Arizona solar plant achieves six hours after sun goes down
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 ...
Researchers generate pressurised 'supercritical' steam, at the highest temperatures ever achieved using solar energy
(Phys.org) —Supercritical steam is a breakthrough for solar energy and means that one day the sun could be used to drive the most advanced power stations in the world, currently only driven by coal or gas.
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 ...
Ivanpah solar plant in California starts energy feed to grid
First direct observation of carbon dioxide's increasing greenhouse effect
Scientists have observed an increase in carbon dioxide's greenhouse effect at the Earth's surface for the first time. The researchers, led by scientists from the US Department of Energy's Lawrence Berkeley ...
Creating electricity with caged atoms
Clathrates are crystals consisting of tiny cages in which single atoms can be enclosed. These atoms significantly alter the material properties of the crystal. By trapping cerium atoms in a clathrate, scientists ...
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
Rainbow-catching waveguide could revolutionize energy technologies
(Phys.org) —By slowing and absorbing certain wavelengths of light, engineers open new possibilities in solar power, thermal energy recycling and stealth technology.
New thermocell could harvest 'waste heat'
(Phys.org) —Harvesting waste heat from power stations and even vehicle exhaust pipes could soon provide a valuable supply of electricity.
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.
