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.
Controlling thermal conductivities can improve energy storage
Controlling the flow of heat through materials is important for many technologies. While materials with high and low thermal conductivities are available, materials with variable and reversible thermal conductivities ...
Stronger black solar coating that retains original color and absorption properties
(Phys.org) —Solar thermal panels developed at EPFL are are dressed up in unique and patented new materials. Researchers created a stronger black coating that retains its original color and thereby its absorption ...
Fur and feathers keep animals warm by scattering light
In work that has major implications for improving the performance of building insulation, scientists at the University of Namur in Belgium and the University of Hassan I in Morocco have calculated that hairs ...
Thermoelectric bracelet: 'Cool' invention wins first place at MADMEC
Heating or cooling certain parts of your body—such as applying a warm towel to your forehead if you feel chilly—can help maintain your perceived thermal comfort.
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 ...
Clay key to high-temperature supercapacitors
Clay, an abundant and cheap natural material, is a key ingredient in a supercapacitor that can operate at very high temperatures, according to Rice University researchers who have developed such a device.
Rattling ions limit heat flow in materials used to reduce carbon emissions, study finds
A new study published today in the journal Nature Materialss has found a way to suppress the thermal conductivity in sodium cobaltate so that it can be used to harvest waste energy.
Bio-inspired design may lead to more energy efficient windows
University of Toronto Engineering professor Ben Hatton is turning to nature to find a way to cut down on the energy leaks from windows.
Lifelike cooling for sunbaked windows: Adaptable microfluidic circulatory system could cut air-conditioning costs
Sun-drenched rooms make for happy residents, but large glass windows also bring higher air-conditioning bills. Now a bioinspired microfluidic circulatory system for windows developed by researchers at the ...
Planetary 'runaway greenhouse' more easily triggered, research shows
(Phys.org) —It might be easier than previously thought for a planet to overheat into the scorchingly uninhabitable "runaway greenhouse" stage, according to new research by astronomers at the University of Washington and ...
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.
