Solar-powered process could decrease carbon dioxide to pre-industrial levels in 10 years
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.
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 ...
Gemasolar solar thermal power plant supplies power for 24 hours straight
Ivanpah solar plant in California starts energy feed to grid
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 ...
Graphene battery demonstrated to power an LED
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. ...
Can a car engine be built out of a single particle?
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.
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, ...
Solar-thermal flat-panels that generate electric power
(PhysOrg.com) -- High-performance nanotech materials arrayed on a flat panel platform demonstrated seven to eight times higher efficiency than previous solar thermoelectric generators, opening up solar-thermal ...
Pyroelectric nanogenerator charges Li-ion battery with harvested energy
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 ...
