Purdue University researchers, in work funded by Intel are developing tiny "ionic wind engines" that when used in combination with a conventional computer fan, can enhance the fan's effectiveness by boosting airflow over the surface of a computer chip. The experimental ionic cooling device works by generating ions — or electrically charged atoms — using electrodes placed near one another, researchers said in a release. The device contained a positively charged wire, or anode, and negatively charged electrodes, called cathodes. The anode was positioned about 10 millimeters above the cathodes. When voltage was passed through the device, the negatively charged electrodes discharged electrons toward the positively charged anode. Along the way, the electrons collided with air molecules, producing positively charged ions, which were then attracted back toward the negatively charged electrodes, creating an "ionic wind," researchers stated. This breeze increased the airflow on the surface of the experimental chip. http://www.networkworld.com/community/node/18407"
