Boosting the fuel efficiency of motor vehicles by “harvesting” the energy generated by their shock absorbers and feeding it back into batteries or electrical systems such as air conditioning has become a major goal in automotive engineering. Now, a University of Huddersfield researcher has made a breakthrough by designing a new system and constructing a
Reliable power, information overload, size and weight, and interpreting old-fashioned infantry hand signals top research priorities for digitizing the warfighter. The first recorded war took place between Sumer and Elam in Mesopotamia in 2700 BC, but archaeological evidence shows a history of violent mass conflict for more than 12,000 years, about the time humans began
Smart devices that wake up with voice commands have gained popularity in recent years, and now researchers at Georgia Institute of Technology have taken it one step farther: an always-on camera. Designed with a combination of low-power hardware and energy efficient image processing software, the always-on camera is capable of watching for specific types of
The Argonne National Laboratory’s Systems Assessment Group announced 2016 release of the suite of GREET (Greenhouse gases, Regulated Emissions, and Energy use in Transportation Model) models and associated documentation. GREET is a full life-cycle model that allows researchers and analysts to evaluate various vehicle and fuel combinations on a full fuel-cycle/vehicle-cycle basis. GREET 2016 provides
In the race towards miniaturization, a French-US team-mostly involving researchers from the CNRS, Université de Lille, Université de Nantes and Argonne National Laboratory (US) as part of the Research Network on Electrochemical Energy Storage (RS2E)1-has succeeded in improving the energy density of a rechargeable battery without increasing its size (limited to a few square millimeters
A detailed nano-mechanical study of mechanical degradation processes in silicon structures containing varying levels of lithium ions offers good news for researchers attempting to develop reliable next-generation rechargeable batteries using silicon-based electrodes. Anodes – the negative electrodes – based on silicon can theoretically store up to ten times more lithium ions than conventional graphite electrodes,
The Defining Challenge of Our Generation is Sustainable Energy and Manufacturing. Our mission is to identify innovators with ideas for energy- and science-based technologies that can have a significant impact on the lives of billions of people. We will provide these innovators with the laboratory tools, seed capital, and collaborators needed to grow their early-stage
Fabrics that can generate electricity from physical movement have been in the works for a few years. Now researchers at Georgia Institute of Technology have taken the next step, developing a fabric that can simultaneously harvest energy from both sunshine and motion. Combining two types of electricity generation into one textile paves the way for
Tokyo, April 25, 2016 – A thermoelectric (TE) device using cutting edge thermoelectric conversion technology has been created by a team comprising NEC Corporation, NEC TOKIN Corporation and Tohoku University. The new technology, known as the spin Seebeck effect, has conversion efficiency 10 times higher than the conventional method *3. Thermoelectric conversion technology that converts
Superconductivity is a hot phenomenon that occurs only at very cold temperatures. Finding ways to change that and make superconductivity practical at higher temperatures is a major goal for physicists and engineers. One possibility involves the metallic phase of hydrogen, theorized to be superconducting at ambient temperatures but yet to be achieved in practice. By
Army scientists are on the trail of new high-performing energetic materials. Scientists at the U.S. Army Research Laboratory recently synthesized a new material called bis-isoxazole tetranitrate, or BITN, with potential applications in propulsion and lethality. “BITN has a strong potential for improving insensitive munitions characteristics for gun and rocket propellants” said Dr. Jesse J. Sabatini,
