São Paulo Tramway, Light And Power Company
São Paulo Tramway, Light and Power Company, also known as Light São Paulo or simply Light (), was a privately owned utility company operating in São Paulo, Brazil from 1899 until 1981. History Canadians William Mackenzie and Frederick Stark Pearson founded the São Paulo Tramway, Light and Power Company in 1899. In 1900 Light São Paulo began operating the first tram line in the city of São Paulo which ran to Barra Funda. Work began in 1901 on the hydroelectric plant in Santana de Parnaíba. It opened in 1905. In 1905 the company installed the first electric street lights on Rua Barão de Itapetininga. In 1906 the company constructed a reservoir at Guarapiranga. In 1907 they installed 50 more lights on Direita Street, Rua 15 de Novembro, and Rua São Bento. The company signed a contract with the state of São Paulo for the first time in 1911. By 1916 they had installed 8,605 gas lights and 864 electric street lamps in the city. In 1927 the company won a governm ...

Privately Held Company
A privately held company (or simply a private company) is a company whose Stock, shares and related rights or obligations are not offered for public subscription or publicly negotiated in their respective listed markets. Instead, the Private equity, company's stock is offered, owned, traded or exchanged privately, also known as "over-the-counter (finance), over-the-counter". Related terms are unlisted organisation, unquoted company and private equity. Private companies are often less well-known than their public company, publicly traded counterparts but still have major importance in the world's economy. For example, in 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for $1.8 trillion in revenues and employed 6.2 million people, according to ''Forbes''. In general, all companies that are not owned by the government are classified as private enterprises. This definition encompasses both publ ...

Tietê River
The Tietê River ( ) is a Brazilian river in the state of São Paulo. The first known use of the name Tietê was on a map published in 1748 by d’Anville. The name means "truthful river", or "truthful waters”, in Tupi. The Tietê River is a historically significant and economically important river, which stretches 450 kilometers and allows for navigation of barges carrying various goods. Pollution of the Tietê River began subtly in the 1920s, but it has worsened significantly over time. In September 2010, National Geographic identified the river as the most polluted in Brazil. Despite efforts to clean up the river, it still suffers from pollution and environmental degradation, and some species are threatened, or possibly extinct. Source The headwaters are in the Serra do Mar, to the east of São Paulo. Salesópolis hydroelectric station One of the first hydroelectric power stations constructed in Brazil, "Usina Parque de Salesópolis", constructed in 1912 by the ...

Electric Power Companies Of Brazil
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing with electrical c ...

Alexandre Mackenzie Building
The Alexandre Mackenzie Building ( Portuguese: ''Edifício Alexandre Mackenzie''), also known as the Light Building (''Prédio da Light''), is a construction located in the central area of the city of São Paulo, between the intersection of Coronel Xavier de Toledo Street and the Viaduto do Chá, designed by the Americans Preston and Curtis and executed by Severo, Villares & Cia. Ltda. It was the headquarters of the São Paulo Tramway, Light and Power Company and later of the former state-owned Eletropaulo. It was completed in 1929 and extended in 1941. Since 1999, after careful restoration, it houses Shopping Light. Context In 1899, the São Paulo Tramway, Light and Power Company set up in rented rooms in a building on São Bento Street. Its constant growth required it to move to increasingly large areas, often in different parts of the city. There were a total of seven offices in São Paulo, which made central administration difficult. As a result, the company acquired the S ...

Light S
Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz. The visible band sits adjacent to the infrared (with longer wavelengths and lower frequencies) and the ultraviolet (with shorter wavelengths and higher frequencies), called collectively '' optical radiation''. In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum, and polarization. Its speed in vacuum, , is one of the fundamental constants of nature. All electromagnetic radiation exhibits some properties of both particles and waves. Sin ...
