Objects can transfer heat to their surroundings using light, but that method of heat exchange has always been thought to be very weak compared with conduction and convection. Now, in collaborative research among researchers at Columbia, Cornell, and Stanford, they discovered that we just weren’t doing it right. Their conclusion: light could become the most dominant form of heat exchange between objects.
In research described in the journal Nature Nanotechnology, the scientists discovered that when two objects are really close together, heat transfer via radiation is 100 times stronger than had been predicted. [Read More…]
