Im not knocking his work. Just saying it is hard to hear his voice and not be distracted by it.

patent from 30378  quote:

In the arrangement of the excitatory magnets and the induced, our generator
has some analogy with dynamos, but completely differs from them in that, not
requiring the use of motive power, is not a transforming apparatus. As much as
we take, as a starting point, the fundamental principle that supports the
construction of the Ruhmkorff induction coil, our generator is not a cluster of
these coils which differs completely. It has the advantage that the soft iron core
can be constructed with complete indifference of the induced circuit, allowing
the core to be a real group of electromagnets, like the exciters, and covered
with a proper wire in order that these electromagnets may develop the biggest
attractive force possible, without worrying at all about the conditions that the
induced wire must have for the voltage and amperage that is desired. In the
winding of this induced wire, within the magnetic fields, are followed the
requirements and practices known today in the construction of dynamos, and
we refrain from going into further detail, believing it unnecessary.


So Figuera gives some clues here as to the coil construction.  Obviously it's not a classic induction coil as it differs completely. But the basis is a Ruhmkorff coil.

This guy is nearer the mark. You need to understand interrupters, var, hf oscillations circuits produced by the tank circuit.  I am not into this configuration but feel that builders need to understand the principle. I believe  NRamaswami found a solid state way to produce the effect. I would really like to see NRamaswami's  scope shot and I'll bet it's full of spikes.

Here's a "solid state" way of producing ... wait, what effect are you talking about? Voltage amplification by rapidly collapsing magnetic fields, in a resonating tank circuit full of reactive power? Ok, we've got that covered:

(30 VDC input at less than 2 amperes)

Sorry... I'm not about to connect my Ammeter _directly across_ that output ....   

So.........
accordingly the 555 pulses the power transistor to open the gate to let a 9 amp spike to invoke a magnetic field that jumps a gap and invokes a magnetic field into the secondary and ( if not connected to anything ) goes.........where?

Not quite. There is a 555 but it only provides the "gating" at audio frequencies. The actual resonant oscillation driving the system is produced by a Phase-Locked Loop circuit that keeps the oscillator tuned to the resonant frequency of the secondary. The PLL chip (4046) picks up the e-field oscillations by an antenna loop at the bottom of the secondary, and this is used as feedback by the PLL circuit. The pulses from the PLL are connected to a current amplifier to drive the Gate of the single mosfet power transistor. The secondary circuit is operating at about 736kHz, and changes by a few kHz either way as the PLL circuit keeps the coil in resonance. The 555 timer just gates the output of the PLL circuit in order to produce the staccato sparking sound at audio frequencies. It is not involved in the actual resonating of the circuit, and without this gating the arc is constant and silent.
If nothing is connected... the frequency and voltage are so high that the environment itself completes the circuit, either by direct ionization or by capacitively coupling between the top of the coil and the Earth.
Yes, you could think of it as a magnetic field from the primary, "jumping the gap" to the secondary. Since I am using air-core coils, there is no magnetic core saturation or power wasted in eddy currents heating the core to worry about. The collapsing field from the primary, each time the mosfet turns off, induces a voltage in the secondary, and since it is tuned to resonance, the secondary voltage builds up to a very high value-- as high as possible, in fact, limited by the spraying off of charge from the top terminal as corona.
The input voltage is 30 volts DC and the output voltage is just over 30kV, as measured with a sphere gap: a voltage amplification of over 1000x. The "turns ratio" is only 84 to 1.

@A.King

Sir..Thanks for pointing out 30378 where the poles are defined as opposite poles and also for providing for the attractive forces. Whereas the induction coils are based on repulsive forces the Figuera Generator is based on Attractive forces. You are quite correct in your statement about the interrupter but where is the capacitor in the Figuera patent. I do not see any capacitor arrangement there and no tank circuit there..I apologize if there is a mistake on my part and it is due to my lack of knowledge. I do agree that I modified the primary to have a higher frequency so the input cannot go up beyond calculated limits but I do not understand where is the capacitor in the Figuera circuit..Please advise. Actually this is the patent that convinced me that we must use only opposite poles and not identical poles and in any case I was not getting any voltage in identical pole arrangement of NS-SN-NS as suggested earlier in the forum..I then used not only the attractive force but also the repulsive force to make the modified device. I do not have any oscilloscope and I'm a poor researcher using my own small money to do these things but I cannot afford any thing any more..I came out of the vacation to thank you for your postings on this point.

@TK..You seems to be the most prolific poster knocking out free energy device claims but thanks for acknowledging or indicating that while the input wattage is around 60 watts the output wattage would be far higher in your demonstration of the Tesla Coil..Can you please do an experiment..Put Water in a copper cylinder with open top and surround it with plastic and then copper and secure it well.. Place the water container at some small distance to the Tesla coil so the spark will hit the outer copper. Take a very thick probably 6 inches thick copper rod well insulated and put it to ground. Make the ground point also wet. Can you find out what is the Amperage and voltage from your 60 watts input..I think it will not be 60 watts but way more higher..Do you disagree? Be careful though. I have made a low voltage high frequency circuit of Patrick and we did not find any current coming from the two electrodes.  Then I put two Tens carbon electrodes and held them in my hands and nothing and let the electrodes slip..You know what the carbon electrodes got fire and burnt to my shock. While High Frequency electricity is safe even at high voltages a slight drop of water can change all that and can make deadly current..Water contains a lot of amperage and you may please test it and tell the forum if this is true or not..May be Ramaswami is bluffing you see..It is your equipment..your place and your measurements and Ramaswami cannot deceive here..But please be careful..High Frequency or otherwise once the circuit contains water the electricity is deadly..So please be careful if you elect to do this experiment. I do not have the facilities to do these things.

Hello All,

http://www.loneoceans.com/labs/ignitioncoil/
Here's a simple car ignition coil setup to deliver a spark...

So...what you're stating is having 7 of these circuits to deliver a spark across each of the 7 transformer's air gaps...?

No, that's not quite correct, you don't have to "switch off the input" to extract real power from that which is stored as reactive power in a tank circuit. My video demonstrations of wireless power transfer and the microQEG illustrate this quite well. What is necessary is that you don't extract real power faster than it is being replaced into the tank circuit by whatever is oscillating it. Because if you do, then the stored reactive power will collapse until it's replaced by the source.

but....

How much power do you need to jump the air gap?
the BDX53 s provide up to 9 amps and the 2N3055 s provide up to 35 amps
100 watts or 400 watts
