Keri (island)
Keri ( sv, Kockskär) is a Estonian island in the Gulf of Finland. It is located about 6 km north of the island Prangli, and is one of the northernmost islands of Estonia. Keri is the site of the notable Keri Lighthouse. Keri was first mentioned in 1623. Keri has long been situated by important sea routes. Therefore, in 1719 a lighthouse was erected there on the order of Peter the Great. The present lighthouse was built in 1803. During a well drilling in 1902 natural gas was discovered. From 1906 to 1912 the gas was used to power the lighthouse and heat the other buildings on the island. During that time it was the only lighthouse in the world to be powered by natural gas. In 1912 after a seismic impulse the gas flow stopped. The island has been inhabited only by the families of the lighthouse keepers. The last keeper left the island in September 2002. Since then the lighthouse operates automatically; the power is derived from a wind turbine and solar panels. On June 14, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keri Lighthouse
__NOTOC__ Keri Lighthouse ( Estonian: ''Keri tuletorn'') (previously known as Kokskäri Lighthouse) is a lighthouse in the Gulf of Finland on Keri Island. The light itself is at an elevation of above sea level, while the lighthouse itself is tall. History The present-day lighthouse was built in 1858. It is a red metal cylinder topped with the lantern room and balcony which rests upon a cylindrical stone base. This light is computer controlled, powered by solar cells and batteries. The original wooden lighthouse was built in 1724. It was rebuilt in the early 19th century with a stone base topped with a wooden tower. From 1907 to 1912 it was the only lighthouse in the world to be powered by natural gas. In 1990 the stone base began to collapse and steel reinforcements were installed. In 2007 an internet camera was installed followed by an internet weather station in 2009. Specifications During hours of darkness the light cycles with the following sequence: 13 sec ...

Peter The Great
Peter I ( – ), most commonly known as Peter the Great,) or Pyotr Alekséyevich ( rus, Пётр Алексе́евич, p=ˈpʲɵtr ɐlʲɪˈksʲejɪvʲɪtɕ, , group=pron was a Russian monarch who ruled the Tsardom of Russia from to 1721 and subsequently the Russian Empire until his death in 1725, jointly ruling with his elder half-brother, Ivan V until 1696. He is primarily credited with the modernisation of the country, transforming it into a European power. Through a number of successful wars, he captured ports at Azov and the Baltic Sea, laying the groundwork for the Imperial Russian Navy, ending uncontested Swedish supremacy in the Baltic and beginning the Tsardom's expansion into a much larger empire that became a major European power. He led a cultural revolution that replaced some of the traditionalist and medieval social and political systems with ones that were modern, scientific, Westernised and based on the Enlightenment. Peter's reforms had a lasting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ilyushin DB-3
The Ilyushin DB-3, where "DB" stands for ''Dalniy Bombardirovschik'' (Russian: Дальний бомбардировщик) meaning "long-range bomber", was a Soviet bomber aircraft of World War II. It was a twin-engined, low-wing monoplane that first flew in 1935. 1,528 were built. The DB-3 was the precursor of the Ilyushin Il-4 (originally designated DB-3F). Design and development The genesis of the DB-3 lay in the BB-2, Sergey Ilyushin's failed competitor to the Tupolev SB. Ilyushin was able to salvage the work and time invested in the BB-2's design by recasting it as a long-range bomber, again competing against a Tupolev design, the DB-2, to meet the stringent requirements of an aircraft capable of delivering a bombload to a range of at a maximum speed no less than . He had redesigned the BB-2 to take advantage of the radial Gnome-Rhône Mistral Major 14Kdrs engine, for which the Soviets had purchased a license in 1934 as the M-85, and had begun construction of the prototype ...

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Kaleva (airplane)
''Kaleva'' was a civilian Junkers Ju 52 passenger and transport airplane belonging to the Finnish carrier Aero O/Y. On 14 June 1940, as Flight 1631 from Tallinn in Estonia to Helsinki in Finland, the aircraft was shot down over the Gulf of Finland by two Soviet Ilyushin DB-3 bombers, killing all nine on board. The incident occurred during the Interim Peace between the Soviet Union and Finland, and at the outset of the Soviet occupation of Estonia. It was the second civilian airliner in history to be shot down in flight by hostile aircraft. Incident A few minutes after taking off from Tallinn, Aero Flight 1631 was joined at close range by two Soviet DB-3T torpedo bombers. The bombers opened fire with their machine guns and badly damaged ''Kaleva'', making it crash into the water a few kilometers northeast of Keri Lighthouse. All nine passengers and crew members on board were killed. Estonian fishermen had witnessed the attack and crash of the plane. Shortly after the cr ...

Solar Panels
A solar cell panel, solar electric panel, photo-voltaic (PV) module, PV panel or solar panel is an assembly of photovoltaic solar cells mounted in a (usually rectangular) frame, and a neatly organised collection of PV panels is called a photovoltaic system or solar array. Solar panels capture sunlight as a source of radiant energy, which is converted into electric energy in the form of direct current (DC) electricity. Arrays of a photovoltaic system can be used to generate solar electricity that supplies electrical equipment directly, or feeds power back into an alternate current (AC) grid via an inverter system. History In 1839, the ability of some materials to create an electrical charge from light exposure was first observed by the French physicist Edmond Becquerel. Though these initial solar panels were too inefficient for even simple electric devices, they were used as an instrument to measure light. The observation by Becquerel was not replicated again until 1873 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Turbine
A wind turbine is a device that converts the kinetic energy of wind into electrical energy. Hundreds of thousands of large turbines, in installations known as wind farms, now generate over 650 gigawatts of power, with 60 GW added each year. Wind turbines are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels. One study claimed that, wind had the "lowest relative greenhouse gas emissions, the least water consumption demands and the most favorable social impacts" compared to photovoltaic, hydro, geothermal, coal and gas energy sources. Smaller wind turbines are used for applications such as battery charging for auxiliary power for boats or caravans, and to power traffic warning signs. Larger turbines can contribute to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Wind turbines are manufactured in a wide range of ...

Lighthouse Keeper
A lighthouse keeper or lightkeeper is a person responsible for tending and caring for a lighthouse, particularly the light and lens in the days when oil lamps and clockwork mechanisms were used. Lighthouse keepers were sometimes referred to as "wickies" because of their job trimming the wicks. Duties and functions Historically, lighthouse keepers were needed to trim the wicks, replenish fuel, wind clockworks and perform maintenance tasks such as cleaning lenses and windows. They were also responsible for the fog signal and the weather station, and played a major role in search and rescue at sea. Because most lighthouses are located in remote, isolated or inaccessible areas on islands and coastlines, it was typical for the work of lighthouse keeper to remain within a family, passing from parents to child, all of whom lived in or near the lighthouse itself. "Stag light" was an unofficial term given to some isolated lighthouses in the United States Lighthouse Service. It meant sta ...

Natural Gas
Natural gas (also called fossil gas or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane in addition to various smaller amounts of other higher alkanes. Low levels of trace gases like carbon dioxide, nitrogen, hydrogen sulfide, and helium are also usually present. Natural gas is colorless and odorless, so odorizers such as mercaptan (which smells like sulfur or rotten eggs) are commonly added to natural gas supplies for safety so that leaks can be readily detected. Natural gas is a fossil fuel and non-renewable resource that is formed when layers of organic matter (primarily marine microorganisms) decompose under anaerobic conditions and are subjected to intense heat and pressure underground over millions of years. The energy that the decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other hydrocarbons. Natural gas can be burned fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prangli
Prangli ( sv, Vrangö) is an Estonian island in the Gulf of Finland. The first records are from 1387 when it was called ''Rango''. The first settlers came from Sweden. The Estonian culture spread to the island in the 17th century. Prangli is part of Viimsi Parish. In Kelnase is a harbour which is connected by ferry to Leppneeme on the mainland. The vegetation, especially in the east of the island is mainly fir trees. The lighthouse on Prangli was built in 1923. In 1941, the Estonian steamship ''Eestirand'' was shipwrecked off the coast of Prangli Island after a German air attack. The ''Eestirand'' was part of a fleet of ships carrying Soviet troops to Leningrad during the Soviet evacuation of Tallinn. The Estonian crew and conscripts managed to disarm Soviet military personnel aboard the ship and take control of the island, hoisting the flag of the Estonian Republic up a tall pine tree. The revolt saved approximately 2,700 conscripts, most of which were Estonian, from being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Finland
The Gulf of Finland ( fi, Suomenlahti; et, Soome laht; rus, Фи́нский зали́в, r=Finskiy zaliv, p=ˈfʲinskʲɪj zɐˈlʲif; sv, Finska viken) is the easternmost arm of the Baltic Sea. It extends between Finland to the north and Estonia to the south, to Saint Petersburg in Russia to the east, where the river Neva drains into it. Other major cities around the gulf include Helsinki and Tallinn. The eastern parts of the Gulf of Finland belong to Russia, and some of Russia's most important oil harbors are located farthest in, near Saint Petersburg (including Primorsk). As the seaway to Saint Petersburg, the Gulf of Finland has been and continues to be of considerable strategic importance to Russia. Some of the environmental problems affecting the Baltic Sea are at their most pronounced in the shallow gulf. Proposals for a tunnel through the gulf have been made. Geography The gulf has an area of . The length (from the Hanko Peninsula to Saint Petersburg) is and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Island
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
