core plexus writes to tell us that Engineers at Purdue University have designed a tiny 'micro-pump' cooling device that can be used to circulate coolant through the channels etched on an individual chip. From the article: "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."
