Saturday Aug 14 • Session 8 (Morn) • Tesla’s ExtraOrdinary Concepts numbers are correct the resonate “Q-factor“ still Nikola Tesla’s has to be increased more to achieve a self running Electric Car standalone resonate system I know of two ways to increase the "Q" factor of Power Supply a resonate system. The first method is to increase the reactive component by adding a large (10x) --- 20 21 --- inductor in series with the motor impedance. I Michael Gamble built and documented a working “Series Resonate” There are numerous stories about Nikola Tesla’s demo model of this method and presented it at the fabled electric powered Pierce-Arrow car.

Tesla stated TeslaTech 2018 and 2019 both showed a large that his resonate systems ran near unity (99.8%) increased resonate efficiency (30% to 90%).

Tesla coil circuits were used commercially in Tesla Coils for spark gap radio transmitters for wireless teleg- raphy until the 1920s. Tesla experimented with the Wireless numerous configurations using two, sometimes three, coupled resonant electric circuits. These Transmission circuits were used for innovative experiments in electrical lighting, phosphorescence, X-ray of Electricity generation, electrotherapy, and ultimately the Gary Peterson transmission of electrical energy without wires.
