Abstract : The report summarizes the results of a number of experiments conducted to support a program of fog clearing by the injection of electrical charges into the fog. Experiments were made to determine the charge transferred to water sprays which showed that contact charging mechanisms were as much as one million times as effective as induction charging mechanisms. The charge on soap film bubbles was measured and it was found that for a 2 inch bubble formed at 30 kV the charge was on the order of 1 micro Coulomb. Tests of fog clearing in an environmental chamber indicated fair results with water spray techniques and much better results with techniques by which charge is injected directly into the atmosphere (corona injection). Preliminary tests of corona injection into the atmosphere were carried out and showed that considerable charge attached to windborne particles. (Author)
