Clean Cities coalitions around the nation displaced the equivalent of 375 million gallons of gasoline in 2006, according to a recent report from the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL). The amount of gasoline displaced in 2006 was 50 percent more than the 250 million gallons in 2005.
About 42% of fatal car accidents happen at night, according to the European Commission for the Automobile Industry. This figure is extremely worrying bearing in mind that there is about 60% less traffic during at night time.
For nearly 150 years, scientists have been puzzled by the bicycle. How on earth is it possible that a moving bicycle can, all by itself, be so stable?
Microsoft currently works on a system HUD, or “posting high head” intended for the cars. At least, it is what lets think a description deposited on the site of the American Office of the patents and the marks.
The HUD profits already from a long past behind him, since it equips the fighters with the whole world since the end of the Fifties.
Inspired by the efficient swimming motion of the bluegill sunfish, MIT researchers are building a mechanical fin that could one day propel robotic submarines.
Two graduate students at MIT's School of Architecture and Planning want to harvest the energy of human movement in urban settings, like commuters in a train station or fans at a concert. The so-called "Crowd Farm" would turn the mechanical energy of people walking or jumping into a source of electricity.
An automated way of allowing cars to drive much closer to each other in heavy moving traffic, so-called platooning, could cut congestion, save fuel and cut greenhouse gas emissions, according to new research.
NASA's Cassini spacecraft has revealed for the first time surface details of Saturn's moon Hyperion, including cup-like craters filled with hydrocarbons that may indicate more widespread presence in our solar system of basic chemicals necessary for life.
A market-based incentive program to reduce global warming emissions from new cars and trucks would cut pollution as much as 33 percent and provide up to $2,500 in lifetime fuel savings for drivers, according to a new study by the University of Michigan's Transportation Research Institute (UMTRI).
A Purdue University engineer has developed a method that uses an aluminum alloy to extract hydrogen from water for running fuel cells or internal combustion engines, and the technique could be used to replace gasoline. The method makes it unnecessary to store or transport hydrogen - two major challenges in creating a hydrogen economy.
Researchers have created the first computational model to track engine performance from one combustion cycle to the next for a new type of engine that could dramatically reduce oil consumption and the emission of global-warming pollutants.
As the demand for biofuels surges with over one billion people living without access to electricity, a new United Nations report released today cautions that the world’s energy needs must be met in a sustainable and environmentally sound manner.
China accounts for around 15% of the world’s total number of deaths from traffic accidents each year. Motor vehicle production has tripled since the 1990s and despite the availability of seat belts in almost all passenger cars in China and laws requiring restraint use, the habitual use of seat belts is low. With the human toll alone from road traffic injuries in China around 100,000 deaths per year, there is an urgency to implement such interventions in the major cities.
EU legislation to promote the uptake of biodiesel will not make any difference to global warming, and could potentially result in greater emissions of greenhouse gases than from conventional petroleum derived diesel. This is the conclusion of a new study reported today in Chemistry & Industry, the magazine of the SCI.
Ethanol is widely touted as an eco-friendly, clean-burning fuel. But if every vehicle in the United States ran on fuel made primarily from ethanol instead of pure gasoline, the number of respiratory-related deaths and hospitalizations would likely increase, according to a new study by Stanford University.
