De Nijlânnermolen, Workum
De Nijlânnermolen is a smock mill in Workum, Friesland, Netherlands. It has been restored to working order and is designated as a reserve mill. It is listed as a Rijksmonument. History ''De Nijlânnermolen'' was built in 1785. The first mill on this site was built in 1770. It had a sail span of 60 Dutch feet (). The mill drove a scoopwheel. It soon became apparent that this mill was too small due to insufficient pumping capacity. Following a major inundation in 1776, a new mill was built by millwright Widmer Sipkes in 1784-85. The mill had originally been built in 1770 and was moved here, being erected on the base of the existing mill. It had a sail span of 76 Dutch feet (). ''De Nijlânnermolen'' was worked by wind until 1950, when a diesel engine was placed in ''De Nijlânnermolen'' and a new, larger, Archimedes' screw was installed. The mill was sold to the Waterschap Tusken Mar en Klif. In 1987, the mill was sold to the Workumer Molenstichting for ƒ1. The mill was restor ...

Windpump
A windpump is a type of windmill 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 h ...

Dutch Guilder
The guilder ( nl, gulden, ) or florin was the currency of the Netherlands from the 15th century until 2002, when it was replaced by the euro. The Dutch name ''gulden'' was a Middle Dutch adjective meaning "golden", and reflects the fact that, when first introduced in 1434, its value was about equal to (i.e., it was on par with) the Italian gold florin. The Dutch guilder was a ''de facto'' reserve currency in Europe in the 17th and 18th centuries. Between 1999 and 2002, the guilder was officially a "national subunit" of the euro. However, physical payments could only be made in guilders, as no euro coins or banknotes were available. The exact exchange rate, still relevant for old contracts and for exchange of the old currency for euros at the central bank, is 2.20371 Dutch guilders for 1 euro. Inverted, this gives 0.453780 euros for 1 guilder. Derived from the Dutch guilder are the Netherlands Antillean guilder (still in use in Curaçao and Sint Maarten) and the Surinamese gui ...

Agricultural Buildings In The Netherlands
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals ( grains), vegetables, fruits, cooking oils, meat, mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Windmills Completed In 1785
A windmill is a structure that converts wind power into rotational energy using vanes called sails or blades, specifically to mill grain (gristmills), but the term is also extended to windpumps, wind turbines, and other applications, in some parts of the English speaking world. The term wind engine is sometimes used to describe such devices. Windmills were used throughout the 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 Dutch culture, there are approximately 1,000 windmills in the Netherlands today. Forerunners 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 a wind-driven wheel to power a machine.Dietrich Lohrmann, "Von der östlichen z ...

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Thatch
Thatching is the craft of building a roof with dry vegetation such as straw, water reed, sedge (''Cladium mariscus''), rushes, heather, or palm branches, layering the vegetation so as to shed water away from the inner roof. Since the bulk of the vegetation stays dry and is densely packed—trapping air—thatching also functions as insulation. It is a very old roofing method and has been used in both tropical and temperate climates. Thatch is still employed by builders in developing countries, usually with low-cost local vegetation. By contrast, in some developed countries it is the choice of some affluent people who desire a rustic look for their home, would like a more ecologically friendly roof, or who have purchased an originally thatched abode. History Thatching methods have traditionally been passed down from generation to generation, and numerous descriptions of the materials and methods used in Europe over the past three centuries survive in archives and early public ...

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
