New solar energy conversion process could revamp solar power production
Stanford engineers have figured out how to simultaneously use the light and heat of the sun to generate electricity in a way that could make solar power production more than twice as efficient as existing ...
Atoms at negative absolute temperature: The hottest systems in the world
(Phys.org)—In cold regions on earth, negative temperatures on the Fahrenheit or Celsius scale can often occur in winter; in physics, however, they were so far impossible. On the absolute temperature scale ...
Ancient effect harnessed to produce electricity from waste heat
A phenomenon first observed by an ancient Greek philosopher 2,300 years ago has become the basis for a new device designed to harvest the enormous amounts of energy wasted as heat each year to produce electricity. ...
Gemasolar solar thermal power plant supplies power for 24 hours straight
Graphene battery demonstrated to power an LED
The sun is a star when it comes to sustainable energy
At a national scientific meeting last week where biofuels - principally ethanol - were uniformly trashed as an environmental train wreck, one bright, carbon-free light gleamed in our energy future: the sun.
Cantilever bends repeatedly under light exposure for continuous energy generation
Controlling the interaction between light and matter
Pyroelectric nanogenerator charges Li-ion battery with harvested energy
Drinking water from air humidity
Cracks permeate the dried-out desert ground, the landscape bears testimony to the lack of water. But even here, where there are no lakes, rivers or groundwater, considerable quantities of water are stored ...
First stars in universe were not alone
The first stars in the universe were not as solitary as previously thought. In fact, they could have formed alongside numerous companions when the gas disks that surrounded them broke up during formation, ...
Ancient microbes discovered in bitter-cold Antarctic brine
Where there's water there's life – even in brine beneath 60 feet of Antarctic ice, in permanent darkness and subzero temperatures.
Sound could save circuits: Researchers theorize acoustic waves may cool microelectronics
(PhysOrg.com) -- "Hot sounds" has one meaning to music fans and another to physicists. Count a team of researchers at Rice University among the latter, as they've discovered that acoustic waves traveling along ...
