Researchers at Purdue University in the U.S. have developed a new method of harvesting vast amounts of energy from waste heat. Using glass fibers dipped in a solution containing nanocrystals of lead telluride, the team led by Dr. Yue Wu is engineering a highly flexible thermoelectric system that generates electricity by gathering heat from water pipes and engine components.
