Although more than 92,000 dams populate the country, the vast majority — about 89,000 — do not generate electricity through hydropower.

Oak Ridge National Laboratory researchers developed and demonstrated algorithm-based controls for a hybrid electric bus that yielded up to 30% energy savings compared with existing controls.

Salting the gears

Researchers at Oak Ridge National Laboratory proved that a certain class of ionic liquids, when mixed with commercially available oils, can make gears run more efficiently with less noise and better durability.

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.

ORNL researcher Xiaobing Liu  works in the laboratory’s Building Technologies Research and Integration Center.

As a boy growing up in China, Xiaobing Liu knew all about Oak Ridge and the World War II Manhattan Project. He had no idea that he would one day work at DOE’s Oak Ridge National Laboratory, the Secret City’s successor. Liu is a lead researcher in geothermal heat pump (GHP) techn...

Photovoltaic spray paint could coat the windows and walls of the future if scientists are successful in developing low-cost, flexible solar cells based on organic polymers. Scientists at the Department of Energy’s Oak Ridge National Laboratory recently discovered an unanticipated factor in the performance of polymer-based solar devices that gives new insight on how these materials form and function.
