Canals or artificial waterways are waterways or engineered channels built for drainage management or for conveyancing water transport vehicles. They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers.
Hydropower, also known as water power, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production.
Saint Anthony Falls, or the Falls of Saint Anthony located at the northeastern edge of downtown Minneapolis, Minnesota, is the only natural major waterfall on the Mississippi River. Throughout the mid-to-late 1800’s, various dams were built atop the east and west faces of the falls to support the milling industry that spurred the growth of the city of Minneapolis. In 1880, the central face of the falls was reinforced with a sloping timber apron to stop the upstream erosion of the falls. In the 1950s, the apron was rebuilt with concrete, which makes up the most visible portion of the falls today. A series of locks were constructed in the 1950s and 1960s to extend navigation to points upstream.
Pumping stations, also called pumphouses in situations such as drilled wells and drinking water, are facilities containing pumps and equipment for pumping fluids from one place to another. They are used for a variety of infrastructure systems, such as the supply of water to canals, the drainage of low-lying land, and the removal of sewage to processing sites. A pumping station is an integral part of a pumped-storage hydroelectricity installation.
The Confederate Powderworks was a gunpowder factory during the American Civil War, the only permanent structures completed by the Confederate States of America. Colonel George Washington Rains chose the old United States Arsenal site between the Canal and Savannah River in Augusta, Georgia, as a secure inland location with good rail and water connections.
The Middlesex Canal was a 27-mile (44-kilometer) barge canal connecting the Merrimack River with the port of Boston. When operational it was 30 feet wide, and 3 feet deep, with 20 locks, each 80 feet long and between 10 and 11 feet wide. It also had eight aqueducts.
Micro hydro is a type of hydroelectric power that typically produces from 5 kW to 100 kW of electricity using the natural flow of water. Installations below 5 kW are called pico hydro. These installations can provide power to an isolated home or small community, or are sometimes connected to electric power networks, particularly where net metering is offered. There are many of these installations around the world, particularly in developing nations as they can provide an economical source of energy without the purchase of fuel. Micro hydro systems complement solar PV power systems because in many areas water flow, and thus available hydro power, is highest in the winter when solar energy is at a minimum. Micro hydro is frequently accomplished with a pelton wheel for high head, low flow water supply. The installation is often just a small dammed pool, at the top of a waterfall, with several hundred feet of pipe leading to a small generator housing. In low head sites, generally water wheels and Archimedes screws are used.
The Peters Cartridge Company was a company located along the Little Miami River in Kings Mills, Ohio, which specialized in gunpowder and ammunition production. Founded in 1887 by Gershom Moore Peters, the company supplied military ammunition to various countries during both world wars. Following its demise in 1944, the site was repurposed by Columbia Records and later Seagram, before being abandoned in 1968 and falling into disrepair. Its historic buildings, built in 1916, were added to the National Register of Historic Places in 1985. A brewery and apartment complex themed to the defunct company was constructed on site in 2020, in which many structures were restored and the company's history was placed on display for guests.
Folsom Powerhouse State Historic Park is a historical site preserving an 1895 alternating current (AC) hydroelectric power station—one of the first in the United States.
Hacienda Buena Vista, also known as Hacienda Vives, was a coffee plantation located in Barrio Magueyes, Ponce, Puerto Rico. The original plantation dates from the 19th century. The plantation was started by Don Salvador de Vives in 1833.
The Holyoke Canal System is a system of power canals in Holyoke, Massachusetts. It is split into three canals based on elevation and distance from the inlet at the Holyoke Dam- the First Level Canal, Second Level Canal, and Third Level Canal. Constructed over a period between 1847 and 1892, the Canal System, along with the Dam, is recognized as a Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers for its use in the development of the Venturi meter by Clemens Herschel, the first means of measuring large-scale flows, and the McCormick-Holyoke Turbine by John B. McCormick, which doubled the efficiency of turbines to more than 80% in its time.
The Lower Prospect Canal Reserve is a heritage-listed former farm and public water supply canal and now bushy corridor and nature reserve stretching 7.7 kilometres (4.8 mi) through the heart of suburban Sydney, New South Wales, Australia. The lineal corridor stretches from Prospect Reservoir to Sydney Water Pipehead at Albert Street, Guildford with the majority of the reserve located in Greystanes, which is a suburb within the Cumberland Council area.
A powder mill was a mill where gunpowder is made from sulfur, saltpeter and charcoal.
The North Canal Historic District of Lawrence, Massachusetts, encompasses the historic industrial heart of the city. It is centered on the North Canal and the Great Stone Dam, which provided the waterpower for its many mill complexes. The canal was listed on the National Register of Historic Places in 1975, while the district was first listed in 1984, and then expanded slightly in 2009.
California Powder Works was the first American explosive powder manufacturing company west of the Rocky Mountains. When the outbreak of the Civil War cut off supplies of gunpowder to California's mining and road-building industries, a local manufacturer was needed. Originally located near Santa Cruz, California, the company was incorporated in 1861 and began manufacturing gunpowder in May 1864. For 50 years, it was a major employer in the county, employing between 150 and 275 men. The powder works was located on a flat adjacent to the San Lorenzo River, three miles upstream of Santa Cruz.
Oriental Powder Company was a gunpowder manufacturer with mills located on the Presumpscot River in Gorham and Windham, Maine. The company was one of the four largest suppliers to Union forces through the American Civil War.
Niagara Falls Hydraulic Power & Manufacturing Company was an American company, based in Niagara Falls, New York that was the first company to generate hydroelectric power from Niagara Falls in 1882. The company built upon several predecessor companies efforts to construct a canal used for hydraulic mill power. In 1918, the company merged with Niagara Falls Power Company, which later became Niagara Mohawk and in 2002 was acquired by National Grid plc.
The Schoellkopf Power Station was built on land owned by Jacob F. Schoellkopf above the Niagara Gorge near the American Falls, 1,600 feet (490 m) downriver from Rainbow Bridge. Understanding the growing need for electricity and the role of harnessing the Falls, Schoellkopf purchased the land for the hydraulic canal on May 1, 1877 for $71,000. After Schoellkopf Sr.'s death in 1903, his sons took over the operation of the power business. In 1918, Schoellkopf's Niagara Falls Hydraulic Power and Manufacturing Company merged with the Niagara Falls Power Company, which was owned by Edward Dean Adams. Much of the site is, as of 2014, occupied by the Maid of the Mist tour boat company as a maintenance area and off-season boat storage yard. The power station remains form a part of a fully accessible tourist attraction associated with Niagara Falls State Park and is connected with its Niagara Gorge hiking trail system.
Museo Hacienda Buena Vista is a historic coffee plantation farm museum in Barrio Magueyes, Ponce, Puerto Rico. The museum opened in 1986, and receives some 40,000 visitors a year. The museum has been described as "Puerto Rico's first living museum of art and science."
