Greenwich Power Station
Greenwich Power Station is a standby gas and formerly oil and coal-fired power station by the River Thames at Greenwich in south-east London. Originally constructed to supply power for London's tram system, since 1988 it has been London Underground's central emergency power supply, providing power if there is partial or total loss of National Grid supplies. History The power station was constructed on the riverside site of a former tram depot operated by the London Tramways Company (and before that by the Pimlico Peckham & Greenwich Street Tramway Company, taken over in 1873). An act of Parliament, the London County Council (Tramways and Improvements) Act 1902 ( 2 Edw. 7. c. ccxix), empowered London County Council to construct new tramways, improve existing ones and to "erect maintain and use a station for generating and transforming electrical energy with all necessary engines dynamos plant and machinery." The station was designed by William Edward Riley, chief archit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The O2 (London)
The O2 (formerly known as the Millennium Dome) is a large entertainment district on the Greenwich peninsula in South East London, England, including an indoor arena, a music club, a Cineworld cinema, an exhibition space, piazzas, bars, restaurants, and a guided tour to the top of the O2. It was built largely within the former Millennium Dome, a large dome-shaped canopy built to house an exhibition celebrating the turn of the third millennium; consequently ''The Dome'' remains a name in common usage for the venue. It is sometimes referred to as The O2 Arena, but that name properly refers to the indoor arena within The O2. Naming rights to the district were purchased by the mobile telephone provider O2 from its developers, Anschutz Entertainment Group (AEG), during the development of the district. AEG owns the long-term lease on the O2 Arena and surrounding leisure space. From the closure of the original Millennium Experience exhibition occupying the site, several ways of reu ...

Gas Turbine
A gas turbine or gas turbine engine is a type of Internal combustion engine#Continuous combustion, continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission (turboshaft), marine propeller or electric ...

Horizontal Coordinate System
The horizontal coordinate system is a celestial coordinate system that uses the observer's local horizon as the fundamental plane to define two angles of a spherical coordinate system: altitude and ''azimuth''. Therefore, the horizontal coordinate system is sometimes called the az/el system, the alt/az system, or the alt-azimuth system, among others. In an altazimuth mount of a telescope, the instrument's two axes follow altitude and azimuth. Definition This celestial coordinate system divides the sky into two hemispheres: The upper hemisphere, where objects are above the horizon and are visible, and the lower hemisphere, where objects are below the horizon and cannot be seen, since the Earth obstructs views of them. The great circle separating the hemispheres is called the ''celestial horizon'', which is defined as the great circle on the celestial sphere whose plane is normal to the local gravity vector (the vertical direction). In practice, the horizon can be define ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prime Meridian (Greenwich)
The Greenwich meridian is a prime meridian, a geographical reference line that passes through the Royal Observatory, Greenwich, Royal Observatory, Greenwich, in London, England. From 1884 to 1974, the Greenwich meridian (geography), meridian was the international standard prime meridian, used worldwide for timekeeping and navigation. The modern standard, the IERS Reference Meridian, is based on the Greenwich meridian, but differs slightly from it. This prime meridian (at the time, one of prime meridian, many) was first established by George Biddell Airy, Sir George Airy (in 1851). In 1883, the International Geodetic Association formally recommended to governments that the meridian through Greenwich be adopted as the international standard prime meridian. In October of the following year, at the invitation of the President of the United States, 41 delegates from 25 nations met in Washington, D.C., United States, for the International Meridian Conference. This inter-governmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Observatory, Greenwich
The Royal Observatory, Greenwich (ROG; known as the Old Royal Observatory from 1957 to 1998, when the working Royal Greenwich Observatory, RGO, temporarily moved south from Greenwich to Herstmonceux) is an observatory situated on a hill in Greenwich Park in south east London, overlooking the River Thames to the north. It played a major role in the history of astronomy and navigation, and because the Prime meridian (Greenwich), Prime Meridian passed through it, it gave its name to Greenwich Mean Time, the precursor to today's Coordinated Universal Time (UTC). The ROG has the IAU observatory code of 000, the first in the list. ROG, the National Maritime Museum, the Queen's House and the clipper ship ''Cutty Sark'' are collectively designated Royal Museums Greenwich. The observatory was commissioned in 1675 by Charles II of England, King Charles II, with the foundation stone being laid on 10 August. The old hilltop site of Greenwich Castle was chosen by Sir Christopher Wren, a for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Turbine
A steam turbine or steam turbine engine is a machine or heat engine that extracts thermal energy from pressurized steam and uses it to do mechanical work utilising a rotating output shaft. Its modern manifestation was invented by Sir Charles Parsons in 1884. It revolutionized marine propulsion and navigation to a significant extent. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The largest steam turbine ever built is the 1,770 MW Arabelle steam turbine built by Arabelle Solutions (previously GE Steam Power), two units of which will be installed at Hinkley Point C Nuclear Power Station, England. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nave
The nave () is the central part of a church, stretching from the (normally western) main entrance or rear wall, to the transepts, or in a church without transepts, to the chancel. When a church contains side aisles, as in a basilica-type building, the strict definition of the term "nave" is restricted to the central aisle. In a broader, more colloquial sense, the nave includes all areas available for the lay worshippers, including the side-aisles and transepts.Cram, Ralph Adams Nave The Catholic Encyclopedia. Vol. 10. New York: Robert Appleton Company, 1911. Accessed 13 July 2018 Either way, the nave is distinct from the area reserved for the choir and clergy. Description The nave extends from the entry—which may have a separate vestibule (the narthex)—to the chancel and may be flanked by lower side-aisles separated from the nave by an arcade. If the aisles are high and of a width comparable to the central nave, the structure is sometimes said to have three nave ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Savoy Hotel
The Savoy Hotel is a luxury hotel located in the Strand in the City of Westminster in central London, England. Built by the impresario Richard D'Oyly Carte with profits from his Gilbert and Sullivan opera productions, it opened on 6 August 1889. It was the first in the Savoy group of hotels and restaurants owned by Carte's family for over a century. The Savoy was the first hotel in Britain to introduce electric lights throughout the building, electric lifts, bathrooms in most of the lavishly furnished rooms, constant hot and cold running water and many other innovations. Carte hired César Ritz as manager and Auguste Escoffier as '' chef de cuisine''; they established an unprecedented standard of quality in hotel service, entertainment and elegant dining, attracting royalty and other rich and powerful guests and diners.
