Future Car Technologies ... With rising gas prices, the future of the automobile is now leaning towards fuel efficiency, energy-savers, hybrid vehicles, battery electric vehicles, and fuel-cell vehicles... A variety of alternative fuel vehicles have been proposed or sold, including electric cars, hydrogen cars, compressed-air cars and liquid nitrogen cars...
Uranium Nitride ... Uranium mononitride was used as driver fuel for two core loads of the sodium cooled BR-10 reactor in Russia... The property which makes uranium mononitride highly attractive as a nuclear fuel is the combination of a high melting temperature with high thermal conductivity... Increased thermal conductivity results in lower thermal gradients between inner and outer sections of the fuel, potentially allowing for higher operating temperatures and reducing macroscopic restructuring of the fuel, which limits fuel lifetime...
Biofuels By Region ... A senior member of the House Energy and Commerce Committee, Congressman Fred Upton introduced legislation to use at least E10 fuel by 2012 in all cars in the USA... Federal subsidies alone cost $7 billion a year (equal to around $1.90 a gallon)." General Motors is starting a project to produce E85 fuel from cellulose ethanol for a projected cost of $1 a gallon... GM has over 4 million E85 cars on the road now, and by 2012 half of the production cars for the US will be capable of running on E85 fuel...
Biodiesel ... Biodiesel is meant to be used in standard diesel engines and is thus distinct from the vegetable and waste oils used to fuel converted diesel engines... Blends Blends of biodiesel and conventional hydrocarbon-based diesel are products most commonly distributed for use in the retail diesel fuel marketplace... Much of the world uses a system known as the "B" factor to state the amount of biodiesel in any fuel mix: 100% biodiesel is referred to as B100, while 20% biodiesel, 80% petrodiesel is labeled B20 5% biodiesel, 95% petrodiesel is labeled B5 2% biodiesel, 98% petrodiesel is labeled B2...
Economics Of Automobile Usage ... One general benefit is availability of use which, when coupled with public support via infrastructure (such as roads or fuel stations), can allow highly flexible movement and transportation...
Vegetable Oil Refining ... Refined diesel can be produced that is chemically identical to diesel fuel and does not have the problems specific to transesterified biodiesel... Petrobras planned to use 256 megalitres (1,610,000 bbl) of vegetable oils in the production of H-Bio fuel in 2007...
Vegetable Oil Fuel ... In the 1990s Bougainville conflict, islanders cut off from oil supplies due to a blockade used coconut oil to fuel their vehicles... Application and usability While engineers and enthusiasts have been experimenting with using vegetable oils as fuel for a diesel engine since at least 1900, it is only recently that the necessary fuel properties and engine parameters for reliable operation have become apparent... Modified fuel systems Most diesel car engines are suitable for the use of SVO, also commonly called pure plant oil (PPO), with suitable modifications...
Nuclear Fuel ... The actions of mining, refining, purifying, using, and ultimately disposing of nuclear fuel together make up the nuclear fuel cycle...
Biofuel ... Ethanol can be used as a fuel for vehicles in its pure form, but it is usually used as a gasoline additive to increase octane and improve vehicle emissions... Current plant design does not provide for converting the lignin portion of plant raw materials to fuel components by fermentation... Biodiesel can be used as a fuel for vehicles in its pure form, but it is usually used as a diesel additive to reduce levels of particulates, carbon monoxide, and hydrocarbons from diesel-powered vehicles...
Attribution Of Recent Climate Change ... Attribution of recent change to anthropogenic forcing is based on the following facts: The observed change is not consistent with natural variability. Known natural forcings would, if anything, be negative over this period...
Road Traffic Safety ... The standard measures used in assessing road safety interventions are fatalities and Killed or Seriously Injured (KSI) rates, usually per billion (109) passenger kilometres. Countries caught in the old road safety paradigm, replace KSI rates with crash rates - for example, crashes per million vehicle miles...
History Of The Automobile ... The first automobile patent in the United States was granted to Oliver Evans in 1789. 19th century Among other efforts, in 1815, a professor at Prague Polytechnich, Josef Bozek, built an oil-fired steam car...
Automobile ... Around the world, there were about 806 million cars and light trucks on the road in 2007; the engines of these burn over a billion cubic meters (260 billion US gallons) of petrol/gasoline and diesel fuel yearly...
Fuel ... Commonly, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived entirely from biological sources, such as tar sands... Fission The most common type of nuclear fuel used by humans is heavy fissile elements that can be made to undergo nuclear fission chain reactions in a nuclear fission reactor; nuclear fuel can refer to the material or to physical objects (for example fuel bundles composed of fuel rods) composed of the fuel material, perhaps mixed with structural, neutron moderating, or neutron reflecting materials... The most common fissile nuclear fuels are 235U and 239Pu, and the actions of mining, refining, purifying, using, and ultimately disposing of these elements together make up the nuclear fuel cycle, which is important for its relevance to nuclear power generation and nuclear weapons...
Automobile Safety ... Improvements in roadway and automobile designs have steadily reduced injury and death rates in all first world countries. Nevertheless, auto collisions are the leading cause of injury-related deaths, an estimated total of 1.2 million in 2004, or 25% of the total from all causes...
Uranium Carbide ... Like uranium dioxide and some other uranium compounds, uranium carbide can be used as a nuclear fuel for nuclear reactors, usually in the form of pellets or tablets...
