Scientists: Strong solar storm heading to Earth (Update)
A strong solar flare is blasting its way to Earth, but the worst of its power looks like it will barely skim above the planet and not cause many problems.
Greater capacity for batteries makes smaller devices
In a joint project, scientists optimized the electrical power of capacitors which will store and release energy charges.
Changing temperature powers sensors in hard-to-reach places
A centuries-old clock built for a king is the inspiration for a group of computer scientists and electrical engineers who hope to harvest power from the air.
Experiment makes energy savings a game
Let's face it: We're energy hogs. We want more light, we flip a switch. If we're hot, we crank up the AC, without a second thought on the power grid strain. It's what economists call inelastic demand – the resource is widely ...
Study investigates power generation from the meeting of river water and seawater
Where the river meets the sea, there is the potential to harness a significant amount of renewable energy, according to a team of mechanical engineers at MIT.
New super waterproof surfaces cause water to bounce like a ball
(Phys.org) —In a basement lab on BYU's campus, mechanical engineering professor Julie Crockett analyzes water as it bounces like a ball and rolls down a ramp.
University of California signs major solar deal
The University of California says it has made one of the largest ever solar-energy purchases by a university system in the United States.
Germany sets record for peak energy use – 50 percent comes from solar (Update)
Ordinary materials, fantastic opportunities
For Michael Demkowicz, some of the greatest scientific mysteries and major engineering opportunities lie in everyday materials. "Structural materials are sometimes seen as low-tech," he says. "Who thinks ...
Engineers invent a way to beam power to medical chips deep inside the body
A Stanford electrical engineer has invented a way to wirelessly transfer power deep inside the body, and then use this power to run tiny electronic medical devices such as pacemakers, nerve stimulators, or ...
Improved supercapacitors for super batteries, electric vehicles
Researchers at the University of California, Riverside have developed a novel nanometer scale ruthenium oxide anchored nanocarbon graphene foam architecture that improves the performance of supercapacitors, ...
Power arm band for wearables harvests body heat
Switchable material could harness the power of the sun—even when it's not shining
It's an obvious truism, but one that may soon be outdated: The problem with solar power is that sometimes the sun doesn't shine.
New graphene framework bridges gap between traditional capacitors, batteries
(Phys.org) —Researchers at the California NanoSystems Institute (CNSI) at UCLA have set the stage for a watershed in mobile energy storage by using a special graphene material to significantly boost the ...
