Title: Testin phase
Post by: sebaw on September 07, 2007, 03:22:19 PM
Hi guys,

I am not new on this forum, i just don't post much. Been reading your stuff for over a year now.

This is how far I got, http://www.youtube.com/watch?v=Tmitm_pbY9w

You can see the cables burning in the background, but that's due to their thickness. I am using distilled water with about 5% KOH (by weight).

Don't know about amps or voltage across a single cell yet, though i am running it of a 12V car battery. (Only 6 out of 30 cells connected, there are 24 total in video, 6 are missing didn't put them in just yet)

Outside pipes are 17 cm long and the inner ones are 18, 1cm is left at the bottom for easyer water displacement and the spacing between the pipes is 1,5mm.

I'll have some more pics and info on it in a week or so, waiting for some cables and stuff...

Sorry for my english, I am from Slovenia...

Take care,
SeBaW

why are you using electrolite? condition the cells and you won't need any and your tubes will last longer....

Looks very promising, and your english, if you would not have said anything I would not have known it wasn't a first language. I look forwardto more.

some pics of the cell, or maybe i should say cells...

outside tube: thickness = 1.5mm , diameter = 16mm  , length = 170mm
inner tube: thickness = 1.5mm , diameter = 10mm  , length = 180mm

gap between tubes = 1.5mm
...

electrolyte:  5% KOH , 95% Distilled water

@Duranza: Don't want to use tap water, to dirty  ;)  am staying with distilled and KOH

Acrylic, with pvc gasket and a pressure meter up to 6 bars, bolted together for easyer maintenance...

but i guess more than 10 psi won't be necessary or wanted, i feel more like putting the thing under some vaccum and see what happens...

Holds about 7,5 liters of electrolyte when empty...

well lets just say that i'm using distilled water and i get the same amount of gas without electrolyte after conditioning my tubes.

Nice cell case btw!!!   :o why didn't you just used crazy glue for the bottom and sides?

well, it seemed easyer to do it this way...

can you explain the conditioning process to me and are you using VIC or something else to run your cell? I will be running it on 12V straight from the batteries, many amps i guess but 2v per cell.... am thinking of pulling about 100-150 A at 2 V..... 200-300W

i will try and build a VIC or a pwm of some kind in the future...

You can follow Ravz way to condition them, but RunningBare and I have come to find  a faster way with slow pulses 12v @ 300ma- 500ma. Change the water every 20 to 30 mins and let the tubes dry completely for the oxide layer to form. I just put mine in front of a fan to dry. Runningbare puts his by the door of an oven. The point is to let the oxide layer form. I guess if you have a compressor you can blow them dry... Whatever works...

@ sebaw,

Very nice looking unit you have there.

May it perform even better than you could have hoped for.

Beautifully built sebaw,

Best of luck with your experiments.

@JamesThomas and hansvonlieven: thank you very much for you kind wishes, tommorrow i am gonna try lighting a flame fot the first time...

hansvonlieven: i read your page about Keely, nicely done, i admire the work of keely and haven't seen better explanations of his devices then yours...

keep up the good work

G'day sebaw,

Just received this in the mail (I am on their mailing list) I thought this would interest you.

Theres something wrong wit d dimensions you mentioned

outside tube: thickness = 1.5mm , diameter = 16mmÃ,  , length = 170mm
inner tube: thickness = 1.5mm , diameter = 13mmÃ,  , length = 180mm

gap between tubes = 1.5mm



Outer dia> 16mm - (1.5 + 1.5) mm thickness = 13mm inner dia of outer tube!
Your inner tube dia is 13 mm>>>>there shoulnt b a gap in between d pipes at all!! Actually if dats the case you cant put 1 pipe inside another!

It looks like u have around 2 to 3 mm gap b/w pipes for the pics.

Check ur dimensions again. :o

If d outer dia of inner tube is 1/2 inch  >> 12.7 mm then 1.5 mm gap is correct. Check d thickness of outer pipe for correct gap.

thickness>>

14 AWG = 1.626mm   15 AWG = 1.448mm   16 AWG = 1.295mm

16 SWG = 1.626mm   17 SWG = 1.422mm   18 SWG = 1.219mm

@sebaw
Well done !
Please be safe and use at least one or 2 bubblers after the electrolyser when you try out a flame
from your electrolyser.
Please keep us updated.
Many thanks.
Regards, Stefan.

@Gheller: You are right, the inner tube diammeter is 10mm... I shall make corrections in my post... Thanks alot

@Stefan: Thanks, i sure will use bubblers....

some more info in the next few days....

@sebaw

Where did you get your tubes from ?

@sebaw

Where did you get your tubes from ?



Searched the "net" for SS suppliers in Slovenia, came to the conclusion that INOX Center from Gorica was the fastest way, btw the tubes are SS304...

Where are you from ?
