n clear English, 66 illustrations and a minimum of math, this booklet details the peculiar radio technology of Nikola Tesla. Early elemental radio devices like Tesla's are fascinating and worthy of study because they remind us that powerful radio technologies can be simple and accessible. Modern radio took a lot from Tesla, but what did it ignore? 37 pages by George Trinkaus.

In Tesla's own words and illustrations, this is the inventor's final published statement on how radio could really work. Tesla says that 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 work places without wires? Can the unsightly and vulnerable grid come down? Tesla is convinced. 15 pages by George Trinkaus.
