Consumption

The boat tail mounted on the rear of the test truck

European tests have shown that a boat tail – a tapering protrusion mounted on the rear of a truck – leads to fuel savings of 7.5 percent. The fuel savings, which also means a cut in emissions, were realized by the boat tail dramatically reducing the drag caused by the lower-pressure effect that occurs in the wake of a vehicle.  Read More

Samsung’s STORY Station drives cut standby power consumption by 95 percent

Samsung’s STORY Station drives will be the first 3.5-inch external hard drives to boast a standby power consumption of less than 1W. The typical standby power consumption of external hard drives is around 2.5W, so lowering that figure to 0.09W constitutes a reduction of more than 95 percent. The reduced standby power level easily meets requirements for the forthcoming European Union’s EuP (Energy Using Products) Directive for Standby Regulation, which is effective from January 2010.  Read More

The X-Ray Observatory set for launch after 2020 might be the spacecrafts to use femtosecon...

Theoretical work commissioned to the National Physical Laboratory (NPL) by the European Space Agency has recently concluded that lasers capable of generating extremely short pulses — known as "femtosecond comb lasers" — could be of great help in measuring the distance between two or more spacecraft to an accuracy of just a few microns, an essential component to formation flying space missions scheduled for the next decades.  Read More

The Vexia Econav 435 gives drivers recommendations on the most fuel-efficient way to reach...

As GPS navigation systems increase in popularity, the world’s fuel supplies simultaneously are in decline. However, the Vexia Econav 435 GPS is attempting to do its bit for the environment by offering a system that gives drivers information on the most economical route, which gear to use and when - even how firmly to accelerate. The manufacturers say the aim of the unit is to reduce drivers' fuel consumption by up to one third.  Read More

Can the Earth sustain 9 billion people? We'll find out in the next 50 years.

We're living in lucky times. Living standards - in the Western world, at least - are the highest in history. It's an era of relative peace and plenty that would amaze our ancestors. But it's not going to continue forever; we're already stretching many of our natural resources to their limits, and the world's population will jump from 6.5 billion to around 9 billion over the next 50 years. Get ready for a painful correction - here are four interconnected resources that are headed for a catastrophic squeeze within our lifetime.  Read More

The Fisker Karma PHEV during its hot lap at Mazda Raceway Laguna Seca.  Look for productio...

The Fisker Karma Plug-in Hybrid Electric Vehicle (PHEV) recently demonstrated how quick it is in two ways – it goes from 0-60mph in six seconds and from concept to public driving debut just 19 months after the company was formed. The 403hp prototype Karma PHEV almost silently attained a top speed of 100mph (using no gasoline) as it made its way around the Mazda Raceway Laguna Seca during the Rolex Monterey Historic Automobile Races.  Read More

At 25 mpg, an original Model T would still give you better fuel economy that most vehicles...

Gizmag is always on the lookout for alternative means of powering vehicles and saving precious fossil fuels. But, in truth, the vast majority of us still drive exclusively petrol-powered cars. And the even sadder truth, outlined in a new research from the University of Michigan, is that the average fuel efficiency of a US vehicle has improved only three miles per gallon since the days of the Ford Model T.  Read More

Hybrid! Hail a cab from Colin Paton and there's a good chance you'll get in a Toyota Prius...

Scottish council, West Lothian (near Edinburgh), has given the green light to a local cab company to run a fleet of Toyota Prius vehicles. The decision makes Calder Cabs the first cab company in Scotland to offer the hybrid cars after the council determined that the Prius could be licensed as a private hire vehicle.  Read More

The new Mazda3 incorporates fuel-saving technology for drivers who face the daily grind of...

One of the bug bears of driving in city traffic – apart from the time delays – is the often deplorable fuel consumption of stop-start driving. To help overcome this, the new Mazda3 2.0 Sport comes with iStop technology which pauses the engine (rather than stopping it), which the company says delivers increased fuel economy while reducing CO2 emissions.  Read More

The new study by researchers at the University of California looks beyond the exhaust pipe...

By looking at the environmental impact of passenger transport – whether it be trains, planes or automobiles – beyond the exhaust fumes spewing from its collective tail pipe, researchers in the United States have discovered a significant spike in energy use and greenhouse gas emissions. By taking into account transport support systems – which includes sourcing raw materials, manufacturing, as well as the construction and maintenance of infrastructure – researchers at the University of California hope to provide a more detailed view for transport planners and policy makers. And produce a better outcome for the environment.  Read More
