Using AI to Design More Efficient Heat Pumps
July 16, 2019 | Leave a Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… Ecole Polytechnique Fédérale de Lausanne (EPFL) researchers have developed a method that uses artificial intelligence to design next-generation heat-pump compressors. Their method can cut the pumps’ power requirement by around 25%. In Switzerland, 50 to 60% of new homes are equipped with heat pumps. These systems draw in thermal energy from the surrounding environment […]

University of Houston (UH) researchers have reported a major step forward in the search for new thermoelectric materials. The discovery offers a new explanation for asymmetrical thermoelectric performance. The promise of thermoelectric materials as a source of clean energy drives the search for materials that can efficiently produce substantial amounts of power from waste heat. […]

A New Thermoelectric Nanoantenna
May 21, 2019 | Leave a Comment
Collaborators of three labs in Mexico have demonstrated an innovative nanodevice for harvesting solar energy. The study paper has been published in the SPIE Journal of Nanophotonics. The paper, “Thermoelectric efficiency optimization of nanoantennas for solar energy harvesting,” reports that evolutive dipole nanoantennas (EDN) generate a thermoelectric voltage three times larger than the classic dipole […]

New Material Hunt For Thermoelectric Generation
May 15, 2019 | Leave a Comment
University of Texas at Austin’s Texas Advanced Computing Center has shown that a voltage can be generated by harnessing differences in spin populations on a metal contact attached to a ferromagnetic material through a mechanism known as the Spin Hall effect. The researchers used supercomputers to identify various forms of cobalt oxide combined with nickel […]

University of Zurich physicists have developed an amazingly simple device that allows heat to flow temporarily from a cold to a warm object without an external power supply. Intriguingly, the process initially appears to contradict the fundamental laws of physics. If you put a teapot of boiling water on the kitchen table, it will gradually […]
