LtCFisher's Cell

[Bob]

There is a bunch of people asking me questions about LtCFishers cell, the tube cell that he made that worked so well, and Unfortionately I am at just as big a loss to explain it myself
simply because I don't have enough information on what it was that he made <GRIN>
 With LtCFisher here with us perhaps we can discover what makes his cell work so well
Personally I think its the Power that he was useing to run the cell... but thats just my opinion... I don't know that for a fact...
However This man has been constantly experimenting while the rest of us just type so give him a break and the benifit of the doubt.... before you deside that "there ain't no way!"
 He has presented on the other forum pictures and schmatics and is no doubt a asset to us in our search for knowledge about this stuff...
Here is a Pic of My first...and last Tube cell...so you can see why it didn't work very well at all ! <GRINI>

LtFisher,

If you are reading this,  it would be a great help were you to also copy the info you posted over on the generator site here.

Bob,

If he would post more info then maybe we could get to the bottom of the massive power draw that fried his supply.

Could you point me to the wiring diagrams.

Havn't been there in a week...sorry I got my hands full here its under the thred "Makeing too much Hydrogen" I think... but not positive.

Hello, everyone.

Thanks Bob for the support.
I will be posting here, the power supply I was using was one I built. The drawing is posted on you tube and was sent to all that requested it. It the power supply was a unfiltered dc voltage with 2 braking resistors. I think I can walk you through it. The Design: input was to a variable transformer (0-120 volt) output was to 2 stacked 40 full bridged rectifiers, from there plus went to the resistor bank and negative went to it's output terminal. After that it was connected to the tube cell plus to plus, neg. to neg.. The tubes where stainless steel set at .125" clearance. You allready know the tubes were perforated .250" dia.. postive side was a .500" sst strap, neg. side 1/4-20 sst. allthread rod attached to the bottom of the neg. tube by means of a 1/2" round bar centered in the tube and welded in place with silver. All my sst. welding is done this way using 15-35% silver, no oxidation and not responsive to tempature changes. I will start building the next generation cell some time after the holidays as my wife is using up the funds faster then me. LOL. I was going to try a half wave power source un filtered similar to a battery charger design I have some old 100amp diodes laying arround and they are eager to go to work. LOL. The other project I am working on is to split the DC power source into 3 (yes 3) different positive legs and a common negative from one power source. Making one pos. leg half wave and the other two full. I think this will boost gass productio to new levels.           (old man rambling again)

Great to hear from you again.

Ahhh Kool Thanks LTCFISHER !
good to see ya made it over here
...
I tried to post a pic of yours here only do discover the pictures were HUDGE ! I mean like WALL PAPER size ! 2280x2010 or something like that...so I re-sampled it and made it smaller 800x600 pixels in size ....
so here it is ...
Bob...

[Bob]

I'ed realy like to see the bottom of that cell Fisher....
do you have a pic of it laying down ?
...
I set this forum to handle a single 1024x768 picture in size ( thats big) but I figure most people will post 800x600 pictures so I think you can post 2 or 3 of them at a single post.
if you have truble re-scaleing the pictures just email them to me the way they are and I'll re-sample them to 800x600 for you and post them...
I use Corell draw to re sample the pictures, there are all kinds of utility programs out there to change the size of the photo's ...
but it realy makes sense to change the settings in the CAMARA first !!!!!!  you realy don't need pictures that big... I set my camara to 1024x768 and it works great for me , plunty of detail and not so big as to eat up the camara's memory.... I can get 32 pics in my camara by useing that setting,.... many more if I set it to 800x600 but the resoultion dropps off a bit!
...
Hope that helps... the camara can make the pictures the right size for you if you set it for it!
...how you do that is diferent with each camara ! HAHAHAHA !
good luck on that !
...
hope that helps !

LTCFISHER: Do you have a Pic of your 30 switch plate design ?
I'ed realy like to see that thing... I have a gutt feeling thats the one that will get us 10 to 15 LPM
without too much truble.
and it should be fairly small in size makeing it fit-able under the hood !
...
Thank ya !

Can't get my head around this one.  How do you propose connecting this to your hydroxy cell >

A quick diagram would help a lot.

P.S.  I'm ex radio ham and also (dropped -out) ex electronic degree course student (years ago) ,  So don't worry about using tech terms on me.

I am a newby to all this so do not take any of my input as hard fact, just uninformed obervations.

I have built a close version of the Fisher cell and am in the process of seasoning it now. I have seen a few plate designs so I have a little info for comparison. The Fisher tube design is producing more gas than any plate design I have seen. I am only putting 2 to 3 amps into it and getting a fair amount of gas (have not measured it yet). I get a very small amount of gas with straight distilled water and it only takes a pinch of sodium hydroxide to get the amps up to 3. I have this in a 4" X 11" pvc pipe  and with a dip of sodium hydroxide the size of a kitchen match head I will get 8 amps and a very noticeable increase in gas.
All of this is powered by a 6 amp battery charger. I am noticing that if I go more than 3 amps I start getting heat and building the black stuff on the negative side.

As I said above this is new to me but from what I have read I believe I am putting way too many volts into it so I am looking into a way to lower the voltage and at the same time trying to figure the best way to add more cells which I believe will use the excess voltage and increase production.

This is addicting and in some ways as frustrating as raising kids.

Any suggestions will be appreciated,

oldntrd,

Sounds promising.  So your not using any resonant devices,  just straight DC ?

Can you give me more exact dimensions.  I need to build this as an exact replica of yours to compare results.

I have just started doing some very basic tests on plate designs  See my posts.

re,
...Any suggestions will be appreciated,...

Just one,  measure the gas.


Manta

[Bob]

Yes sounds incurrageing indeed !
but without a good measurement we have nothing gained but it makes bubbles ! HAHAHAHAH
...
get away from the Sodium ! thats what is giveing you the black stuff.... you are trying to make a ton of green goo... but trying not to make it by not useing the amps.... HEHEHEHE your fighting yourself
use lemonaid Koolaid!
...
can you please post your Dimentions of the cell???
PURDY PLEASE <GRIN> ehheheheheh
...
Bob...
 

[Bob]

As far as the voltage goes according to what I have read "a Cell only needs 1.25 vdc to operate and all the rest of the voltage goes to make heat",
 ( Personally I doubt the last part of that but thats besides the point!)
so yes if your useing 12vdc then you have more voltage than you need... but so do we ALL
and its not that big of a deal.... as it will operate on that voltage for quite some time before getting too hot....or SHOULD ! <GRIN>
...
from the sounds of things LTCFisher made his plate spaceing very close for a tube cell...
and from my experience close plates mean better output !
...
I can't wait to get more info on this cell ... its realy got me thinking ! HAHAHAHA
...
Bob.......

[oldntrd]

You are right on the black goo. My wife went to the store today and I asked her to pick up some lemon kool aid without sugar but she said all they had was with sugar or substitude so she did not get any. Will the one with sugar work?

I do not have the specks on my cell with me but I can remember most of them. They came from the other site and were posted by LTC Fisher. I think the only change was the ss and that was because I just happened to have a piece laying around and I was itching to get started learning the basics.

Metal is 304 perforated ss, 1/16" perforations, 0.033 or 0.035 thick from McMaster Carr

Both tubes are 7.25" tall

Material was cut: inner, 7 1/4" X 7 5/8" 
                        outer, 7 1/4" X 8 5/8"

Joints were butt soldered with silver soldered  *I do not like this and if I do it again I am going to do a 1/8" lap joint

The finished inner tube will be 2.4? dia and I cannot remember the finished dia for the outer. The gap will be a little less than 5/32"

I have a "U" shaped piece of ss slipped up inside the inner tube from the bottom and silvered to the insides of the tube. This is drilled at the center of the base of the "U" and the all thread rod shown in the picture is inserted in this and double nutted to it. The upper end of the rod just goes up, makes a 90 and out the side of the pvc.

The outer has a ss strap silvered to the outside of it near the base and runs upward to about 1 1/2" higher than the tubes where a bolt is silvered to it and the bolt goes outside thru the pvc.

I do intend to get some measurements very soon but right now I am trying to get thru the black goo stage and I cannot find my pipe tap so I can instal the fittings and screw on the cap. I tried two stores and ran out of time to look further.

My results so far are not anywhere near those LTC Fisher got but still better than any of the few I have seen. It is running 24/7 now at 3 to 4 amps and I dump and wash once a day. It was about 1 1/2" above the cells when I checked it this morning. My wife called about 2 this afternoon to tell me it was halfway down on the tubes so it used roughly a quart of water in about 8 hours at a little less than 4 amps.

At this point I am impressed but not real impressed. It is going to take more. As soon as I get the bugs out of the basics I will add a pwm and ?

Oldntrd:

You realy Need KOH with that cell.... and I doubt that Lemonaid Koolaid (Unsweetened!) will do ya
(never use the sweetened stuff !)
...
you can try Vinegar if you've no KOH or lemonaid... its not very strong though...
...
thank you for the explination and dimentions I appreaciate it very much....
I think I remember Fisher saying his Tubes were closer togater than 5/32" but not positive
and that could change the output a great deal.
....
if your going through water that fast it must realy be bubbleing like crazy ! I could run my bank of 3 Randy cells all day and use only 2 cups of water at the most ! HAHAHAHHA
....
so basically, you rolled your own tubes, got a close fit and soldered them up and thats what ya got !
...I sure wish you had some LPM measurements for us ....
hehehehe
