STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

[Omnibus]

As promised, here's the correct schematic diagram of the setup and a graph of the experimental results with secondary transformer coil loaded. I'll show you in a separate posting results from unloaded transformer -- OU from just a coil with core. Notice in the diagram the correct measurement of the input voltage (output voltage is redundant but the input is not and that was my error in the previous diagram and data I posted). Also, note the two additional coils in series with the secondary coil. With these additional coils the OU effect which is already there increases. Another interesting finding is the increase of current amplitude with the increase of frequency within a certain interval of frequencies, contrary to what's expected when impedance is increased. Notably, the voltage stays constant during that current increase with frequency. Have to figure out how to present graphically that effect. For now enjoy this:

@Omega_0,

Calorimetry is a very tricky business. For one thing, if you immerse the transformer in oil you have to have a way to stir well the oil to avoid developing of hot spots. Very careful calibration is also a must. I do have a high end four place thermometer (measures temperature with 0.0001oC accuracy) --  Thermometrix Precision Thermometer Model TS8901 -- but to do quality calorimetry with it, aside from the other problems (stirring) I have to sit down and figure out how to program it via its RS232 or the GPIB port for a long term data acquisition. Don't feel like doing it right now. If someone is willing to help I'll appreciate it greatly. As for the VoIo = ViIi thing will have to post separately an Excel datasheet.

Back to calorimetry -- I don't think that even carefully done it will resolve the problem with the correct current measurement because the integration of the electrical power will again be based on the oscilloscope data. The best thing is to avoid calorimetry in such cases. The I and V data, correctly taken, should be enough.

@Omega_0,

Tried to upload an Excel file but even compressed it's too big for the size allowed here (maybe that's due to the fact that I moved to Excel 2010). I'll say it in words, though -- from the data it is seen that the OU effect is almost exclusively due to the heating of the primary coil. In other words the equality VoIo = IoIo is nowhere near obeyed. All the action, as I already mentioned, is in the primary coil and you don't even need the secondary one for OU to be observed.

Nice work omnibus! I am very happy to see the hard work paying off to some extent I believe you may have finally found this red herring that other replicators are failing to see... The diagram and data provided should be more then enough for any willing replicator to confirm.

Let the confirmations begin.

You can try reducing the size by deleting the data for all but two pulses (at a particular frequency, all frequencies are not needed).
Or upload it on mediafire.com and post a link.

IMHO, since you are measuring the output as total heat emitted on both sides of transformer, a direct measurement of heat would be more accurate and trustworthy. The I^2*R method relies on very accurate values of R and I (both sides), and can produce errors.

I agree with you that the calorimeter will still require an accurate measurement of Vi and Ii, out of which only Vi is easy to measure. Ii can be measured by a calibrated probe. IMO to start with, you don't need a high end thermometer, just simple digital thermometer will do, note the temperature by hand in a notebook.

If the transformer equation (Po = Pin - losses) is not holding, it is surely an anomaly, because the losses are coming negative.
