Roekmolen, Goëngahuizen
Roekmole is a hollow post mill in nature reserve ''It Eilân'' in Goëngahuizen, Friesland, Netherlands. It was moved there from polder ''Krieke'' near Aldeboarn and has been restored to working order. The mill is listed as a Rijksmonument, number 35972. (Click on "Technische gegevens" to view.) History The earliest record of a mill on the previous site was on a map published by W Eekhorn in 1849. The current mill was built in 1896 and drained polder ''Krieke''. The mill is recorded as having been restored in 1960 and again in 1976, however it spent most of the 1980s and 1990s without sails. In 2009 it was moved to its current location and restoration to working order was finished in 2011. The previous nameless mill was renamed Roekmolen. Description The ''Roekmolen'' is what the Dutch describe as a "spinnenkopmolen". It is a hollow post mill with a single storey square roundhouse. The roundhouse and body of the mill are covered with weatherboards. These are horizontal on the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Windpump
A windpump is a wind-driven device which is used for pumping water. Windpumps were used to pump water since at least the 9th century in what is now Afghanistan, Iran and Pakistan. The use of wind pumps became widespread across the Muslim world and later spread to China and Indian subcontinent, India. Windmills were later used extensively in Europe, particularly in the Netherlands and the East Anglia area of Great Britain, from the late Middle Ages onwards, to drain land for agricultural or building purposes. Simon Stevin's work in the ''waterstaet'' involved improvements to the sluices and spillways to control flooding. Windmills were already in use to pump the water out, but in ''Van de Molens'' (''On mills''), he suggested improvements, including the idea that the wheels should move slowly, and a better system for meshing of the gear teeth. These improvements increased the efficiency of the windmills used to pump water out of the polders by three times. He received a patent on ...

Post Mill
The post mill is the earliest type of European windmill. Its defining feature is that the whole body of the mill that houses the machinery is mounted on a single central vertical post. The vertical post is supported by four quarter bars. These are struts that steady the central post. The body of the windmill can be turned around the central post to bring the sails into the wind. All post mills have an arm projecting from them on the side opposite the sails and reaching down to near ground level. With some, as at :File:Saxtead Green Post Mill - geograph.org.uk - 514428.jpg, Saxtead Green, the arm carries a windmill fantail, fantail to turn the mill automatically. With the others the arm serves to rotate the mill into the wind by hand. The earliest post mills in England are thought to have been built in the 12th century. Outwood Windmill, The earliest working post mill in England still used today is to be found at Outwood, Surrey. It was built in 1665. The earliest remaining exam ...

Windmill Sail
Windmills are powered by their sails. Sails are found in different forms, from primitive common sails to the advanced patent sails. Jib sails The jib sail is found in Mediterranean countries and consists of a simple triangle of cloth wound round a spar. The mill must be stopped in order to adjust the reefing of the sail. Though rare in the UK, at least two windmills are known to have had jib sails (St Mary's, Isle of Scilly and Cann Mills, Melbury Abbas).

In medieval mills, the sailcloth was wound in and out of a ladder-type arrangement of sails. Medieval sails could be constructed with or without outer sailbars. Post-medieval mill sails have a lattice framework over which the sailcloth is spread. There are v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archimedes' Screw
The Archimedes' screw, also known as the Archimedean screw, hydrodynamic screw, water screw or Egyptian screw, is one of the earliest documented hydraulic machines. It was so-named after the Greek mathematician Archimedes who first described it around 234 BC, although the device had been developed in Egypt earlier in the century. It is a reversible hydraulic machine that can be operated both as a pump or a power generator. 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 (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 ...

Rijksmonument
A (, ) is a national heritage site of the Netherlands, listed by the agency Rijksdienst voor het Cultureel Erfgoed (RCE) acting for the Dutch Ministry of Education, Culture and Science. At the end of February 2015, the Netherlands had 61,822 listed national heritage sites, of which approximately 1,500 are listed as archaeological sites. History and criteria Until 2012, a place had to be over 50 years old to be eligible for designation. This criterion expired on 1 January 2012. The current legislation governing the monuments is the ''Monumentenwet van 1988'' ("Monument Law of 1988"). The organization responsible for caring for the monuments, which used to be called ''Monumentenzorg'', was recently renamed, and is now called Rijksdienst voor het Cultureel Erfgoed (national service for cultural heritage).

De Hollandsche Molen
Vereniging De Hollandsche Molen () ( is a Dutch organization founded in 1923 to preserve windmills in the Netherlands, to document them, and to restore them. Financial support comes from members and from grants by organizations such as the (a Dutch lottery). Their website provides access to a database which documents some 1400 mills in the Netherlands; "Het Nederlands Molenbestand" is authoritative on the topic. The organization is often given credit for organizing a powerful and effective lobby aimed at procuring money from Dutch government institutions to fund restoration projects. Its former president Frederik Stokhuyzen was one of the foremost scholars on Dutch windmills; a recently revised edition of his 1961 book ''Molens'' is still the standard book on the topic. In 1981, Prince Claus of the Netherlands became the organization's patron, and attended ten ceremonies at which windmills were reopened; at his death in 2002 the 12 windmills owned and operated by the organizat ...

Windmills In Friesland
A windmill is a machine operated by the force of wind acting on vanes or windmill sail, sails to mill (grinding), mill grain (gristmills), pump water, generate electricity, or drive other machinery. Windmills were used throughout the High Middle Ages, high medieval and early modern periods; the horizontal or panemone windmill first appeared in Persia during the 9th century, and the vertical windmill first appeared in northwestern Europe in the 12th century. Regarded as an icon of Culture of the Netherlands, Dutch culture, there are approximately 1,000 windmills in the Netherlands today. Forerunners Wind-powered machines have been known earlier, the Babylonian emperor Hammurabi had used wind mill power for his irrigation project in Mesopotamia in the 17th century BC. Later, Hero of Alexandria (Heron) in first-century Roman Egypt described what appears to be a wind-driven wheel to power a machine.Dietrich Lohrmann, "Von der östlichen zur westlichen Windmühle", ''Archiv ...
