A windmill is a structure that converts wind power into rotational energy by means of vanes called sails or blades, specifically to mill grain (gristmills), but the term is also extended to windpumps, wind turbines and other applications. Windmills were used throughout the high medieval and early modern periods; the horizontal or panemone windmill first appeared in Greater Iran during the 9th century, the vertical windmill in northwestern Europe in the 12th century.
Columbus is a city in and the county seat of Platte County, in the state of Nebraska in the Midwestern United States. The population was 22,111 at the 2010 census.
A power tool is a tool that is actuated by an additional power source and mechanism other than the solely manual labor used with hand tools. The most common types of power tools use electric motors. Internal combustion engines and compressed air are also commonly used. Other power sources include steam engines, direct burning of fuels and propellants, such as in powder-actuated tools, or even natural power sources such as wind or moving water. Tools directly driven by animal power are not generally considered power tools.
A machine tool is a machine for handling or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformation. Machine tools employ some sort of tool that does the cutting or shaping. All machine tools have some means of constraining the workpiece and provide a guided movement of the parts of the machine. Thus the relative movement between the workpiece and the cutting tool is controlled or constrained by the machine to at least some extent, rather than being entirely "offhand" or "freehand". It is a power driven metal cutting machine which assists in managing the needed relative motion between cutting tool and the job that changes the size and shape of the job material.
Metalworking is the process of working with metals to create individual parts, assemblies, or large-scale structures. The term covers a wide range of work from large ships and bridges to precise engine parts and delicate jewelry. It therefore includes a correspondingly wide range of skills, processes, and tools.
A stationary engine is an engine whose framework does not move. They are used to drive immobile equipment, such as pumps, generators, mills or factory machinery. The term usually refers to large immobile reciprocating engines, principally stationary steam engines and, to some extent, stationary internal combustion engines. Other large immobile power sources, such as steam turbines, gas turbines, and large electric motors, are categorized separately.
The Eli Whitney Museum, in Hamden, Connecticut, is an experimental learning workshop for students, teachers, and families. The museum's main building is located on a portion of the Eli Whitney Gun Factory site, a gun factory erected by Eli Whitney in 1798. The museum focuses on teaching experiments that are the roots of design and invention, featuring hands-on building projects and exhibits on Whitney and A. C. Gilbert.
A line shaft is a power driven rotating shaft for power transmission that was used extensively from the Industrial Revolution until the early 20th century. Prior to the widespread use of electric motors small enough to be connected directly to each piece of machinery, line shafting was used to distribute power from a large central power source to machinery throughout a workshop or an industrial complex. The central power source could be a water wheel, turbine, windmill, animal power or a steam engine. Power was distributed from the shaft to the machinery by a system of belts, pulleys and gears known as millwork.
Arbor Lodge State Historical Park and Arboretum is a mansion and arboretum located at 2600 Arbor Avenue, Nebraska City, Nebraska, United States. The park is a National Historic Landmark listed on the National Register of Historic Places since 1969.

The Colt Armory is a historic factory complex for the manufacture of firearms, created by Samuel Colt. It is located in Hartford, Connecticut along the Connecticut River, and as of 2008 is part of the Coltsville Historic District, named a National Historic Landmark District. It is slated to become part of Coltsville National Historical Park, now undergoing planning by the National Park Service.
The American Wind Power Center is a museum of wind power in Lubbock, Texas. Located on 28 acres (110,000 m2) of city park land east of downtown Lubbock, the museum has more than 160 American style windmills on exhibition.
Boyd's Windmill, also known as Boyd's Wind Grist Mill, is a historic smock mill at Paradise Valley Park on Prospect Avenue in Middletown, Rhode Island. John Peterson built the windmill on Old Mill Lane in Portsmouth, Rhode Island in 1810, and William Boyd purchased it in 1815. It originally had four common sails, but four more were added by the family. The mill is a timber-frame structure, octagonal in shape, and about 30 feet (9.1 m) tall, with a rotating cap powered by eight vanes with canvas sheets. The grindstones in the middle of the mill are Fall River granite; the upper one, which is connected to the power mechanisms, rotates six times for each turn of the mill's main shaft. In 1916 Benjamin Boyd removed the original vanes and powered the mill using a gasoline engine. It is one of only two historic windmills to survive on Aquidneck Island.
The Bailey Farm Windmill is an historic windmill on Maine State Route 16, north of the village of North Anson, Maine. Built in 1905, it is an architecturally distinctive local landmark, with an octagonal frame and a copper-domed roof. It was listed on the National Register of Historic Places in 1988.
Iron Turbine Windmill is a historic windmill at 415 W. Gurley Street, on the grounds of the Sharlot Hall Museum in Prescott, Arizona. It is technically a windpump, but the American term is windmill.
This is a list of the National Register of Historic Places listings in Otoe County, Nebraska.
The Otoe County Courthouse is home to the county seat of Otoe County, Nebraska in Nebraska City, Nebraska. The building contains both the Nebraska City Court and the Otoe County Court along with the government and law enforcement offices of both. The building sits at 1021 Central Avenue in Nebraska City.

The Chapin Mine Steam Pump Engine, also known as The Cornish Pump, is a steam-driven pump located at the corner of Kent Street and Kimberly Avenue in Iron Mountain, Michigan, USA. It is the largest reciprocating steam-driven engine ever built in the United States. It was listed on the National Register of Historic Places in 1981 and designated a Michigan State Historic Site in 1958.
The Nelson Farm is a historic farmstead in rural Merrick County, in the east central part of the state of Nebraska in the Midwestern United States.
