Transportation—Going with the flow

November 1, 2018

November 1, 2018 — Self-driving cars promise to keep traffic moving smoothly and reduce fuel usage, but proving those advantages has been a challenge with so few connected and automated vehicles, or CAVs, currently on the road.

Cybersecurity – Guarding autonomous vehicles

October 5, 2017

October 5, 2017 – A new Oak Ridge National Laboratory-developed method promises to protect connected and autonomous vehicles from possible network intrusion. Researchers built a prototype plug-in device designed to alert drivers of vehicle cyberattacks.

Sensible driving saves more gas than drivers think

September 28, 2017

September 28, 2017 –  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.

Batteries – Quick coatings

April 3, 2017

April 3, 2017 - 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 researcher Tim Burress works with a prototype motor that generates 75 percent more power than comparable commercial motors without the use of rare earth materials.
