Smart Roof Coating For A Warm Winter And Cool Summer
January 13, 2022 | Leave a Comment
Lawrence Berkeley National Laboratory scientists have developed an all-season smart-roof coating that keeps homes warm during the winter and cool during the summer. The coating works without consuming natural gas or electricity. Research findings point to a groundbreaking technology that outperforms commercial cool-roof systems in energy savings. The paper reporting the findings has been published […]

Improvement Found To Increase Electricity From Wasted Heat
October 27, 2021 | Leave a Comment
Tokyo Institute of Technology (TIT) scientists demonstrated that breaking open the trade-off problem between thermopower and conductivity improves thermoelectric performance. Energy consumption in developed countries has been rather wasteful. Nearly two-thirds of the total energy is typically discarded as “waste heat,” which ends up simply dumped into the atmosphere. Lately, finding a way to productively […]

Fibers In Clothes Can Make Electricity From Heat
September 15, 2021 | Leave a Comment
Researchers have found carbon nanotubes woven into thread-like fibers and sewn into fabrics become a thermoelectric generator. The invisibly small carbon nanotubes aligned fibers can turn heat from the sun or other sources into other forms of energy. The Rice University lab of physicist Junichiro Kono led an effort with scientists at Tokyo Metropolitan University […]

Heat To Energy New Thermoelectric Material Sets Record
August 4, 2021 | Leave a Comment
Northwestern University scientists have demonstrated a high-performing thermoelectric material in a practical form that can be used in device development. The material – purified tin selenide in polycrystalline form – outperforms the single-crystal form in converting heat to electricity, making it the most efficient thermoelectric system on record. A key application target of thermoelectric devices […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… Ohio State University researchers show in a new study that a single material, a layered crystal consisting of the elements rhenium and silicon, turns out to be the gold standard of transverse thermoelectric devices. Thermoelectric power generators that make electrical power from waste heat would be a useful tool to reduce greenhouse gas emissions […]
