An article published in the October 27, 1969 issue of Design News indicated that a charged air spray could effectively cool hot surfaces. The technology has potential for application in the aviation and aerospace industries, as even in rarefied atmospheres, air friction can heat vehicle surfaces to temperatures in the thousands of degrees.
