Meyer's Resonant Charging Circuit Analysed

[Farrah Day]

Some more thoughts for you guys to mull over.

When pulsing a square wave, unlike a sinewave where the voltage rises gradually, the square wave voltage is almost instantly at maximum. Now, across the resonant charging cct inductor, the voltage is 90 degrees out of phase with the current through it - the voltage leads, the current follows.  Now, if the tiny little fast moving electrons can't keep up with the voltage, the relatively massive bulky ion impurities in the tap water certainly will not be able to do so.

Therefore we have a voltage across our wfc before the electrons get there, and well before the ions get there. As this goes on, charges are accumulating on the electrodes, waiting to exchange charges with the ions in the water, but... the electons at the cathode (and +ve holes at the anode) will be gathering far more quickly than the ions. A bottle neck forms and the charges on the electrodes continue to accumulate until massive dielectric breakdown occurs.  At this stage, rapid ionisation of the water occurs and we get lots of gas, but as there is such an excess of charges on the electrodes, that no great surge of current through the electrical cct will occur.  We are simply using up these charges, while the rest of the electrical cct carrys on the charging process.  It will be important that the charges on the electrodes are not totally depleted, or else this would cause heavy current to be drawn through the electrical cct. 

Hence, unlike normal dc electrolysis, the electrodes have an excess of stored charges, which can effectively be used before current is required to flow through the electrical cct. That is why a pulsed cct only draws a low current through the cct. 

Here's an analogy:

Think of dc electrolysis as your house mains cold water supply running through to your kitchen tap. If you turn on the tap, that water mains pressure forces the water out. If however, you turn off the mains water supply at the stopcock, then no water flows when you turn on the tap.

Now think of pulsed electrolysis as your house hot water supply, where you have a storage (header) tank in the loft. Mains cold water is used to fill up the loft storage tank - like charging up a capacitor. Now again, you turn off your mains water at the stopcock, so no water can flow from in the cold water circuit. However, when you turn on your hot water tap and it will flow, and continue to flow until the storage tank empties, and during this time it requires no cold water supply, i.e, thanks to the storage tank, the hot water can flow for a time without drawing on the cold water.

Think of the voltage as the mains cold water pressure, the hot water storage tank as our 'water capacitor' and the hot water running with the mains cold water turned off as the exchange of charges between the ions and the electrodes.

Now, here is my thinking behind the signal pulses and components of the resonant charging cct.

Firstly, the main frequency pulse. We will want this to be quite high, as high frequency through an inductor will create a high resistance to current flow - hence the inductor acts as our natural current limiter.  Note: I'm dismissing all ideas of resistive wire to restrict current, as this would simply waste power, whereas an inductor will store energy and release it back into the cct with only a very small loss of power.

The modulation of the high frequency pulses. Now I've heard mention that this is used to control the gas output in order to accelerate/decelerate a vehicle. However, I don't think we have that to worry about yet. So I believe that more likely the modulation of the high frequency by a lower frequency is what provides the 'off' time that allows the dielectric to reform.

I emphasise that this is only my personal theory of operation, but to date, as far as I can tell it's the only one that has been put forward that offers any kind of scientific explanation to go along with it.

Feel free to respond with your thoughts.

Hey FD,
Just letting you (all here) know I am reading, need time to assimilate, ...and very grateful for these posts. 
Breifly, I initially find this analogy provocative.  If the logic holds, I wonder what that might indicate regarding cell tuning.

I expect I will not be able to participate for a spell... major business deadlines to attend to.  But be assured I will be following.

I hope some electronics and chemical geniuses show up to theorize and comment ;^)

Cheers,
HTH

Hi Tao

I am looking at this thread, with interest, with the thoughts back a few posts,
You were going into the acoustic effects it so happens I have been looking at this for some time, since you can not have electrical resonance in a DC circuit, but acoustic resonance of the tube could play a big part.
Now sound travel in water is called 'wave' and this is1600m per sec NOT 1435.
When you were working on the tube resonant frequency there was a few things not taken in to the calculations.
You need the thickness, and the length, and the free resonant frequency of the material.
Now if there are any fixture points or any thing else other than fresh water this will change.
In my opinion the only way to fine the F under water with any connection of any type made, is to do the test in its own environment.
Using a transducer such as an echo sounder, should be easily obtained if you go fishing, 'borrow it' from the boat.
You will need some thing a little more technical for the next bit.
You need two 'strain gauge' transmitters; these are special resistance strips, one for the vertical and one for the horizontal.
Fixed to the pipe in the centre, as described, a small voltage is applied and the voltage across each of the strain gauges is monitored on the Scope.
  Using a sine wave generator connected to the transducer, sweep the frequency ranges close to you 'rough' calculation.
You will see the effects of any increased vibration changes on the strain gauges.
I am hoping to check this out later on my self. 
Even when you find this frequency all the tubes need to be tuned to the same frequency.
Now you will then need to use a transducer at that frequency in the cell, you will not be able to do this through the electrical circuit connected to the cell circuit.

I think reactance in the cell is the word everyone is looking for. Do you think water will act as a dielectric? only if the water is scientifically pure, pure water doesn't conduct. A dielectric is an insulation.

[Farrah Day]

That was short and sweet Rab.

No, 'reactance' is not particularly the word I'm looking for.

If you read through my various posts you'd see that I don't think that water is the dielectric, I think it is the chromuim rich oxide layer on the ss.   That said, tap water, not being the greatest of conductors, will likely allow a build up of charges on the plates as the large slow moving ions can't move through the water fast enough to deplete them all in one go during pulsing.
