Poul La Cour
Poul la Cour (13 April 1846 – 24 April 1908) was a Denmark, 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 Multiplexing, 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 th ...

This represented a great pioneer task for the company in establis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power-to-X
Power-to-X (also P2X and P2Y) are electricity conversion, energy storage, and reconversion pathways from surplus renewable energy. Power-to-X conversion technologies allow for the decoupling of power from the electricity sector for use in other sectors (such as transport or chemicals), possibly using power that has been provided by additional investments in generation. The term is widely used in Germany and may have originated there. The X in the terminology can refer to one of the following: power-to-ammonia, power-to- chemicals, power-to-fuel, power-to-gas (power-to-hydrogen, power-to-methane) power-to-liquid ( synthetic fuel), power to food, power-to-heat. Electric vehicle charging, space heating and cooling, and water heating can be shifted in time to match generation, forms of demand response that can be called power-to-mobility and power-to-heat. Collectively power-to-X schemes which use surplus power fall under the heading of flexibility measures and are particularly ...

Electrolysis
In chemistry and manufacturing, electrolysis is a technique that uses Direct current, direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of chemical element, elements from naturally occurring sources such as ores using an electrolytic cell. The voltage that is needed for electrolysis to occur is called the decomposition potential. The word "lysis" means to separate or break, so in terms, electrolysis would mean "breakdown via electricity." Etymology The word "electrolysis" was introduced by Michael Faraday in 1834, using the Greek language, Greek words "amber", which since the 17th century was associated with electrical phenomena, and ' meaning "dissolution". Nevertheless, electrolysis, as a tool to study chemical reactions and obtain pure chemical element, elements, precedes the coinage of the term and formal description by Faraday.

Askov Folk High School
Askov is a city in Pine County, Minnesota, United States. The population was 364 at the 2010 census. Minnesota State Highway 23 serves as a main route in the community, and Interstate 35 is nearby. History The village was originally within the lands of the village of Partridge, at a stop far outside the original village along Great Northern Railway; here a post office was set up, called Partridge from 1889 to 1909, before changing its name to Askov in 1909. Most of the original village of Partridge was destroyed in the 1894 Hinckley fire. The immigrants to the Danish "colony" of Askov were nationalistic Lutheran followers of the theologian and cultural leader N. F. S. Grundtvig. Danish immigrants had previously been mostly economic migrants fleeing poverty, but the first migrants to Askov were almost all Grundvigian Danes from elsewhere in the U.S. The ''Dansk Folkesamfund'' (Danish Peoples Society) was founded in 1887 by Svend Hersleb Grundtvig, N.

Paul Gottlieb Nipkow
Paul Julius Gottlieb Nipkow (; 22 August 1860 – 24 August 1940) was a German electrical engineer and inventor. He invented the Nipkow disk, which laid the foundation of television, since his disk was a fundamental component in the first televisions. Hundreds of stations experimented with television broadcasting using his disk in the 1920s and 1930s, until it was superseded by all-electronic systems in the 1940s. Nipkow has been called the "father of television", together with other early figures of television history like Karl Ferdinand Braun. The first regular television service in the world, Fernsehsender Paul Nipkow, was named in his honour. Beginnings Nipkow was born in Lauenburg (now Lębork) in the Prussian province of Pomerania, now part of Poland. While at school in neighbouring Neustadt (now Wejherowo), in the province of West Prussia, Nipkow experimented in telephony and the transmission of moving pictures. After graduation, he went to Berlin in order to study ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chronometer Watch
A chronometer (, ''khronómetron'', "time measurer") is an extraordinarily accurate mechanical timepiece, with an original focus on the needs of maritime navigation. In Switzerland, timepieces certified by the Contrôle Officiel Suisse des Chronomètres (COSC) may be marked as ''Certified Chronometer'' or ''Officially Certified Chronometer''. Outside Switzerland, equivalent bodies, such as the Japan Chronometer Inspection Institute, have in the past certified timepieces to similar standards, although use of the term has not always been strictly controlled. History The term ''chronometer'' was coined by Jeremy Thacker of Beverley, England in 1714, referring to his invention of a clock ensconced in a vacuum chamber. The term ''chronometer'' is also used to describe a marine chronometer used for celestial navigation and determination of longitude. The marine chronometer was invented by John Harrison in 1730. This was the first of a series of chronometers that enabled accurate marine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Elliott Cresson Medal
The Elliott Cresson Medal, also known as the Elliott Cresson Gold Medal, was the highest award given by the Franklin Institute. The award was established by Elliott Cresson, life member of the Franklin Institute, with $1,000 granted in 1848. The endowed award was to be "for a discovery in the Arts and Sciences, or for the invention or improvement of some useful machine, or for a new process or combination of materials in manufactures, or for ingenuity skill or perfection in workmanship." The medal was first awarded in 1875, 21 years after Cresson's death. The Franklin Institute continued awarding the medal on an occasional basis until 1998 when they reorganized their endowed awards under one umbrella, The Benjamin Franklin Awards.
