"Theory of Wireless Power" by Eric Dollard (c. 1986) is a technical and historical examination of Nikola Tesla’s methods for transmitting electricity without wires, specifically through natural media rather than Hertzian space waves. The work critiques modern, purely mathematical approaches to physics, favoring instead the experimental methodologies developed by Tesla, Maxwell, and Larmor. The text is designed to guide the understanding of how to engineer wireless power systems based on these longitudinal principles.
