title: ENERGY GAIN BY MEANS OF RESONANCE IN THE TESLA COIL
abstract: An analytical review of publications on the problem, first formulated by Nikola Tesla, generating «free» energy from the air in the surrounding space has been presented. The hypothesis of the resonance phenomenon as a «key» to the air energy has been advanced. The main unsolved problem is the extraction of «free» energy (proposed to call it «resonance») and its supply to the electrical load have been noted. It is expected that the quality factor of the secondary circuit must be large enough
