Tinnsjø Railway Ferry
Tinnsjø railway ferry was a Norwegian railway ferry service on Lake Tinn that connected the Rjukan Line and Tinnoset Line. The long ferry trip made it possible for Norsk Hydro to transport its fertilizer from the plant at Rjukan to the port in Skien. The ferry services were operated by the company's subsidiary Norsk Transport from 1909 to 1991, when the plant closed. One of the ferries was in 1944 the target of the Norwegian heavy water sabotage when it was sunk to depth to prevent Nazi Germany from developing nuclear weapons. History Norsk Hydro was founded in 1905 by engineer and industrialist Sam Eyde as a fertilizer manufacturer. The first factory was opened at Notodden in 1907. Fertilizer factories need a lot of energy, making it beneficial to locate the plants near hydroelectric power plants. At Rjukan there was a large waterfall capable of supporting a hydroelectric plant. By 1911 Rjukan Salpeterfabrikk was opened. The Tinnsjø railway ferry service was opened in 1 ...

Rjukan
Rjukan () is a town and the administrative centre of Tinn municipality in Telemark, Norway. It is situated in Vestfjorddalen, between Møsvatn and Lake Tinn, and got its name after Rjukan Falls west of the town. The Tinn municipality council granted township status for Rjukan in 1996. The town has 3,386 inhabitants (January 2007). History Rjukan was formerly a significant industrial centre in Telemark, and the town was established between 1905 and 1916, when Norsk Hydro started saltpetre (fertilizer) production there. Rjukan was chosen because Rjukan Falls, a 104-metre waterfall, provided easy means of generating large quantities of electricity. The man with the idea to use the Rjukan falls was Sam Eyde, the founder of Hydro. It is estimated that he, together with A/S Rjukanfoss (later Norsk Hydro), used about two times the national budget of Norway to build the Rjukan power station as well as much of the surrounding town. Between 1907 and 1911, Norsk Hydro built what was at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porsgrunn
is a city and municipality in Telemark in the county of Vestfold og Telemark in Norway. It is part of the traditional region of Grenland.

Herøya
Herøya is a peninsula in the municipality of Porsgrunn, Norway.

Norsk Hydro Rjukan
Norsk Hydro Rjukan is an industrial facility operated by Norsk Hydro at Rjukan in Tinn, Norway, from 1911 to 1991. The plant manufactured chemicals related to the production of fertilizer, initially potassium nitrate from arc-produced nitric acid and later ammonia, hydrogen, and heavy water. The location was chosen for its vicinity to hydroelectric power plants built in the Måna river. 30 million tonnes of products, equivalent of 1.5 million wagon loads, were produced in Rjukan. After the closing, parts of the plants and the railway have been preserved. History Background The Telemark power-based industry adventure started in 1902 when Sam Eyde, along with Norwegian and Swedish investors, bought Rjukan Falls—establishing A/S Rjukanfos on 30 April 1903. The same year, on 13 February, Eyde and Kristian Birkeland had met and started working on refining the electric arc to produce an electric flame; allowing Eyde to complete his process of converting air and electricity into fert ...

Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Nuclear Weapon
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions ( thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been d ...

Nazi Germany
Nazi Germany (lit. "National Socialist State"), ' (lit. "Nazi State") for short; also ' (lit. "National Socialist Germany") (officially known as the German Reich from 1933 until 1943, and the Greater German Reich from 1943 to 1945) was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a dictatorship. Under Hitler's rule, Germany quickly became a totalitarian state where nearly all aspects of life were controlled by the government. The Third Reich, meaning "Third Realm" or "Third Empire", alluded to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which Hitler and the Nazis referred to as the Thousand-Year Reich, ended in May 1945 after just 12 years when the Allies defeated Germany, ending World War II in Europe. On 30 January 1933, Hitler was appointed chancellor of Germany, the head of gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
