The research I did may still help others so I'll leave the site up, but my interests have taken me permanently away from HHO. Visit my YouTube channel at Download my latest HHO files at:

7.00 mmw and above?

Recently several HHO researchers have broken through the 7.00 mmw mark. It’s an inspiration for those of us who are still producing HHO at around 5.50 mmw. Even though no one has come forward to reveal their precious knowledge I think we need to be grateful that they have shown the possibility. How many variables can there be? Seriously if you can think of something I’ve missed, please comment.

Plate spacing
Surface prep
Leakage (holes in a dry cell and edges in a wet cell)
Type of stainless steel
Running temperature
Wire size

Sorry I can’t think of any thing else. Visit my Playlist of over 7 mmw videos.

What is it that these people have done right? How far can we go?

I love the smell of HHO in the morning


  1. I believe pressure is a factor as well.

  2. I just noticed you're in Chico, CA .. I'm actually living here too. Good to guys experimenting with hho, locally.

    If you need any 304 SS sheets let me know, I have a several 48" x 5" strips I'll sell for cheap, you can reach me at greg (at) norcal-solar .com

  3. Hi Greg,

    Since there is no intended pressure except the gas trying to escape the generator, I'm guessing you would favor a large tube and connection to the electrolyzer. Would you favor an increase in plate separation too? I'm currently testing a dry cell with only 6 mill gaskets.

  4. Greg I took a look at

    There is a lot to read there but I now understand what you were saying about pressure. Thanks for directing me to such an extensive collection of information. It was worth the time it took to read through and look at the various links.

  5. The biggest one is current density and how it applies to cells. recently I saw a nine plate cell making 4 liters per minute off 12 volts 40 amperes the reason the guy could do his math on the current density per centimeter of plate space

  6. Anonomous,
    Sorry I don't understand what your point is.

  7. well Mr Bob
    from my humble knowledge about electricity I think that as thick as the plate will be more resistance will accrue and that means more loss of current
    plus the type of the metal, I know that Copper and Aluminum has less resistance to electric current
    so why don't we use aluminum foils instead of SS316 or SS304?

    secondly the area of each plate when we apply current on the plate the current will be the highest near the source (just like when you heat the plate) so if we can make more than one source to the same plate from the same polar charge (positive or negative) or we can make the plates smaller and double or triple the numbers of the plates it might work also.

  8. Ahmed,

    HHO is dead to me, but I can't help but point out your inverse concept of electricity. Thin = higher resistance not lower.

    Aluminum? I don't think you have experienced the effects of NaOH and aluminum?

  9. yes you right about the the resistance but what i meant i meant is as thick as the plate as more as the rotating current (Eddy currents) will appear more that means more heat and more heat i believe it means more current loss ( that is why they make the current inverters from too many layers of isolated plates and the wire cables from multiple wires).

    so there should be a standard thickness that makes less Eddy currents and to have good resistance.

    no i didn't experienced the effects of NaOH and aluminum, I'm not good in chemistry.

    i understand you stop interesting with HHO but actually you made good blog about.

    i will realy appreciate your advice.

    i was thinking about making calculation based on all variables ( plates area , plates thickness , NaOH percentage , Plate spacing... etc. ) by comparing the others experiments pu it on data sheet and i think we can get to reach the best design

  10. What we really need is an electrolysis chemical calculator. Where we can put in the metal electrode types for anode and cathode, and the electrolyte. Then it would pop out the results of the items being produced to include gasses, and compounds that might be nasty. These nasties include Chlorine gas, Methane which produces Carbon monoxide when burned, gaseous nickel which is poisonous, and Carbon monoxide, and dioxide which can displace oxygen. What goes into a cell is as important as what comes out.
