Bielefeld University physicists have found a way called spin currents to use the energy electronic devices such as computers generate as heat that mostly goes to waste. They apply the heat to generate magnetic signals known as ‘spin currents’. In the future, these signals could replace some of the electrical current in electronic components. In […]

University of Houston researchers are reporting that they have demonstrated a step forward in converting waste heat – from industrial smokestacks, power generating plants or even automobile tailpipes – into electricity. With energy conservation expected to play a growing role in managing global demand, materials and methods that make better use of existing sources of […]

Many phenomena in physics, though well-known, are not necessarily widely understood as is the case with thermoelectricity. Thermoelectricity is the phenomena that harnesses waste heat by coupling heat flux to build an electric current. Understanding such phenomena is important in order to leave the door open for discovering novel manifestations of them. Even today physicists […]

Northwestern University (NU) scientists have discovered a surprising material that is the best in the world at converting waste heat to useful electricity. An interdisciplinary team led by inorganic chemist Mercouri G. Kanatzidis found the crystal form of the chemical compound tin selenide conducts heat so poorly through its lattice structure that it is the […]

A team of Michigan State University researchers have developed a new thermoelectric material based on natural minerals known as tetrahedrites, the most widespread sulfosalts on Earth. So where are these tetrahedrites?  They’re found pretty much anywhere there is dirt, common ordinary dirt. The researchers, led by Donald Morelli, a professor of chemical engineering and materials […]
