when we're talking about resonance I think we're talking about
the physical resonance as in a bell or wind chime, I'm going to use
1" and 4/3" tubes same as Dave. The only variable that can't be changed
after the cell is built is the length of the tubes, you can vary the frequncy and
the gating you hit the tube with this frequency. I think the 2 tubes have to resonate
the same frequency so according to these wind chime frequency tables

http://home.fuse.net/engineering/1alumnium.htm

http://home.fuse.net/engineering/34alumnium.htm

the 3/4 inch tube should be shorter than the 1" which doesn't make sense.
I'm looking at about 5" tube length which gives a third overtone frequency
of 38.016Khz. By the way I'm making all this up as I go along so I'm not
sure wether it makes the slightest bit of difference, but it's worth looking into.
It says on the home page aluminium and steel have similar acoustic properties.

Ravi,

Do you know the approximate frequency at which you are applying the square wave pulses to your WFC?



The reason why is related to some research I did with a well known 'water as a fuel' research group.....


Here was the crux of my interesting finding:

The findings are based on this youtube video from Dave Lawton: http://www.youtube.com/watch?v=miwbvsya3Ek , WATCH IT!

Just doing a simple calculation a tube in plain fresh water, the equation from http://en.wikipedia.org/wiki/Acoustic_resonance shows f=(n*v)/(2*L) where n corresponds to the harmonic, v is the speed of sound in the water, and L is the length of the tube....

So, lets simplify this equation, n can be always 1, v is 1435 m/s in fresh water according to Wikipedia.

So, f = (1*1435)/(2*L) = 717.5 / L = f , Just for fun, lets take the frequency Dave was producing Hydroxy at in his latest video on Youtube: 3425.781Hz

So, 3425.781 = 717.5 / L , L = 717.5 / 3425.781 = 0.21 meters , So that would be 8.27 inches long.... So, how long in inches are Dave's tubes? Just curious........


[4/2/2007 11:26:20 PM] Tao says:
So, I asked how long Dave's tubes were, well, I looked up how long they were from an old post Dave did on the original forum back in 2004...


[4/2/2007 11:26:44 PM] Tao says:
Dave said that his tubes were about 12.5-13cm (which is about 5 inches long)


[4/2/2007 11:27:39 PM] Tao says:
so, calculating that into the equation: 717.5 / L = f , we have 717.5 / 0.1275 = f , so f = about 5650Hz


[4/2/2007 11:28:21 PM] Tao says:
So, based on what it says at the END of that video on youtube, it says that the hydroxy was being produced at 3425.78Hz


[4/2/2007 11:29:00 PM] Tao says:
BUT, they acoustic frequency came out to be 5650Hz, so I said, 'oh, too bad' seems there isn't much of a connection, I guess I need to
do more research'


[4/2/2007 11:29:10 PM] Tao says:
UNTIL, I just watched that video again..........


[4/2/2007 11:29:50 PM] Tao says:
Look at what Dave was pulsing his DC at in the video: 5714Hz!!!!
At 1:11 in the video you can see what he was pulsing at.......


[4/2/2007 11:30:58 PM] Tao says:
Based on the equation for acoustic resonance, Dave was pulsing his tubes at the EXACT frequency at which those tubes will resonate ACOUSTICALLY in FRESH WATER...



So, my finding was basically this:

Dave found the BEST gas production at the VERY SAME frequency that just so happens to be where his tubes resonate ACOUSTICALLY IN WATER... HMMM...

Maybe it is nothing at all but a coincidence, but maybe there is just something to it........................

@runningbare

somewhere i read that each time you add a tube, the cost in watts is less for each additional tube. i think it was in the d14. in your last vid i only saw one tube, but it seems like most of the uber bubble vids have 5 or 6 tubes. i dont know if you figured that in or not. im nowhere near as knowledgable with whats going on as others; just trying help out some way. but a diminishing cost with a linear gain could be significant with your glove test.

Hola TAO
En relaci?n a la determinaci?n de la frecuencia que viene dada por el largo de los cilindros, y en tanto no se termine por conocer en detalle la operaci?n del sistema de Stanley Meyer, sugiero tambi?n considerar como alternativa a la velocidad  del sonido en el agua (1.600 m/seg), la velocidad de propagaci?n del sonido en el acero ( 5.100 m/seg).

D14 updated      page 8     paragraph 4.
dis info was always there right from d 1st D14!!

You generation looks 12V 300 / 400mA.   Anywhere close??

Thanks for d update mate!
