CPU Cooling With Micro-Pumps
 

The prototype chip contains numerous water-filled micro-channels, grooves about 100 microns wide, or about the width of a human hair. The channels are covered with a series of hundreds of electrodes, electronic devices that receive varying voltage pulses in such a way that a traveling electric field is created in each channel. The traveling field creates ions, or electrically charged atoms and molecules, which are dragged along by the moving field.

and that's special because...?

My kids and one son in law graduated from Purdue Engineering School:)

that's nice :)
