better-functioning cities, for example. These forces are driving the demand for renewable power and smart transport systems to ease congestion. Technological answers include an increase in energy storage capacity, which will improve the range of electric vehicles and smooth out the supply of renewable power amid weather changes. More generally, smart products will bring digital intelligence to new places, as sensor-equipped machines become increasingly autonomous thanks to decision-making software

recharge pour batterie dans la ville mais aussi trop de risque de vandalisme ( par exemple sur le câble de rechargement). Économie Projets des transports électriques Des voitures et des bus électriques sans batteries (OLEV, pour OnLine electric vehicle) ont été testés en Corée en 2009. Leur moteur est alimenté par induction à partir d'une «voie magnétique» alimentée par un réseau de câbles enfouis à quelques centimètres sous la surface du sol. En juillet 2009, le prototype de bus fonctionnait

sizable portion of minerals. Since the available emissions data are simply stated in terms of PM mass, the best one can do is distinguish different typical PM compositions according to their source. ExternE treats power plant emissions as PM10 and vehicle emissions as PM2.5. In terms of the above equations one can summarize the assumptions of ExternE 1998 and 2000 for the health impact ∆I due to a concentration increment ∆ci as for the ExternE reports of 1998 ∆I = sPM10 ∆cPMpower + sPM2.5 ∆cPMtrans

Avant de nous intéresser aux autres composantes techniques, penchons-nous donc sur le fonctionnement de celui-ci. 1 2 Source : Batteries for Electric Vehicles (voir Bibliographie) Du nom de son inventeur -4- Travail de maturité „La voiture électrique, comme alternative réaliste à la voiture à essence“ Le moteur à combustion Ces moteurs sont aussi appelés « moteurs thermiques », car ils transforment

Their designs are based on scaling from adults, but children have unique biomechanical properties and are not just small adults. This project seeks to understand how the new child crash-test dummies perform in simulated

v=cqxlGMIWFbwTexte 1 Many people think that inspirations such as the electric light bulb come to the inventor in a sudden flash, but this was not the way it happened for Thomas Edison. As part of his research, Edison often went to expositions where new inventions were displayed. In 1878, he went to an exhibition where an invention called the arc lamp was being shown. This was a simple but inefficient invention in which a strong electric current was brought in from a strong wire to a thin copper wire

air comprimé tant sur le plan énergétique qu’écologique. * Une autre étude a elle été menée par une équipe de chercheurs chinois de l’université de Zhejiang (voir le texte en annexe) Cet article intitulé « Practicality study on air-powered vehicle » (Etude d’aspect pratique sur véhicules pneumatiques), publié dans la revue scientifique « Frontiers of Energy and Power Engineering in China » en 2008  a été élaboré par deux universitaires chinois LIU Lin, YU Xiaoli. Il s’agit d’une étude portant

This method produces sound by driving the piezoelectric diaphragm with electric signals supplied from an external oscillating circuit such as a multivibrator. Using this method, the piezoelectric buzzer can work as a speaker. In this method, a mechanical oscillation Qm of the piezoelectric diaphragm is damped properly to provide a wider frequency band of the sound pressure. This is applied to a switching sounds of home electric appliances, key-in sounds of OA equipment, alarm sounds of digital watches

tightening, small cars are selling well. City and subcompact cars both expanded their shares of the European market last year. Fiat is trying to position itself as a leader in low-emission cars as European lawmakers push manufacturers to cut their vehicles’ carbon dioxide emissions by a quarter by 2012. Fiat says the 500 will be compliant with Euro 5 emissions limits from its launch, two years before the standards come into force. The new Cinquecento will combine “emotional appeal with rational

generating company placed in the Northwest of the Argentine Republic. It was acquired by a consortium composed of Duke Energy, the American company; the Spanish Iberdrola and the Argentine Comercial del Plata when the privatization process in the electric market began. This market became highly competitive and the results of the station were very compromised given the bulky debt the company had contracted years before with foreign investors. By the end of 1998, and realizing that the company lacked
