US power grid costs rise, but service slips
America's power grid is like an old car. It gets the job done, even if its performance is slipping. But the repair bills go up every year and experts say only a major overhaul will reverse its decline.
Fully renewable electricity could be competitive
(Phys.org) —A carbon price of between $50 and $100 per tonne of carbon dioxide would make coal-fired and gas-fired power less economical than renewable electricity, a UNSW study shows.
Science fiction-style sabotage a fear in new hacks
When a computer attack hobbled Iran's unfinished nuclear power plant last year, it was assumed to be a military-grade strike, the handiwork of elite hacking professionals with nation-state backing.
A big leap toward lowering the power consumption of microprocessors
The first systematic power profiles of microprocessors could help lower the energy consumption of both small cell phones and giant data centers, report computer science professors from The University of Texas ...
Computer simulations for multiscale systems can be faster, better, more reliable
University of Oregon scientists have found a way to correctly reproduce not only the structure but also important thermodynamic quantities such as pressure and compressibility of a large, multiscale system at variable levels ...
Sunflowers inspire more efficient solar power system
(Phys.org) -- A field of young sunflowers will slowly rotate from east to west during the course of a sunny day, each leaf seeking out as much sunlight as possible as the sun moves across the sky through ...
Mobile LIDAR technology expanding rapidly
(Phys.org) —Imagine driving down a road a few times and obtaining in an hour more data about the surrounding landscape than a crew of surveyors could obtain in months.
Quadcopter piloted by a smartphone
The quadcopter, which was developed at TU Vienna, can negotiate its way through a room completely on its own. It does not need any human interference, and in contrast to other models, it is not assisted by ...
Chunky mobile devices? Soft graphene could help you downsize
Assuming you are geeky enough to open up any mobile device on the market – a phone, tablet or laptop – the most glaringly obvious component of the device is the battery: it generally consumes up to (if ...
Flame cyber virus linked to more malware: report
The Flame virus believed to be part of a cyberwarfare effort against Iran was developed as early as 2006 and is linked to at least three other malware programs, a new analysis said Monday.
How the alphabet of data processing is growing: Research team generates flying 'qubits'
The alphabet of data processing could include more elements than the "0" and "1" in future. An international research team has achieved a new kind of bit with single electrons, called quantum bits, or qubits. ...
Researchers capture wasted heat, use it to power devices
(Phys.org) —Imagine how much you could save on your electricity bill if you could use the excess heat your computer generates to actually power the machine. Researchers at the UCLA Henry Samueli School ...
