Forget free energy talk
free energy as in wind turbine is doable. over unity is something else. claim of self sustaining electric circuit is a different league of game.
btw, do you have oscilloscope to see the current changes when you change your wireless load? can you do 5 hours using the same motor in the video? if you cant give a clear figure on your circuit's efficiency or any other sensible spec, then i'm afraid you dont have anything as reliable claim as even a "nearly self sustaining circuit". interesting project btw, anybody with enough free time may improve the circuit for you, but if the objective is a self sustaining circuit, it is a clear delusional attempt. you may choose to realize it the quick way here in this forum, or the slow way through your own venture...
you need to understand to improve it, one need to understand whats going on in the magnetic field of the transistor's base node, make few measurements and probing, not a single eyeballing your video and find an optimized solution on the first try. but lets hope somebody around here have done similar project and present to us the optimized circuit in silver plater. but over unity? no!
