Lindoso Reservoir
Alto Lindoso Dam ( pt, Barragem do Alto Lindoso, links=no) is a concrete double curvature arch dam on the Lima River. It is located in the municipality Ponte da Barca, in Viana do Castelo District, Portugal. The dam lies in Peneda-Gerês National Park close to the border with Spain. The reservoir created by the dam is known as Alto Lindoso reservoir or Lindoso reservoir. History Construction of the dam began in 1983. On 15 August 1991 the land behind the dam lying in Spain was compulsorily acquired by Portuguese company EDP (Electricidade de Portugal), based on an old deal between dictators General Franco of Spain and António de Oliveira Salazar of Portugal. Residents of the five villages which were going to be drowned by the dam, Aceredo, Buscalque, O Bao, A Reloeira and Lantemil, supported by left-leaning political parties, immediately began protests against the building of the dam, including a ten-day hunger strike. In the end, with no option but to move, the residents of Ace ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hunger Strike
A hunger strike is a method of non-violent resistance in which participants fast as an act of political protest, or to provoke a feeling of guilt in others, usually with the objective to achieve a specific goal, such as a policy change. Most hunger strikers will take liquids but not solid food. In cases where an entity (usually the state) has or is able to obtain custody of the hunger striker (such as a prisoner), the hunger strike is often terminated by the custodial entity through the use of force-feeding. Early history Fasting was used as a method of protesting injustice in pre-Christian Ireland, where it was known as ''Troscadh'' or ''Cealachan''. Detailed in the contemporary civic codes, it had specific rules by which it could be used. The fast was often carried out on the doorstep of the home of the offender. Scholars speculate that this was due to the high importance the culture placed on hospitality. Allowing a person to die at one's doorstep, for a wrong of which o ...

Hydraulic Head
Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum., 410 pages. See pp. 43–44., 650 pages. See p. 22. It is usually measured as a liquid surface elevation, expressed in units of length, at the entrance (or bottom) of a piezometer. In an aquifer, it can be calculated from the depth to water in a piezometric well (a specialized water well), and given information of the piezometer's elevation and screen depth. Hydraulic head can similarly be measured in a column of water using a standpipe piezometer by measuring the height of the water surface in the tube relative to a common datum. The hydraulic head can be used to determine a ''hydraulic gradient'' between two or more points. "Head" in fluid dynamics In fluid dynamics, ''head'' is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. From Bernoulli's principle, the total energy at a given point in a fluid i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volt-ampere
A volt-ampere ( SI symbol: V⋅A or V A, simplified as VA) is the unit for the apparent power in an electrical circuit. The apparent power equals the product of root mean square voltage (in volts) and root mean square current (in amperes). Volt-amperes are usually used for analyzing alternating current (AC) circuits. In direct current (DC) circuits, this product is equal to the real power, in watts. The volt-ampere is dimensionally equivalent to the watt: in SI units, 1 V⋅A = 1 W). VA rating is most used for generators and transformers (and other power handling equipment) where loads may be reactive (inductive or capacitive). Formulation For a simple electrical circuit running on direct current, the electrical current and voltage are constant. In that case, the real power (''P'', measured in watts) is the product of the electrical current (''I'', measured in amperes) and the voltage from one side of the circuit to the other (''V'', measured in volts): ...

Francis Turbine
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 d ...

Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units, International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Energy transformation, energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish people, Scottish invention, inventor, mechanical engineer, and chemist who improved the Newcomen steam engine, Newcomen engine with his own Watt steam engine, 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 (unit), newton, the rate at which Work (physics), 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 potentia ...

Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, 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 energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, 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.
