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 ...

Mæl Station
Mæl Station (''Mæl stasjon'') is a railroad station located at Tinn in Telemark, Norway. It is the terminus of the Rjukan Line (''Rjukanbanen'') running through Vestfjorddalen between Mæl and Rjukan. The station is located 16 km from Rjukan and on the mouth of the river Måna in Vestfjorddalen where the river runs into Lake Tinn. This was the point where the railway cars on the line were transferred to the Tinnsjø railway ferry for transport to the Tinnoset Line. History Mæl Station was constructed based upon designs by architect, Thorvald Astrup. The station was built in 1909 when the Rjukan Line opened and was electrified in 1911. A new station building was constructed in 1917; it was named Rollag until 1921 when it had to change name because of the connection to the national railway network—there was already Rollag Station on the Numedal Line The Numedal Line () is a long railway line that runs up the Numedal valley between Kongsberg and Rødberg in Viken co ...

Norsk Transport
Hydro Transport AS was a railway company, railway- and List of ship companies, shipping company responsible for the transport of chemicals from Norsk Hydro Rjukan. A subsidiary of Norsk Hydro, the company was founded in 1907, operations ceased in 1991, while the company became defunct at the end of 2009. To transport the products to the coastal port at Skien, Norsk Hydro needed to build an extensive railway network. Cargo was stored in tank cars and transported down the Rjukan Line, Rjukanbanen to Mæl Station, Mæl, where it was transferred to the Tinnsjø railway ferry. After a ride across the lake, it was again transferred to Tinnoset Line and transported to Notodden where it was transshipped to barges and transported down the Telemark Canal. After 1919 the final stage was replaced with the Bratsberg Line; simultaneously the Tinnoset Line was nationalized and taken over by Norwegian State Railways, Norges Statsbaner.

Kristian Birkeland
Kristian Olaf Bernhard Birkeland (13 December 1867 – 15 June 1917) was a Norwegian scientist. He is best remembered for his theories of atmospheric electric currents that elucidated the nature of the aurora borealis. In order to fund his research on the aurorae, he invented the electromagnetic cannon and the Birkeland–Eyde process of fixing nitrogen from the air. Birkeland was nominated for the Nobel Prize seven times. Life and death Birkeland was born in Christiania (Oslo today) to Reinart Birkeland and Ingeborg (née Ege) and wrote his first scientific paper at the age of 18. Birkeland married Ida Charlotte Hammer in May 1905. They had no children and, due to Birkeland's preoccupation with his work, they divorced in 1911. Suffering from severe paranoia due to his use of barbital as a sleeping aid, he died under mysterious circumstances in his room in the Hotel Seiyoken in Tokyo while visiting colleagues at the University of Tokyo. A post-mortem revealed that Birkeland had ...

Heritage Railway
A heritage railway or heritage railroad (US usage) is a railway operated as living history to re-create or preserve railway scenes of the past. Heritage railways are often old railway lines preserved in a state depicting a period (or periods) in the history of rail transport. Definition The British Office of Rail and Road defines heritage railways as follows:...'lines of local interest', museum railways or tourist railways that have retained or assumed the character and appearance and operating practices of railways of former times. Several lines that operate in isolation provide genuine transport facilities, providing community links. Most lines constitute tourist or educational attractions in their own right. Much of the rolling stock and other equipment used on these systems is original and is of historic value in its own right. Many systems aim to replicate both the look and operating practices of historic former railways companies. Infrastructure Heritage railway lines ...

Electric Arc
An electric arc, or arc discharge, is an electrical breakdown of a gas that produces a prolonged electrical discharge. The electric current, current through a normally Electrical conductance, nonconductive medium such as air produces a plasma (physics), plasma; the plasma may produce visible light. An arc discharge is characterized by a lower voltage than a glow discharge and relies on thermionic emission of electrons from the electrodes supporting the arc. An archaic term is voltaic arc, as used in the phrase "voltaic arc lamp". Techniques for arc suppression can be used to reduce the duration or likelihood of arc formation. In the late 19th century, Arc lamp, electric arc lighting was in wide use for Street light#Arc lamps, public lighting. Some low-pressure electric arcs are used in many applications. For example, fluorescent lamp, fluorescent tubes, mercury, sodium, and metal-halide lamps are used for lighting; xenon arc lamps have been used for movie projectors. Electric a ...
