'Invisible' particles could enhance thermoelectric devices

Thermoelectric devices—which can either generate an electric current from a difference in temperature or use electricity to produce heating or cooling without moving parts—have been explored in the laboratory since the ...

Nanocrystal-coated fibers might reduce wasted energy

(Phys.org) -- Researchers are developing a technique that uses nanotechnology to harvest energy from hot pipes or engine components to potentially recover energy wasted in factories, power plants and cars.

Droughts boost emissions as hydropower dries up

When hydropower runs low in a drought, western states tend to ramp up power generation—and emissions—from fossil fuels. According to a new study from Stanford University, droughts caused about 10 percent of the average ...

Low-cost 'solar absorber' promising for future power plants

Researchers have shown how to modify commercially available silicon wafers into a structure that efficiently absorbs solar energy and withstands the high temperatures needed for "concentrated solar power" plants that might ...
