Well I have used the distilled water and?.

No more brown crap floating around the plates Now that is a plus.

Before I added any baking soda I got less then an amp drain (.60) Good.

 But then it got me thinking this system may have been better? Why

Well first I had a Positive negative arrangement for 11 plates (5positive and 6negative) with negative on the outside. Problem was I had 19amp cold with no baking soda  using tap water. I kick myself now for not trying the distilled water to find out where I would have been. Before I tore it apart and cut down on the positive plates.

Oh well?. Lesson learned

 RTS WELL the good side is you won't do that again   please keep posting your results and questions thanx  Chet PS if you could hold off on the computer control device for a while it would be good

Re: More Update Simple PWM

So here is what I have. THis thing is power hungry. Any thoughts?

I used distilled water/bking soda cold 9amps light hho production. As it warms up more and more production. Also more and more amps. I just blew another 30amp fuse on the way to work.

So should I boil the distilled water first. Get it hot. then add baking soda to get to 15-20amps? Will it stop there?

Would a heater work in conjuction with the HHO cell?

boil distilled water?
     heating it to the cells max temp and adding electrolyte is fine but it will take ages to get your cell that hot in the car. since itll start at just a couple amp. sure seems like electronic regulation would make more sense here.

Ok I may have it under control.

Boil it to get the cell hot then set the electrolyte this way the system is hot already. But I think I may have got this under control It seems 18miles to work pops the fuse. I emptied the cell and diluted it a bit. I may be at 20amp now hot. Not 100% sure since the meter shuts off after 18amps (too much)

But I still need more help with this so I added a new post about this topic.

My next idea for the heat problem was to extend the fins of my cell outward of the unit, and use the existing car's cooling system to keep the cell cool.  This would make the cell heat faster, and keep it at a maintained temp.  Problem arises in how to build the cell to maintain 165degrees f.  acrylic sure wouldn't do, and ideally I would need it to handle 195, so I can use it in my other vehicles as well.

oh, and dump the baking soda and get some KoH.  It is cheap and relatively safe when the proper safety is observed.  I switched to KoH and will never go back.  My plates that used soda are starting to show signs of rust oxidation on them.  the ones that have only seen KoH are not showing that.  they are a dull grey on one side and a darker almost black on the other.  Each cell is that was I assume showing the current flow thru the system, in other words if I was to use pos in the middle and branch out to neg, I would expect the center electrode to be the same color on each side...

Yes but where to get the KoH local. You are in FL so where do you get it?

I ordered it from www.summerbeemeadow.com  Comes in a plastic container with black electrical tape to help keep it closed and air tight. 


Keep in mind this stuff is very very reactive.  Put a flake in a glass dish and you watch it pull the moiture out of the air unbelievably quick.  Get even a weak solution on your skin and it will feel sorta slimey and if you rinse it off immediately you may notice your skin to be rough where it contacted it.  Always wear long sleeve clothes, long pants and face and hand protection when working with this stuff.  I also work with it in a temp controlled enviroment to keep as much moisture out of the air as I can.  I also keep a spray bottle of vinegar on hand and spray my cell with it and then rinse with clean water when I am done.  With proper precautions this stuff isn't bad to work with, but if you are a sloppy messy person then you may want to have someone mix the solution for you.

Also always mix the flakes into water and not water into the flakes.  Also stir or swirl constantly.  KoH produces a large amount of heat instantly when added to water.  I could see where someone could have big problems mixing this stuff backwards.  As for how to measure the concentration I am not sure since one is flakes and one is liquid.  What I did was mix a somewhat stron solution and dilute it down to where I wanted it to be.  My cell holds bery little water so I started with a milk just about quarter of the way full. I ended up with a hald a jug by the time I was done.  This worked out good for me as I conditioned my cell a bit different the when I used sodium Bicarbonate.  I ran the cell in a strong solution for a few days then a weaker one and now I alternate a weak one and straight distilled water.  I have to pull the cells apart soon to inspect the plates but the last time I did they lookd pretty good. I am going to flush it one more time then I am going to run it at a weak solution for an extended time to see if or how much the output decreases.

wouldnt a pwm installed in the car, tuned off in the begining and then turned to pulse after cell has heated up be the trick? that what im kind of hopeing to do..... maybe put it on a timer? or a elecrtonic temp gauge and once it gets to a certain degree kick on the pwm to have less current to produce heat but since you get more production from hot water this would balance it out maybe.... what do youall think?

circulate the solution
« Reply #41 on: April 17, 2008, 05:12:44 PM »
i have a unit from super hydro 2, it uses a natural circulation to cool the fluid. i dont know if you use smacks like this, but you should be able to. do a youtube search on hydro super 2 and watch his videos. i think this might be the best design with bubbler, circulation. i think combined with smacks output, it might be a great unit....

Ok now what about a regulator or PWM to stop the excessive drain.


This is the pwm i use in my hho setup. I bought it here http://www.extremehho.com . I have noticed the excessive heat at the terminals is now gone and it can finally control it. The built in amp gauge is what sold me on this one.
My next step is to hook up a temp gauge for my cell and i also plan on buying a Scangauge II.

If you don't want to build your own you can buy a nice one at http://www.extremehho.com
