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.

[How does this compare to a Peltier device?

    Yes, unless the room is at absolute dark, as DannyB has pointed out. (Obviously).

    You gotta have pretty good night vision to go around hooking up LEDs and resisters in the dark, don't you?
