Nikola Tesla's "The True Wireless" (a compilation of his writings and lectures, not a single authored book as commonly understood, but reflecting his core work) argues that wireless transmission of energy, particularly electrical power, is not only feasible but essential for global progress and the advancement of civilization. Tesla's central thesis is that the Earth itself can be utilized as a resonant conductor to transmit electrical power wirelessly and efficiently over vast distances, eliminating the need for physical wires.
The key ideas presented include the principles of resonance, harmonic oscillation, and the concept of the Earth as a single, unified electrical system. Tesla details his experiments with high-frequency currents and his vision of global communication and power distribution networks. Readers gain an understanding of his innovative approach to electricity, his belief in harnessing natural forces for human benefit, and his ambitious engineering dreams that laid the groundwork for future wireless technologies.

Key concepts
- Resonant Transformer Circuit (Tesla Coil) — A device designed to produce high-voltage, high-frequency alternating current electricity, crucial for his wireless transmission experiments.
- Earth Resonance — The theory that the Earth's ionosphere and its conductive core could act as a giant, tunable capacitor and conductor for transmitting electrical signals and power.
- Longitudinal Waves — Tesla's proposed type of electromagnetic wave that could propagate through a medium with greater efficiency than transverse waves, suitable for long-distance transmission.
- Global Wireless System — Tesla's vision for a worldwide network capable of transmitting both power and information wirelessly, transforming communication and industry.
