Henry Moray's Device Greatest of All Time?

In the early 1900s, Henry Moray demonstrated his own device which stimulated the existing energy waves of space and then received the inflow of excess energy that would follow.  He was able to receive 50 KW for days without end.

Excerpt from "Explanations of the Oscillations of Radiant Energy" by Thomas H. Moray:

This I have been able to do through the use of certain oscillators that I have made and of which doctors of science have said are the most powerful devices known to science today. With the use of these oscillators and the oscillating effect of condensers which I have sometimes explained in the following way to those who are not acquainted with the back-rush effect of condensers (capacitors), and which may serve to make my point now. When an elastic substance is subjected to strain and then set free, one of two things happens. The substance may slowly recover from the strain and gradually attain its natural state, or the elastic recoil may carry it past its position of equilibrium and cause it to execute a series of oscillations. Something of the same sort may also occur when an electrified condenser is discharged. In ordinary language there may be a continous flow of electricity in one direction until the discharge is completed, or if proper use of the condensers are made an oscillating discharge may occur. That is, the first flow may be succeeded by a back-rush, as if the first discharge had over run itself and something like a recoil set in. The condensers thus become more or less charged again in the opposite sense, and a second discharge occurs accompanied by a second back-rush, the oscillations going on until the energy is either radiated or used up in the heating of the conductors. And if your device will oscillate in harmony with the oscillations of the Universe, or in other words, if the device is capable to synchronization with the vibrations of that energy through space then the oscillations will go on forever. No one can call such an arrangement perpetual motion any more than one can call the motion of the earth perpetual motion. My device oscillates because of the oscillations of the Universe.

Why is it difficult to replicate the device with such tremendous output?  Because the process of tuning into the universe is not a very simple one.

"Oscillations by synchronization are started in the first stage of the circuit of the device by exciting it with an external power source such as a potential difference between two points. The circuit is then balanced through synchronization until the oscillations are sustained by harmonic coupling with the energies of the universe. The reinforcing action of the harmonic coupling increases the amplitude of the oscillations until the peak pulses spill over into the next stage through special valves which then prevent the energy from the proceeding section from returning."

It is the balancing process to achieve harmonic coupling which is not clear.  Clearly, the oscillations would have to be tuned to find the frequency which is strongest at the time of operation and the problem is greatly complicated by the fact that the device would also need to match up to the phase of waves coming from space.  If you had a good frequency, but the phase was off, the waves could actually cancel each other out!  Today, we could use computer technology to create some kind of algorithm that would make increment adjustments until the optimal timing was found.  But obviously, Moray had developed a few tricks because witnesses watched him perform the operation in minutes at different locations!
