The Very Light Car
The Very Light Car prototype The Very Light Car (VLC) is a prototype design for 2- and 4-passenger automobiles emphasizing low weight and overall efficiency. It was originally developed by the Edison2 team for the Automotive X Prize competition. Two such 4-passenger cars were the only qualifiers in the finals of the "mainstream" division of the competition, and one of them won the 2010 division prize of $5 million with a competition fuel economy of 102.5 MPGe. The design emphasizes mainstream rather than exotic materials, extreme low weight (less than 450 kg (1000 lbs)) and very low aerodynamic drag ( coefficient of drag <0.16). Significant design innovations include in-wheel suspension and safety design derived from endurance auto racing. Edison2 team Edison2 was founded by Oliver Kuttner, a |

''The'' is a grammatical Article (grammar), article in English language, English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the Most common words in English, most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a con ...

Fuel Economy In Automobiles
The fuel economy of an automobile relates to the distance traveled by a vehicle and the amount of fuel consumed. Consumption can be expressed in terms of the volume of fuel to travel a distance, or the distance traveled per unit volume of fuel consumed. Since fuel consumption of vehicles is a significant factor in air pollution, and since the importation of motor fuel can be a large part of a nation's foreign trade, many countries impose requirements for fuel economy. Different methods are used to approximate the actual performance of the vehicle. The energy in fuel is required to overcome various losses ( wind resistance, tire drag, and others) encountered while propelling the vehicle, and in providing power to vehicle systems such as ignition or air conditioning. Various strategies can be employed to reduce losses at each of the conversions between the chemical energy in the fuel and the kinetic energy of the vehicle. Driver behavior can affect fuel economy; maneuvers s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sustainable Transport
Sustainable transport is transportation sustainability, sustainable in terms of their social and Environmental issue, environmental impacts. Components for evaluating sustainability include the particular vehicles used; the source of energy; and the infrastructure used to accommodate the transport (Street, streets and roads, rail transport, railways, airway (aviation), airways, waterways and canals). Transportation sustainability is largely being measured by transportation system effectiveness and efficiency as well as the environmental impact, environmental and climate change, climate impacts of the system. Transport systems have significant impacts on the environment. In 2018, it contributed to around 20% of global Greenhouse gas emissions, CO2 emissions. Greenhouse gas emissions from transport are increasing at a faster rate than any other energy using sector. Road transport is also a major contributor to local air pollution and smog. Sustainable transport systems make a posit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Daily Progress
''The Daily Progress'' is a newspaper published in Charlottesville, Virginia, United States. History ''The Daily Progress'' has been published since September 14, 1892. The paper was founded by James Hubert Lindsay and his brother Frank Lindsay. The ''Progress'' was initially published six days a week; the first Sunday edition was printed in September 1968. Lindsay's family owned the paper for 78 years. On November 30, 1970, the family announced a sale to Worrell Newspapers of Bristol, Virginia, which took over on January 1, 1971. Worrell's founder and namesake, T. Eugene Worrell, owned about two dozen rural weekly newspapers and a few dailies, all with less circulation than the ''Daily Progress''. However, his papers were noted for their high quality, a major factor in the Lindsays' decision to sell to him. The ''Progress'' immediately became the group's flagship paper, and Worrell moved corporate headquarters to Charlottesville. In 1979, T. Eugene Worrell split his newspap ...

Progressive Insurance Automotive X PRIZE
The Progressive Insurance Automotive X Prize (PIAXP or AXP) was a set of competitions, programs and events, from the X Prize Foundation, to "inspire a new generation of super-efficient vehicles that help break America's addiction to oil and stem the effects of climate change." Progressive Insurance was the title sponsor of the prize, the centerpiece of which is the Competition Division, within which a 10-million-dollar purse was divided between the winners of three competitions. The essence of each competition was to design, build and race super-efficient vehicles that achieved 100 MPGe (2.35 liter/100 kilometer) efficiency, produced less than 200 grams/mile well-to-wheel CO2 equivalent emissions, and could be manufactured for the mass market. Within the Competition Division, there are two vehicle classes: Mainstream and Alternative. The mainstream class had a prize of $5 million. The alternate class had two separate prizes of $2.5 million, one for side-by-side s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynamometer
A dynamometer or "dyno" is a device for simultaneously measuring the torque and rotational speed ( RPM) of an engine, motor or other rotating prime mover so that its instantaneous power may be calculated, and usually displayed by the dynamometer itself as kW or bhp. In addition to being used to determine the torque or power characteristics of a machine under test, dynamometers are employed in a number of other roles. In standard emissions testing cycles such as those defined by the United States Environmental Protection Agency, dynamometers are used to provide simulated road loading of either the engine (using an engine dynamometer) or full powertrain (using a chassis dynamometer). Beyond simple power and torque measurements, dynamometers can be used as part of a testbed for a variety of engine development activities, such as the calibration of engine management controllers, detailed investigations into combustion behavior, and tribology. In the medical terminology, h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Energy Density
In physics, energy density is the quotient between the amount of energy stored in a given system or contained in a given region of space and the volume of the system or region considered. Often only the ''useful'' or extractable energy is measured. It is sometimes confused with stored energy per unit mass, which is called ''specific energy'' or . There are different types of energy stored, corresponding to a particular type of reaction. In order of the typical magnitude of the energy stored, examples of reactions are: Nuclear power, nuclear, Chemical energy, chemical (including Electrochemistry, electrochemical), electrical, pressure, Deformation (engineering), material deformation or in Electromagnetic field, electromagnetic fields. Nuclear reactions take place in stars and nuclear power plants, both of which derive energy from the binding energy of nuclei. Chemical reactions are used by organisms to derive energy from food and by automobiles from the combustion of gasoline. Liqu ...

MPGe
Miles per gallon gasoline equivalent (MPGe or MPGge) is a measure of the average distance traveled per unit of energy consumed. MPGe is used by the United States Environmental Protection Agency (EPA) to compare energy consumption of alternative fuel vehicles, plug-in electric vehicles and other advanced technology vehicles with the energy consumption of conventional internal combustion vehicles rated in miles per U.S. gallon. The unit of energy consumed is deemed to be 33.7 kilowatt-hours without regard to the efficiency of conversion of heat energy into electrical energy, also measured in kilowatt-hours (kWh). The equivalence of this unit to energy in a gallon of gasoline is true if and only if the heat engine, generating equipment, and power delivery to the car battery are 100% efficient. Actual heat engines differ vastly from this assumption. MPGe does not necessarily represent an equivalency in the operating costs between alternative fuel vehicles and the MPG rating of inte ...

Automobile
A car, or an automobile, is a motor vehicle with wheels. Most definitions of cars state that they run primarily on roads, Car seat, seat one to eight people, have four wheels, and mainly transport private transport#Personal transport, people rather than cargo. There are around one billion cars in use worldwide. The French inventor Nicolas-Joseph Cugnot built the first steam-powered road vehicle in 1769, while the Swiss inventor François Isaac de Rivaz designed and constructed the first internal combustion-powered automobile in 1808. The modern car—a practical, marketable automobile for everyday use—was invented in 1886, when the German inventor Carl Benz patented his Benz Patent-Motorwagen. Commercial cars became widely available during the 20th century. The 1901 Oldsmobile Curved Dash and the 1908 Ford Model T, both American cars, are widely considered the first mass-produced and mass-affordable cars, respectively. Cars were rapidly adopted in the US, where they replac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
