paragraph_text: A "beer engine" is a device for pumping beer, originally manually operated and typically used to dispense beer from a cask or container in a pub's basement or cellar.

paragraph_text: Where CHP is not used, steam turbines in power stations use surface condensers as a cold sink. The condensers are cooled by water flow from oceans, rivers, lakes, and often by cooling towers which evaporate water to provide cooling energy removal. The resulting condensed hot water output from the condenser is then put back into the boiler via a pump. A dry type cooling tower is similar to an automobile radiator and is used in locations where water is costly. Evaporative (wet) cooling towers use the rejected heat to evaporate water; this water is kept separate from the condensate, which circulates in a closed system and returns to the boiler. Such towers often have visible plumes due to the evaporated water condensing into droplets carried up by the warm air. Evaporative cooling towers need less water flow than "once-through" cooling by river or lake water; a 700 megawatt coal-fired power plant may use about 3600 cubic metres of make-up water every hour for evaporative cooling, but would need about twenty times as much if cooled by river water.[citation needed]

paragraph_text: On June 20, 1854, the United States Patent Office issued Patent No. 11,135 to O.H. Needham for a breast pump. Scientific American (1863) credits L.O. Colbin as the inventor and patent applicant of a breast pump. In 1921 - 23, engineer and chess master Edward Lasker produced a mechanical breast pump that imitated an infant's sucking action and was regarded by physicians as a marked improvement on existing hand - operated breast pumps, which failed to remove all the milk from the breast. The U.S. Patent Office issued U.S. Patent 1,644,257 for Lasker's breast pump. In 1956 Einar Egnell published his groundbreaking work, ``Viewpoints on what happens mechanically in the female breast during various methods of milk collection ''. This article provided insight into the technical aspects of milk extraction from the breast. Many Egnell SMB breast pumps designed through this research are still in operation over 50 years after publication.

paragraph_text: The London Gazette of 17 March 1691 published a patent in favour of John Lofting for a fire engine, but remarked upon and recommended another invention of his, for a beer pump:

paragraph_text: Shuman built the world’s first solar thermal power station in Maadi, Egypt, between 1912 and 1913. Shuman’s plant used parabolic troughs to power a 45–52 kilowatts (60–70 hp) engine that pumped more than 22,000 litres (4,800 imp gal; 5,800 US gal) of water per minute from the Nile River to adjacent cotton fields. Although the outbreak of World War I and the discovery of cheap oil in the 1930s discouraged the advancement of solar energy, Shuman’s vision and basic design were resurrected in the 1970s with a new wave of interest in solar thermal energy. In 1916 Shuman was quoted in the media advocating solar energy's utilization, saying:

paragraph_text: Tyazhely Sputnik was launched at 01:18:03 UTC on 4 February 1961, atop a Molniya 8K78 carrier rocket flying from Site 1/5 at the Baikonur Cosmodrome. When the upper stage ignited, cavitation in the liquid oxygen flowing through the oxidiser pump caused the pump to fail, resulting in an engine failure eight-tenths of a second after ignition. It reentered the atmosphere over Siberia on 26 February 1961.

paragraph_text: The Ottawa Waterworks Building is a historic waterworks in eastern Ottawa, Ohio, United States. Built in 1904, it is Putnam County's oldest water pumping facility; as the first significant water-related public works project in Ottawa, it enabled the creation of a municipal water system in the village. In its earliest years, the waterworks sheltered equipment used to pump water from municipal wells.

paragraph_text: The Petite Creuse (, the small Creuse) is a long river in Allier and Creuse departments, in central France. Its source is at Treignat, southeast of the village. It is a left tributary of the Creuse River into which it flows at Fresselines. The river is dammed at several locations creating valley lakes that are extensively used for recreation, such as fishing, boating and swimming. The dams are used to generate electricity and to supply water treatment plants providing drinking water to local communities.

paragraph_text: The Lam Takhong Dam (; ) is an embankment dam on the Lam Takhong River between Pak Chong District and Sikhio District in Nakhon Ratchasima Province, Thailand. The dam was originally constructed in 1974 for the purposes of irrigation and water supply but after 2002, its water storage also serves as the lower reservoir for the Lam Takhong pumped storage power plant, Thailand's first power plant of that type.

paragraph_text: The first commercially successful true engine, in that it could generate power and transmit it to a machine, was the atmospheric engine, invented by Thomas Newcomen around 1712. It was an improvement over Savery's steam pump, using a piston as proposed by Papin. Newcomen's engine was relatively inefficient, and in most cases was used for pumping water. It worked by creating a partial vacuum by condensing steam under a piston within a cylinder. It was employed for draining mine workings at depths hitherto impossible, and also for providing a reusable water supply for driving waterwheels at factories sited away from a suitable "head". Water that had passed over the wheel was pumped back up into a storage reservoir above the wheel.

paragraph_text: The Nile (Arabic: النيل ‎) is a major north - flowing river in northeastern Africa, and is commonly regarded as the longest river in the world, though some sources cite the Amazon River as the longest. The Nile, which is 6,853 km (4,258 miles) long, is an ``international ''river as its drainage basin covers eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, the Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Republic of the Sudan and Egypt. In particular, the Nile is the primary water source of Egypt and Sudan.

It receives its water from the Belmeken Reservoir and has 5 individual turbines with a nominal output of around which can deliver up to of power, as well as 2 pumps with an installed capacity of 104 MW. It is part of the Belmeken-Chaira-Sestrimo Hydropower Cascade.

paragraph_text: To prevent further loss of groundwater, Tucson has been involved in water conservation and groundwater preservation efforts, shifting away from its reliance on a series of Tucson area wells in favor of conservation, consumption-based pricing for residential and commercial water use, and new wells in the more sustainable Avra Valley aquifer, northwest of the city. An allocation from the Central Arizona Project Aqueduct (CAP), which passes more than 300 mi (480 km) across the desert from the Colorado River, has been incorporated into the city's water supply, annually providing over 20 million gallons of "recharged" water which is pumped into the ground to replenish water pumped out. Since 2001, CAP water has allowed the city to remove or turn off over 80 wells.

paragraph_text: It is now owned by the West View Water Authority and is used primarily to pump water from the Ohio River, which then goes on to be purified and is used by the surrounding communities for drinking.

paragraph_text: Bloemhoek Dam, is an earth-fill type dam located on a small river called Jordaan Spruit close to Kroonstad, Free State, province South Africa. It is part of the Vals River System. The Serfontein Dam, which is almost completely silted-up, releases water directly into the Vals River from where it is pumped into the Bloemhoek Dam, for supply to the urban area of Kroonstad. Its main purpose is for municipal and industrial use.

paragraph_text: Paris in its early history had only the Seine and Bièvre rivers for water. From 1809, the Canal de l'Ourcq provided Paris with water from less-polluted rivers to the north-east of the capital. From 1857, the civil engineer Eugène Belgrand, under Napoleon III, oversaw the construction of a series of new aqueducts that brought water from locations all around the city to several reservoirs built atop the Capital's highest points of elevation. From then on, the new reservoir system became Paris' principal source of drinking water, and the remains of the old system, pumped into lower levels of the same reservoirs, were from then on used for the cleaning of Paris' streets. This system is still a major part of Paris' modern water-supply network. Today Paris has more than 2,400 km (1,491 mi) of underground passageways dedicated to the evacuation of Paris' liquid wastes.
