Diesel–electric Powertrain
A diesel–electric transmission, or diesel–electric powertrain, is a transmission (mechanics), transmission system powered by diesel engines for vehicles in #Road and other land vehicles, road, #Railway locomotives, rail, and #Ships, marine transport. Diesel–electric transmission is similar to petrol–electric transmission, which is powered by petrol engines. Diesel–electric transmission is used on railways by Diesel locomotive#Diesel–electric, diesel–electric locomotives and Diesel multiple unit#Diesel–electric, diesel–electric multiple units, as electric motors are able to supply full torque from 0 revolutions per minute, RPM. Diesel–electric systems are also used in marine transport, including submarines, and on some other land vehicles. Description The defining characteristic of diesel–electric transmission is that it avoids the need for a gearbox, by converting the mechanical force of the diesel engine into electrical energy (through an alternator), and ...

Metra Locomotive EMD F40PHM-2
Metra is the primary commuter rail system in the Chicago metropolitan area serving the city of Chicago and its surrounding suburbs via the Union Pacific Railroad, BNSF Railway, and other railroads. The system operates 243 train station, stations on 11 rail lines. It is the List of United States commuter rail systems by ridership, fourth busiest commuter rail system in the United States by ridership and the largest and busiest commuter rail system outside the New York City metropolitan area. In , the system had a ridership of , or about per weekday as of . The estimated busiest day for Metra ridership occurred on November 4, 2016—the day of the Chicago Cubs 2016 World Series victory rally, with a record 460,000+ passengers. Metra is the descendant of numerous passenger rail services dating to the 1850s. The present system dates to 1974, when the Illinois General Assembly established the Regional Transportation Authority (Illinois), Regional Transportation Authority (RTA) to ...

Electrical Energy
Electrical energy is the energy transferred as electric charges move between points with different electric potential, that is, as they move across a voltage, potential difference. As electric potential is lost or gained, work is done changing the energy of some system. The amount of work in Joule, joules is given by the product of the charge that has moved, in Coulomb, coulombs, and the potential difference that has been crossed, in Volt, volts. Electrical energy is usually sold by the kilowatt hour (1 kW·h = 3.6 MJ) which is the product of the power in kilowatts multiplied by running time in hours. Electric utilities measure energy using an electricity meter, which keeps a running total of the electrical energy delivered to a customer. Electric heating is an example of converting electrical energy into thermal energy. The simplest and most common type of electric heater uses electrical resistance to convert the energy. There are other ways to use electrical energy. Electri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Branobel
The Petroleum Production Company Nobel Brothers, Limited, or Branobel (short for братьев Нобель "brat'yev Nobel" – "Nobel Brothers" in Russian), was an oil company set up by Ludvig Nobel and Baron Peter von Bilderling. It operated mainly in Baku, Azerbaijan, but also in Cheleken, Turkmenistan. Originally established by Robert Nobel (who contributed 25,000 rubles) and the investments of barons Peter von Bilderling (300,000 rubles) and Standertskjöld (150,000 rubles) as a distillery in 1876, it became, during the late-19th century, one of the largest oil-companies in the world. History The Nobel Brothers Petroleum Company was an oil-producing company that had its origins in a distillery, founded by Robert and Ludvig Nobel in Baku in 1876, which, in 1879, turned into a shareholding company headquartered in St. Petersburg. The share capital of three million rubles was divided as follows: 53,7% Ludwig Nobel, 31,0% Baron Peter von Bilderling, 4,7% I.J. Zabelsk ...

Vandal (tanker)
''Vandal'' was a river tanker designed by Karl Hagelin and Johny Johnson for Branobel. Russian ''Vandal'' and French '' Petite-Pierre'', launched in 1903, were the world's first diesel-powered ships (sources disagree over which of the two, ''Vandal'' or ''Petite-Pierre'', was ''the'' first). ''Vandal'' was the first equipped with fully functional diesel-electric transmission. In the 1890s oil industry searched for an economical oil-burning engine, and the solution was found by German engineer Rudolph Diesel.Tolf, p. 168. Diesel marketed his technology to oil barons around the world;His first licensees included Vickers, Burmeister and Vain and Adolphus Busch. in February 1898 he granted exclusive licenses to build his engines in Sweden and Russia to Emanuel Nobel of the Nobel family.Tolf, p. 169. The Russian licence cost Nobel 800,000 marks in cash and stock of the newly founded Russian Diesel Company. The Saint Petersburg engine plant was a quick success; it started with di ...

Motorship
A motor ship or motor vessel is a ship propelled by an internal combustion engine, usually a diesel engine. The names of motor ships are often prefixed with MS, M/S, MV or M/V. Engines for motorships were developed during the 1890s, and by the early 20th century, motorships began to cross the waters. History The first diesel-powered motorships were launched in 1903: the Russian (the first equipped with diesel-electric transmission) and French ''Petite-Pierre''. There is disagreement over which of the two was the first. See also * Gas turbine ship (GTS) – prefix for a jet-engine/turbine-propelled ship * Steamship (SS) – a steamship is a ship propelled by a steam engine or steam turbine. The name of steam ships are often prefixed with SS or S/S * Royal Mail Ship (RMS) – Royal Mail Ship * Ship prefix A ship prefix is a combination of letters, usually abbreviations, used in front of the name of a civilian or naval ship that has historically served numerous purposes, ...

USCGC Healy (WAGB-20) North Of Alaska
USCGC ''Healy'' (WAGB-20) is the United States' largest and most technologically advanced icebreaker as well as the US Coast Guard's largest vessel. She is classified as a medium icebreaker by the Coast Guard. She is homeported in Seattle, Washington, and was commissioned in 1999. On 6 September 2001 ''Healy'' visited the North Pole for the first time. The second visit occurred on 12 September 2005. On 5 September 2015, ''Healy'' became the first unaccompanied United States surface vessel to reach the North Pole, and ''Healy's'' fourth Pole visit (and her second unaccompanied visit) happened on 30 September 2022. Construction ''Healy'' was built by Avondale Industries in New Orleans, Louisiana. The construction included a technology transfer agreement between Avondale Industries and the Finnish Kværner Masa-Yards Arctic Technology Centre, where the latter provided expertise for hull form development and propulsion line engineering based on the Finnish diesel-electric icebreake ...
