Energy harvesting seeks to recycle waste heat and use it to generate power for electronic devices. Here, the authors report an energy harvesting device whereby a non-thermal Tomonaga-Luttinger liquid channels heat from an active device to a heat engine. They find that the quantum-dot heat engine in the non-thermal regime surpasses the Carnot efficiency.
