ELECTRIC ENERGY TRANSMISSION METHOD AND DEVICE Russian patent published in 2011 - IPC H02J17/00 

FIELD: electricity.

SUBSTANCE: positive result is achieved due to available metal tubes used as guide channel for energy flow instead of electric conductors. The above tubes are installed for other purposes, e.g. for pumping of liquids or gases. Electric power is transferred by means of excitation of resonant oscillations of magnetic flow in the tube wall. At that, magnetic flow at resonant frequencies within (0.3÷300) kHz is excited in two opposite directions azimuth-oriented relative to tube axis. Excitation is performed with system of inductance coils of transmitting device powered from electric power generator at resonant frequency of the system. Around opposite directed magnetic flows the eddy electric field appears inside and outside the tube. Available variable magnetic and electric fields of the described spatial configuration creates energy flow along the tube. Design of receiving system is identical to transmitting one, due to which, when being in energy flow, it generates e.m.f. at outputs of terminals, which can be used for power supply to electric receivers or for obtaining mechanical or heat energy.

EFFECT: increasing transfer efficiency of electric energy and saving of materials of electric conductors.
