OPERATING A FLEET OF ELECTRIC TAXIS ´ ´ BERNAT GACIAS AND FREDERIC MEUNIER Abstract. The deployment of electric taxi fleets is highly desirable from a sustainable point of view. Nevertheless‚ the weak autonomy of this kind of vehicles requires a careful operation. The way of managing such a fleet and the question of locating charging terminals for the vehicles are addressed in this paper. Methods for dealing with these tasks are proposed and their efficiency is proved through simulations. 1. Introduction

Who Killed the Electric Car? Video Discussion Questions Summary: It begins with a solemn funeral�for a car. By the end of Chris Paine’s lively and informative documentary‚ the idea doesn’t seem quite so strange. As narrator Martin Sheen notes‚ "They were quiet and fast‚ produced no exhaust and ran without gasoline." Paine proceeds to show how this unique vehicle came into being and why General Motors ended up reclaiming its once-prized creation less than a decade later. He begins 100 years ago

THE RELATIONSHIP OF ELECTRIC FIELD INTENSITY AND ITS DISTANCE FROM THE CHARGED OPOINT PHYS-232 JIANSONG HE GROUP: Abstract This experiment was performed to find the electric field strength from different distance to the charged point. The field strength was determined statically‚ by measuring its electrical potential when subjected to loading‚ and dynamically‚ by measuring the electrical potential at different location on the conductive paper. The electrical potential was measured from three

production side emissions of electric cars with this graph. Here we see the higher amount of emissions per electric car‚ although this can naturally be compensated during the lower emissions during the life-cycle of this car. To note that in case the battery has to be replaced during the life-time of the vehicle‚ the amount will increase to 12‚5t of CO2 per car‚ so more than the double of a gasoline car. 2.2 Source of energy. Here we get to one of the biggest problems of electrics cars: the way we charge

structures 1. This drill contains an electric motor. The diagram below shows the main parts of an electric motor. The carbon contacts are made of graphite. Springs push the contacts against the copper ring. The contacts conduct electricity to the copper ring. The copper ring rotates rapidly but does not stick or become worn because the graphite is soft and slippery. Graphite has properties which are ideal for making the contacts in an electric motor. Explain‚ in terms of structure and

In 1996‚ one car stood out above the rest. With its zero emissions and sporty‚ sleek design‚ the General Motors EV-1 was unstoppable. This car ran entirely without gas or oil of any kind. It ran only on electric power which made it very eco-friendly. It was built to comply with California’s zero emissions vehicle mandate that stated if auto makers wanted to sell cars in California some of those cars would have to be no exhaust

In 1996‚ electric cars began to appear on roads all over California. They were quiet and fast‚ produced no exhaust and ran without gasoline........... Ten years later‚ these futuristic cars were almost completely gone." ’Who Killed the Electric Car’ is a documentary which unfolds a complex set of events around the development and demise of the modern electric car. The story stems from California from the early 1990s to 2006. Chris Paine‚ the film maker has woven together interviews and archival

HOW AN ELECTRIC GENERATOR WORKS Electrical generators by definition are devices that convert mechanical energy into electric energy. The mechanical energy in turn is produced from chemical or nuclear energy in various types of fuel‚ or obtained from renewable sources such as wind or falling water. Steam turbines‚ internal-combustion engines‚ gas combustion turbines‚ electric motors‚ water and wind turbines are the common methods to supply the mechanical energy for such devices. Generators

Everything has a trade-off and opportunity cost. Electric cars are no exception. The first thing that caught my attention was the mileage. In the article and video‚ Rick Peters’ electric car only goes 25 miles per hour. You cannot get very far with that‚ especially since the farthest you can go in it is 30 miles per charge. I drive a Toyota Camry‚ and I drive 9.2 miles every day to school. It takes me 12-15 minutes to drive to school. If you ignore the speed limit on the roads (it is 55 mph)‚ it
