Henrik Stiesdal
Henrik Stiesdal (born April 14, 1957) is a Danish inventor and businessman in the modern wind power industry. In 1978, he designed one of the first wind turbines representing the so-called "Danish Concept" which dominated the global wind industry through the 1980s. Until 2014, Stiesdal was the Chief Technology Officer of Siemens Wind Power. During his professional career, Stiesdal has made more than 175 inventions and has received more than 650 patents related to wind power technology. Early life Henrik Stiesdal was born in Hørsholm, a town located in the East of Denmark. Between 1979–1988 he studied medicine, physics and biology at the University of Southern Denmark in Odense. In 1976, Stiesdal became motivated by the steam plume from a powerplant cooling tower in England to build two small test turbines out of wood, steel and fabric.Rosendal, Sara.Vindmøllepioner: Den første blev rejst på ladet af en traktorvogn [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hørsholm
Hørsholm () is an urban area on the Øresund coast approximately north of Copenhagen, Denmark. It covers most of Hørsholm Municipality and straddles the borders neighbouring Fredensborg Municipality and Rudersdal Municipality. Hørsholm proper is developed around Hirschholm Palace, which was constructed in the 1730s, but the town has later absorbed several of the nearby communities that are of much older origins. History Palace and market town Hørsholm was founded in connection with the construction of Hirschholm Palace. Niels Eigtved created a plan for a residence town in 1737 and to stimulate its growth, it was given status as market town in 1739. However, it never came to serve as a market town and was still only a small settlement when the palace was demolished between 1810 and 1816. Over the following decades it grew as a garrison town and a local centre for trade. Industrialization A textile factory, later known as the Royal Military Textile Factory, had already bee ...

Variable Speed Wind Turbine
A variable speed wind turbine is one which is specifically designed to operate over a wide range of rotor speeds. It is in direct contrast to fixed speed wind turbine where the rotor speed is approximately constant. The reason to vary the rotor speed is to capture the maximum aerodynamic power in the wind, as the wind speed varies. The aerodynamic efficiency, or coefficient of power, C_p for a fixed blade pitch angle is obtained by operating the wind turbine at the optimal tip-speed ratio as shown in the following graph. Tip-speed ratio is given by the following expression, \lambda = \frac where \omega is the rotor speed (in radians per second), R is the radius of the rotor, and v is the wind speed. As the wind speed varies, the rotor speed must be varied to maintain peak efficiency. Background Before the need to connect wind turbines to the grid, turbines were fixed-speed. This was not a problem because turbines did not have to be synchronized with the frequency of the g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Hørsholm Municipality
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

Poul La Cour
Poul la Cour (13 April 1846 – 24 April 1908) was a Danish scientist, inventor and educationalist. Today la Cour is especially recognized for his early work on wind power, both experimental work on aerodynamics and practical implementation of wind power plants. He worked most of his life at Askov Folk High School where he developed the historic genetic method of teaching the sciences. Early in his life he was a telegraphic inventor working with multiplex telegraphy. Biography Poul la Cour was born on 13 April 1846 on a farm near Ebeltoft in Denmark. His father was a modern farmer introducing new technology at his farm as the first among neighbours. However la Cour had his gifts in mathematics from his mother. At Latin school in Randers he performed very poorly in languages and had to give up an early wish to become a priest. His brother Jørgen la Cour (1838–98), who knew the possible directions of study in Copenhagen, soon directed his brother into the new field of meteorol ...

Floating Wind Turbine
A floating wind turbine is an offshore wind turbine mounted on a floating structure that allows the turbine to generate electricity in water depths where fixed-foundation turbines are not feasible. Floating wind farms have the potential to significantly increase the sea area available for offshore wind farms, especially in countries with limited shallow waters, such as Japan, France and US West coast. Locating wind farms further offshore can also reduce visual pollution, provide better accommodation for fishing and shipping lanes, and reach stronger and more consistent winds. Commercial floating wind turbines are mostly at the early phase of development, with several single turbine prototypes having been installed since 2007. , there are 3 operational floating wind farms. The first is the 30 MW Hywind Scotland with 5 floating turbines, developed by Equinor ASA and commissioned in October 2017. History The concept for large-scale offshore floating wind turbines was introduce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrolysis
The pyrolysis (or devolatilization) process is the thermal decomposition of materials at elevated temperatures, often in an inert atmosphere. It involves a change of chemical composition. The word is coined from the Greek-derived elements ''pyro'' "fire", "heat", "fever" and '' lysis'' "separating". Pyrolysis is most commonly used in the treatment of organic materials. It is one of the processes involved in charring wood.''Burning of wood'' , InnoFireWood's website. Accessed on 2010-02-06. In general, pyrolysis of organic substances produces volatile products and leaves , a carbon-rich solid residue. Extreme pyrolysis, which leaves mostly |
