Zaza Dam
The Zaza Dam is an embankment dam on the Zaza River about southwest of Sancti Spíritus in Sancti Spíritus Province, Cuba. The dam was completed in 1972 with the primary purpose of irrigation but it also supports a small hydroelectric power station. The dam's reservoir, Zaza Reservoir, has a storage capacity of , making it the largest in the country. Beginning in the 1990s, the Chinese government helped plan and install the hydroelectric power station. It contains two 1.35 MW Kaplan turbine The Kaplan turbine is a propeller-type water turbine which has adjustable blades.

Sancti Spíritus
Sancti Spíritus () is a municipality and capital city of the province of Sancti Spíritus in central Cuba and one of the oldest Cuban European settlements. Sancti Spíritus is the genitive case of Latin ''Sanctus Spiritus'' ("Holy Spirit"). History The city was founded by Diego Velázquez de Cuéllar in 1514. The city contributed men for Hernán Cortés' 1518 expedition to Mexico, including Alonso Hernandez Puertocarrero, Gonzalo de Sandoval, and Juan Velazquez de Leon.Diaz, B., 1963, The Conquest of New Spain, London: Penguin Books, Francisco Iznaga, a Basque landowner in the western portion of Cuba during the first thirty years of the colonization of Cuba, was elected mayor of Bayamo in 1540. Iznaga was the originator of a powerful lineage which finally settled in Sancti Spíritus and Trinidad, where Torre Iznaga (Iznaga Tower) is. His descendants fought for the independence of Cuba and for annexation to the U.S., from 1820 to 1900. Geography The municipality is d ...

Kaplan Turbine
The Kaplan turbine is a propeller-type water turbine which has adjustable blades. It was developed in 1913 by Austrian professor Viktor Kaplan, who combined automatically adjusted propeller blades with automatically adjusted wicket gates to achieve efficiency over a wide range of flow and water level. The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low-head applications which was not possible with Francis turbines. The head ranges from and the output ranges from 5 to 200 MW. Runner diameters are between . Turbines rotate at a constant rate, which varies from facility to facility. That rate ranges from as low as 54.5 rpm ( Albeni Falls Dam) to 450 rpm. Kaplan turbines are now widely used throughout the world in high-flow, low-head power production. Development Viktor Kaplan, living in Brno, Austria-Hungary (now in the Czech Republic), obtained his first patent for an adjustable blade propeller turbine in 19 ...

1972 Establishments In Cuba
Year 197 ( CXCVII) was a common year starting on Saturday of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Buildings And Structures In Sancti Spíritus
A building or edifice is an enclosed structure with a roof, walls and windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much artistic expression. In recent years, interest in sustainable planning and building practi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Infrastructure Completed In 2009
Energy () is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, the internal energy contained within a thermodynamic system, and rest energy associated with an object's rest mass. These are not mutually exclusive. All life, living organisms constantly take in and release energy. The Earth's climate and ecosystems processes are driven pr ...

Dams Completed In 1972
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. Egyptians also built dams, ...

Hydroelectric Power Stations In Cuba
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Sancti Spíritus Province
Sancti Spíritus () is one of the provinces of Cuba. Its capital is the identically named Sancti Spíritus. Another major city is Trinidad. Geography The southern coast of the province is flat, but the western portion of Sancti Spíritus province is mountainous. The southeast has numerous mangroves and swamps. The northern coast contains significant wetlands and protected areas such as the Bay of Buena Vista and the Caguanes National Park. The largest man-made reservoir in Cuba, the Embalse Zaza, is in Sancti Spíritus province. History During the 17th century, both Dutch and British pirates attempted to take control of what is today Sancti Spíritus province, but with little success, as the Spanish garrison held them off. From 1660 to 1680, Trinidad was plagued by pirates from Jamaica and Tortuga, and on two occasions, pirates razed the city. The provinces of Cienfuegos, Sancti Spíritus, and Villa Clara were once all part of the now defunct province of Las Villas. E ...
