Near-zero-energy buildings blessing to owners, environment
An electricity meter that sometimes runs backwards is just one of the cool aspects of Department of Energy near-zero-energy homes.
While low or no electric bills are an obvious benefit, high energy efficiency homes and businesses also reduce the amount of electricity that needs to be generated, thus reducing pollution, said Jeff Christian of DOE’s Oak Ridge National Laboratory.
In Tennessee, air pollution is of special concern as the state ranked third behind Cal
Blackout prevention effort launched as anniversary looms
As the dog days of summer approach, the electrical grid feels the heat, but a new integrated data network may help the aging transmission system weather the season without another massive blackout like the one experienced over much of the Eastern United States and Canada last August.
The Eastern Interconnection Phasor Project will “go live” this summer providing the first real-time, system-wide data to utilities and transmission operators within the Eastern power grid.

H2i to showcase optoelectronic user-machine interface at Electronica
H2i Technologies of France is to present its new, innovative user-machine interface at the Electronica show to be held in Munich in the autumn. This cutting-edge, patented optoelectronic technology re-invents data-entry systems for industrial and medical equipment as well as consumer and household goods by making it possible for any surface to be fully interactive – thus leading designers and engineers to re-think the ergonomic and other features of the devices they make.
As the winner of
Free electron laser reaches 10 kW
The Free-Electron Laser (FEL), supported by the Office of Naval Research and located at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility, achieved 10 kilowatts of infrared laser light in late July, making it the most powerful tunable laser in the world. The recently upgraded laser’s new capabilities will enhance defense and manufacturing technologies, and support advanced studies of chemistry, physics, biology, and more.
“No other laser can provide the same be
A New Advance in Gallium Nitride Nanowires
A significant breakthrough in the development of the highly prized semiconductor gallium nitride as a building block for nanotechnology has been achieved by a team of scientists with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley.
For the first time ever, the researchers have been able control the direction in which a gallium nitride nanowire grows. Growth direction is critical to determining the
Alternative Fuel Technology Being Blocked by National Policy
Crude oil imported to the United States costs more than $100 billion per year. As these reserves become depleted, synthetic alternatives may provide the best opportunities to displace these imports with indigenous products, including ethanol from corn, bio-diesel from vegetable oils, and oil from coal. However, it has been difficult to bring this new alternative fuel technology to the United States. A new study by a University of Missouri-Columbia researcher found that by changing existing roadbloc
