Surgut is a city in Khanty-Mansi Autonomous Okrug, located on the Ob River near its junction with the Irtysh River. It is one of the few cities in Russia to be larger than the capital or the administrative center of its federal subject in terms of population, economic activity, tourist traffic. Population: 348,643; the name of the city, according to one tradition, originates from the Khanty words "sur" and "gut". It was founded in 1594 by order of Tsar Feodor I Surgut at the end of the 16th century was a small fortress with two gates and five towers, one of which had a carriageway. In 1596 the Gostiny Dvor was built. In the 17th-18th centuries - one of the centers of the Russian development of Siberia; the fortification, built of strong wood, was located on the cape, so that it was impossible to approach it unnoticed either from the river or from the land. In the central square of the ancient settlement there was a cult place. Throughout the perimeter, the fortress was surrounded by a moat, blocked by the structures of the defensive system.
Outside the village there were special buildings - handicraft workshops, in particular, a smithy. By the name list of 1625 there were 222 servicemen living here. Subsequently, due to high mortality, the population of Surgut decreased. In 1627, 216 people lived, in 1635-200 people, in 1642-199. In the second half of the 17th century the population fluctuated around 200 people, by the end of the century there were 185 inhabitants in Surgut. Since 1782, the county town of the Surgut district of the Tobolsk province, has been formed. In 1785, the city's coat of arms was approved. At the end of the 18th century, in connection with the development of southern Siberian cities, lost its administrative significance. Since 1868 - district, since 1898 - the county town of Tobolsk province; the inhabitants of Surgut, like other Siberians, were on state security. The servants received an annual salary of money and salt; the inhabitants were supplied with weapons and ammunition. At the end of the 19th century, the population of Surgut was 1.1 thousand people.
The main occupation of the inhabitants was fishing, gathering of wild plants, cattle breeding, firewood harvesting. In 1835 the Cossack school was founded, in 1877 - the men's folk school, the women's parochial school operated, the weather station, the library-reading room, the people's house, since 1913 - the telegraph. Since November 3, 1923 the city became the center of the district of Tobolsk district of the Ural region. Since April 5, 1926, in connection with a small population, Surgut was transformed into a district village. In 1928, on the basis of the fish section, the first industrial enterprise was created - the fish canning factory. In 1929 a collective farm was organized, in 1930 - a forest site, in 1931 - a timber enterprise. In the 1930s in Surgut, attempts were made to extract minerals. October 23, 1934 is the first newspaper - "Organizer"; the urbanization of Surgut took place in the 1960s, when it became a center of oil and gas production. On June 25, 1965 the work settlement of Surgut was granted town status.
The city's holiday is celebrated annually on June 12. The current mayor is Vadim Nikolaevich Shuvalov. Ex-mayor Alexander Sidorov oversaw the construction of the Surgut Bridge, the longest one-tower cable-stayed bridge in the world. Within the framework of administrative divisions, it serves as the administrative center of Surgutsky District though it is not a part of it; as an administrative division, it is incorporated separately as the city of okrug significance of Surgut—an administrative unit with the status equal to that of the districts. As a municipal division, the city of okrug significance of Surgut is incorporated as Surgut Urban Okrug; the city is home to the largest port on the Ob River, the largest road/railway junction in northwest Siberia, two of the world's most powerful power plants, the SDPP-1 and SDPP-2, which produce over 7,200 megawatts and supply most of the region with cheap electricity. Surgut's economy is tied to the processing of natural gas; the most important enterprises are the oil firm Surgutgazprom.
The Surgut-2 Power Station providing Energy for the city is the largest gas-fired power station in the world. In Surgut, Tyumen Energy Retail Company, the largest energy sales company, is the guaranteeing supplier of electric power in the Tyumen region, ranked first in terms of the value of the productive supply of electricity among the energy distribution companies of the Urals Federal District and the second among the energy sales companies in Russia; the management office of OJSC TESS, the largest enterprise of the Urals Federal District, is located in the city in the sphere of complex service maintenance and reconstruction of electric power facilities. In addition, there are factories: stabilization of condensate, motor fuel. Enterprises food industry, timber industry. Manufacture of building materials. For 2013, the volume of shipped goods of own production, works performed and services by own strength for large and medium-sized producers of industrial products amounted to 100.7 billion rubles.
Russian Orthodox Church
The Russian Orthodox Church, alternatively known as the Moscow Patriarchate, is one of the autocephalous Eastern Orthodox Christian churches. The Primate of the ROC is the Patriarch of Moscow and all Rus'; the ROC, as well as the primate thereof ranks fifth in the Orthodox order of precedence below the four ancient patriarchates of the Greek Orthodox Church, those of Constantinople, Alexandria and Jerusalem. Since 15 October 2018, the ROC is not in communion with the Ecumenical Patriarch of Constantinople, having unilaterally severed ties in reaction to the establishment of the Orthodox Church of Ukraine, finalised by the Ecumenical Patriarchate on 5 January 2019; the Christianization of Kievan Rus' seen as the birth of the ROC, is believed to have occurred in 988 through the baptism of the Kievan prince Vladimir and his people by the clergy of the Ecumenical Patriarchate, whose constituent part the ROC remained for the next six centuries, while the Kievan see remained in the jurisdiction of the Ecumenical Patriarchate until 1686.
The ROC claims its exclusive jurisdiction over the Orthodox Christians, irrespective of their ethnic background, who reside in the former member republics of the Soviet Union, excluding Georgia and Armenia, although this claim is disputed in such countries as Estonia and Ukraine and parallel canonical Orthodox jurisdictions exist in those: the Estonian Apostolic Orthodox Church, the Metropolis of Bessarabia, the Orthodox Church of Ukraine, respectively. It exercises ecclesiastical jurisdiction over the autonomous Church of Japan and the Orthodox Christians resident in the People's Republic of China; the ROC branches in Belarus, Latvia and Ukraine since the 1990s enjoy various degrees of self-government, albeit short of the status of formal ecclesiastical autonomy. The ROC should not be confused with the Orthodox Church in America, another autocephalous Orthodox church, that traces its existence in North America to the time of the Russian missionaries in Alaska in the late 18th century; the ROC should not be confused with the Russian Orthodox Church Outside Russia, headquartered in the United States.
The ROCOR was instituted in the 1920s by Russian communities outside Communist Russia, which refused to recognize the authority of the Moscow Patriarchate de facto headed by Metropolitan Sergius Stragorodsky. The two churches reconciled on May 17, 2007; the Christian community that developed into what is now known as the Russian Orthodox Church is traditionally said to have been founded by the Apostle Andrew, thought to have visited Scythia and Greek colonies along the northern coast of the Black Sea. According to one of the legends, Andrew reached the future location of Kiev and foretold the foundation of a great Christian city; the spot where he erected a cross is now marked by St. Andrew's Cathedral. By the end of the first millennium AD, eastern Slavic lands started to come under the cultural influence of the Eastern Roman Empire. In 863–69, the Byzantine monks Saint Cyril and Saint Methodius, both from the region of Macedonia in the Eastern Roman Empire translated parts of the Bible into the Old Church Slavonic language for the first time, paving the way for the Christianization of the Slavs and Slavicized peoples of Eastern Europe, the Balkans and Southern Russia.
There is evidence that the first Christian bishop was sent to Novgorod from Constantinople either by Patriarch Photius or Patriarch Ignatios, c. 866–867. By the mid-10th century, there was a Christian community among Kievan nobility, under the leadership of Bulgarian and Byzantine priests, although paganism remained the dominant religion. Princess Olga of Kiev was the first ruler of Kievan Rus′, born a Christian, her grandson, Vladimir of Kiev, made Rus' a Christian state. The official Christianization of Kievan Rus' is believed to have occurred in 988 AD, when Prince Vladimir was baptised himself and ordered his people to be baptised by the priests from the Eastern Roman Empire; the Kievan church was a junior metropolitanate of the Patriarchate of Constantinople and the Ecumenical Patriarch appointed the metropolitan, a Greek, who governed the Church of Rus'. The Kiev Metropolitan's residence was located in Kiev itself, the capital of the medieval Rus' state; as Kiev was losing its political and economical significance due to the Mongol invasion, Metropolitan Maximus moved to Vladimir in 1299.
Following the tribulations of the Mongol invasion, the Russian Church was pivotal in the survival and life of the Russian state. Despite the politically motivated murders of Mikhail of Chernigov and Mikhail of Tver, the Mongols were tolerant and granted tax exemption to the church; such holy figures as Sergius of Radonezh and Metropolitan Alexis helped the country to withstand years of Mongol rule, to expand both economically and spiritually. The Trinity monastery founded by Sergius of Radonezh became the setting for the flourishing of spiritual art, exemplified by the work of Andrey Rublev, among others; the followers of Sergius founded four hundred monasteries, thus extending the geographical extent of the Grand Duchy of Moscow. In 1439, at t
Russian Census (2010)
The Russian Census of 2010 is the first census of the Russian Federation population since 2002 and the second after the dissolution of the Soviet Union. Preparations for the census began in 2007 and it took place between October 14 and October 25; the census was scheduled for October 2010, before being rescheduled for late 2013, citing financial reasons, although it was speculated that political motives were influential in the decision. However, in late 2009, Prime Minister Putin announced that the Government of Russia allocated 10.5 billion rubles in order to conduct the census as scheduled. Results showed the population to stand at 142.9 million. Since the previous 2002 census, population had decreased by 2.3 million. According to the 2010 census, urban population is 105.3 million, rural population is 37.5 million. The urbanisation rate is 73.7%. The median age is 38 years; the ethnic composition is dominated by Russians.

Public Joint Stock Company Gazprom is a large Russian company founded in 1989, which carries on the business of extraction, production and sale of natural gas. The company is majority owned by the Government of Russia, via the Federal Agency for State Property Management and Rosneftegaz; the remaining shares are listed on public stock markets of Moscow and Frankfurt. The Gazprom name is a portmanteau of the Russian words Gazovaya Promyshlennost. Gazprom is in the process of moving from Moscow to Saint Petersburg, where it is constructing Europe's tallest building for its new headquarters. Gazprom is the world`s largest oil producer, with producing oil through the largest natural gas field in the world, the Shtokman field. Gazprom was created in 1989 when the Soviet Ministry of Gas Industry was converted to a corporation, retaining its Russia-based assets. Gazprom is involved in the Russian Government's diplomatic efforts, setting of gas prices, access to pipelines. Gazprom's production fields are located around the Gulf of Ob in Western Siberia.
Plans have been made to mine the Yamal Peninsula. Gazprom's gas transport system includes 158,200 kilometres of gas trunk lines. Projects include South Stream. In 2011, Gazprom produced about 513.2 billion cubic metres of natural gas, more than seventeen percent of global gas production. Gazprom produced about 32.3 million tons of crude oil and nearly 12.1 million tons of gas condensate. The company has subsidiaries in industrial sectors including finance and aviation, majority stakes in other companies. In 1943, during World War II, the government of the Soviet Union developed a domestic gas industry. In 1965, it centralized gas exploration and distribution within the Ministry of Gas Industry. In the 1970s and 1980s, the Ministry of Gas Industry found large natural gas reserves in Siberia, the Ural region and the Volga region; the Soviet Union became a major gas producer. In August 1989, under the leadership of Viktor Chernomyrdin, the Ministry of Gas Industry was renamed the State Gas Concern Gazprom, became the Soviet Union's first state run corporate enterprise.
In late 1991, when the Soviet Union dissolved, gas industry assets were transferred to newly established national companies, such as Ukrgazprom and Turkmengazprom. Gazprom kept assets secured a monopoly in the gas sector. In December 1992, when Boris Yeltsin, the Russian President, appointed Chernomyrdin, Gazprom's Chairman, his Prime Minister, the company's political influence increased. Rem Viakhirev took the chairmanship of Gazprom's Board of Managing Committee. Following the Decree of the President of the Russian Federation of 5 November 1992 and the Resolution of the Government of Russia of 17 February 1993, Gazprom became a joint-stock company. Gazprom began to distribute shares under the voucher method.. By 1994, 33% of Gazprom's shares had been bought by 747,000 members of the public in exchange for vouchers. Fifteen percent of the stock was allocated to Gazprom employees; the state retained 40% of the shares. That amount was lowered to thirty-eight percent. Trading of Gazprom's shares was regulated.
Foreigners were prohibited from owning more than nine-percent of the shares. In October 1996, 1% of Gazprom's equity was offered for sale to foreigners as Global Depository Receipts. In 1997, Gazprom offered a bond issue of US$2.5 billion. Chernomyrdin, as Prime Minister of Russia, ensured. Gazprom evaded taxes, the Government of Russia received little in dividends. Gazprom managers and board members, such as Chernomyrdin and the Gazprom Chief Executive Officer, Rem Viakhirev, engaged in asset-stripping. Gazprom assets were shared amongst their relatives. Itera, a gas trading company received Gazprom assets. In March 1998, for reasons unrelated to his activities at Gazprom, Chernomyrdin was fired by Yeltsin. On 30 June 1998, Chernomyrdin was made Chairman of the Board of Directors of Gazprom. When, in June 2000, Vladimir Putin became the President of Russia, he acted to gain control over Russia's oligarchs, increase the Government of Russia's control in important companies through a program of national champions.
Putin fired Chernomyrdin from his position as the Chairman of the Gazprom board. The Russian Government's stock in Gazprom gave Putin the power to vote out Vyakhirev. Chernomyrdin and Vyakhirev were replaced by Alexei Miller, they were Putin's prior employees in Saint Petersburg. Putin's actions were aided by the shareholder activism of Hermitage Capital Management Chief Executive Officer William Browder, the former Russian Finance Minister Boris Fyodorov. Miller and Medvedev were to recover losses. Itera came close to bankruptcy. Itera agreed to return stolen assets to Gazprom for a fee. In June 2005, Gazpromivest Holding and Gazprom Finance B. V. subsidiaries of Gazprom, sold a 10.7399% share of their stock for $7 billion to Rosneftegaz, a state owned company. Some analysts said; the sale was completed by 25 December 2005. With the purchased stock and the thirty-eight percent share held by the State Property Committee, the Government of Russia gained control of Gazprom; the Government of Russia revoked the Gazprom twenty percent foreign ownership rule and the company
Natural gas is a occurring hydrocarbon gas mixture consisting of methane, but including varying amounts of other higher alkanes, sometimes a small percentage of carbon dioxide, hydrogen sulfide, or helium. It is formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure under the surface of the Earth over millions of years; the energy that the plants obtained from the sun is stored in the form of chemical bonds in the gas. Natural gas is a occurring hydrocarbon used as a source of energy for heating and electricity generation, it is used as a fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals. Natural gas is called a non-renewable resource. Natural gas is found in deep underground rock formations or associated with other hydrocarbon reservoirs in coal beds and as methane clathrates. Petroleum is another fossil fuel found in close proximity to and with natural gas. Most natural gas was created over time by two mechanisms: thermogenic.
Biogenic gas is created by methanogenic organisms in marshes, bogs and shallow sediments. Deeper in the earth, at greater temperature and pressure, thermogenic gas is created from buried organic material. In petroleum production gas is burnt as flare gas; the World Bank estimates that over 150 cubic kilometers of natural gas are flared or vented annually. Before natural gas can be used as a fuel, but not all, must be processed to remove impurities, including water, to meet the specifications of marketable natural gas; the by-products of this processing include: ethane, butanes and higher molecular weight hydrocarbons, hydrogen sulfide, carbon dioxide, water vapor, sometimes helium and nitrogen. Natural gas is informally referred to as "gas" when compared to other energy sources such as oil or coal. However, it is not to be confused with gasoline in North America, where the term gasoline is shortened in colloquial usage to gas. Natural gas was discovered accidentally in ancient China, as it resulted from the drilling for brines.
Natural gas was first used by the Chinese in about 500 BCE. They discovered a way to transport gas seeping from the ground in crude pipelines of bamboo to where it was used to boil salt water to extract the salt, in the Ziliujing District of Sichuan; the discovery and identification of natural gas in the Americas happened in 1626. In 1821, William Hart dug the first natural gas well at Fredonia, New York, United States, which led to the formation of the Fredonia Gas Light Company; the state of Philadelphia created the first municipally owned natural gas distribution venture in 1836. By 2009, 66 000 km³ had been used out of the total 850 000 km³ of estimated remaining recoverable reserves of natural gas. Based on an estimated 2015 world consumption rate of about 3400 km³ of gas per year, the total estimated remaining economically recoverable reserves of natural gas would last 250 years at current consumption rates. An annual increase in usage of 2–3% could result in recoverable reserves lasting less as few as 80 to 100 years.
In the 19th century, natural gas was obtained as a by-product of producing oil, since the small, light gas carbon chains came out of solution as the extracted fluids underwent pressure reduction from the reservoir to the surface, similar to uncapping a soft drink bottle where the carbon dioxide effervesces. Unwanted natural gas was a disposal problem in the active oil fields. If there was not a market for natural gas near the wellhead it was prohibitively expensive to pipe to the end user. In the 19th century and early 20th century, unwanted gas was burned off at oil fields. Today, unwanted gas associated with oil extraction is returned to the reservoir with'injection' wells while awaiting a possible future market or to repressurize the formation, which can enhance extraction rates from other wells. In regions with a high natural gas demand, pipelines are constructed when it is economically feasible to transport gas from a wellsite to an end consumer. In addition to transporting gas via pipelines for use in power generation, other end uses for natural gas include export as liquefied natural gas or conversion of natural gas into other liquid products via gas to liquids technologies.
GTL technologies can convert natural gas into liquids products such as diesel or jet fuel. A variety of GTL technologies have been developed, including Fischer–Tropsch, methanol to gasoline and syngas to gasoline plus. F–T produces a synthetic crude that can be further refined into finished products, while MTG can produce synthetic gasoline from natural gas. STG+ can produce drop-in gasoline, jet fuel and aromatic chemicals directly from natural gas via a single-loop process. In 2011, Royal Dutch Shell's 140,000 barrels per day F–T plant went into operation in Qatar. Natural gas can be "associated", or "non-associated", is found in coal beds, it sometimes contains a significant amount of ethane, propane and pentane—heavier hydrocarbons removed for commercial use prior to the methane being sold as a consumer fuel or chemical plant feedstock. Non-hydrocarbons such as carbon dioxide, nitrogen and hydrogen sulfide must be removed before the natural gas can be transported. Natural gas extracted from oil wells is called casinghead gas (whether or not produced up the a
A train station, railway station, railroad station, or depot is a railway facility or area where trains stop to load or unload passengers or freight. It consists of at least one track-side platform and a station building providing such ancillary services as ticket sales and waiting rooms. If a station is on a single-track line, it has a passing loop to facilitate traffic movements; the smallest stations are most referred to as "stops" or, in some parts of the world, as "halts". Stations elevated. Connections may be available to intersecting rail lines or other transport modes such as buses, trams or other rapid transit systems. In British English, traditional usage favours railway station or station though train station, perceived as an Americanism, is now about as common as railway station in writing. In British usage, the word station is understood to mean a railway station unless otherwise qualified. In American English, the most common term in contemporary usage is train station. In North America, the term depot is sometimes used as an alternative name for station, along with the compound forms train depot, railway depot, railroad depot, but applicable for goods, the term depot is not used in reference to vehicle maintenance facilities in American English.
The world's first recorded railway station was The Mount on the Oystermouth Railway in Swansea, which began passenger service in 1807, although the trains were horsedrawn rather than by locomotives. The two-storey Mount Clare station in Baltimore, which survives as a museum, first saw passenger service as the terminus of the horse-drawn Baltimore and Ohio Railroad on 22 May 1830; the oldest terminal station in the world was Crown Street railway station in Liverpool, built in 1830, on the locomotive hauled Liverpool to Manchester line. As the first train on the Liverpool-Manchester line left Liverpool, the station is older than the Manchester terminal at Liverpool Road; the station was the first to incorporate a train shed. The station was demolished in 1836 as the Liverpool terminal station moved to Lime Street railway station. Crown Street station was converted to a goods station terminal; the first stations had little in the way of amenities. The first stations in the modern sense were on the Liverpool and Manchester Railway, opened in 1830.
Manchester's Liverpool Road Station, the second oldest terminal station in the world, is preserved as part of the Museum of Science and Industry in Manchester. It resembles a row of Georgian houses. Early stations were sometimes built with both passenger and goods facilities, though some railway lines were goods-only or passenger-only, if a line was dual-purpose there would be a goods depot apart from the passenger station. Dual-purpose stations can sometimes still be found today, though in many cases goods facilities are restricted to major stations. In rural and remote communities across Canada and the United States, passengers wanting to board the train had to flag the train down in order for it to stop; such stations were known as "flag stops" or "flag stations". Many stations date from the 19th century and reflect the grandiose architecture of the time, lending prestige to the city as well as to railway operations. Countries where railways arrived may still have such architecture, as stations imitated 19th-century styles.
Various forms of architecture have been used in the construction of stations, from those boasting grand, Baroque- or Gothic-style edifices, to plainer utilitarian or modernist styles. Stations in Europe tended to follow British designs and were in some countries, like Italy, financed by British railway companies. Stations built more often have a similar feel to airports, with a simple, abstract style. Examples of modern stations include those on newer high-speed rail networks, such as the Shinkansen in Japan, THSR in Taiwan, TGV lines in France and ICE lines in Germany. Stations have staffed ticket sales offices, automated ticket machines, or both, although on some lines tickets are sold on board the trains. Many stations include a convenience store. Larger stations have fast-food or restaurant facilities. In some countries, stations may have a bar or pub. Other station facilities may include: toilets, left-luggage, lost-and-found and arrivals boards, luggage carts, waiting rooms, taxi ranks, bus bays and car parks.
Larger or manned stations tend to have a greater range of facilities including a station security office. These are open for travellers when there is sufficient traffic over a long enough period of time to warrant the cost. In large cities this may mean facilities available around the clock. A basic station might only have platforms, though it may still be distinguished from a halt, a stopping or halting place that may not have platforms. Many stations, either larger or smaller, offer interchange with local transportation. In many African, South American countries, Asian countries, stations are used as a place for public markets and other informal businesses; this is true on tourist routes or stations near tourist destinations. As well as providing services for passengers and loading facilities for goods, stations can sometimes have locomotive and rolling stock depots (usually with facilities for storing and refuelling rolling stock an
A helicopter is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, to fly forward and laterally; these attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of VTOL aircraft cannot perform. The English word helicopter is adapted from the French word hélicoptère, coined by Gustave Ponton d'Amécourt in 1861, which originates from the Greek helix "helix, whirl, convolution" and pteron "wing". English language nicknames for helicopter include "chopper", "copter", "helo", "heli", "whirlybird". Helicopters were developed and built during the first half-century of flight, with the Focke-Wulf Fw 61 being the first operational helicopter in 1936; some helicopters reached limited production, but it was not until 1942 that a helicopter designed by Igor Sikorsky reached full-scale production, with 131 aircraft built. Though most earlier designs used more than one main rotor, it is the single main rotor with anti-torque tail rotor configuration that has become the most common helicopter configuration.
Tandem rotor helicopters are in widespread use due to their greater payload capacity. Coaxial helicopters, tiltrotor aircraft, compound helicopters are all flying today. Quadcopter helicopters pioneered as early as 1907 in France, other types of multicopter have been developed for specialized applications such as unmanned drones; the earliest references for vertical flight came from China. Since around 400 BC, Chinese children have played with bamboo flying toys; this bamboo-copter is spun by rolling a stick attached to a rotor. The spinning creates lift, the toy flies when released; the 4th-century AD Daoist book Baopuzi by Ge Hong describes some of the ideas inherent to rotary wing aircraft. Designs similar to the Chinese helicopter toy appeared in some Renaissance paintings and other works. In the 18th and early 19th centuries Western scientists developed flying machines based on the Chinese toy, it was not until the early 1480s, when Italian polymath Leonardo da Vinci created a design for a machine that could be described as an "aerial screw", that any recorded advancement was made towards vertical flight.
His notes suggested that he built small flying models, but there were no indications for any provision to stop the rotor from making the craft rotate. As scientific knowledge increased and became more accepted, people continued to pursue the idea of vertical flight. In July 1754, Russian Mikhail Lomonosov had developed a small coaxial modeled after the Chinese top but powered by a wound-up spring device and demonstrated it to the Russian Academy of Sciences, it was powered by a spring, was suggested as a method to lift meteorological instruments. In 1783, Christian de Launoy, his mechanic, used a coaxial version of the Chinese top in a model consisting of contrarotating turkey flight feathers as rotor blades, in 1784, demonstrated it to the French Academy of Sciences. Sir George Cayley, influenced by a childhood fascination with the Chinese flying top, developed a model of feathers, similar to that of Launoy and Bienvenu, but powered by rubber bands. By the end of the century, he had progressed to using sheets of tin for rotor blades and springs for power.
His writings on his experiments and models would become influential on future aviation pioneers. Alphonse Pénaud would develop coaxial rotor model helicopter toys in 1870 powered by rubber bands. One of these toys, given as a gift by their father, would inspire the Wright brothers to pursue the dream of flight. In 1861, the word "helicopter" was coined by Gustave de Ponton d'Amécourt, a French inventor who demonstrated a small steam-powered model. While celebrated as an innovative use of a new metal, the model never lifted off the ground. D'Amecourt's linguistic contribution would survive to describe the vertical flight he had envisioned. Steam power was popular with other inventors as well. In 1878 the Italian Enrico Forlanini's unmanned vehicle powered by a steam engine, rose to a height of 12 meters, where it hovered for some 20 seconds after a vertical take-off. Emmanuel Dieuaide's steam-powered design featured counter-rotating rotors powered through a hose from a boiler on the ground. In 1887 Parisian inventor, Gustave built and flew a tethered electric model helicopter.
In July 1901, the maiden flight of Hermann Ganswindt's helicopter took place in Berlin-Schöneberg. A movie covering the event was taken by Max Skladanowsky. In 1885, Thomas Edison was given US$1,000 by James Gordon Bennett, Jr. to conduct experiments towards developing flight. Edison built a helicopter and used the paper for a stock ticker to create guncotton, with which he attempted to power an internal combustion engine; the helicopter was damaged by explosions and one of his workers was badly burned. Edison reported that it would take a motor with a ratio of three to four pounds per horsepower produced to be successful, based on his experiments. Ján Bahýľ, a Slovak inventor, adapted the internal combustion engine to power his helicopter model that reached a height of 0.5 meters in 1901. On 5 May 1905, his helicopter flew for over 1,500 meters. In 1908, Edison patented his own design for a helicopter powered by a gasoline engine with box kites attached to a mast by cables for a rotor, but it never flew.
In 1906, two French brothers and Louis Breguet, began experimenting with airfoils for helicopters. In
