Polyphase wireless power transfer system achieves 270-kilowatt charge, s...
It’s common knowledge that driving aggressively can dent gas mileage, but it’s difficult to determine exactly how much gas drivers waste. A new study by researchers at the Department of Energy’s Oak Ridge National Laboratory has quantified the impact speeding and slamming on the brakes has on fuel economy and consumption. They found that aggressive behavior behind the wheel can lower gas mileage in light-duty vehicles by about 10 to 40 percent in stop-and-go traffic and roughly 15 to 30 percent at highway speeds. This can equate to losing about $0.25 to $1 per gallon.
While serving in Kandahar, Afghanistan, U.S. Navy construction mechanic Matthew Sallas may not have imagined where his experience would take him next. But researchers at Oak Ridge National Laboratory certainly had the future in mind as they were creating programs to train men and wome...
Scientists at Oak Ridge National Laboratory are using the precision of an electron beam to instantly adhere cathode coatings for lithium-ion batteries—a leap in efficiency that saves energy, reduces production and capital costs, and eliminates the use of toxic solvents.
Oak Ridge National Laboratory has successfully developed and tested a novel sand casting technique to quickly design complex patterns to fabricate components for industry partner Emrgy Hydro, makers of hydropower devices designed to generate electricity from slow or shallow water flo...
Advanced manufacturing will benefit from additive manufacturing techniques as demonstrated by a team led by Michael Kirka of Oak Ridge National Laboratory.
A 3D printed trim-and-drill tool, developed by researchers at the Department of Energy’s Oak Ridge National Laboratory to be evaluated at The Boeing Company, has received the title of largest solid 3D printed item by Guinness World Records. ORNL printed the...
A 20-kilowatt wireless charging system demonstrated at the Department of Energy’s Oak Ridge National Laboratory has achieved 90 percent efficiency at three times the rate of the plug-in systems commonly used for electric vehicles today. This ability can help acc...
A research demonstration unveiled today at the Department of Energy’s Oak Ridge National Laboratory combines clean energy technologies into a 3D-printed building and vehicle to showcase a new approach to energy use, storage and consumption. The Additive Manufactur...
When it’s up and running, the ITER fusion reactor will be very big and very hot, with more than 800 cubic meters of hydrogen plasma reaching 170 million degrees centigrade. The systems that fuel and control it, on the other hand, will be small and very cold. Pellets of frozen gas will be shot int...
The position of the University of Tennessee, Knoxville, and Oak Ridge National Laboratory as leaders in the manufacturing revolution has taken another bold step forward with the hiring of Uday Vaidya as the Governor's Chair in Advanced Composites Manufacturing.
