This effect, which the researchers call ‘paramagnon drag thermopower,’ is a local thermal perturbations of spins in a solid that can convert heat to energy even in a paramagnetic material – where spins weren’t thought to […]

A small team of Monash University researchers working under the Australian Research Council (ARC) Center of Excellence for Electromaterials Science (ACES) has developed an ionic liquid-based thermoelectric cell. Thermoelectric cell technology is based on harnessing the thermal energy from the difference in temperature between two surfaces and converting that energy into electricity. The Aussie’s breakthrough […]

A New Way to Harvest Heat

September 27, 2010 | 5 Comments

Catching the energy lost from waste heat has been on the wish list of engineers for as long energy has been understood.  Yet the functioning concept for replacing existing techniques that is both more efficient and economically competitive hasn’t arrived. Now University of Arizona physicists are announcing they have discovered a new way of harvesting […]
