Remarkableriots Posted July 27, 2023 Share Posted July 27, 2023 Better energy harvesting with 'law-breaking' device PHYS.ORG If you take an object and set it out in the sun, it will begin to warm up. This is because it is absorbing energy from the sun's rays and converting that energy to heat. If you leave that object outside, ... Quote "Our study shows that it is possible to break the equality of Kirchhoff's law of thermal radiation with a device placed in a moderate magnetic field. The device itself combines a material that has a strong magnetic-field response with a patterned structure that enhances absorption and emission in infrared wavelengths. What is particularly exciting is that we can observe the effect by simply heating the device above room-temperature and directly comparing the emissive efficiency to the absorptive efficiency."
