Exploring the Inductive Resistor Heater

[TinselKoala]

Well, you know that Ainslie is claiming that she will perform some kind of demonstration on June 1st, right? A demonstration of just what, I suppose we shall have to wait and see.

But here's a simple challenge for her and her "team": Simply repeat the demonstration shown in the second part of their earlier Demo Video, with the exact same circuit and construction layout they used then, but with all six batteries, providing 72 volts, instead of using only four at 48 volts as they did in the video (without explaining why at all, no matter how many times they have been asked.) Bring 700 mL of water "to boil" with that exact same circuit, built the same way, the same load, and 6 full 12 volt batteries. After all, that is what their "paper" claimed to do, NOT with only 48 volts.

But they won't be doing this, even though it's easy to set up, reasonable, and is what is claimed in their "paper" to have been done.

TK,

I could be wrong, but the way I read it, she is likely going to show that the battery voltage drops less in a given amount of time when two different load profiles are applied.  This I gather from her desire to abbreviate the time required to perform the tests. 
 
Is this proof of OU?  No.  It is only proof that a lead acid battery can have different capacities under different load profiles, even if the two load profiles produce similar average loads.

Would not proof of OU with this type of test, using batteries, require that more energy is able to be drawn from the batteries than is required to charge them?  That would require several well measured charge/discharge cycles to prove.  Not having access to the electrolyte to measure its specific gravity would make this somewhat difficult, although doing a CC charge cycle terminating with a CV charge to a predetermined minimum current might be an acceptable alternative, if repeated sufficiently.  Accurate sampling of Vcharge and Icharge would be required and calculations made to accurately determine the energy required to recharge the battery.  An RC battery A-Hr/wattmeter might be useable as charge current would be measured at DC.

However, if the "extra energy" is coming from the magnetic and material properties of the inductor as per her thesis, then why is a battery even required?  If the "extra energy" can only be observed when using batteries, does it not seem more sensible to conclude that what is actually being proven is moreso related to the vagaries of the batteries themselves?

It amazes me how little desire either of them seem to have in making their circuits work with a well filtered DC supply.  As I have suggested, a network can be inserted between the supply and circuit that would mimic the AC and DC characteristics of the battery so that the circuits will oscillate or ring as they do with a battery.  Alternately, a DC supply could be connected to the batteries and isloated with an inductor in series therewith to prevent AC loading, and the steady state voltage and current required from the supply to maintain battery voltage/charge measured and used to provide Pin. 

Proving that the circuits produce more heat when driven with a well filtered, easy to measure DC supply, than is produced when that same amount of power is applied directly to a resistor, would be much more interesting than proving that the batteries have different capacities when different load profiles are applied.

Yes, or equivalently, that the batteries do not discharge or that they even increase in charge level during the experimental run. Of course neither of these things occur in Ainslie's or Gmeast's experiments. The batteries discharge normally, and the total heat energy output by the load and the circuit does not exceed, or even approach, the energy required to charge the battery in the first place. Neither Ainslie nor Gmeast have ever shown any data that indicates otherwise. And of course when capacitors are used to power the circuits, it's easy to see that there is no magic, no overunity, no "advantage" from an oscillatory discharge, and of course the capacitors run down normally and make the "magic waveforms" all the while until their voltage drops enough for the circuit to die.

TK,

Even though she still does not understand how Q2 is biased on by having its source pulled negative wrt the gate, or how the DC bias current flows thru the FG, or how AC current flows thru the intrinsic MOSFET capacitances, she has, at least, apparently backed off on the cop=infinity claim.

My impression is that Rosemary is aiming to show that for the same heat rise on the load resistor, the DUT battery will outlast the control experiment battery, using the 10V mark as the cutoff.

She also appears to be claiming that the amp-hour (although she incorrectly states watt-hour) rating of the battery will be exceeded when used in the DUT.
