By my estimation 1.9 Arms in the secondary is pushing the limit for 20AWG in a transformer, where a safe current limit is 3 A/mm^2.  20AWG is about 0.5mm^2, which would work out to 1.5 Arms.  So if you ran the thing for a while at the level, you might over heat the primary winding. 

My guess is that you could add some more light bulbs.  The QEG has the interesting behavior of putting out more power as the output resistance is increased, right up until the point the resonance get damped out. 

Did you say the frequency of the primary was 192Hz?

You might want to see what kind of voltage is developing across a single lamp.

What are those 100W lamps?

Ari,

Can you make a posting where you state your measurements and observations?  Also a simple schematic of your setup and your measurement points?

It's important to present your measurements yourself, along with your YouTube clip.  Even if the measurements are disappointing it's very important to state them.  Everyone that does a replication should do the same thing.  That also applies to the 'official' teams in Taiwan and Morocco and everyone else.  I have to assume that some of those teams are also following this thread.  Proper measurements and proper documentation are critical issues in understanding what is going on.

For example, what is the output frequency?  Are you using a clamp-on meter to measure the current through the light bulbs?  Is the clamp-on meter able to properly measure current at the measured output frequency?  If you are not sure then what is the manufacturer and part number for the clamp-on meter?  Is the clamp-on meter only able to measure the RMS value for a sine wave or is the clamp-on meter a true-RMS clamp-on meter?  What is the voltage waveform like across the light bulbs themselves?  That's an example of how important it is for any experimenter to properly document what they are doing and how and where they are making their measurements.

About the spark gap, Woopy gets the credit for doing that one the best.  He bought sealed spark gap components, real electrical components, and they are rated by voltage.  He was using them in his clips months ago.  I suppose you can get them on DigiKey.  I also assume that they are rated for average and peak handling power and you may have to pay attention to that if you want to purchase some for the QEG.

From what I gather, a spark gap is principally used as a high-voltage switch.  Unfortunately, the spark gap has taken on a life of its own on the forums, and people seem to think that a spark gap itself can do something special.

In looking at the schematic for the QEG, you can see how the spark gap will just short out the secondary Neutral with L1.  So I view that as an output power killer.  It will suck energy out of the QEG and burn it off in the plasma of the gap every time it fires.  From what I can see on paper it appears that it will do nothing to improve the performance of the QEG.

If you believe that it will improve the performance of the QEG then you should try to show full measurements with and without the spark gap.

20 AWG has a minimum diameter of 34mils.  500cma is acceptable for many designs and would allow a bit more than 2A.

From my days of studying output and power transformer design for musical instrument amplifiers, the rule of thumb was 3 A/mm^2, although that was a conservative figure.  So, 2 A/mm^2 for the 20AWG would probably work fine without over heating in the QEG, unless the machine was operated for a long time while sitting out in the sun on a hot day.  Such a occasion might occur if the QEG ever found its way into common use as a generator, as it does on a regular basis for musical instrument amps sitting out on stage.
