Grand Excursion
The Grand Excursion was a promotional voyage by train and steamboat into the Upper Mississippi River valley, USA that first took place in June 1854. It marked the first railroad connection between the East Coast and the Mississippi River, and it included dignitaries such as former president Millard Fillmore. In 2004, 150 years later, the Grand Excursion route was retraced by both riverboats and a steam locomotive. The original Grand Excursion The original excursion of 1854 was organized to promote the opening of a new rail line between Chicago and Rock Island, Illinois. This line was the first railway link from the eastern United States to the Mississippi River, and thus a more than symbolic moment in westward expansion, allowing for commerce and westward immigration, and ultimately a complete rail line to the Pacific coast. The route took travelers overland from Chicago, Illinois to Rock Island, Illinois, then upriver to Saint Paul, Minnesota Territory on several steamships. App ...

Steam Engine
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 aeo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iowa
Iowa () is a U.S. state, state in the Midwestern United States, Midwestern region of the United States, bordered by the Mississippi River to the east and the Missouri River and Big Sioux River to the west. It is bordered by six states: Wisconsin to the northeast, Illinois to the east and southeast, Missouri to the south, Nebraska to the west, South Dakota to the northwest, and Minnesota to the north. During the 18th and early 19th centuries, Iowa was a part of Louisiana (New France), French Louisiana and Louisiana (New Spain), Spanish Louisiana; its Flag of Iowa, state flag is patterned after the flag of France. After the Louisiana Purchase, people laid the foundation for an agriculture-based economy in the heart of the Corn Belt. In the latter half of the 20th century, Iowa's agricultural economy transitioned to a diversified economy of advanced manufacturing, processing, financial services, information technology, biotechnology, and Sustainable energy, green energy productio ...
