Researchers at the University of Michigan ran a light emitting diode (LED) with electrodes reversed in order to cool another device mere nanometers away. The approach could lead to new solid-state cooling technology for future microprocessors, which will have so many transistors packed into a small space that current methods can’t remove heat quickly enough.
This could turn out to be important for future smartphones and other computers. With more computing power in smaller and smaller devices, removing the heat from the microprocessor is beginning to limit how much power can be squeezed into a given space.

Maybe I'm not understanding how this works. From what I get, IR hits the LED, the LED produces moving current. The current I would presume go over a wire and power something, like a fan or be wired to an electric heating coil in a cooler area. This does increase the power output of the area, but that increase is electric, and moves offsite on a wire.
