Kapanadze Cousin - DALLY FREE ENERGY

[NickZ]

  According to Geo's tests, he was able to light a load of 3.5kw worth of bulbs, using 36v input, at similar to grid lumins.  Although he has not shown this, yet.
  So, we may have a long ways to go still, to catch up to his stated results.
  If I got that wrong, I trust that he will correct me.

  As we don't really know the rated values or compositions of the cores we are all using, it's hard to get an idea on the which ones may work best. As even the flyback cores are not all the same.
But most people can at least obtain the Flyback cores, for free sometimes, or by ordering them. Possibly not so, with the yoke cores, which come in sizes up to about 5 inches, or so, and may also be of varying permeability as well as compositions.

I'm still patiently waiting for Geo's motor-generator set up video. Hope his GF isn't too distracting...  or we might have to wait a long time.

The open circuit battery voltage is another faulty method of estimating the energy content of a battery. Especially a lead-acid battery.

Of course yes, it is! But one has to know that a 12V battery is full at ~ 14V and empty at ~ 11 V and need to have the exact graph W/V.

At least the pencil works in space, but the following methods are used on Earth by the members of this forum, despite that they do not work:
1)   Multiplying average Volts by average Amps to obtain average Watts, for non-DC.
2)   Multiplying RMS Volts by RMS Amps to obtain average Watts, for non-DC or out-of-phase AC V&I.
3)   Measuring any Volts or Amps outside of multimeter's operating frequency.
4)   Eyeballing a light bulb
5)   Recording a light bulb with an ordinary camera w/automatic aperture
6)   Using an incandescent light bulb with a coiled filament for HF AC and assuming that it conducts HF AC with the same impedance as DC
7)   Using non-incandescent light bulb.
   Heating water with resistive heaters (interfered by evaporation, ambient temp, thermal inertia, gross mass measurements)
9)   Evaporating water (subject to temperature and pressure interference and water loss due to misting, gross mass measurements)
10) Measuring the temperature of one resistor in non-isolated environment

I am completely agree with you for all these former items and very thank you for having made this list, wishing it could inspire our experimenters to improve the value of their time spent by the bettering of the quality of their measuremnts.

11) Treating the open circuit battery voltage as on indication of its energy content.

Here depends essentially how the data are treated.

The following methods work but have several drawbacks, the main one being the inability to discount reactive AC power flowing in an AC circuit (such as when a capacitor is connected to an AC voltage source and on average exactly as much energy flows from the supply to the capacitor, as from the capacitor to the supply.  This results in no net energy flow over one cycle. In other words: real average Watts should be ZERO over one cycle, in that case)
These methods are incapable of measuring the real AC power - the are capable of measuring only apparent AC power :

12) Differential calorimetric measurement o two identical resistors in two identical but mutually isolated environments (one resistor with a DC the other one with the DUT). Very accurate even for HF AC when well and evenly isolated, albeit slow.

Nope! It is measuring REAL, or "TRUE" power: P [W] = R.I^2. It is the REACTIVE and the APPARENT ones we don't get by the calorimetric methode you have well described (thanks).

13) A straight filament incandescent light bulb enclosed in a dark box with a temperature-independent light sensor. Suffers from impedance mismatches - especially when not used as a sole dummy load to measure OUTPUT power.

I never stated that the opinions of the members of this forum are ludicrous.
I stated that:After all, an OU forum is by definition about power and energy !

Frankly, I am surprised by the amount of resistance I am getting to the proposition of accurate measurement of the key magnitudes that are the very subject matter of this entire forum.

I welll aware you probably don't care but I am 100 % with you on this evaluation of the scene and importance of accurate measuremnts, would be as cheap and simple than the calorimetric methode, and probably your W->V convertor as I could understand what you say about.
