CG : nm CT : Cet article, La récupération de l’énergie de la houle, traite, en deux parties, de la problématique de récupération de l’énergie de la houle. La première partie est consacrée à la caractérisation de la ressource énergétique que constitue la houle, et dans un second temps, à

GC: n CT: The Government is aware that some local authorities have introduced, or plan to introduce, a charge to anybody accessing certain household waste recycling centres (also known as civic amenity sites, tips, and dumps) to dispose of household waste and/or recycling. In its 2011 Waste Review, the Government

GC: n CT: the rotor for a typical utility-scale wind turbine includes three high-tech blades, a hub and a spinner. The blades are one of the most critical aspects for a wind turbine and are considered a strategic component by wind turbine OEMs. Most manufacturers create multiple blade types for

Lo que la huella ecológica nos indica es el área de territorio ecológicamente productivo que una población determinada necesita para obtener de forma continuada todos los bienes y servicios

CG: nf CA: Agua; Desarrollo sostenible. CT: Sabíamos que los habitantes de los territorios urbanos utilizamos una gran cantidad de agua para beber, cocinar y lavar. Pues bien, ahora sabemos con gran precisión que se emplea indirectamente un volumen mucho mayor en la producción de bienes y servicios de consumo

GC: n CT: HVDC systems can transmit more electrical power over longer distances than a similar alternating current (AC) transmission system, which means fewer transmission lines are needed, saving both money and land. In addition to significantly lowering electrical losses over long distances, HVDC transmission is also very stable and

GC: n CT: In contrast to reactive agent architectures, deliberative architectures take up a different position and emphasize a symbol-based reasoning process, which requires an agent to posses a local worldview. In line with the physical symbol system hypothesis (Newell and Simon 1976) symbol manipulation is necessary for producing general

GC: n CT: Conventional vehicles use gasoline or diesel to power an internal combustion engine. The hybrid car also uses an internal combustion engine—and can be fueled like normal cars—but has an electric motor and battery, and can be partially or wholly powered by electricity. By using both a conventional

CG : nf CT : Contrairement au photovoltaïque qui peut perdre 80% de sa puissance en quelques secondes lors de passages nuageux, les centrales solaires thermodynamiques ont une inertie thermique qui permet de limiter l’intermittence. Elles peuvent être équipées d’un stockage thermique de plusieurs heures et ainsi être exploitées lorsque

GC: n CT: Hybridization of thermal plants is a great driver to increase the CSP share in the global energy mix. Merits of the concept: Lower (~x1.8) LCOE than that of stand-alone CSP plants – Can compete with PV. Many developing countries will build CSP and coal plants, or already

GC: n CT: Hydraulic energy. Itaipu produces electricity based on hydraulic energy, in other words, using potential gravitational energy from the water, contained in an elevated reservoir. This energy is present in nature and it can be used in sharp descents or waterfalls. Before it turns into electric energy, this

GC: n CT: Darcy’s Law is an empirical relationship for liquid flow through a porous medium. A common application is groundwater flow through an aquifer. Darcy’s Law gives the relationship among the flow rate of the groundwater, the cross-sectional area of the aquifer perpendicular to the flow, the hydraulic gradient,

GC: n CT: A hydraulic free piston engine (HFPE) combines a diesel engine and a hydraulic pump into one compact component. In practical view there is only one linearly moving part in the HFPE, the piston assembly containing three parts, combustion and hydraulic pistons and piston rod. The piston assembly

GC: n CT: Hydraulic structures are anything that can be used to divert, restrict, stop, or otherwise manage the natural flow of water. They can be made from materials ranging from large rock and concrete to obscure items such as wooden timbers or tree trunks. A dam, for instance, is
