I was thinking to create a feasible method to effectively harness power of lightning. Even though lightning does not have enough power to meet global energy requirement, i was intending to do it for knowledge's sake. I realized, in order to tap into the vast electric charges of clouds, it was necessary to create a conductive channel so that the charges get a conductive path. i found it was possible by 1)by creating a plasma channel by a laser, but it would have to be cw(continuous wave) laser so that the channel can be maintained. But I believe that is impossible since the power requirements of the said laser would be humongous. 2)by dielectric breakdown of air, which is not possible for lightning harnessing purposes 3) By creating a beam of positively charged ions and artificially creating positive streamer. this channel can be electrically connected with a Single ended primary inductor converter which in turn can be used to charge capacitors. These capacitors can be of a high discharging time and less charging time. these capacitors can then directly be used to power equipment or convert dc into ac at required frequencies using power inverter. now my questions are 1) does sepics of such rating exist which can handle 30 kA ? 2) is there a wavelength at which air ionization occurs at very low energy ? 3) how far can a positively charged ion beam go before getting neutralized ?
