  • Hi Careica. A couple of things about effeciency. Even spacing is important, the more even, the better. The spacing distanse is more about how much amps that can go through the cell. And second; The electricity will always go the eisiest way, so try to isolate the path outside the plates as much as possible. If you use a carbattery-casing f.eks and put 2 plates in each room with one of the plates connect to the nearest plate in the next room, you will get a higly efficient cell.

  • For all who is waiting for my next videos - There will be more videos. I just can not test this cell untill there is winter period in my country (snow in garden) so can't do tests.

  • Looks very interesting, I like your safety valve feature, looking forward to seeing it working.

  • Me too!

  • hienoa! mäki sain ekan tehtyä tosin ihan vaa metallista, ja nyt tein toisenki iha jäätävän ison ei mahdu edes 10L ämpäriin. kennon koko tyyliin 30x15cm :D otan videoita sitku saan jonku alustan sille :D pienestä onki jo video :)

  • That last safety tip is well thought out man, though I'd use stainless steel. I've been watching your progress and something comes to mind. The spacers you are using, between the plates, they are made of foam, yes? That looks to be the case. I think that the material they are made from is a) too airy, and b) too rough. Both of these factors will hinder your hydrogen collection as bubbles will become trapped inside the spacers and on the rough outer edge. Maybe try something smoother and solid?

  • I tried out those plates yesterday. I did add little bit of NaOH in water and it did produce gas well. I think ampers draw was 2-4A because of small amount of electrolyte. I think that is rought foam. It has glue allready in it, so it fit in place realy good! It dont harm by anyway bubbles coming up.

    Thank you for your comment!

  • Just a thought. Your relief tube is not big enough. To have your cell with an explosion proof top is good idea. However HHO when it combust is very strong. Much more then gasoline. Three times more. Point being. Your pop-off relief tube at top is way too small. Try a test with just HHO gas in your container, with your relief tube and give it an ignition to ignite the HHO. You will find the top will blow off into your neighbor's yard 200 yards away. Play it safe. No spark in the chamber at all!

  • Your plate spacing should be as even as possible for maximum efficiency.

    With 7 plates, you have 6 gaps. So your voltage drop will be across the 6 gaps. 13.5v/6gaps=2.25v per gap. This should be fairly efficient.

    You may wish to experiment with 4/5/6 neutral plates to see what works best for you in your application.

    I have some reservations about your use of copper pipe but will be interested to see how it works out for you. I might have chosen nylon or pvc fittings for this ...

  • Cooper pipe is just safety tip. If in cell happend spark and hydrogen will blow up. It will blow up valve in that cooper tube.

    The spacing are big yes. But that are most efficient way. If I use 10A it can be 2-3mm space. If I use 10-40A then 5-8mm. My space are about 5-6,5mm. I will use NaOH for good electrolyte, to get as much as possible good production and efficency.

    The cell himself are ready for first test, I just need to glue on top + and - terminals, and will maybe even test it...

  • ...tonight. I could maybe put Super Glue that can bond those terminals in couple of seconds. And after couple of tests put there epoxy. I use epoxy mostly at all my gluing parts. Its need much time for bonding thigs, but it is strong too!

    I will send you P.M where is PDF file that give much info and data about how to make your cell as much as possible efficency. Even 80-90%

  • before you settle with your final wiring-it would be worth trying positive to the bottle,then the 2 outside plates of the cell negative,and the centre plate positve.

  • Idea is good, but I dont want to broke that SS tube. It would be turn black etc. Also I have used Blank Lack, maked 8 layers, so it now do not make any contact whit water.

  • Nice one,copper in solution?degrades,not so good,Cheers, keep at it!

  • Very good video, 5 stars!

    I am excited to see production and efficiency of your new cell. It seems the space and nuetrals should be ^high efficient. Is it true that the plates divide voltage, even though they share electrolyte? I think they will do so. And your safety blow cap is very good idea. Hope it will work out, looking forword to lawnmower engine.

    Ben.

  • Yes. Hopely it will work if there will be any spark. I say that I will not even try it, just hope that there would be not spark and that preasure will not broke up that cell. Also I need to do FlashBack Arrestors and bubbler.

    I think I could maybe even this week test that cell output.

    I will send you "How to make as possible efficency cell".
