GC: n CT: Every year, billions of dollars of energy are thrown away as waste heat. Heat is the natural by-product of energy conversion processes; both conversion of primary fuels to work or energy, and conversion of energy to work. Of the 100 quadrillion BTU’s of energy the US consumes
GC: n CT: Waste of electrical and electronic equipment (WEEE) such as computers, TV-sets, fridges and cell phones is one the fastest growing waste streams in the EU, with some 9 million tonnes generated in 2005, and expected to grow to more than 12 million tonnes by 2020. WEEE is
GC: n CT: We consider wastewater treatment as a water use because it is so interconnected with the other uses of water. Much of the water used by homes, industries, and businesses must be treated before it is released back to the environment. If the term «wastewater treatment» is confusing
GC: n CT: A tool that has been developed for the calculation of water needs for consumer products is the concept of the water footprint (WF). This tool has been introduced by Hoekstra and Hung (2002) and has been developed further by Hoekstra and Chapagain (2007, 2008). Those authors define
GC: n CT: Water hammer is a pressure surge or wave caused when a fluid (usually a liquid but sometimes also a gas) in motion is forced to stop or change direction suddenly (momentum change). As soon as steam leaves the boiler, it starts losing heat. As a result, steam
GC: n CT: A watershed is the area of land where all of the water that is under it or drains off of it goes into the same place. John Wesley Powell, scientist geographer, put it best when he said that a watershed is: «that area of land, a bounded
CG: nm CT: Concentrée au niveau des embouchures des fleuves, la capacité théorique de l’énergie osmotique au niveau mondial serait d’au moins 1 Térawatt, soit l’équivalent de 1000 réacteurs nucléaires. Cependant, les technologies permettant de récupérer cette énergie présentent d’assez faibles performances, de l’ordre de 3 Watts par mètre carré
GC: n CT: Photovoltaic solar panels produce power through generation of watts of energy. Panels come in different “strengths” or wattage levels. Solar panel sizes vary from very low wattage levels up to 280 watts worth of power. Solar systems are sold as complete installs by watt. This includes the
CG : nm CT : Le Watt crête caractérise la puissance d’un panneau photovoltaïque. En moyenne, un Watt crête correspond à la puissance d’une cellule monocristalline d’une surface d’un décimètre carré et de dimensions 100 mm x 100 mm. La puissance crête représente la puissance délivrée par le panneau au
GC: n CT: A wave power generator that can harvest energy no matter which way the sea is running has won the UK round of James Dyson’s engineering award. The Renewable Wave Power generator seeks to overcome the limitations of some current wave power technologies. These work best when struck
GC: n CT: As the climate change conference continues in The Hague, it is perhaps fitting that the world’s first commercial wave power station is going into action in Scotland. The power station, on the island of Islay, is the product of years of research into how to effectively harvest

Se representa por la letra griega Φ; sus unidades son: El weber (Wb), en el sistema internacional. El maxvelio, en el sistema
CG : nm CT : Les unités pratiques, déduites du système CGS par des multiples de 10, furent baptisées de noms d’un type nouveau, des noms de savants, considérés comme plus faciles pour les techniciens, et rendant hommage à trois savants de la science électrique : ohm pour la résistance,
GC: n CT: The units for magnetic flux Φ, which is the integral of magnetic field over an area, are the weber (Wb) in the SI and the maxwell (Mx) in the cgs system. The conversion factor is 108, since flux is the integral of field over an area, area
