00:00 - In 1905 Nikola Tesla filed a visionary patent, US PAT, 723,188, describing a network of underground
00:09 - resonant coils that could beam electricity to moving vehicles. The concept is more than a footnote,
00:20 - Formally, the system comprises three intertwined components. First, a modular roadway embed with
00:26 - copper wound, toroidal primary coils insulated beneath a stone-like surface. Second, the vehicle,
00:32 - an elegant four-wheeled carriage with a polished mahogany body, articulated headlamps, and a promin
00:42 - resonant frequency. Finally, a central turbine-driven generator supplies a high-frequency alternatin
