L.D. Porta
Livio Dante Porta (21 March 1922 – 10 June 2003) was an Argentina, Argentine Locomotive#Steam, steam locomotive engineer. He is particularly remembered for his innovative modifications to existing locomotive systems in order to obtain better performance and Energy efficiency in transportation, energy efficiency, and reduced pollution. He developed the Kylpor ejector, Kylpor and Lempor ejector, Lempor exhaust systems. The Lemprex ejector, Lemprex was under development at the time of his death. Early years Porta was born in Paraná, Entre Ríos, and studied civil engineering, concluding his studies in 1946, at a time when steam was already giving way to diesel and electric locomotives in Europe and North America. Career Naturally, Porta's first projects were in Argentina. Taking the work of Andre Chapelon in France as his starting point, he set out to demonstrate that the steam locomotive was far from reaching its maximum potential. His first locomotive project in 1948 took ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Santa Cruz Province, Argentina
Santa Cruz Province (, , "Holy Cross") is a Provinces of Argentina, province of Argentina, located in the southern part of the country, in Patagonia. It borders Chubut Province to the north, and Chile to the west and south, with the Atlantic Ocean, Atlantic coast to the east. Santa Cruz is the second-largest province of the country (after Buenos Aires Province), and the least Population density, densely populated in mainland Argentina. The indigenous people of the province are the Tehuelches, who despite European exploration from the 16th century onwards, retained independence until the late 19th century. Soon after the Conquest of the Desert in the 1870s, the area was organised as the Territory of Santa Cruz, named after its original capital in Puerto Santa Cruz. The capital moved to Rio Gallegos in 1888 and has remained there ever since. Immigrants from various European countries came to the territory in the late 19th and early 20th century Tierra del Fuego gold rush, during a go ...

Advanced Steam Technology
Advanced steam technology (sometimes known as modern steam) reflects an approach to the technical development of the steam engine intended for a wider variety of applications than has recently been the case. Particular attention has been given to endemic problems that led to the demise of steam power in small to medium-scale commercial applications: excessive pollution, maintenance costs, labour-intensive operation, low power/weight ratio, and low overall thermal efficiency. Steam power has generally been superseded by the internal combustion engine or by electrical power drawn from an electrical grid. The only steam installations that are in widespread use are the highly efficient thermal power plants used for generating electricity on a large scale. In contrast, the proposed steam engines may be for stationary, road, rail, or marine use. Improving steam traction Although most references to "Modern Steam" apply to developments since the 1970s, certain aspects of advanced s ...

Forced Disappearance
An enforced disappearance (or forced disappearance) is the secret abduction or imprisonment of a person with the support or acquiescence of a State (polity), state followed by a refusal to acknowledge the person's fate or whereabouts with the intent of placing the victim outside the protection of the law. Often, forced disappearance implies murder whereby a victim is kidnapping, abducted, may be illegally prison, detained, and is often tortured during interrogation, ultimately killed, and the body disposed of secretly. The party committing the murder has plausible deniability as there is no evidence of the victim's death. Enforced disappearance was first recognized as a human rights issue in the 1970s as a result of Detenidos Desaparecidos, its use by military dictatorships in Latin America during the Dirty War. However, it has occurred all over the world. According to the Rome Statute of the International Criminal Court, which came into force on 1 July 2002, when committed as ...

Dirty War
The Dirty War () is the name used by the military junta or National Reorganization Process, civic-military dictatorship of Argentina () for its period of state terrorism in Argentina from 1974 to 1983. During this campaign, military and security forces and death squads in the form of the Argentine Anticommunist Alliance (AAA, or Triple A) hunted down any political dissidents and anyone believed to be associated with socialism, left-wing Peronism, or the Montoneros movement.''Political Violence and Trauma in Argentina, '' Antonius C.

Southern Fuegian Railway
The Southern Fuegian Railway () or the Train of the End of the World () is a gauge steam railway in Tierra del Fuego Province, Argentina. It was originally built as a freight line to serve the prison of Ushuaia, specifically to transport rock, sand and lumber. It now operates as a heritage railway into the Tierra del Fuego National Park and is considered the southernmost functioning railway in the world. History Origins century, Ushuaia on Isla Grande de Tierra del Fuego developed as a penal colony, with the first prisoners arriving in 1884. In 1902, work began on a proper set of buildings for the prison by inmates, and a railway on wooden rails was constructed to assist the transport of materials, mainly local rock, sand and lumber. Oxen pulled wagons along the narrow gauge of less than . In 1909, the prison governor informed the government of the need to upgrade the line. Decauville tracks at a narrow gauge were laid for use with two steam locomotives. The upgraded lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garratt Locomotive
A Garratt locomotive is a type of articulated steam locomotive invented by the engineer Herbert William Garratt that is articulated into three parts. Its boiler, firebox, and cab are mounted on a centre frame or "bridge". The two other parts, one at each end, have a pivot to support the central frame; they consist of a steam engine unit – with driving wheels, trailing wheels, valve gear, and cylinders, and above it, fuel and/or water storage. Articulation permits locomotives to negotiate curves that might restrict large rigid-framed locomotives. The design also provides more driving wheels per unit of locomotive weight, permitting operation on lightly engineered track. Garratt locomotives produced as much as twice the tractive effortTractive effort is not the same as power: it is the measurement of a force, whereas power is the rate of doing work. The locomotive with the highest tractive effort is not necessarily the most powerful. of the largest conventional locomotiv ...

5AT Advanced Technology Steam Locomotive
The 5AT Advanced Technology steam locomotive was a conceptual design conceived by the British engineer David Wardale, and first described in his 1998 definitive work on modern steam, ''The Red Devil and Other Tales from the Age of Steam.'' Wardale's purpose in putting forward the "Super Class 5 4-6-0" design concept (as he then called it) was to offer a future for steam hauled trains on the main lines in the UK on which the use of heritage traction is likely to be gradually phased out as the speed and density of commercial rail traffic increase. Work on the project was suspended in March 2012 following completion of a project Feasibility Study and subsequent failure to raise the finance needed to complete the detail design and construction of the locomotive. Proposal Wardale's proposal was for a locomotive that would: * be acceptable to the British railway authorities by conforming with the size and weight of the BR 5MT Class 4-6-0 locomotives that have operated on British mai ...

Bagasse
Bagasse ( ) is the dry pulpy fibrous material that remains after crushing sugarcane or sorghum stalks to extract their juice. It is used as a biofuel for the production of heat, energy, and electricity, and in the manufacture of pulp and building materials. Agave bagasse is similar, but is the material remnants after extracting blue agave sap. Etymology The word comes from ''bagasse'' (French) and ''bagazo'' (Spanish), meaning ''refuse'' or ''trash''. It originally referred to the material left after pressing olives, palm nuts, and grapes. The word eventually came to be used in the context of processing of plants such as sugarcane and sugar beets. Today, it usually refers to by-products of the sugarcane mill. Description Bagasse is the solid by-product when the liquid components are extracted from plants. Much of the core of those plants is a heterogeneous "pith" fibre. This fibre is primarily parenchyma tissue, along with bast, rind, or stem fibers of the sclerenchyma. Here ...

ACE 3000
The ACE 3000 was a proposed modern 4-4-4-2 coal-burning duplex drive steam locomotive design for Ross Rowland's ''ACE 3000 Project'' and for the American Coal Enterprises, the locomotive was designed by Ross Rowland and was developed by American Coal Enterprises in the late 1970s. Testing In 1985, Chesapeake and Ohio 614 was modified to do better performance under the guidance of David Wardale. For several weeks between January and February of 1985, No. 614 (renumbered to 614-T, with the "''T''" denoting ''testing'') had hauled several coal trains between Huntington, West Virginia and Hinton, West Virginia. When the 1970s came, the 1970s oil crisis had hit and it was causing problems for the railroads that had dieselized in order to cut costs and operating diesels was getting more expensive. Design Development of the modern 4-4-4-2 coal-burning steam locomotive that was classified as the ACE 3000 was done by American Coal Enterprises, which was founded to raise funds t ...
