(Phys.org)—A new study predicts that large-scale power plants based on thermoelectric effects, such as small temperature differences in ocean water, could generate electricity at a lower cost than photovoltaic power plants.
For his semester project in mechanical engineering, Eliott Guenat studied the best way to recuperate waste heat from a car's engine. The challenge is figuring out how to incorporate the heat exchangers micro-turbomachines.
