Hybrid vehicles more fuel efficient in India, China than in US
What makes cities in India and China so frustrating to drive in—heavy traffic, aggressive driving style, few freeways—makes them ideal for saving fuel with hybrid vehicles, according to new research by ...
Combination of three propulsion technologies brings maritime fuel savings
According to the TRIPOD research project coordinated by VTT Technical Research Centre of Finland lower fuel consumption and emissions are expected for an innovative propulsion system to be used as a promising alternative ...
Bio-electrochemical systems: Electricity generators of the future?
Billions of euros are spent treating trillions of litres of wastewater every year, consuming substantial amounts of energy. However, this wastewater could act as a renewable resource, saving significant quantities ...
New steering tech for heavy equipment saves fuel, ups efficiency
Researchers at Purdue University have shown how to reduce fuel consumption while improving the efficiency of hydraulic steering systems in heavy construction equipment.
Engineers gain insight into turbulence formation and evolution in fluids
in the patterns that natural gas makes as it swirls through a transcontinental pipeline or in the drag that occurs as a plane soars through the sky. Reducing such turbulence on say, an airplane wing, would ...
Drivers can easily save $130 a year without big performance concessions, researcher says
Drivers can make fuel savings of as much as 12% by shifting up to a higher gear sooner, without having the feeling that they're sacrifcing too much performance. That's the finding of a graduation project ...
Intelligent control for performance: Reducing drag, saving fuel
(Phys.org)—NASA Dryden's versatile F/A-18 Full Scale Advanced Systems Testbed (FAST) aircraft recently completed a series of flights that explored reducing fuel consumption during cruise flight conditions ...
Water footprint could tip scale for sustainable, emission-reducing energy options
Green energy won't be sustainable if it uses too much blue. Low-carbon energy options that increase water consumption could be swapping one problem for another.
Ultrasound can now monitor the health of your car engine
A system that uses ultrasound technology to look inside car engines could lead to more efficient engines – and huge fuel savings for motorists.
Light beams offer bright future for lighter-weight cars
(Phys.org)—Beams of light could one day replace the jumble of wires under a car bonnet, leading to lighter-weight and more fuel-efficient vehicles.
MASSIVE advances in aerodynamics
Engineers are closer to understanding, and therefore manipulating, invisible aerodynamic drag forces, that cause an estimated 50 per cent of transportation fuel to be lost before we can use it.
New California rules require cleaner cars
California, long a national leader in cutting auto pollution, pushed the envelope further Friday as state regulators approved rules to cut greenhouse gas emissions from cars and put significantly more pollution-free vehicles ...
White fish from the North Sea is equally climate friendly as farmed fish
The environmental impact of plaice and cod caught wild in the North Sea is similar to that of imported farmed fish like salmon, tilapia and pangasius. This was the conclusion arrived at by LEI, part of Wageningen ...
Detroit unsure over the future of green cars
The US auto industry remains unsold over the future of "green cars" such as electrics and hybrids, as carmakers struggle with the first steps in a market most agree shows promise over the long term.
