Could a laser send a spacecraft to Mars? That's a proposed mission from a group at McGill University, designed to meet a solicitation from NASA. The laser, a 10-meter wide array on Earth, would heat hydrogen plasma in a chamber ...
Spintronic devices, a class of architectures that can store or transfer information by leveraging the intrinsic spin of electrons, have been found to be highly promising, both in terms of speed and efficiency. So far, however, ...
(Phys.org) —Today when an electric vehicle is plugged into the grid, it's almost always in charge mode, meaning it consumes power. But it's also possible for an electric vehicle to operate in discharge mode, in which it ...
(Phys.org) —While previous research has shown that wind turbulence causes the power output of wind turbines to be intermittent, a new study has found that wind turbulence may have an even greater impact on power output ...
(Phys.org)—Although the LHC has often been called the largest machine in the world, that title may be more appropriately given to something much more familiar: power grids. Consisting of thousands of generators and substations ...
(Phys.org)—In order to meet increasing energy demands, power companies have the option of adding new power lines to the existing grid. But in a new study, researchers have found that, contrary to common intuition, adding ...
(Phys.org)—While most of today's electric vehicles rely on batteries to store energy, supercapacitors have enjoyed significant improvements that have made them serious competitors to batteries. Batteries traditionally have ...
(Phys.org)—For many years, researchers have strived to reach the goal of 10% efficiency for polymer-based organic photovoltaic (OPV) solar cells, a target widely considered to be the threshold for commercial applications. ...
(Phys.org) -- In an attempt to lower the cost of making flexible write-once-read-many (WORM) memory devices, a team of researchers from Finland has developed a fabrication process that can mass-print thousands of these memories ...
(PhysOrg.com) -- For the first time, researchers have demonstrated that an LED can emit more optical power than the electrical power it consumes. Although scientifically intriguing, the results won’t immediately result ...
