A windmill is a structure that converts wind power into rotational energy using vanes called sails or blades, by tradition specifically to mill grain ( gristmills ), but in some parts of the English-speaking world, the term has also been extended to encompass windpumps , wind turbines , and other applications. The term wind engine is also sometimes used to describe such devices.
113-537: Abergele Welsh: [ˌabɛrˈɡɛlɛ] ; pronunciation ) is a market town and community , situated on the north coast of Wales between the holiday resorts of Colwyn Bay and Rhyl , in Conwy County Borough and in the historic county of Denbighshire . Its northern suburb of Pensarn lies on the Irish Sea coast. Abergele and Pensarn railway station serves both resorts. Abergele
226-440: A community space on the upper floor. The oldest surviving structures date from the mid-17th century. In Scotland, borough markets were held weekly from an early stage. A King's market was held at Roxburgh on a specific day from about the year 1171; a Thursday market was held at Glasgow , a Saturday market at Arbroath , and a Sunday market at Brechin . In Scotland, market towns were often distinguished by their mercat cross :
339-514: A crossing-place on the River Thames up-river from Runnymede , where it formed an oxbow lake in the stream. Early patronage included Thomas Furnyvale, lord of Hallamshire , who established a Fair and Market in 1232. Travelers were able to meet and trade wares in relative safety for a week of "fayres" at a location inside the town walls. The reign of Henry III witnessed a spike in established market fairs. The defeat of de Montfort increased
452-528: A crossroads or close to a river ford , for example, Cowbridge in the Vale of Glamorgan. When local railway lines were first built, market towns were given priority to ease the transport of goods. For instance, in Calderdale , West Yorkshire , several market towns close together were designated to take advantage of the new trains. The designation of Halifax , Sowerby Bridge , Hebden Bridge , and Todmorden

At the municipal reform of 1970 , market towns were merged with neighboring parishes, and the market towns lost their special status and privileges, though many still advertise themselves using the moniker of købstad and hold public markets on their historic market squares . The medieval right to hold markets ( German : Marktrecht )
678-559: A good deal is known about the economic value of markets in local economies, the cultural role of market-towns has received scant scholarly attention. In Denmark, the concept of the market town ( Danish : købstad ) emerged during the Iron Age. It is not known which was the first Danish market town, but Hedeby (part of modern-day Schleswig-Holstein ) and Ribe were among the first. As of 1801, there were 74 market towns in Denmark (for

Their long-lasting feudal subordination to landowners or the church is also a crucial difference. The successors of these settlements usually have a distinguishable townscape. The absence of fortification walls, sparsely populated agglomerations, and their tight bonds with agricultural life allowed these towns to remain more vertical compared to civitates. The street-level urban structure varies depending on
904-489: A hollow-post mill, the post on which the body is mounted is hollowed out, to accommodate the drive shaft. This makes it possible to drive machinery below or outside the body while still being able to rotate the body into the wind. Hollow-post mills driving scoop wheels were used in the Netherlands to drain wetlands since the early 15th century onwards. By the end of the 13th century, the masonry tower mill, on which only

" The reason why many wings end up in landfill is that they are incredibly difficult to separate from each other, which you will have to do if you hope to be able to recycle the fiberglass ", says Lykke Margot Ricard, Associate Professor in Innovation and Technological Foresight and education leader for civil engineering in Product Development and Innovation at
1130-539: A landfill at Gerringe in the middle of Lolland in 2020. In the United States , worn-out wind turbine blades made of fiberglass go to the handful of landfills that accept them (e.g., in Lake Mills , Iowa; Sioux Falls , South Dakota; Casper ). Windpumps were used to pump water since at least the 9th century in what is now Afghanistan , Iran , and Pakistan . The use of windpumps became widespread across
1243-455: A local shopfront such as a bakery or alehouse, while others were casual traders who set up a stall or carried their wares around in baskets on market days. Market trade supplied for the needs of local consumers whether they were visitors or local residents. Braudel and Reynold have made a systematic study of European market towns between the 13th and 15th century. Their investigation shows that in regional districts markets were held once or twice

Import and export was to be conducted only through market towns, to allow oversight of commerce and to simplify the imposition of excise taxes and customs duties . This practice served to encourage growth in areas which had strategic significance, providing a local economic base for the construction of fortifications and sufficient population to defend
1469-473: A number of market towns in Saxony throughout the 11th century and did much to develop peaceful markets by granting a special 'peace' to merchants and a special and permanent 'peace' to market-places. With the rise of the territories, the ability to designate market towns was passed to the princes and dukes, as the basis of German town law . The local ordinance status of a market town ( Marktgemeinde or Markt )
1582-604: A place where the right to hold a regular market or fair was granted by a ruling authority (either royal, noble, or ecclesiastical). As in the rest of the UK, the area in which the cross was situated was almost always central: either in a square; or in a broad, main street. Towns which still have regular markets include: Inverurie , St Andrews , Selkirk , Wigtown , Kelso , and Cupar . Not all still possess their mercat cross (market cross). Dutch painters of Antwerp took great interest in market places and market towns as subject matter from
1695-412: A relationship with customers and may have offered added value services, such as credit terms to reliable customers. The economy was characterised by local trading in which goods were traded across relatively short distances. Braudel reports that, in 1600, grain moved just 5–10 miles (8.0–16.1 km); cattle 40–70 miles (64–113 km); wool and woollen cloth 20–40 miles (32–64 km). However, following

The Irish Mail train from Euston to Holyhead ran into them. Its leading coaches were enveloped in flame which burned occupants alive. In all 33 people died. An inquest was held a few days after and ran until early September of
1921-428: A small seaport or a market town prior to export. This encouraged local merchants to ensure trading went through them, which was so effective in limiting unsupervised sales ( smuggling ) that customs revenues increased from less than 30% of the total tax revenues in 1600 to more than 50% of the total taxes by 1700. Norwegian "market towns" died out and were replaced by free markets during the 19th century. After 1952, both

The miller can adjust the amount of cloth spread according to the wind and the power needed. In medieval mills, the sailcloth was wound in and out of a ladder-type arrangement of sails. Later mill sails had a lattice framework over which
2147-455: A successful market town attracted people, generated revenue and would pay for the town's defences. In around the 12th century, European kings began granting charters to villages allowing them to hold markets on specific days. Framlingham in Suffolk is a notable example of a market situated near a fortified building. Additionally, markets were located where transport was easiest, such as at

The first wind turbines were built by the end of the nineteenth century by James Blyth in Scotland (1887), Charles F. Brush in Cleveland, Ohio (1887–1888) and Poul la Cour in Denmark (1890s). La Cour's mill from 1896 later became the local power of
3051-478: Is an example of this. A number of studies have pointed to the prevalence of the periodic market in medieval towns and rural areas due to the localised nature of the economy. The marketplace was the commonly accepted location for trade, social interaction, transfer of information and gossip. A broad range of retailers congregated in market towns – peddlers, retailers, hucksters, stallholders, merchants and other types of trader. Some were professional traders who occupied

The early tower mills did not survive the gales of the Cape Peninsula , so in 1717 the Heeren XVII sent carpenters, masons, and materials to construct a durable mill. The mill, completed in 1718, became known as the Oude Molen and was located between Pinelands Station and the Black River. Long since demolished, its name lives on as that of a Technical school in Pinelands . By 1863, Cape Town had 11 mills stretching from Paarden Eiland to Mowbray . A wind turbine

As the 21st century began, rising concerns over energy security , global warming , and eventual fossil fuel depletion led to an expansion of interest in all available forms of renewable energy . Worldwide, many thousands of wind turbines are now operating, with a total nameplate capacity of 591 GW as of 2018. In an attempt to make wind turbines more efficient and increase their energy output, they are being built bigger, with taller towers and longer blades, and being increasingly deployed in offshore locations. While such changes increase their power output, they subject

Norway included a subordinate category to the market town, the "small seaport" ( Norwegian lossested or ladested ), which was a port or harbor with a monopoly to import and export goods and materials in both the port and a surrounding outlying district. Typically, these were locations for exporting timber, and importing grain and goods. Local farm goods and timber sales were all required to pass through merchants at either

Flapwise loading, one of the two different types of loading that blades are subject to, is caused by the wind pressure, and edgewise loading (the second type of loading) is caused by the gravitational force and torque load. The former loading subjects the spar laminate on the pressure (upwind) side of the blade to cyclic tension-tension loading, while

The spread of tower mills came with a growing economy that called for larger and more stable sources of power, though they were more expensive to build. In contrast to the post mill, only the cap of the tower mill needs to be turned into the wind, so the main structure can be made much taller, allowing the sails to be made longer, which enables them to provide useful work even in low winds. The cap can be turned into

Multiple-sailed mills, with five, six, or eight sails, were built in Great Britain (especially in and around the counties of Lincolnshire and Yorkshire ), Germany, and less commonly elsewhere. Earlier multiple-sailed mills are found in Spain, Portugal, Greece, parts of Romania, Bulgaria, and Russia. A mill with an even number of sails has

The Zaan district has been said to have been the first industrialized region of the world with around 600 operating wind-powered industries by the end of the eighteenth century. Economic fluctuations and the industrial revolution had a much greater impact on these industries than on grain and drainage mills, so only very few are left. Construction of mills spread to

By the 13th century, however, a movement against Sunday markets gathered momentum, and the market gradually moved to a site in town's centre and was held on a weekday. By the 15th century, towns were legally prohibited from holding markets in church-yards. Archaeological evidence suggests that Colchester is England's oldest recorded market town, dating to at least

Regarded as an icon of Dutch culture , there are approximately 1,000 windmills in the Netherlands today. Wind-powered machines may have been known earlier, but there is no clear evidence of windmills before the 9th century. Hero of Alexandria (Heron) in first-century Roman Egypt described what appears to be
8249-787: The horizontal windmill from Persia-Middle East to Southern Europe in the preceding century. The earliest certain reference to a windmill in Northern Europe (assumed to have been of the vertical type) dates from 1185, in the former village of Weedley in Yorkshire which was located at the southern tip of the Wold overlooking the Humber Estuary . Several earlier, but less certainly dated, 12th-century European sources referring to windmills have also been found. These earliest mills were used to grind cereals . The evidence at present
8362-413: The lack of town walls. Most market towns were chartered in the 14th and 15th centuries and typically developed around 13th-century villages that had preceded them. A boom in the raising of livestock may have been a trigger for the upsurge in the number of market towns during that period. Archaeological studies suggest that the ground plans of such market towns had multiple streets and could also emerge from
8475-521: The late 19th century, steel blades and towers replaced wooden construction. At their peak in 1930, an estimated 600,000 units were in use. Firms such as U.S. Wind Engine and Pump Company, Challenge Wind Mill and Feed Mill Company, Appleton Manufacturing Company, Star, Eclipse , Fairbanks-Morse , Dempster Mill Manufacturing Company , and Aermotor became the main suppliers in North and South America. These windpumps are used extensively on farms and ranches in
8588-404: The legal basis for defining a "town". For instance, Newport, Shropshire , is in the borough of Telford and Wrekin but is separate from Telford . In England, towns with such rights are usually distinguished with the additional status of borough . It is generally accepted that, in these cases, when a town was granted a market, it gained the additional autonomy conferred to separate towns. Many of
8701-519: The local town council . Failing that, the Crown can grant a licence. As the number of charters granted increased, competition between market towns also increased. In response to competitive pressures, towns invested in a reputation for quality produce, efficient market regulation and good amenities for visitors such as covered accommodation. By the thirteenth century, counties with important textile industries were investing in purpose built market halls for
8814-464: The market. If the travel time exceeded this standard, a new market town could be established in that locale. As a result of the limit, official market towns often petitioned the monarch to close down illegal markets in other towns. These distances are still law in England today. Other markets can be held, provided they are licensed by the holder of the Royal Charter, which tends currently to be
8927-455: The markets were open-air, held in what is usually called (regardless of its actual shape) the market square or market place , sometimes centred on a market cross ( mercat cross in Scotland). They were and are typically open one or two days a week. In the modern era, the rise of permanent retail establishments reduced the need for periodic markets. The primary purpose of a market town is
9040-417: The medieval period, but to have been independent inventions by 18th-century engineers. The horizontal-axis or vertical windmill (so called due to the plane of the movement of its sails) is a development of the 12th century, first used in northwestern Europe, in the triangle of northern France , eastern England and Flanders . It is unclear whether the vertical windmill was influenced by the introduction of
9153-456: The milling machinery. The first post mills were of the sunken type, where the post was buried in an earth mound to support it. Later, a wooden support was developed called the trestle . This was often covered over or surrounded by a roundhouse to protect the trestle from the weather and to provide storage space. This type of windmill was the most common in Europe until the 19th century when more powerful tower and smock mills replaced them. In
9266-502: The monastery's abbot. Edward I is known to have briefly stayed there in December 1294 during his invasion of Wales to suppress the revolt of Madog ap Llywelyn . Sites of historical interest include two Iron Age hillforts ; Castell Cawr at Tan y Gopa and Dinorben (now virtually disappeared owing to limestone quarrying ) at St. George. On Gallt y Felin Wynt, a hill above the town known as Bryn Tŵr or by its English name 'Tower Hill',
9379-657: The much greater figure of merit of CFRP. When the Vindeby Offshore Wind Farm was taken down in Denmark in 2017, 99% of the not- degradable fiberglass from 33 wind turbine blades ended as cut up at the Rærup Controlled Landfill near Aalborg and in 2020, with considerably larger fiberglass quantities, even though it is the least environmentally friendly way of handling waste . Scrapped wind turbine blades are set to become
9492-438: The nineteenth century. More recently, windmills have been preserved for their historic value, in some cases as static exhibits when the antique machinery is too fragile to be put in motion, and other cases as fully working mills. Of the 10,000 windmills in use in the Netherlands around 1850, about 1,000 are still standing. Most of these are being run by volunteers, though some grist mills are still operating commercially. Many of
9605-491: The provision of goods and services to the surrounding locality. Although market towns were known in antiquity, their number increased rapidly from the 12th century. Market towns across Europe flourished with an improved economy, a more urbanised society and the widespread introduction of a cash-based economy. Domesday Book of 1086 lists 50 markets in England. Some 2,000 new markets were established between 1200 and 1349. The burgeoning of market towns occurred across Europe around
9718-513: The purchasing habits of the monks and other individuals in medieval England, suggests that consumers of the period were relatively discerning. Purchase decisions were based on purchase criteria such as consumers' perceptions of the range, quality, and price of goods. This informed decisions about where to make their purchases. As traditional market towns developed, they featured a wide main street or central market square . These provided room for people to set up stalls and booths on market days. Often
9831-434: The rest of town, with 69.3% of people having no Welsh identity in the 2011 census. "I have observed, at low-water, far from the clayey banks, a long tract of hard loam, filled with the bodies of oak trees, tolerably entire; but so soft as to be cut with a knife as easily as wax. The wood is collected by the poorer people, and after being brought to dry upon the beach, is carried home and used as fuel; but, in burning, it emits
9944-487: The rise of a merchant class led to the import and exports of a broad range of goods, contributing to a reduced reliance on local produce. At the centre of this new global mercantile trade was Antwerp , which by the mid-16th century, was the largest market town in Europe. A good number of local histories of individual market towns can be found. However, more general histories of the rise of market-towns across Europe are much more difficult to locate. Clark points out that while
10057-513: The sailcloth was spread, while in colder climates, the cloth was replaced by wooden slats, which were easier to handle in freezing conditions. The jib sail is commonly found in Mediterranean countries and consists of a simple triangle of cloth wound round a spar. In all cases, the mill needs to be stopped to adjust the sails. Inventions in Great Britain in the late eighteenth and nineteenth centuries led to sails that automatically adjust to
10170-433: The sale of cloth. Specific market towns cultivated a reputation for high quality local goods. For example, London's Blackwell Hall became a centre for cloth, Bristol became associated with a particular type of cloth known as Bristol red , Stroud was known for producing fine woollen cloth, the town of Worsted became synonymous with a type of yarn; Banbury and Essex were strongly associated with cheeses. A study on
10283-574: The same time. Initially, market towns most often grew up close to fortified places, such as castles or monasteries, not only to enjoy their protection, but also because large manorial households and monasteries generated demand for goods and services. Historians term these early market towns "prescriptive market towns" in that they may not have enjoyed any official sanction such as a charter, but were accorded market town status through custom and practice if they had been in existence prior to 1199. From an early stage, kings and administrators understood that
10396-695: The same year. It concluded that it was no accident and that the two brakesmen of the goods train to which the petroleum wagons had previously been attached were to blame, and the deaths were manslaughter. Abergele Sanitorium was built just outside Abergele in 1910; it became a community hospital in the 1980s. On 30 June 1969, the evening before the Investiture of the Prince of Wales in Caernarfon , two members of Mudiad Amddiffyn Cymru (Welsh Defence Movement), Alwyn Jones and George Taylor, were killed when
10509-574: The sample testing of markets by Edward I the "lawgiver" , who summoned the Model Parliament in 1295 to perambulate the boundaries of forest and town. Market towns grew up at centres of local activity and were an important feature of rural life and also became important centres of social life, as some place names suggest: Market Drayton , Market Harborough , Market Rasen , Market Deeping , Market Weighton , Chipping Norton , Chipping Ongar , and Chipping Sodbury – chipping
10622-446: The saws. Windmills have been used to power many other industrial processes, including papermills , threshing mills, and to process oil seeds, wool, paints, and stone products. In the 14th century, windmills became popular in Europe; the total number of wind-powered mills is estimated to have been around 200,000 at the peak in 1850, which is close to half of the some 500,000 water wheels . Windmills were applied in regions where there
10735-520: The sea is little more than half a mile away at this point, this suggests that the sea has made some considerable advance over the centuries. Outside the church is a penitential stone where sinners had to do penance by standing, dressed in white, by the stone and beseech the congregation for mercy as they entered and left the church. In 1868 the railway line through Abergele was the site of the worst railway disaster in Britain to that time. The result of
10848-538: The stiffness, strength, and toughness requirements determined by the loading, the blade needs to be lightweight, and the weight of the blade scales with the cube of its radius. To determine which materials fit the criteria described above, a parameter known as the beam merit index is defined: Mb = E^1/2 / rho, where E is Young's modulus and rho is the density. The best blade materials are carbon fiber and glass fiber reinforced polymers ( CFRP and GFRP ). Currently, GFRP materials are chosen for their lower cost, despite
10961-415: The stone nuts directly, instead of the spur gear arrangement. Additional gear wheels drive a sack hoist or other machinery. The machinery differs if the windmill is used for other applications than milling grain. A drainage mill uses another set of gear wheels on the bottom end of the upright shaft to drive a scoop wheel or Archimedes' screw . Sawmills uses a crankshaft to provide a reciprocating motion to
11074-428: The suction (downwind) side of the blade is subject to cyclic compression-compression loading. Edgewise bending subjects the leading edge to a tensile load, and the trailing edge to a compressive load. The remainder of the shell, not supported by the spars or laminated at the leading and trailing edges, is designed as a sandwiched structure, consisting of multiple layers to prevent elastic buckling. In addition to meeting
11187-466: The time of the Roman occupation of Britain's southern regions. Another ancient market town is Cirencester , which held a market in late Roman Britain. The term derived from markets and fairs first established in 13th century after the passage of Magna Carta , and the first laws towards a parlement . The Provisions of Oxford of 1258 were only possible because of the foundation of a town and university at
11300-428: The town and in the surrounding district. Norway developed market towns at a much later period than other parts of Europe. The reasons for this late development are complex but include the sparse population, lack of urbanisation, no real manufacturing industries and no cash economy. The first market town was created in 11th century Norway, to encourage businesses to concentrate around specific towns. King Olaf established
11413-747: The town erected a market cross in the centre of the town, to obtain God's blessing on the trade. Notable examples of market crosses in England are the Chichester Cross , Malmesbury Market Cross and Devizes, Wiltshire. Market towns often featured a market hall , as well, with administrative or civic quarters on the upper floor, above a covered trading area. Market towns with smaller status include Minchinhampton , Nailsworth , and Painswick near Stroud, Gloucestershire . A "market town" may or may not have rights concerning self-government that are usually
11526-408: The town some protection from rival markets. When a chartered market was granted for specific market days, a nearby rival market could not open on the same days. Across the boroughs of England, a network of chartered markets sprang up between the 12th and 16th centuries, giving consumers reasonable choice in the markets they preferred to patronise. Until about 1200, markets were often held on Sundays,
11639-551: The village of Askov. By 1908, there were 72 wind-driven electric generators in Denmark, ranging from 5 to 25 kW. By the 1930s, windmills were widely used to generate electricity on farms in the United States where distribution systems had not yet been installed, built by companies such as Jacobs Wind , Wincharger, Miller Airlite, Universal Aeroelectric, Paris-Dunn, Airline, and Winpower. The Dunlite Corporation produced turbines for similar locations in Australia. Forerunners of modern horizontal-axis utility-scale wind generators were
11752-489: The wind either by winches or gearing inside the cap or from a winch on the tail pole outside the mill. A method of keeping the cap and sails into the wind automatically is by using a fantail , a small windmill mounted at right angles to the sails, at the rear of the windmill. These are also fitted to tail poles of post mills and are common in Great Britain and English-speaking countries of the former British Empire, Denmark, and Germany but rare in other places. Around some parts of
11865-450: The wind speed without the need for the miller to intervene, culminating in patent sails invented by William Cubitt in 1807. In these sails, the cloth is replaced by a mechanism of connected shutters. In France, Pierre-Théophile Berton invented a system consisting of longitudinal wooden slats connected by a mechanism that lets the miller open them while the mill is turning. In the twentieth century, increased knowledge of aerodynamics from
11978-461: The windmill is closed or not functional. A slight tilt of the sails (top blade at 1 o'clock) signals joy, such as the birth of a healthy baby. A tilt of the blades to 11-2-5-8 o'clock signals mourning, or warning. It was used to signal the local region during Nazi operations in World War II, such as searches for Jews. Across the Netherlands, windmills were placed in mourning positions in honor of
12091-521: The wing scrap have been disposed of in Denmark, and the waste problem will grow significantly in the coming years when more and more wind turbines have reached their end of life. According to the SDU lecturer's calculations, the waste sector in Denmark will have to receive 46,400 tonnes of fiberglass from wind turbine blades over the next 20–25 years. As so, at the island , Lolland , in Denmark, 250 tonnes of fiberglass from wind turbine waste also pours up on
12204-482: Was derived from a Saxon verb meaning "to buy". A major study carried out by the University of London found evidence for least 2,400 markets in English towns by 1516. The English system of charters established that a new market town could not be created within a certain travelling distance of an existing one. This limit was usually a day's worth of travelling (approximately 10 kilometres (6.2 mi)) to and from
12317-537: Was filmed there in 1996, starring Edward Fox and Katherine Heigl . In a Welsh antiquarian book from 1860, it mentions that there has always been a 'local tradition or popular opinion that the original Abergele was overwhelmed by the sea' and that an inscribed stone at St Michael's parish church (built on the site of the old clas) which was once readable but had been weathered over time read; "Yma mae'n gorwedd, Yn mynwent Mihangel, Gwr oedd ei annedd, Dair milltir yn y gogledd" Although through oral tradition,
12430-418: Was first built to pump water and subsequently modified to grind grain as well. The first practical windmills were panemone windmills , using sails that rotated in a horizontal plane, around a vertical axis. Made of six to 12 sails covered in reed matting or cloth material, these windmills were used to grind grain or draw up water. A medieval account reports that windmill technology was used in Persia and
12543-511: Was too little water, where rivers freeze in winter and in flat lands where the flow of the river was too slow to provide the required power. With the coming of the Industrial Revolution , the importance of wind and water as primary industrial energy sources declined, and they were eventually replaced by steam (in steam mills ) and internal combustion engines, although windmills continued to be built in large numbers until late in
12656-405: Was under Danish rule, Danish merchants held a monopoly on trade with Iceland until 1786. With the abolishment of the trading monopoly, six market town ( Icelandic kaupstaður ) were founded around the country. All of them, except for Reykjavík , would lose their market rights in 1836. New market towns would be designated by acts from Alþingi in the 19th and 20th century. In the latter half of
12769-401: Was used mostly for lifting water from wells. Larger versions were also used for tasks such as sawing wood, chopping hay, and shelling and grinding grain. In early California and some other states, the windmill was part of a self-contained domestic water system which included a hand-dug well and a wooden water tower supporting a redwood tank enclosed by wooden siding known as a tankhouse .
