By Nikola Tesla (1919), edited by Trinkaus. In Tesla's own words and in 20 illustrations, this is the inventor's final published statement on how radio, at the radical, really works. What is the true wireless? Tesla says the orthodox Hertzian radio we've been taught is a "fiction." He insists that the amount of energy that can be transmitted is "billions of times greater" than conventional radio would allow. Can we transmit electric power to our homes and workplaces without wires? Can the unsightly and fragile grid come down? Tesla says Yes. This article of 1919 has been completely reset and redesigned for clarity. Includes an introduction by Trinkaus, explanatory notes, and information sources. 21 illustrations.
