Some engineers at Purdue University have invented tiny "micro-pump" cooling device that can be used to circulate coolant throughout the channels etched on an individual chip. The prototype chip contains numerous water filled micro-channels, grooves that are about the width of a human hair. The channels are also covered with hundreds of electrodes that receive varying voltage pulses in such a way that a traveling electric field is created in each individual channel. The traveling field creates ions, or electrically charged atoms and molecules, which are dragged along by the moving field.
