This presentation by Yan Duan explores a groundbreaking method for long-distance energy transmission using a single wire, reviving concepts pioneered by Nikola Tesla over a century ago. Unlike traditional closed circuit systems, this novel approach utilizes resonance circuits to transfer energy efficiently. By selecting appropriate capacitors and inductors, a standing wave is formed in the wire, allowing for energy transmission with an optimal phase difference. This method signifies a potential leap forward in electrical engineering, offering insights into efficient power distribution.

Single Conductor Energy Transmission Presented by Yan Duan September 13th2013
Background • Conventional way to transmit energy at a long distance: Closed circuit is always required. • A “new” way to transmit energy, with only one single wire.
Tesla’s Work • Not that “new”: back to 100 years ago, the ingenious scientist/engineer (Eng Phys) N. Tesla was already able to implement a resonance circuit, thus to use only a single wire, energy could be transferred from station 1 to station 2.
Simple Explanation • By choosing suitable values of capacitors and inductors, the displacement current in the single wire could form a standing wave, thus a resonant wave, with a phase difference of 90 degrees between displacement current and voltage. That is with a standing wave, the long-distance divided two parts of the "circuit" could be regarded as simply integrated, thus the energy can be transmitted.
