Segner Wheel
The Segner wheel or Segner turbine is a type of water turbine invented by Johann Andreas Segner in the 18th century. It uses the same principle as Hero's aeolipile. The device is placed in a suitable hole in the ground (or at the slope of a hill). The water is delivered to the top of a vertical cylinder, at the bottom of which is a rotor with specially bent pipes with nozzles (see image). Due to the hydrostatic pressure, the water is ejected from the nozzles, causing the rotor to rotate. The useful torque is transferred to a powered device through a belt and pulley system. Segner turbines, also called reaction or Scotch turbines, were built in the mid-1850s to power the inclined plane lifts along the Morris Canal in New Jersey. Today, the Segner wheel principle is used in irrigation sprinklers. Alexander Bogdanov cited this an example of an important innovation which paved the way for the development of steam engines.

Morris Canal
The Morris Canal (1829–1924) was a common carrier anthracite coal canal across northern New Jersey that connected the two industrial canals at Easton, Pennsylvania across the Delaware River from its western terminus at Phillipsburg, New Jersey to New York Harbor and New York City via its eastern terminals in Newark and on the Hudson River in Jersey City. The canal was sometimes called the Morris and Essex Canal, in error, due to confusion with the nearby and unrelated Morris and Essex Railroad. With a total elevation change of more than , the canal was considered an ingenious technological marvel for its use of water-driven inclined planes, the first in the United States, to cross the northern New Jersey hills. It was built primarily to move coal to industrializing eastern cities that had stripped their environs of wood. Completed to Newark in 1831, the canal was extended eastward to Jersey City between 1834 and 1836. In 1839, hot blast technology was married to blast furn ...

Lake Hopatcong
Lake Hopatcong is the largest freshwater body in New Jersey, United States, about in area. Located from the Delaware River and from Manhattan, New York City, the lake forms part of the border between Sussex and Morris counties in the state's northern highlands region. Lake Hopatcong was produced by damming and flooding of two ponds, known as the Great Pond and Little Pond, and the Musconetcong River, its natural outlet. Historically known as a resort lake for vacationing New Yorkers, it is now a mostly suburban residential lake. Name The exact origin of the name Hopatcong is unknown, though it is most commonly attributed to the Lenape Indian word for "stone water," or "stone over water". Some linguists believe "Hopatcong" to be a derivative of the Lenape word ''hapakonoesson'', meaning "pipe stone". One explanation of the origin of the word ''Hopatcong'' is that it was a derivation from the Lenni Lenape word ''Huppakong'' meaning "honey waters of many coves," but this wording ...

Steam Engines
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Bogdanov
Alexander Aleksandrovich Bogdanov (russian: Алекса́ндр Алекса́ндрович Богда́нов; – 7 April 1928), born Alexander Malinovsky, was a Russian and later Soviet physician, philosopher, science fiction writer, and Bolshevik revolutionary. He was a key figure in the early history of the Russian Social Democratic Labor Party (later the Communist Party of the Soviet Union), originally established 1898, and of its Bolshevik faction. Bogdanov co-founded the Bolsheviks in 1903, when they split with the Menshevik faction. He was a rival within the Bolsheviks to Vladimir Lenin (1870–1924), until being expelled in 1909 and founding his own faction Vpered. Following the Russian Revolutions of 1917, when the Bolsheviks came to power in the collapsing Russian Republic, during the first decade of the subsequent Soviet Union in the 1920s, he was an influential opponent of the Bolshevik government and Lenin from a Marxist leftist perspective.

Irrigation Sprinkler
An irrigation sprinkler (also known as a water sprinkler or simply a sprinkler) is a device used to irrigate (water) agricultural crops, lawns, landscapes, golf courses, and other areas. They are also used for cooling and for the control of airborne dust. Sprinkler irrigation is the method of applying water in a controlled manner in way similar to rainfall. The water is distributed through a network that may consist of pumps, valves, pipes, and sprinklers. Irrigation sprinklers can be used for residential, industrial, and agricultural usage. It is useful on uneven land where sufficient water is not available as well as on sandy soil. The perpendicular pipes, having rotating nozzles on top, are joined to the main pipeline at regular intervals. When water is pressurized through the main pipe it escapes from the rotating nozzles. It gets sprinkled on the crop. In sprinkler or overhead irrigation, water is piped to one more central locations within the field and distributed by overhe ...

Canal Inclined Plane
An inclined plane is a type of cable railway used on some canals for raising boats between different water levels. Boats may be conveyed afloat, in caissons, or may be carried in cradles or slings. History Inclined planes have evolved over the centuries. Some of the first were used by the Egyptians to bypass waterfalls on the Nile. These consisted of wooden slides covered with silt which reduced friction. Timeline *600BC – The Diolkos, an early Greek inclined plane, was in use. *385AD – Inclined planes were in use on the Grand Canal in China. *1167 – Nieuwedamme ''overtoom'' (a simple type of incline) was built at Ypres. *1568 – Wagon of Zafosina in use near Venice. *1777 – 3 inclined planes or 'dry wherries' began operation on Dukart's Canal, near Coalisland, in the south-east of County Tyrone in Ulster.''Hadfield's British Canals'' eighth edition Joseph Boughey Page 49 *1788 – An inclined plane was built by William Reynolds and used, for the first time in Engl ...

Water Turbine
A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation. Water turbines are mostly found in dams to generate electric power from water potential energy. History Water wheels have been used for hundreds of years for industrial power. Their main shortcoming is size, which limits the flow rate and head that can be harnessed. The migration from water wheels to modern turbines took about one hundred years. Development occurred during the Industrial revolution, using scientific principles and methods. They also made extensive use of new materials and manufacturing methods developed at the time. Swirl The word turbine was introduced by the French engineer Claude Burdin in the early 19th century and is derived from the Greek word "τύρβη" ...
