I can explain the Mustafa Circuit fairly easily. First off, it uses Mains input to a transformer and needs to be fired into the high side of one of the transformers, irregardless of transformer type, they need to be identical transformers and they need to be tuned in resonance. If the two transformers are checked with an FGEN and scope, they need to be identical to work and they need to operate at the same frequency as the input otherwise they will NOT pass energy.
I saw Sergie state he tried replication and this can't be done by merely using Antanas' variables. First off, Antanas is using 240v and the system runs at 50hz. Sergie tried to use the same sized cap for a 120v system and the coils are different inductances, probably have different style cores, etc. The transformers here need to run at 60hz, be exactly the same model for step down then back up, then the resonance part in the isolation windings tied in the middle need to use an AC cap. If you don't have an AC cap, the coils will just shut down and pass nothing, or, if they aren't in resonance they will pass nothing.
So, here is what I did to make it work. I bought two transformers off of EBAY. They are 120 to 24 transformers, 500VA. I measured each coils inductance and wrote them down. Then I labeled each one because they were slightly different. I tied the 2 secondaries together and measured their inductance. wrote that down. Then I connected the secondary coils to an FGEN when tied together to see if they were in resonance at the correct voltage and they were not. I had to tune them so they were by adding capacitance. To figure out where you need to be there is an easy calculator to use online at http://www.deephaven.co.uk/lc.html
and I used the total inductance and line frequency used in my home to determine the ac cap needed and ensured it was good for at least 4 times the step down voltage to cover for resonant rise, which in my case is about 2 times without load, but to be safe allowed double what I needed so the cap didn't fail. The caps can't be electrolytic, they are for dc only. I like MICA self healing caps and poly caps when tuning, and they are cheap enough for 120v caps anywhere, even from Mouser or Digikey.
So, the moral of the story is we need resonance to make the electrons march, the transformers don't transform the energy being used, the energy combination between a pulsed dc and a resonant ac wave is what we need. The load part of the circuit needs to fire into another cap and we need either an scr or a cap and another transformer to do this. We can also add diodes to rectify, an electrolytic at the tail of the circuit, then inject a pulsed dc wave and tune the frequency until we get power output, or, we can use a simple cap and spark gap to do this. The cap at the tail of the circuit using the spark gap needs to be electrolytic and it has to have a resistive load on it so the cap doesn't explode. Cover exactly what he uses for a cap to cover the energy used if you use 240v, if not, then you have to reduce the voltage of the cap to the output voltage of the circuit based upon the voltage created with your resonant rise (on the other side of the coil of course.) the circuit becomes a self oscillated charge pump that uses the sinewave as a return path for the DC signal, superimposing the spike, then a dc flat line, which returns to the beginning of the cycle through the sinewave. It's hard to imagine but that is how it works,. those are the motions of the electrons. This is a quantum effect and I call it 3 dimensional electron flow, where the quantum dimension is the electron following a return path in the wave to harvest free energy off of itself. This has been a classified Russian energy system that was stolen from US Dr. Moray. Moray's system didn't use anything hard to make it function. The input energy ran transformer and did the same thing. Dr. Moray added other components to stop others from replicating. And, he only allowed 3 or 4 people see it in person. One was his lab assistant that stole it from him and knew the operational build criteria. Others saw metals, and what he called the moray valve. The operation of the valve was to inject the additional; frequency to allow the return path of the dc current through the sinewave in resonance. It's a simple principle,. the real fun is to take and harvest the energy it makes because it is deadly. Smith's system works on the same principle, that is why nobody has replicated it yet because they need the push pull as Antanas has. Antanas and myself are the only ones right now who understand this, I am the person needed to draw the energy from the circuit and apply it to retrieve the energy in an output. Sadly we need to use a very large battery charger to charge super cap banks, then invert it and take advantage of the massive energy since the system charges super capacitor banks in 1/60th of a second or one cycle, then while using the energy, since it only take 1 cycle to charge, the caps are recharged before the system could drop 1/4 volt. Leaving unlimited and useful energy.
Please copy this and share it. It is the answer to the energy crisis in the world, and it is Tesla's baby. I do not wish to keep explaining how this is done, just make it as I stated and it will work flawlessly.
Each US resident's home that has a 20 amp breaker could be run off of one of these circuits. They are nearly the same energy output, but we need to invert and clean the wave up to get a clean signal and no burn up or noise in the lines.
