Morupule Colliery
The Morupule Colliery is a coal mine located in Palapye, Botswana, owned and operated by Debswana, a partnership between the government of Botswana and De Beers. The coalfield is composed of four main seams, only one of which, the No. 1 Seam, is currently being mined, using bord and pillar mining methods. Founded in 1971 to supply the Bamangwato Concessions Ltd copper and nickel mine, operations have expanded considerably since then to supply regional power plants and industries, especially the nearby Morupule Power Station. Morupule was granted an extension to its mining lease in 1980. Expansion In January 2008, a small wash plant was commissioned with a production capacity of 120 tonnes per hour. The purpose of this plant was to supply higher quality coal to local and regional consumers. The project received support from the Botswana government, as it aimed to stimulate the local economy, produce a cleaner form of coal compared to run-of-mine coal, and offer an alternat ...

Palapye
Palapye is a growing town in Botswana, situated about halfway between Francistown and Gaborone ( from Francistown and from Gaborone). Over the years its position has made it a convenient stopover on one of Southern Africa's principal north–south rail and road routes. Located here is the Morupule Colliery, which supplies Morupule Power Station, Botswana's principal domestic source of electricity. The power station has undertaken an expansion project to increase its generation capacity in an effort to meet the country's increasing demand for electricity. Construction began in 2010. , Morupule A plant produces 132 MW of electricity, while Morupule B produces 600 MW. In 1997 Palapye was said to be the fastest-growing village in Africa, and was expected to expand its population from 30,000 to 180,000. History The Bamangwato people, under Kgosi Khama III, are widely believed to be the first people to have settled near present-day Palapye. Their capital was the settlement of Ph ...

Nickel
Nickel is a chemical element; it has symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive, but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classifie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Water Heating
Solar water heating (SWH) is water heating, heating water by sunlight, using a solar thermal collector. A variety of configurations are available at varying cost to provide solutions in different climates and latitudes. SWHs are widely used for residential and some industrial applications. A Sun-facing collector heats a working fluid that passes into a storage system for later use. SWH are active (pumped) and passive (Natural convection, convection-driven). They use water only, or both water and a working fluid. They are heated directly or via light-concentrating mirrors. They operate independently or as hybrids with electric or gas heaters. In large-scale installations, mirrors may concentrate sunlight into a smaller collector. At the end of 2023, global solar hot water thermal capacity was 560 GWth, GWth, a 3% increase from 2022. The market is dominated by Solar power in China, China, the Solar power in the United States, United States and Solar power in Turkey, Turkey. Barbad ...

Disturbed Ground
In ecology, a disturbance is a change in environmental conditions that causes a pronounced change in an ecosystem. Disturbances often act quickly and with great effect, to alter the physical structure or arrangement of biotic and abiotic elements. A disturbance can also occur over a long period of time and can impact the biodiversity within an ecosystem. Ecological disturbances include fires, flooding, storms, insect outbreaks, trampling, human presence, earthquakes, plant diseases, infestations, volcanic eruptions, impact events, etc. Not only invasive species can have a profound effect on an ecosystem, native species can also cause disturbance by their behavior. Disturbance forces can have profound immediate effects on ecosystems and can, accordingly, greatly alter the natural community’s population size or species richness. Because of these and the impacts on populations, disturbance determines the future shifts in dominance, various species successively becoming domin ...

North-South Carrier
The North-South Carrier (NSC) is a pipeline in Botswana that carries raw water south for a distance of to the capital city of Gaborone. Phase 1 was completed in 2000. Phase 2 of the NSC, under construction, will duplicate the pipeline to carry water from the Dikgatlhong Dam, which was completed in 2012. A proposed extension to deliver water from the Zambezi would add another to the total pipeline length. The NSC is the largest engineering project ever undertaken in Botswana. Climate Botswana has an arid climate, with little in the way of surface water supplies. Until recently, groundwater wells were used to meet about 80% of the demand for water. Some of the groundwater accumulated long ago when the climate was wetter. "Groundwater mining" is not sustainable in areas where the water is not being renewed from the surface. The more populous eastern portion of Botswana lies in the Limpopo River basin, which is considered "closed". In the South African portion of the basin, water u ...

Copper
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, ...
