First published in 1919, this is Tesla's final published statement on how radio, at the radical, really works. Everything you know is wrong. Tesla says the orthodox Herzian radio theory 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 without wires? Can the unsightly and vulnerable grid come down? Tesla is convinced. Edited by George Trinkaus. Completely reset and redesigned. 21 illustrations
