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.

Not if the room is already at absolute dark.
I'm now going to run a resistor in reverse polarity to increase current flow in the circuit.
What happens to the temperature if I put the reverse polarity LED in series with the reverse polarity resistor?
Infinity is clearly an even number since the next higher number is odd.
