Advanced adsorption chiller uses nanomaterial to be up 50 percent more efficient
A new, energy-efficient air chilling system could keep troops on the front lines cool while using about half as much diesel as current systems. The system's decreased fuel consumption could also save lives ...
Improved thermoelectric materials with atomic layer deposition
Researchers at the Aalto University School of Chemical Technology have applied atomic layer deposition (ALD) technique to the synthesis of thermoelectric materials. Converting waste energy into electricity, ...
Savanna study highlights African fuelwood crisis
(Phys.org)—The dwindling reserves of fuelwood in Africa have been illuminated in a new study published today, which shows a bleak outlook for supplies across savannas in South Africa.

NASA's green aviation research throttles up into second gear
NASA has selected eight large-scale integrated technology demonstrations to advance aircraft concepts and technologies that will reduce the impact of aviation on the environment over the next 30 years, research efforts that ...
'Gently does it' drives you further in electric vehicles
Drivers of petrol and diesel cars are usually aware that driving at high speed, harsh acceleration and hard braking all contribute to lowering their fuel economy. Scientists can readily explain in terms of the thermodynamics ...
Cellphone, GPS data suggest new strategy for alleviating traffic tie-ups
Researchers from MIT and UC Berkeley tracked traffic in Boston and San Francisco with cell tower and GPS data and analyzed bottlenecks. Their computer analysis suggested a possible strategy for relieving ...
Paper waste used to make bricks
Researchers at the University of Jaen (Spain) have mixed waste from the paper industry with ceramic material used in the construction industry. The result is a brick that has low thermal conductivity meaning ...
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.
Nation needs marketing campaign to reduce vehicle fuel use, says new paper
(Phys.org)—A new paper from Rice University's Baker Institute for Public Policy proposes a national marketing campaign to better inform consumers about measures that they can take to decrease fuel use, particularly during ...
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.
Fuel economy remains at record high, emissions now at record low
Fuel economy of all new vehicles sold in the United States remains at its highest level ever, while emissions are at a record low, say researchers at the University of Michigan Transportation Research Institute.
Asia air pollution deaths to rise, environment group says
Air pollution in Asia, which already kills at least 800,000 people each year, will likely lead to even higher death rates as the region's air quality worsens, an environmental group warned Wednesday.
Eco campaigners bash Germany's gas-guzzling cars
Environmental campaigners have taken aim at famous German car brands like Porsche, Audi and BMW, criticising their high CO2 emissions as well as Germany's tax system they say promotes gas guzzlers.
