  • Patent number: 10535789
    Abstract: This disclosure presents the use of electrons as the ‘working fluid’ in conjunction with a solid nanomaterial that hinders electron coupling to the atomic lattice of the nanomaterial, i.e., they are out of equilibrium. The electrons can achieve very high effective temperatures with minimal heating of the solid lattice. These ‘hot’ electrons emit from the absorbing material, carrying both the light energy and energy acquired from the atomic lattice. Thus, the operation of this disclosure includes shining light on an object to make the object cool instead of heat. It is envisioned that one of ordinary skill in the art would find the operation quite counter-intuitive.
