Great Smog
The Great Smog of London, or Great Smog of 1952, was a severe air pollution event that affected London, England, in December 1952. A period of unusually cold weather, combined with an anticyclone and windless conditions, collected airborne pollutants—mostly arising from the use of coal—to form a thick layer of smog over the city. It lasted from Friday 5 December to Tuesday 9 December 1952, then dispersed quickly when the weather changed. The smog caused major disruption by reducing visibility and even penetrating indoor areas, far more severely than previous smog events, called " pea-soupers". Government medical reports in the weeks following the event estimated that up to 4,000 people had died as a direct result of the smog and 100,000 more were made ill by the smog's effects on the human respiratory tract. More recent research suggests that the total number of fatalities may have been considerably greater, with estimates of between 10,000 and 12,000 deaths. London had s ...

Nelson's Column
Nelson's Column is a monument in Trafalgar Square in the City of Westminster, Central London, built to commemorate Vice-Admiral Horatio Nelson's decisive victory at the Battle of Trafalgar over the combined French and Spanish navies, during which he lost his life. The monument was constructed between 1840 and 1843 to a design by William Railton at a cost of . It is a column of the Corinthian order, p.100 built from Dartmoor granite. The statue of Nelson was carved from Craigleith sandstone by sculptor Edward Hodges Baily. The four bronze lions around its base, designed by Sir Edwin Landseer, were added in 1867. The pedestal is decorated with four bronze relief panels, each square, cast from captured French guns. They depict the Battle of Cape St. Vincent, the Battle of the Nile, the Battle of Copenhagen and the death of Nelson at Trafalgar. The sculptors were Musgrave Watson, William F. Woodington, John Ternouth and John Edward Carew, respectively. The ornate capital upo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fulham Power Station
Fulham Power Station was a coal-fired power station on the north bank of the River Thames at Battersea Reach in Fulham, London Station A ran from 1901, with station B opening in 1936, until their decommissioning in 1978. History Fulham A The original power station was first commissioned in May 1901 by Fulham Borough Council. New generating equipment was added as the demand for electricity increased.

Marcus Lipton
Marcus Lipton CBE (29 October 190022 February 1978) was a British Labour Party politician. Education The son of Benjamin and Mary Lipton of Sunderland, Marcus Lipton was educated at Hudson Road Council School and Bede Grammar School in the town, before winning a scholarship to Merton College, Oxford in 1919. He was supported by a Worshipful Company of Goldsmiths exhibition bursary. He graduated with a Second in Modern History in 1922 and then studied law and was called to the bar at Gray's Inn in 1926. Career Lipton first entered politics in 1928 when he contested the London County Council elections as Liberal Party candidate for the Stepney division of Mile End. In 1934 he was elected to Stepney Borough Council. He became an alderman of Lambeth Metropolitan Borough Council in 1937 serving until 1959.

Fluorescent Lamp
A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow. A fluorescent lamp converts electrical energy into useful light much more efficiently than an incandescent lamp. The typical luminous efficacy of fluorescent lighting systems is 50–100 lumens per watt, several times the efficacy of incandescent bulbs with comparable light output. For comparison, the luminous efficacy of an incandescent bulb may only be 16 lumens per watt. Fluorescent lamp fixtures are more costly than incandescent lamps because, among other things, they require a ballast to regulate current through the lamp, but the initial cost is offset by a much lower running cost. Compact fluorescent lamps are now available in the same popular sizes as incandes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incandescent Light Bulb
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated until it glows. The filament is enclosed in a glass bulb with a vacuum or inert gas to protect the filament from oxidation. Current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections. Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external regulating equipment, have low manufacturing costs, and work equally well on either alternating current or direct current. As a result, the incandescent bulb became widely used in household and commercial lighting, for portable lighting such as table lamps, car headlamps, and flashlights, and for decorative and advertising lighting. Incandescent bulbs are much less efficient than other types of electric lighting, converting le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Underground
The London Underground (also known simply as the Underground or by its nickname the Tube) is a rapid transit system serving Greater London and some parts of the adjacent counties of Buckinghamshire, Essex and Hertfordshire in England. The Underground has its origins in the Metropolitan Railway, the world's first underground passenger railway. Opened on 10 January 1863, it is now part of the Circle, District, Hammersmith & City and Metropolitan lines. The first line to operate underground electric traction trains, the City & South London Railway in 1890, is now part of the Northern line. The network has expanded to 11 lines, and in 2020/21 was used for 296 million passenger journeys, making it one of the world's busiest metro systems. The 11 lines collectively handle up to 5 million passenger journeys a day and serve 272 stations. The system's first tunnels were built just below the ground, using the cut-and-cover method; later, smaller, roughly circular tu ...

Temperature Inversion
In meteorology, an inversion is a deviation from the normal change of an atmospheric property with altitude. It almost always refers to an inversion of the air temperature lapse rate, in which case it is called a temperature inversion. Normally, air temperature decreases with an increase in altitude, but during an inversion warmer air is held above cooler air. An inversion traps air pollution, such as smog, close to the ground. An inversion can also suppress convection by acting as a "cap". If this cap is broken for any of several reasons, convection of any moisture present can then erupt into violent thunderstorms. Temperature inversion can notoriously result in freezing rain in cold climates. Normal atmospheric conditions Usually, within the lower atmosphere (the troposphere) the air near the surface of the Earth is warmer than the air above it, largely because the atmosphere is heated from below as solar radiation warms the Earth's surface, which in turn then warms the ...

Diesel Fuel
Diesel fuel , also called diesel oil, is any liquid fuel specifically designed for use in a diesel engine, a type of internal combustion engine in which fuel ignition takes place without a spark as a result of compression of the inlet air and then injection of fuel. Therefore, diesel fuel needs good compression ignition characteristics. The most common type of diesel fuel is a specific fractional distillate of petroleum fuel oil, but alternatives that are not derived from petroleum, such as biodiesel, biomass to liquid (BTL) or gas to liquid (GTL) diesel are increasingly being developed and adopted. To distinguish these types, petroleum-derived diesel is sometimes called petrodiesel in some academic circles. In many countries, diesel fuel is standardised. For example, in the European Union, the standard for diesel fuel is EN 590. Diesel fuel has many colloquial names; most commonly, it is simply referred to as ''diesel''. In the United Kingdom, diesel fuel for on-road use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flue Gas
Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator. Quite often, the flue gas refers to the combustion exhaust gas produced at power plants. Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived from the combustion of air, carbon dioxide (), and water vapor as well as excess oxygen (also derived from the combustion air). It further contains a small percentage of a number of pollutants, such as particulate matter (like soot), carbon monoxide, nitrogen oxides, and sulfur oxides. Most fossil fuels are combusted with ambient air (as differentiated from combustion with pure oxygen). Since ambient air contains about 79 volume percent gaseous nitrogen (N2), which is essentially non-combustible, the largest part of the flue gas from most fossil-fuel combustion is uncombusted nitr ...

Met Office
The Meteorological Office, abbreviated as the Met Office, is the United Kingdom's national weather service. It is an executive agency and trading fund of the Department for Business, Energy and Industrial Strategy and is led by CEO Penelope Endersby, who took on the role as Chief Executive in December 2018 and is the first woman to do so. The Met Office makes meteorological predictions across all timescales from weather forecasts to climate change. History The Met Office was established on 1 August 1854 as a small department within the Board of Trade under Vice Admiral Robert FitzRoy as a service to mariners. The loss of the passenger vessel, the ''Royal Charter'', and 459 lives off the coast of Anglesey in a violent storm in October 1859 led to the first gale warning service. FitzRoy established a network of 15 coastal stations from which visual gale warnings could be provided for ships at sea. The new electric telegraph enabled rapid dissemination of warnings an ...

Kingston Power Station, London
Kingston Power Station was a coal-fired generating station on the Thames in Kingston upon Thames, Surrey (later Greater London). It ceased generating in 1980 and has been demolished. History The first station was built in 1893, with an original capacity of 225 kW. New generating equipment was added as the demand for electricity increased. The generating capacity, maximum load, and electricity generated and sold was as follows: The A station eventually closed in 1959. A new 'B' station was planned before World War II, opening in 1948. The Thames was used both for coal supply and ash removal, and as a source of cooling water. The new station was the first to be opened following nationalisation of the power industry, with the official opening by King George VI, the first station to receive such an honour since Barking in 1924. Technical specification In 1923 the plant comprised two 1,250 kW turbo-alternators, these were supplied from the boiler plant which produced a t ...
