Electrical Experimenter (07:11) March 1920

Hugo Gernsback, editor

"While working on a means for transmitting radio waves without material aerials, Mr. John Hettinger hit upon the idea of using ionized light beams as elevated conductors. It is a well-known fact that an ionized gas is a conductor; in fact, the conductivity of a gas is a measure of its ionization. Furthermore, it is possible to ionize a gas by means of a stream of ultraviolet rays. Working with these facts, Mr. Hettinger devised a means to utilize them for radio transmission."
