I have wondered for a long time can we add or remove electrons to air molecules. Create charged fields to force them to move over a surface at high speed. I am thinking only the air in contact with the surface or a % to control the air in contact with the surface. I picture a surface covered by a nano circuite. I have just heard that some one has added then remove a electron from a gold atom so we can add and remove electrons. A charged atom can be controlled with charged fields. Air moving over a surface reduces pressure on that surface. I do know that no air craft as ben made with the barnewly effect but can we make one.
