Marmelos Zero Power Plant
The Marmelos Zero Power Plant is a decommissioned hydroelectric power plant on the Paraibuna River in Juiz de Fora, Minas Gerais, Brazil. Inaugurated in 1889, plant was the first major hydroelectric power plant constructed in South America, specifically for public use. It was purchased by CEMIG in 1980 and now serves as a museum. The Marmelos IA and II downstream are still in operation and are serviced by the original dam. History Bernardo Mascarenhas (1846-1899) became a resident of Juiz de Fora and as an adult became interested in providing electricity for the city. In 1886, Mascarenhas and banker Francisco Batista de Oliveira received approval from the city to use the Marmelos Falls for electric production and they subsequently incorporated the Minas Electricity Company. In February 1889, construction on the power plant began and by August, it began to produce initial electricity. The plant was inaugurated on September 5, 1889. The power plant was supported by a long and hig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Juiz De Fora
Juiz de Fora (, '' Outsider Judge''), also known as J.F., is a city in the southeastern Brazilian state of Minas Gerais, approximately from the state border with Rio de Janeiro. According to 2020 estimates the current population is about 573,285 inhabitants. The geographical area of the municipality is . The city's location was a key factor in its economic and demographic development since it is situated between the three most important financial and economic metropolises of southeast Brazil (and also the three largest urban sprawls of the country): Rio de Janeiro (), Belo Horizonte () and São Paulo (). Major highways connect Juiz de Fora with these three metropolitan areas, the most important being the BR 040 which connects Brasília with Rio de Janeiro via Belo Horizonte. The city is built on the Paraibuna, a major tributary of the Paraíba do Sul river.

Paraibuna River (Minas Gerais)
The Paraibuna is a river in Minas Gerais state, Brazil, and a major tributary of the Paraíba do Sul. It flows through the important commercial and industrial city of Juiz de Fora. The name of the river probably comes from the Tupi "pará y b'una" signifying "great dark river". The Paraibuna has its source near Antônio Carlos in the Serra da Mantiqueira at an elevation of . It then flows northwest to southeast for through the cities of Antônio Carlos, Santos Dumont, Ewbank da Câmara, Juiz de Fora, Matias Barbosa, Simão Pereira, Belmiro Braga, Santana do Deserto and Chiador before joining the Paraíba do Sul at an elevation of {{convert, 250, m, ft. Its principal tributaries are the Preto, Peixe, and Cágado rivers. From its confluence with the Preto to its mouth on the Paraíba, it serves as the border between the states of Minas Gerais and Rio de Janeiro.

Hydroelectric
Hydroelectricity, or hydroelectric power, is 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 sources combined and also more than nuclear power. Hydropower can provide large amounts of 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.

Power Plant
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and an increasing use of renewables such as solar, wind, geothermal, and hydroelectric. History In early 1871 Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry. In 1878, a hydroelectric power station was designed and built by Wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alternator
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature.Gordon R. Selmon, ''Magnetoelectric Devices'', John Wiley and Sons, 1966 no ISBN pp. 391-393 Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines. An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators. Large 50 or 60 Hz three-phase alternators in power plants generate most of the world's electric power, which is distributed by electric power grids. History Alternating current generating ...

Energy Infrastructure Completed In 1889
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Former Hydroelectric Power Stations
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...

Museums In Minas Gerais
A museum ( ; plural museums or, rarely, musea) is a building or institution that cares for and displays a collection of artifacts and other objects of artistic, cultural, historical, or scientific importance. Many public museums make these items available for public viewing through exhibits that may be permanent or temporary. The largest museums are located in major cities throughout the world, while thousands of local museums exist in smaller cities, towns, and rural areas. Museums have varying aims, ranging from the conservation and documentation of their collection, serving researchers and specialists, to catering to the general public. The goal of serving researchers is not only scientific, but intended to serve the general public. There are many types of museums, including art museums, natural history museums, science museums, war museums, and children's museums. According to the International Council of Museums (ICOM), there are more than 55,000 museums in 202 countries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
