Kapanadze Cousin - DALLY FREE ENERGY

[NickZ]

   Verpies:
   Although your comments as to our members opinions being ludicrous is a bit over-rated, if not offensive. Please explain why you don't SHOW us all how this power meter would help, when our eyes can clearly see that we are all a very long ways away from achieving OU. Nor is a light box needed as well, until we reach that point where the difference is so slight, that such a box, or metering would be of benefit.
Or are you still having "technical issues".  No offense intended.

a.king21 is right.  A method for reliably dump the excess energy is required.If you watch Kapanadze aquarium video the smoke is just because the protection circuit was not good enough....

Only place I found mention of resonant-rise : http://adammunich.com/zvs-driver/
ahh; and here... http://digitalcommons.calpoly.edu/cgi/viewcontent.cgi?article=1266&context=theses


but ya, that's the increase in stored power in that circuit... so your mosfets must withstand the target voltage, but so must the diodes; if you use 1N4002(100V) or 1N4003 (200V) if you have a 10X storage increase, then if you use 80V you need to use at least a 1N4006 (800V) but that will be only marginal.

Other than having to make sure your levee has a high enough containing wall... I don't see an issue with 'resonant rise'... ?

In English, you may find more references to it as VRSWR: Voltage Rise from Standing Wave Resonance. I myself have referred to it several times on this forum alone. It is why a properly constructed Tesla coil can attain such high voltages at the secondary, much more than simple turns-ratio transformer action alone would allow. It is also the cause of many blown components, as you note.

I and others see it like this:


EVERY experiment we do is looped.


That's why I don't post failures.
So the issue of an accurate power meter is academic.
I have a simple method of testing how near or far I am from OU.
Everything is powered by a battery.
Then I periodically switch the circuit off and check the battery voltage.
The only experiment which succeeded was the Carlos Benitez 4 battery experiment.
After 1 week of continuous use, the battery voltages were the same.


But if you develop an accurate power measurement meter, then good luck.
You remind me of the US in space. They spent millions of dollars developing a pen which
worked in space.
The Russians used a pencil.
Just my 2 cents worth - no offence intended.

I am with you about using the simplest and cheapest way, but as Verpies' meter looks very cheap and simple he said, but accurate, it should tell in real time just for few bugs if the experimenter goes in the right direction or not (even if speed rising temperatures test in dry boxes would say for even cheaper,  not so fast than Verpies' meter but much faster than the battery checking  which is relevant too).
I do think the systematic use of his meter would be very very huge progress here.

After 1 week of continuous use, the battery voltages were the same.

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

The Russians used a pencil.

A DMM is more costly and complicated than the W-->V converter, yet you use it every day.  A scope is even more...

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.
8)   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
11) Treating the open circuit battery voltage as on indication of its energy content.

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.
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.
