dear colleagues, what do you think about the transfer of energy by creating a waveguide in air(waveguide, stimulating air(laser, microwave radiation, or both) and create a plasma in the air with an empty Central part and so forth) for the flow according to the obtained waveguide current, electromagnetic radiation, laser coherent, microwave. Is it possible to pass thus high energy?? I also thought possibly it may be a jet of gas or liquid for a contact to use for the same purpose, without ionization? Thinking and the search for promising ways of energy transfer for drones, quadcopters and other small air transport
