Optimal tube Size Query
« on: July 16, 2008, 05:07:47 am »
I've been experimenting with .75" outer tubes and .5" inner tubes with .065" thickness.  My gap is 1.5 mm  and I like this gap very much.  It's a very active gap for tap water.

I was just thinking that if you could get wider tubes and maintain the 1.5 mm gap that you'd have a larger surface area and not need to have as many tubes.  I like the 5.5" length Riddler uses.  My 1992 car doesn't have room for a large 24" cell.  Thanks for any suggestions you may have.  I do know that the more tube sets you incorporate into your cell the more resistance you have and that is probably an important thing.  So, fewer tube sets may not be a good idea.

i think you do know what your talking about when you used the word resistance, just to make sure...

The more tubes you got the LOWER the resistance will fall, eventually leading to a DEAD SHORT, not to mention the use of additives will cause a DEAD SHORT when using tube cells.

Each single cell is around 8 to 15 ohms, when you place 9 or more of these cells in parallel the ohms drop, usually we would use a mathematical formula to calculate the resistance once all the tubes are connected together, however this does not work.

One single tube may be anywhere from 8 to 15 ohms, but when you add 8 more your resistance is then depended upon the power source and can not be calculated. For example.

My 6 inch tube, a 12 volt car battery, it pulls 1.5 amps or so... so that is 8 ohms,, But wait, if i put this same tube on the alternator, it may draw 58 volts at 7 amps, again 8.2 ohms.
Now i add 11 more tubes to this on the alternator, i use 35 amps 25 volts, ("0.7") ohms, See that effect? see how this altered the ohms. now you know 0.7 ohms total  your tubes is with the alternator. so now reverse it, ohms * tubes = single ohms.  0.7 * 12 tubes = 8.4 ohms per tube, i think i just proved myself wrong, never seen it workout that way, hrmmm. nevermind this paragraphe lol, its right though. its rare for them numbers to work out the way i just worked them.

the point is when you put more tubes in parallel your resistance drops becoming closer to conductance, the lower the resistance the more gas is being produced, i once thought stans resistance was 0.3125 ohms total because of the way he chose to word his test of evaluation, but i later learned his trickory in wording, the 12.5 volts he talks about in that test is not the voltage across the cell, i assume the voltage across his cell was about 21 volts min, by 40 amps. thats 0.5 to 0.6 ohms i think stan was running at.

About the tubes, smaller OD tubes will clog up with hydroxy, and hydroxy is whats causing the resistance of amps. When you first power the tube up it will eat amps and conduct until it breaks the water apart, when the water is broker it will clogg the tube with hydroxy, the non conductive type and this will take mass storage causing no water to be in its place, this is where the resistance takes place and how it works. So a longer tube with more hydroxy will resist more current if the tube is small in od, a bigger tube in od the same length will resist less since it is bigger, so the smaller tube has the most amp restriction. The hydroxy cant really fill the 1 inch tube that well "all the way around"  because of its mass size, this is why i believe stan chose the 3/4 inch tubing.

but yes, an active gap is a gap thats conducting, people say water is a pour conductor but they're not fuel cell wizards, with a gap that small water is a great conductor if you know how to force amps into the gap, and coils does just that. maybe you can understand a little better now about using a larger surface area, understand that with that area you also need hydroxy coverage, and can you get it?

its easy to confuse resistance, the more the resistance the less the conductance, if you resist to much, there will be no connection to make possible.
the lower the resistance, the more current will flow, eventually if the resistance is to low you will result in a dead short, and with tubes you should not use additives or thats just what you'll get since the gap already makes water conduct so great.

to someone watching this thread that would like to learn something, if your good with math go reverse engineer page 60 of stans test of evaluation report. thats where the key is.

Hi Riddler,

Thanks for all the great information.  I'm new to electronics and was speaking about resistence from 3rd hand knowledge, so I may likely not understand it properly.

Thanks very much for giving me some guidance.

Very educational  post indeed!

Riddler

Is the report you are referring to with the secret on page 60,  Water Fuel Cell International Independent Test-Evaluation Report?  Thanks for the heads up!!
