@@boracay12 Hi, perhaps you could review the diesel mechanics in Perth WA Australia who retro fit there kits to mining company rigs. They boast 25% improvement. I have no experience with it. A larger mining company over there Fortescue Mining has gone away from oil reliance too. Interested to see how these billion dollar companies are doing it. I don't think they are in the time wasting business.

Double thumbs up. Neoprene gaskets can be substituted with cheap easy to cut pvc shower pan liner that one can buy from a local large hardware store. And pvc holds up exelent to sodium and potasium hydroxides. but pvc does not hold up well to a lot of heat so one needs to use very efficient low 2v or less per cell. Also, one may try various heat dissipation methods. Three more thing to consider. 1) Excessive amps per sq area will make lots of gas bubbles that may aggressively lead to early graphite plate deterioration. One may aim for more plate area with a lower amp per sq area. I dont have an amp per sq area to recomend shooting for. That may require experimentation. 2) gas build up at the top will reduce the plate surface area submerged in electrolyte. If each sq area were thought of as a resistor allowing a certain amount of current, then doubling the area halfs the effective resistance like two resistors in parallel. 3) gas bubbles on the plates and in solution between the plates reduce the effective area through which current can be conducted through the electrolyte. Way to mitigate issues two and three is to circulating electrolyte with a pump pushing gases and electrolyte out of the cells. Maybe orentate the cell to have one corner facing up and the gas discharge hole at the top and an electrolyte refill hole at the bottom corner. Other ideas to I've seen people do and may spark interest. 1) Magnets. I suspect magnetic fields transverse to the flow of current can induce the electrolyte to move move at 90 degrees to both the magnetic field and the direction of current (along the the surface of a plate), and that this electrolyte magnetohydrodynamic flow can help break bubbles free from the surface of the electrodes helping maximize the active electrode surface area. 2) People have used ultrasonic transducers to break bubbles from the surface more quickly. Although, I suspect it may speek breaking down the electrodes. 3) I've seen people use a vacuum pressure to expand the gasses presumably this helps bring the gasses out of solution faster but I'm not sure how much it helps maximizing active plate surface area with expanded bubbles between the plates, and expanded gas does not mean more gas production.

Robert... good to see some of this technology coming back around. Let's hope it's not suppressed by the oil companies again like before. I had a 12 cell pro-built 'dry cell' setup in a rebuilt 1971 VW Beetle. Also had a PWM controlled DC to DC power supply to regulate voltage and current from the battery. Using sodium hydroxide for a catalyst with water, I was producing around 3.5 - 4 LPM of HHO @12 vdc and 18 amps. I had done many road tests with this setup and gained about 8 mpg. consistently at cruising speeds. (The best it would get without HHO was around 30 mpg, but *with* HHO it would do 38 mpg or even more in some cases). Of course you can't produce enough HHO to actually *run* the engine on HHO, but the catalytic effect with regular gas in the combustion chamber made it much more efficient. Unless you can decipher Bob Myers secrets from years ago (RIP), you'll probably never be able to reach those levels. That said, I like your experiments with the graphite 'foil'. The only thing I see that would be a problem over time is the graphite flaking off and deteriorating over time. This might be offset by having it contained in some sort of plastic mesh maybe? Now subbed and will be watching for future developments.😉

It used a MIG wire feed system to supply the wire as it was the anode and the cylinder was the cathode. a voltage was put across the two materials and the wire eroded releasing Hydrogen.

That's astounding! Thanks for the demonstration of the technique. Well worth experimenting with different surface areas, to see if there's an optimum for that foil.

What nice? It is not hydrogen generator as is written in title, it is brown's gas generator. Brown's gas is dangerous, it explodes very loudly from very small spark. Hydrogen instead burns mildly.

Thank you for your content, Robert. Im almost done building a dry cell with gas separation, hoping to work with urea. The problem I see with doing this efficiently long term is the cost of KOH which is carbonated in this reaction. If you think urea electrolysis is worth while, could you do a video or few covering regenerating the KOH? The two main ways I see are calcining at 1300c or reacting the K2CO3 with HCl yielding KCl, then electrolyzing to get KOH H2 and Cl2 which can be flowed past a UV light and distilled back to HCl. We could use an efficiency comparison. Without regenerating the KOH, the hydrogen produced, through a fuel cell, costs about $17 per kWh. Completely unsustainable.

Well, hell then! Forget the stainless all together. I wonder if there’s a neutral electrolyte, like washing soda that could be nearly as efficient in conjunction with the graphite foil.

The cells are like a battery, you can over and under charge the cells. 2.2 volts is typical running voltage. Any heat produced is of coarse inefficient. I have built very sophisticated extreme efficient cells that generate zero heat. The trick is too isolate all exposed edges and the electrolyte between cells can not be shared. I built a tubular system that had plastic manifolds gas and electrolyte porting. the edges of the tube ends isolated in these manifolds with O rings separating them from the electrolyte. Each cell had its own resivour for its electrolyte. The cells were then wired in series to achieve 2.2 volts from 14.5 volt supply.

Brilliant video, you remind me of my old tutor when I was an apprentice instrumentation engineer. FYI you can use magnets to isolate oxygen from hydrogen (I've seen this done in the bubbler, with a wall divider and diffuser with strong N/S pole magnets on each side). Also look at PWM circuits and frequencies in the 2.4KHZ range are reported to excite water molecules and help to break the covalent bonds to produce more gas. Try a 3 phase square wave form invertor, high frequency and experiment from there. I've read it is possible to run 3 separate PWM circuits (standard high wattage LED dimmers for example, cheap and easy to obtain and modify) then use a common neutral and have all three circuits tuned and balanced to the same frequency (oscilloscope and potentiometer to adjust) and each applied to their own electrodes. Electrodes need to be tuned too, if they are precisely manufactured and balanced with one another (mass + ohms resistance) it helps the circuit to reach resonance and maximum HHO production.

Have you tried separating the gas streams? Means you have to introduce a gas tight middle layer (if the carbon sheets are not gas tight enough) and gas separator membrane/micro-mesh in between. Could anyone tell me cheap gas sensors to get a direct reading of O2 and H2 concentration? Have to dig into spectroscopy :)

This is very cool! thanks for another awesome video, will be interesting to watch the follow up videos, by the way that design is very clever is that similar to what they use in other cells/papers ? with the layers, rubber etc, thats impressive how it works ..

This is an amazing build. I just wonder how one would go about storing hydrogen for later use, like a stove for example.

I would really love to see a video on converting hydrogen and oxygen back into electricity.

@@ThinkingandTinkering Yes, there are next to no videos on home made ones. I was thinking of using a a capacitor of some sort like a Kelvins water dropper to separate the charges instead of materials like platinum. I never got to playing around and thinking further on it. Anyways I would love to see your take on a fuel cell.

Robert Murray-Smith Hello Sir, have you ever heard of a coil that, instead of having copper, has liquid mercury in a thin hose? And it would work just like a coil, but with liquid mercury.

Thank you Robert. It is very good to see some one I've grown to trust, doing HHO vids. I'm off grid, and in the winter months I supplement my solar with a 12K watt gen running on Gasoline. Would be great if I could produce my own fuel to run the gen set. HHO seems promising. Again, thank you.

Thank you for all your research and sharing

How thick was your graphene sheet? I bought my through Amazon and it was too thin, .005” What is the ideal thickness for this project? Thank you very much

how a magnetic field will increase production on your cell ? ( another video from you showed increased production in a magnetic field) keep your good work.

I'll say it again Rob - try Extruded Carbon Water Filters, submerged in electrolyte... it's all about surface area (4000m^2 in a standard 250mm Cartridge) and the correct pulse frequency (25A 82V @ 300kHz) to obtain optimum resonance. Adding a small brushless circulation pump helps improve gas removal from Filters to improve efficiency.

@@delawarecop no, I would start at 0 Hz and go up logarithmic to the limit of the electronic circuit. Maybe around 500kHz or 1Mhz. That depends on the electronic that need to be suited for that. After doing the impedance measurement, I would do an output measurement at 0 Hz, resonance frequency and +/- 30% around it.

Wonderful build. I too am wondering about how much improvement you would be able to make to this if you used en urea solution for the electrolyte and a magnet for agitation. I was also wondering if pumping the electolyte through the dry cell would increase efficiency. Wonderful video despite making me wonder. Have a nice day.

cheers mate and exactly my thoughts - so I will be trying these ideas for sure

@Robert Murry-Smith what I've discovered a couple of years ago, when I had 2 neutral cells between each positive and negative electrode is that depending on the electrolyte, it behaved as a battery. It kept some of the voltage and amperage we used for electrolysis. We used stainless steel electrodes. Would it behave the same way with graphite?

yes mate - there is some H+ and OH- entrained but self discharge and efficiency are always going to be rubbish with this kind of arrangement for batteries

During my test, when doing slow (long duration) pulse width modulation, I also noticed huge but brief in rush current very much the same as if one were working with a capacitor. I suspect that was due to capactance effects at voltages less than 1.24 volts per cell where the electrolyte acts as a dielectric between the plates of a capacitor, storing energy in the dielectric that can be latter released as you observed.

@@kreynolds1123 I've done the same experience and I found out that 1.5 volts per cell would be most efficient, as it would prevent evaporation losses. I've tested a variety of displacements and found out that the production level would be proportional to the distance between negative and positive cell. I've tested without neutral cell and with one neutral cell between electrodes. And tried to increase electrolyte concentration as well. I had a Volvo which I was planning to run on hydrogen from water. I found out that the best would be combining with redox reaction as it is easy to split water vapour by oxidation. As the result of the combustion was water vapour, I was designing a catalytic converter to replace the existing one for this intention. Well, as soon as I had to go to Belfast, my wife sold the car. Ridiculously price that would not even pay for the tires.

Depending on the model of the original hho machine, I believe you will find that it will produce around 1L/min of hho gas. If one uses that as your benchmark, it would be very interesting to see what the output of your graphite dry cell is. Further to this, given that a urea solution is able to produce hydrogen at 1/4 the voltage (0.37v instead of 1.27v) this would be an additional step, but an interesting one to explore! Looking forward to seeing what you can do with this!

Hello Robert, if you think stainless is a bitch to work with try titanium. But supposedly titanium plated with platinum is the best plate material period according to laboratory papers. Since you used graphite plate material instead, what is the materials total name ??? Just graphite or reinforced graphite sheet ??? How about the electrolyte used Sir. What did you use ???? One more thing Rob, what was the efficiency compared to using standard material which is stainless ??? Thanks a bunch Sir and peace to you too. V

As usual Robert. A very interesting and informative video. I just wondered what you thought about concrete batteries.

What a Coincidence! I have about 50 feet of 4 foot wide roll of this Pure Graphite sheet. Very Fragile, looked it up once, it's used for High Heat Gaskets & I heated it Red Hot & no flaking or damage. I'm In!

Really great Video, tank pure for sharing alle these information. What thickness of the graphite foil did you use? I'm sorry if it's mentioned in the video, missed it. Does the thickness matter, or shouldn't be there a big difference in efficiency?

thickness doesn't really matter that much - it will be more conductive as a bulk property but it is really a waste of material if it is too thick and it costs more

Great work!

Toyota is using graphite and platinum. Would love to see that combo for the plates.

Hi Robert , thanks for explaining making the dry cell . I've used stainless wire for my effort, wound spirally round a 2 inch core , which got thinner and thinner ! I would like to make a dry cell like yours , but where did you get the graphite sheet ?

I appreciate your work. It is inspiring. Since you made a hydrogen generate from graphite, do you think you can make a fuel cell hydrogen from graphite too.

Very fascinating, I hope to see a piece of a catalytic convertor brick being put in the flame.

Fascinating! How much heat is it producing? The standard DIY HHOs(leads especially)get very hot.

Great! Have you tought or tried to keep the O2 and H2 separated/collected to different reservoir in the solution? Like collecting the O2 up above the anode and H2 up above the cathode (or vice versa :)? To combine both gases only when reaching the torch nozzle, similarly as when welding with acethylene and oxygen? My application would concern the welding only.

Love it Robert are they still sacrificial the graphite plates?

Instead of cutting gaskets, you could use neoprene gasket cement, ''neoprene in a tube''. You would need some material as spacers but that could just be strips of plastic, single or double sided sticky tape maybe, very easy to cut.
