It has a railway station which is between Guildford and Dorking on the Reading to Gatwick Airport line.
Micro hydro is a type of hydroelectric power that typically produces from 5 kW to 100 kW of electricity using the natural flow of water. Installations below 5 kW are called pico hydro. These installations can provide power to an isolated home or small community, or are sometimes connected to electric power networks, particularly where net metering is offered. There are many of these installations around the world, particularly in developing nations as they can provide an economical source of energy without the purchase of fuel. Micro hydro systems complement solar PV power systems because in many areas water flow, and thus available hydro power, is highest in the winter when solar energy is at a minimum. Micro hydro is frequently accomplished with a pelton wheel for high head, low flow water supply. The installation is often just a small dammed pool, at the top of a waterfall, with several hundred feet of pipe leading to a small generator housing. In low head sites, generally water wheels and Archimedes' screws are used.
Mapledurham Watermill is a historic watermill in the civil parish of Mapledurham in the English county of Oxfordshire. It is driven by the head of water created by Mapledurham Lock and Weir, on the River Thames. The mill was built in the 15th century, and further extended in the 17th, 18th and 19th centuries. It is a Grade II* listed building and is preserved in an operational state.
The Yvonne Arnaud Theatre is a theatre located in Guildford, Surrey, England. Named after the actress Yvonne Arnaud, it presents a series of locally produced and national touring productions, including opera, ballet and pantomime. The theatre has two performance venues, the main auditorium and the smaller Mill Studio.
The River Wey Navigation and Godalming Navigation together provide a 20-mile (32 km) continuous navigable route from the River Thames near Weybridge via Guildford to Godalming. Both waterways are in Surrey and are owned by the National Trust. The River Wey Navigation connects to the Basingstoke Canal at West Byfleet, and the Godalming Navigation to the Wey and Arun Canal near Shalford. The Navigations consist of both man-made canal cuts and adapted parts of the River Wey.
Gomshall is a village in the borough of Guildford in Surrey, England.
Old Woking is a ward and the original settlement of the town and borough of Woking, Surrey, about 1.3 miles (2.1 km) southeast of the modern town centre. It is bounded by the Hoe Stream to the north and the River Wey to the south and between Kingfield to the west and farmland to the east. The village has no dual carriageways or motorways, its main road is the A247, which connects Woking with Clandon Park and provides access to the A3. The village contains parts of Woking's two largest parks and two converted paper mills. The expanded village largely consists of semi-detached houses with gardens and covers an area of 224 hectares
Pico hydro is a term used for hydroelectric power generation of under 5 kW. These generators have proven to be useful in small, remote communities that require only a small amount of electricity – for example, to power one or two fluorescent light bulbs and a TV or radio in 50 or so homes. Even smaller turbines of 200–300 W may power a single home with a drop of only 1 metre (3.3 ft). Pico-hydro setups typically are run-of-stream, meaning that a reservoir of water is not created, only a small weir is common, pipes divert some of the flow, drop this down a gradient, and through the turbine before being exhausted back to the stream.
Dapdune Wharf is a former industrial wharf and boat yard on the Wey and Godalming Navigations in Guildford, England, UK, close to the Surrey County Cricket Club ground. It is now maintained by the National Trust.
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.
Gants Mill is a watermill on the River Brue in Pitcombe near Bruton, Somerset, England.
Sir Richard Arkwright's Masson Mill is a water-powered cotton spinning mill situated on the west bank of the River Derwent in Matlock Bath, Derbyshire in England. This mill was built in 1783. It forms part of the Derwent Valley Mills, a World Heritage Site. Nearby is Willersley Castle, the house Richard Arkwright built for himself within the parish of Matlock.
Coxes Lock is towards the northern end of the Wey Navigation parallel to the River Wey in Addlestone, Surrey,
Stoke Mill is a 19th century corn mill on the River Wey that has been converted into offices. It is situated off the Woking Road just north of Guildford town centre. It forms the centrepiece of a small group of buildings that includes the Grade II listed Stoke Mill House.
Many watermills lined the banks of the River Wey, England, from the 17th century due to the river's ability to provide a reliable, year-round flow of water. These mills chiefly ground wheat, often referred to as corn, for flour and oats for animal feed though many were used in the production of other goods such as paper, cloth, leather, wire and gunpowder. The river was home to more mills per mile than anywhere else in Great Britain. The mill situated at Coxes Lock near Addlestone, Surrey, is the largest. There are many mills on the river's principal tributaries, such as the Tillingbourne, the Ock and some mills on the Whitmore Vale stream, Cranleigh Waters and Hodge Brook. The last commercial mill on the Tillingbourne, Botting's Mill at Albury, closed in 1991. Headley Water Mill, on the Wey South branch is still in business. Town Mill, Guildford still has a water turbine driven generator producing electricity for the town.
