Terpzigt, Marssum
Terpzigt is a drainage mill in Marssum, Friesland, Netherlands. It is the smallest ''spinnenkop'', a type of hollow post windmill. The mill is listed as a Rijksmonument, number 8625. History The windmill was built in 1888. Before the merger of several waterboards it drained the polder Tolsma. It was restored to working order in 1981 by millwright Dijkstra from Giekerk though it can no longer drain water from the polder, instead it pumps water round in a circuit. In 2011 the windshaft and stocks were replaced. Description ''Terpzigt'' is what the Dutch describe as a "spinnenkop" (English: spiderhead mill). It is a small hollow post mill winded by a winch. The four common sails have a span of and are carried on a wooden ''windshaft''. The ''brake wheel'' on the windshaft drives the ''wallower'' at the top of the ''upright shaft'', which passed through the main post. At the bottom of the ''upright shaft'', the ''crown wheel'' drives the Archimedes' screw The Archimedes scr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windmill Sail
Windmills are powered by their sails. Sails are found in different designs, 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 variou ... [...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 hydraulic machines. Using Archimedes screws as water pumps (Archimedes screw pump (ASP) or screw pump) dates back many centuries. As a machine used for pump, transferring water from a low-lying body of water into irrigation ditches, water is pumped 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. Screw turbine, Archimedes Screws Turbines (ASTs) are a new form of small hydroelectric powerplant that can be applied even in low head sites. Screw turbine, Archimedes screw 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 rates that is not ideal for traditional turbines and not occupied by high performance technologies. The Archimedes screw is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polder
A polder () is a low-lying tract of land that forms an artificial hydrological entity, enclosed by embankments known as dikes. The three types of polder are: # Land reclaimed from a body of water, such as a lake or the seabed # Flood plains separated from the sea or river by a dike # Marshes separated from the surrounding water by a dike and subsequently drained; these are also known as ''koogs'', especially in Germany The ground level in drained marshes subsides over time. All polders will eventually be below the surrounding water level some or all of the time. Water enters the low-lying polder through infiltration and water pressure of groundwater, or rainfall, or transport of water by rivers and canals. This usually means that the polder has an excess of water, which is pumped out or drained by opening sluices at low tide. Care must be taken not to set the internal water level too low. Polder land made up of peat (former marshland) will sink in relation to its previous l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trestle (mill)
The trestle of a post mill is the arrangement of the ''main post'', ''crosstrees'' and ''quarterbars'' that form the substructure of this type of windmill. It may or may not be surrounded by a '' roundhouse''. Post mills without a roundhouse are known as ''open trestle post mills''. A trestle mill is a variety of smock mill, usually without weatherboards, formerly used for drainage in the Norfolk Broads. Examples can be found at Horning, Ludham and St Olaves St Olaves is a village in the English county of Norfolk. The village is situated on the River Waveney, south-west of the town of Great Yarmouth and the same distance north-west of the Suffolk town of Lowestoft. It is within The Broads nation .... A well preserved example of a timber crosstree, from the trestle of a medieval windmill, was excavated by archaeologists at Humberstone, near Leicester, in 2007.

Windmills In Friesland
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 ...
