Zengamina
Zengamina is a small hydroelectric power generation plant near Kalene Hill, Ikelenge District in northwestern Zambia. It was built between 2004 and 2008 at a cost of about $3 million, or $4,285 per kilowatt of power. Background Before the power plant was opened most people had no electricity, using wood or kerosene for cooking. Those who could afford it used diesel generators to provide electricity. The Zambian national electricity grid ends from the Ikelenge area. The local people were trapped in a poverty cycle, living through unsustainable slash-and-burn subsistence farming. The Zengamina project aimed to provide a reliable electrical supply with a small hydroelectrical station on the Zambezi River at a fast-moving point close to its source. The Zambezi at this location drops over a length of rapids. The potential for power generation on the Zambezi rapids was identified in 1964, but without funding nothing was done. In 2001 Dr Peter Gill, an orthopaedic surgeon in the Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kalene Hill
Kalene Hill is a community in the northwest of Zambia near a hill by the same name about to the southeast. It is part of the Ikelenge District. Kalene Hill was the site of an early medical mission. The hospital is still important to the region. Location The Kalene hill is a low ridge of Karoo sandstone. It lies in Lunda territory. It is found in the Ikelenge District on the T5 Road of Zambia. Local tradition says that a chief created it when he found his way was blocked by a huge swamp. The chief called on his ancestral spirits and dropped magic powder along the route he wanted to take. Dry land broke up from the marsh and formed the long hill of today. The hill is close to the Democratic Republic of the Congo (DRC) to the north and Angola to the west. At the hilltop is often cool. From the summit one can see far into Angola and the DRC. The Zambezi has its source near Kalene Hill at an elevation of about . To the west of the hill the land falls away steeply to the headwater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ikelenge District
Ikelenge District is a district of North-Western Province, Zambia. It was separated from Mwinilunga District in 2011. Ikelenge District is located north of Mwinilunga and contains the Kalene Hills together with the source of the Zambezi River and the Zengamina Hydroelectric Power Plant within its small area. The Zengamina Plant exists primarily because Zambia's national electricity grid does not reach the region. The main road in the region is the T5 Road, which connects Ikelenge to Mwinilunga in the south and to a border with Angola , national_anthem = " Angola Avante"() , image_map = , map_caption = , capital = Luanda , religion = , religion_year = 2020 , religion_ref = , coordina ... west of Kalene Hill.

Zambezi River
The Zambezi River (also spelled Zambeze and Zambesi) is the fourth-longest river in Africa, the longest east-flowing river in Africa and the largest flowing into the Indian Ocean from Africa. Its drainage basin covers , slightly less than half of the Nile's. The river rises in Zambia and flows through eastern Angola, along the north-eastern border of Namibia and the northern border of Botswana, then along the border between Zambia and Zimbabwe to Mozambique, where it crosses the country to empty into the Indian Ocean. The Zambezi's most noted feature is Victoria Falls. Its other falls include the Chavuma Falls at the border between Zambia and Angola, and Ngonye Falls near Sioma in western Zambia. The two main sources of hydroelectric power on the river are the Kariba Dam, which provides power to Zambia and Zimbabwe, and the Cahora Bassa Dam in Mozambique, which provides power to Mozambique and South Africa. Additionally, two smaller power stations are along the Zambezi Ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Small Hydro
Small hydro is the development of hydroelectric power on a scale suitable for local community and industry, or to contribute to distributed generation in a regional electricity grid. Exact definitions vary, but a "small hydro" project is less than 50 megawatts (MW), and can be further subdivide by scale into "mini" (<1MW), " micro" (<100 kW), "" (<10 kW). In contrast many hydroelectric projects are of enormous size, such as the generating plant at the at 22,500 megawatts or the vast multiple projects of the |
Zambia
Zambia (), officially the Republic of Zambia, is a landlocked country at the crossroads of Central Africa, Central, Southern Africa, Southern and East Africa, although it is typically referred to as being in Southern Africa at its most central point. Its neighbours are the Democratic Republic of the Congo to the north, Tanzania to the northeast, Malawi to the east, Mozambique to the southeast, Zimbabwe and Botswana to the south, Namibia to the southwest, and Angola to the west. The capital city of Zambia is Lusaka, located in the south-central part of Zambia. The nation's population of around 19.5 million is concentrated mainly around Lusaka in the south and the Copperbelt Province to the north, the core economic hubs of the country. Originally inhabited by Khoisan peoples, the region was affected by the Bantu expansion of the thirteenth century. Following the arrival of European exploration of Africa, European explorers in the eighteenth century, the British colonised the r ...

Weir
A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. Etymology There is no single definition as to what constitutes a weir and one English dictionary simply defines a weir as a small dam, likely originating from Middle English ''were'', Old English ''wer'', derivative of root of ''werian,'' meaning "to defend, dam". Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more navigable by boat. In some locations, the terms dam and weir are synonymous, but normally there is a clear distinction made between the structures. Usually, a dam is designed specifically to impound water behind ...

Headpond
A reservoir (; from French language, French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to water storage, store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an Bay, embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried storage tanks, tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural ...

Penstock
A penstock is a sluice or gate or intake structure that controls water flow, or an enclosed pipe that delivers water to hydro turbines and sewerage systems. The term is inherited from the earlier technology of mill ponds and watermills. Hydroelectric systems and dams Penstocks for hydroelectric installations are normally equipped with a gate system and a surge tank. They can be a combination of many components such as anchor block, drain valve, air bleed valve, and support piers depending on the application. Flow is regulated by turbine operation and is nil when turbines are not in service. Penstocks, particularly where used in polluted water systems, need to be maintained by hot water washing, manual cleaning, antifouling coatings, and desiccation. The term is also used in irrigation dams to refer to the channels leading to and from high-pressure sluice gates. Penstocks are also used in mine tailings dam construction. The penstock is usually situated fairly close to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Station
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and an increasing use of renewables such as solar, wind, geothermal, and hydroelectric. History In early 1871 Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry. In 1878, a hydroelectric power station was designed and built b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tailrace
A water wheel is a machine for converting the energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a wheel (usually constructed from wood or metal), with a number of blades or buckets arranged on the outside rim forming the driving car. Water wheels were still in commercial use well into the 20th century but they are no longer in common use. Uses included milling flour in gristmills, grinding wood into pulp for papermaking, hammering wrought iron, machining, ore crushing and pounding fibre for use in the manufacture of cloth. Some water wheels are fed by water from a mill pond, which is formed when a flowing stream is dammed. A channel for the water flowing to or from a water wheel is called a mill race. The race bringing water from the mill pond to the water wheel is a headrace; the one carrying water after it has left the wheel is commonly referred to as a tailrace. Waterwheels were used for various purposes from ag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross-flow Turbine
A cross-flow turbine, Bánki-Michell turbine, or Ossberger turbine''E.F. Lindsley,'' Water power for your homePopular Science, May 1977, Vol. 210, No. 5 87-93. is a water turbine developed by the Australian Anthony Michell, the Hungarian Donát Bánki and the German Fritz Ossberger. Michell obtained patents for his turbine design in 1903, and the manufacturing company Weymouth made it for many years. Ossberger's first patent was granted in 1933 ("Free Jet Turbine" 1922, Imperial Patent No. 361593 and the "Cross Flow Turbine" 1933, Imperial Patent No. 615445), and he manufactured this turbine as a standard product. Today, the company founded by Ossberger is the leading manufacturer of this type of turbine. Unlike most water turbines, which have axial or radial flows, in a cross-flow turbine the water passes through the turbine transversely, or across the turbine blades. As with a water wheel, the water is admitted at the turbine's edge. After passing to the inside of the runner, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
