Tjasker
The tjasker (West Frisian: , German: ) is a small type of windmill used solely for drainage purposes. It is distinctive for its simple construction, featuring only a single inclined shaft that carries the sails on one end and an Archimedes' screw on the other, in this way avoiding the need for any gearing. The tjasker is commonly known as a typical Frisian windmill though it is also found in other Dutch provinces and in north Germany. History The tjasker seems to have been developed somewhere towards the end of the 16th century, though there is no conclusive date for its invention. The total number of tjaskers at their peak is also unclear. The mills were used to drain small plots of land but also found their use at peat digging sites as they could be easily moved. Millwright R.W. Dijksma of Giethoorn was well known for his tjasker building. He constructed 400 to 500 tjaskers between 1910 and 1945, though these numbers include hand powered Archimedes' screws.

Tjaskers In The Netherlands
A Tjasker ( nl, tjasker) is a type of small drainage windmill used in the Netherlands and Germany. There are 28 tjaskers remaining the Netherlands. Locations Drenthe, Friesland, Overijssel Most tjaskers are located in the three northern provinces, see: * tjaskers in Friesland * tjaskers in Overijssel * tjaskers in Drenthe The remainder is described below. Amsterdam (North Holland) The paaltjasker was built in 1978 for the Floriade (flower show) of 1982 and was left behind after its end. It was restored in 2003 after being derelict for some years, though it is not really functional because of its sheltered position. The tjasker has four Common sails. It is located in the public park surrounding the Gaasperplas lake and can be reached on foot. Arnhem (Gelderland) The boktjasker was built around 1875 near Wâlterswâld. It was donated to the Netherlands Open Air Museum and re-erected there in 1928 as a static object. It was moved to a different site in the museum ground ...

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 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 his innovation in 15 ...

Tjaskers In Germany
A Fluttermühle ( nl, tjasker) is a type of small drainage windmill used in the Netherlands and Germany. There are six fluttermühle remaining in Germany, all in Lower Saxony. Locations Bedekaspel The boktjasker of Bedekaspel is located near the drainage smock mill Agnes. The system of ditches do not form a complete circle so the mill can only operate with southerly to westerly winds. In 2011 the mill was in a state of disrepair. Grotegaste/Lütjegaste The paaltjasker is located west of Ihrhove near the hamlet Grotegaste and was built in 2000 by millwright Richard Kluin from Ihrhove, together with the fluttermühle of Weenermoor (see below). The mill has four Common sails and is fully functional. Moorsee The paaltjasker is located next to the Moorseer Mühle and is part of its museum. The mill has four Common sails. Münkeboe The boktjasker is part of the village museum Münkeboe. It is a non functional replica or model. Riepe The boktjasker was ...

Ossenzijl - Tjasker
Ossenzijl ( Dutch Low Saxon: ''Ossenziel'') is a village in the municipality Steenwijkerland of the Dutch province of Overijssel. It started as a sluice owned by the Osse family. It is an entry point to the Weerribben-Wieden National Park. History The village was first mentioned in 1437 as Ossenzyle, and refers to a sluice which was owned by the Osse family. The original sluice was destroyed in 1570, and rebuilt in 1790. Ossenzijl developed into a harbour village for peat export. In 1840, it was home to 281 people. In 1930, the sluice was removed. Several small windmills have been built on the edge of the Weerribben, including two ''tjaskers'', little windmills for drainage. Ossenzijl serves as one of the entry points to the Weerribben, a large bog, and the Frisian Lakes. After World War II, the village became a tourist destination. Many of the houses were rebuilt as a holiday homes, and a marina was added to the village. The Weerribben was declared a national park in 1992. In ...

Peat
Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of , which is the average depth of the boreal orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. ''Sphagnum'' moss, also called peat moss, is one of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giethoorn
Giethoorn () is a village in the province of Overijssel, Netherlands with a population of 2,795 in 2020. It is located in the municipality of Steenwijkerland, about 5 km southwest of Steenwijk. As a popular Dutch tourist destination both within Netherlands and abroad, Giethoorn is often referred to as "Dutch Venice" ( nl, Hollands Venetië) or the "Venice of the Netherlands". History Giethoorn used to be a pedestrian precinct, but nowadays exceptions are made. It became locally famous, especially after 1958, when the Dutch film maker Bert Haanstra made his famous comedy ''Fanfare'' there. In the old part of the village, there were no roads (though a cycling path was eventually added), and all transport was done by water over one of the many canals. The lakes in Giethoorn were formed by peat digging. Giethoorn was a separate municipality until 1973, when it became part of Brederwiede, which lost its municipality status in 2001 to merge with Steenwijk. Tourism Tourism ...

Windmill
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 östli ...

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 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. Archimedes Screws Turbines (ASTs) are a new form of small hydroelectric powerplant that can be applied even in low head sites. 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 reversible hydraulic machine, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
