Auroratek demonstration from Bill Alek at TeslaTech conference

[MileHigh]

We have the most earth-shattering event in the history of the world - and the first deployment of this technology will be a small "don't ask to see the BOM" motorized bicycle!

Q:  Why not build a trial 10 megawatt free energy electrical generating station instead?

Inquiring minds want to know.

You cannot use one of those infrared temperature meters to read with any degree of accuracy when the emissivity of the surfaces or distance is different. Often you will get  a difference between two readings when measuring the same surface / same distance.

Matched Thin film Platinum 100 Ohm resistance film sensors used in a differential bridge circuit would be a better choice when trying to differentiate one degree or less.

Also the cores will take quite some time to heat up as the loss is in the copper wire, which is not efficiently  coupled to the cores thermally. At this low frequency (3200Hz) with metglass, core loss / core heating  is hardly an issue.

I agree that the emissivity differences make the IR measurements a joke.  I agree that a difference measurement using thermocouples, or preferably thermistors using well-shielded cables is the way to go.  Do that following TinselKoala's protocol:  Let an unpowered device come to equilibrium in a room with still air, or where the device is sheltered from air flow and record the bridge voltage.  Then set the device up to operate, give it plenty of time to reach equilibrium, and record the bridge voltage.  That will give a clear indication of which way the temperature goes relative to ambient when operating.

I tried to understand and simulate:

Getting the right K values without a set of measurements on each of the coils with the other two open and with each and both of the other coils shorted, could be a challenge.

trolls seen squiming in their chairs and overheard saying: there is always some little detail we can find to turn a mole hill into a mountain.   if not we'll make something up that sounds believable.

one year into the future.  tk caught in a photo riding the jetson scooter down his street while still denying this is a valid device.

The little detail that the power supply must be included in "input power" measurements?
The little detail that a self-charging battery charger/scooter system was supposed to be demonstrated... but was not? The little detail that claims are being made without the solid evidence that should be provided along with the claims? Yeah, those little details always seem to interfere with claimants giving solid proof of their claims, don't they.

Where is a graph of temperature vs. time of the "cooling off" transformer? You may recall that I provided dozens of such time-temperature graphs for anyone to look at, for free, during the LMM debunk, all of them fully documented with raw data presented for inspection, and I wasn't even making extraordinary claims.  But Alek comes along and just tells you that a current-carrying transformer cools off when operating, and you believe him, without seeing any data at all.

OK, fine. You buy me the scooter and I'll ride it around and let you know, with 100 percent fully preserved and inspectable raw data repeatable by anyone with the skill, whether or not it needs to have its batteries ever recharged by an external charger. If it doesn't need to be recharged during that year of operation, I'll buy it from you for twice what you paid for it and make a public apology to you and Alek and everyone else on YouTube.  But if it DOES need external recharging.... I get to keep it and you are out the purchase price, AND I'll be invoicing you for my standard consulting fee. What do you say? Let's put YOUR money to the test.

You see, the reason I put forth challenges like this is because I _know_ you won't accept them. Your own belief in the reality of Alek's claims is actually not that strong.

What I saw in the video:

A conventional line transformer driven by an audio amplifier.
A "SFT" tranvformer that consists of:  A primary labelled as 3.07mH 1.4 Ohms, coupled to two secondary windings one labelled a: 120mH 19 Ohms and the other 122mH 15 Ohms.
A wirewound power resistor connected by patch leads to a circuit board.
An audio power amplifer connected to a function generator  where the audio amplifier drove the DUT

A measurement where the input was  ~10.75V rms @ 3200Hz, and the current ~1.466A rms, and where the oscilloscope reported a phase shift of ~78 degrees.  The output meter values were 11.39Vrms, and 0.459Arms.

The apparent input power:  15.8 VA.
The apparent (and assumed real) output power:  5.23VA and 5.23W

The real input power was calculated based on the oscilloscope's phase angle reading which varied from 74 to 81 degrees.  Bill Alek chose to use 78 degrees and got: 3.28W real.  But cosine values change proportionately very fast in this area.  The respective cosine values are:  74 deg 0.276, 78 deg .208, and 81 deg 0.156.  A small error in the phase angle measurement results in a large error in the calculated real power. 

Bill Alek later presents his demonstration of a measured phase angle greater than 90 degrees when the transformer secondary is shorted.  Under conventional thinking the resulting phase angle would approach but not exceed 90 degrees under such a condition.  Bill Alek's scope reports 102 degrees.  One way to interpret Bill Alek's data is to assume that conventional physics still holds and what Bill Alek has is a phase error that over reports phase shift by at least 12 degrees near 90 degrees.  If we apply that hypothesis to his unshorted measurement we get a phase angle of ~66 degrees, and a real input power of: 6.42W which results in a decidedly under unity device.  Another interpretation is that Bill Alek's reported phase shift is correct and modern physics has been overturned.  Given that the apparatus appears to be no more than a three winding transformer with lots of leakage inductance, there isn't anything extraordinary about the apparatus' construction that suggests extraordinary behaviors should result.

It is up to Bill Alek to show that his measurements are in fact valid, when it is almost certain that they are not.  The fact that he refers to pairs of loosely coupled single windings as bifilar, which they certainly are not, does not instill confidence in his mastery of the subject matter.  Neither does his inappropriate use of a IR thermometer, or failure to show null tests that establish the accuracy of his measurements, particularly phase-shift.
