guys,


before we start squeezing our heads, devise setups and applying ideas (although fun), we must consider in the first place. What are we after?
Jack no skills said that! OK he said a clever and interesting arrangemet.. furthermore claimed OU.


Any proof of that? photos of setup?  Crystal clear videos with appropriate measurement equipment placed as suggested? (Pin and Pout measurment)
What the hell with this forum that anyone suggesting the impossible (?) is treated as gury and demi god, whereas the burden of proof lies on the replicators! lol


My hunch is telling me, jack, saw his profound mistake as he claimed "input series bulb is dim and cold whereas the output is hot so it must be OU", and i said " current is not a energy index, since different voltages are in play.


Am i wrong?

Hi baroutologos,

I agree with you, we have not seen any proof yet...  Somehow Jack avoids reflecting on such questions like a simple photo of his setup.

"The input series bulb being dim and cold and the output one is hot" method is not good at all for making conclusions, unfortunately, you are correct the input and output power is what should be considered, not the brightnesses.

Hi Jouleseeker,

'Tuning' the primary coil of the 2nd transformer can cause phase shift in the coil current and voltage and in case the 60 Hz resonance in the primary is approached the primary becomes a high impedance coil as any parallel LC does, and this involves a smaller input current into that primary and higher reactive currents inside the coil/capacitor. If your primary coil's inductance could be measured at 60 Hz, then the resonating capacitor value can be calculated, in this case you could see what effect this may have for the efficiency.

I didn't want to say anything because I end up being labelled the "bad" guy but finally you said something and I will take this opportunity to expand on what you said.

To the people in this thread, go back and look at the very first posting made by Jack.  Take a serious critical look at it.  What do you see?

It's more like what you don't see.  There are no critical measurements made at all.  It's all just subjective anecdotal stuff like "This light bulb is dim and the other light bulb is brighter."  That means almost nothing if you don't know anything about the actual voltages and currents and possible phase relationships for the input and the output.  There is nothing like that in the first posting and it's also very obvious that Jack is a beginner.

If you want to take my advice you should all go back and seriously debate Jack's first posting and the points he makes and decide if what he says has any merit.

Beyond that there are other issues but they don't even need to be discussed.  The first and foremost issue is the first posting in this thread.  Is it legit or not?  I am not implying any deception being made by Jack at all.  It's all about the proposition and the measurements (or lack of measurements) and the logic that is being proposed in the first posting.

In a way, this is a microcosm of the original RomeroUK building frenzy.  There were big unanswered questions (Can you show us the output of the FWBR bus?) and as a result people went crazy on a building frenzy with incomplete data.  Just a few simple questions would have busted Romero and would have prevented a whole year's worth of useless experimenting.

Very well said.

Numbers mean more than opinions and and this needs numbers to be validated, not opinions. Would I love to see the numbers-yes

The BS not so much...

I don't spend energy on being negative (story below).  I'll leave that to others.  I have said a couple times in this thread that my experiment with two 1:1 torroids showed "joule thief" like results.  Joule Thief circuits amaze but it is just a transformation of power into another form.

For those of you still exploring this, do me a favor and try this:  Feed the circuit with 120 vac but through a common wall mount dimmer.  The dimmer chops the AC sine wave into a saw tooth.  This will simulate the rapid on off we get with a transistor.  My guess is you will see the "Joule Thief" like result I saw.  When the field collapses in the first primary there should be a spike in the secondary.  This spike gets doubled in the second transformer because the voltage is additive if its in phase.  Amperage should drop.  If you feed this spikey voltage to a resistive load it will just convert to watts.  If you feed this spikey high voltage to something other than a resistive load it might be interesting.

_{I left my fiance with my Triumph TR4 while I was on a business trip.  When i came back I asked her for the key.  She handed me the mail box key.  I told her that wasn't the key and she said "yes it is".  I told her, "I know the key to my car and that isn't it".  She said, "Well that's the key i have been using".  Sure enough the mail box key fit the car ignition.  From then on in life, I am slow to say someone is wrong.}
