SS Appomattox
The SS ''Appomattox'' was a wooden-hulled, American Great Lakes freighter that ran aground on Lake Michigan, off Atwater Beach off the coast of Shorewood, Wisconsin in Milwaukee County, Wisconsin, United States in 1905. On January 20, 2005 the remnants of the ''Appomattox'' were listed on the National Register of Historic Places. With . History The ''Appomattox'' (Official number 116682) was built in 1896 in West Bay City, Michigan by the shipyard owned by master shipbuilder James Davidson who was known for his innovative wooden hulled ships. It was the largest steam powered bulk carrier ever to sail on the Great Lakes. It was built for the Davidson Steamship Company which was also owned by Captain Davidson; it was also one of the last ships he built. At an overall length of the ''Appomattox'' was one of the largest wooden ships ever built. Its hull was between its perpendiculars. Its beam was wide, and its hull was deep. It had a gross register tonnage of 2643 tons, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Longest Wooden Ships
This is a list of the world's longest wooden ships. The vessels are sorted by ship length including bowsprit, if known. Finding the world's longest wooden ship is not straightforward since there are several contenders, depending on which definitions are used. For example, some of these ships benefited from substantial iron or even steel components since the flexing of wood members can lead to significant leaking as the wood members become longer. Some of these ships were not very seaworthy, and a few sank either immediately after launch or soon thereafter. Some of the more recent large ships were never able or intended to leave their berths, and function as floating museums. Finally, not all of the claims to the title of the world's longest wooden ship are credible or verifiable. A further problem is that especially wooden ships have more than one "length". The most used measure in length for registering a ship is the "length of the topmost deck" – the "length on deck" (LOD) – ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Ore
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (, 72.4% Fe), hematite (, 69.9% Fe), goethite (, 62.9% Fe), limonite (, 55% Fe) or siderite (, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. In 2011 the ''Financial Times'' quoted Christopher LaFemina, mining analyst at Barclays Capital, saying that iron ore is "more integral to the global economy than any other commodity, except perhaps oil". Sources Metallic iron is virtually unknown on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Sea Grant Program
The National Sea Grant College Program is a program of the National Oceanic and Atmospheric Administration (NOAA) within the U.S. Department of Commerce. It is a national network of 34 university-based Sea Grant programs involved in scientific research, education, training, and extension projects geared toward the conservation and practical use of the coasts, Great Lakes, and other marine areas. The program is administered by the National Oceanic and Atmospheric Administration (NOAA) with the national office located in Silver Spring, Maryland. There are Sea Grant programs located in every coastal and Great Lakes state as well as in Puerto Rico and Guam. The program was instituted in 1966 when Congress passed the National Sea Grant College Program Act. Sea Grant programs and colleges are not to be confused with land-grant colleges (a program instituted in 1862), space-grant colleges (instituted in 1988), or sun-grant colleges (instituted in 2003), although an institution may also ...

University Of Wisconsin–Madison
A university () is an educational institution, institution of higher education, higher (or Tertiary education, tertiary) education and research which awards academic degrees in several Discipline (academia), academic disciplines. Universities typically offer both undergraduate education, undergraduate and postgraduate education, postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation ...

Siphon
A siphon (from grc, σίφων, síphōn, "pipe, tube", also spelled nonetymologically syphon) is any of a wide variety of devices that involve the flow of liquids through tubes. In a narrower sense, the word refers particularly to a tube in an inverted "U" shape, which causes a liquid to flow upward, above the surface of a reservoir, with no pump, but powered by the fall of the liquid as it flows down the tube under the pull of gravity, then discharging at a level lower than the surface of the reservoir from which it came. There are two leading theories about how siphons cause liquid to flow uphill, against gravity, without being pumped, and powered only by gravity. The traditional theory for centuries was that gravity pulling the liquid down on the exit side of the siphon resulted in reduced pressure at the top of the siphon. Then atmospheric pressure was able to push the liquid from the upper reservoir, up into the reduced pressure at the top of the siphon, like in a baromet ...
