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.
Researchers have coated glass fibers with a new "thermoelectric"
material they developed. When thermoelectric materials are heated on one
side electrons flow to the cooler side, generating an electrical
Coated fibers also could be used to create a solid-state cooling
technology that does not require compressors and chemical refrigerants.
The fibers might be woven into a fabric to make cooling garments.
The glass fibers are dipped in a solution containing nanocrystals of
lead telluride and then exposed to heat in a process called annealing to
fuse the crystals together.
