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 wa ...

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.

Wind Farm
A wind farm or wind park, also called a wind power station or wind power plant, is a group of wind turbines in the same location used to produce electricity. Wind farms vary in size from a small number of turbines to several hundred wind turbines covering an extensive area. Wind farms can be either onshore or offshore. Many of the largest operational onshore wind farms are located in China, India, and the United States. For example, the largest wind farm in the world, Gansu Wind Farm in China had a capacity of over 6,000 MW by 2012,Watts, Jonathan & Huang, CecilyWinds Of Change Blow Through China As Spending On Renewable Energy Soars ''The Guardian'', 19 March 2012, revised on 20 March 2012.

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 vario ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smock Mill
The smock mill is a type of windmill that consists of a sloping, horizontally weatherboarded, thatched, or shingled tower, usually with six or eight sides. It is topped with a roof or cap that rotates to bring the sails into the wind. This type of windmill got its name from its resemblance to smocks worn by farmers in an earlier period. Construction Smock mills differ from tower mills, which are usually cylindrical rather than hexagonal or octagonal, and built from brick or stone masonry instead of timber. The majority of smock mills are octagonal in plan, with a lesser number hexagonal in plan, such as Killick's Mill, Meopham. A very small number of smock mills were decagonal or dodecagonal in plan, an example of the latter being at Wicken, Cambridgeshire. Distribution Smock mills exist in Europe and particularly in England, where they were common, particularly in the county of Kent, where the tallest surviving smock mill in the United Kingdom, Union Mill, can be found at ...

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 ...
