Reventazón Dam
The Reventazón Dam is a concrete-face rock-fill dam on the Reventazón River about southwest of Siquirres in Limón Province, Costa Rica. It was inaugurated on 16 September 2016, and its primary purpose is the production of hydroelectric power. The US$1.4 billion project and largest power station in the country has an installed capacity of 305.5 MW and is expected to provide power for 525,000 homes. Construction on the dam began in 2009. At a height of and with a structural volume of , it is the largest dam in Central America. To produce electricity, water from the reservoir is diverted about to the northeast where it reaches the power station along the Reventazón River. Due to its environmental features, like offset habitats and migration corridors for jaguars and many other species, the project could be a model for other future hydroelectric power plants.

Limón Province
Limón (), commonly known as Puerto Limón, is a district, the capital city and main hub of Limón province, as well as of the Limón canton in Costa Rica. It is the seventh largest city in Costa Rica, with a population of over 55,000, and is home of the Afro-Costa Rican community. Part of the community traces its roots to Italian, Jamaican and Chinese laborers who worked on a late nineteenth-century railroad project that connected San José to Puerto Limón. Until 1948, the Costa Rican government did not recognize Afro-Caribbean people as citizens and restricted their movement outside Limón province. As a result of this "travel ban", this Afro-Caribbean population became firmly established in the region, which influenced decisions not to move even after it was legally permitted. Nowadays, there is a significant outflow of Limón natives who move to the country's Central Valley in search for better employment and education. The Afro-Caribbean community speaks Spanish and Limones ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instituto Costarricense De Electricidad
Instituto Costarricense de Electricidad ( en, Costa Rican Institute of Electricity) (ICE) is the Costa Rican government-run electricity and telecommunications services provider. Together with the Radiographic Costarricense SA (RACSA) and Compañía Nacional de Fuerza y Luz (CNFL), they form the ICE Group. ICE was founded on 8 April 1949 by Decree-Law No. 449, after the Costa Rican Civil War of 1948, in order to solve the problems of power shortages that occurred in Costa Rica in the 1940s. Since 1963, ICE provides telecommunications services throughout the country. The attempts to reform ICE throughout a set of laws in the years 1999 and 2000 generated a great social mobilization, including the 2000 Costa Rican protests. The ruling party at that time, the Social Christian Unity Party, and the main opposition, National Liberation Party, agreed to change the institution. Meanwhile, the citizen opposition reached 274 protests in 14 days. Following the Dominican Republic–Cent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reventazón River
The Reventazón River, , (), is a river in Costa Rica. Geography Reventazón River forms part of the Reventazón-Parismina drainage basin, it is long and flows into the Caribbean sea. It starts at the base of the Irazú Volcano, passing through the east side of the Central Valley, and flows through the Orosí and Turrialba Valleys. After reaching the Caribbean coastal plains it joins the Parismina River and forms what is called the Reventazón-Parismina. Economy Water supply In its upper segments, the Reventazón River is the source of 25% of the drinking water of Costa Rica's largest metropolitan area centered on San Jose. Hydropower generation The river is very important for power generation. Three reservoirs in the river, Lake Cachí (100.8 MW), Angostura (177MW) and Reventazón Dam (305.5MW) are used for generating a significant share of Costa Rica's electricity. The dam for the third reservoir, Reventazón (305MW), was completed and opened in 2016. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...

Francis-type
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines radial and axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. It became known as the Francis turbine around 1920, being named after British-American engineer James B. Francis who in 1848 created a new turbine design. Francis turbines are primarily used for producing electricity. The power output of the electric generators generally ranges from just a few kilowatts up to 1000 MW, though mini-hydro installations may be lower. The best performance is seen when the head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm. A wicket gate around the outside of the turbine's rotating runner controls the rate of water flow through the turbine for diff ...

Concrete-face Rock-fill Dam
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 earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. 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. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inauguration
In government and politics, inauguration is the process of swearing a person into office and thus making that person the incumbent. Such an inauguration commonly occurs through a formal ceremony or special event, which may also include an inaugural address by the new official. The word ''inauguration'' stems from the Latin '' augur'', which refers to the rituals of ancient Roman priests seeking to interpret if it was the will of the gods for a public official to be deemed worthy to assume office. Public office The inaugurations of public figures, especially those of political leaders, often feature lavish ceremonies in which the figure publicly takes their oath of office (sometimes called "swearing in"), often in front of a large crowd of spectators. A monarchical inauguration may take on different forms depending on the nation: they may undergo a coronation rite or may simply be required to take an oath in the presence of a country's legislature. The "inaugural address" i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, 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.

Central America
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east.
