Hi Dave,

My power supply is only good for about 150mW not far from H2+Air fuel cell.

The voltage is now at 0.620V and rising slowly. Production is still really good and the cell remains so cloudy that you can barely make out the rods in the middle in the top 3/4 of the cell.

I am keeping a running log on this cell and as I'm using lab gear I have no gas leaks or fluid spills ;) yet...

Hi Dave,

Have you tried increasing your zinc surface area to produce more gas?

I noticed in all your setups that you are focusing on the tungsten alone, ever try one with more zinc surface area? I only say this because when I turn my cell on... and I have a much higher zinc surface area than tungsten... my tiny tungsten rod erupts with gas and the entire cell is totally cloudy. Then the zinc spiral gets a layer of O2 bubbles and the production of H2 decreases to the point where I can now see the rods. I am thinking that the O2 bubbles are reducing the zinc surface area and slowing down the reaction?

Just my 2 cents.

Hi Chris,

You might be right about increasing the zinc surface area. That is possible, or perhaps  you maxed out your hydrogen production. Increase the number of tungsten/carbide rods and see how the hydrogen output increases. If it doesn't then maybe what you are saying is right. Look carefully at the tungsten electrode and look for zinc plating. If there is none then throw in a few dozen tungsten electrodes and see if the output goes higher. Leave only one tungsten for the regeneration, but jack up the number of tungsten for hydrogen production. See how that increases the hydrogen output.

I don't have a reactor right now, it is being worked on for me, but as soon as I get one I will do this with the fuel cell. What is nice is that the fuel cell has a load following capability. I was afraid to do your type of setup because of the battery heating that I saw during the previous experiment similar to the one you are doing. I didn't want to damage my fuel cell. Now I know this is possible and can have a good possibility of success.

This is cool. I am really excited by your results Chris. This may turn out to be the final piece of the puzzle to make this system work continuously without switching zinc rods for regeneration. I am very, very glad you tried this angle. That is why I wanted help with this project. Someone to bounce ideas off of and share results with. See what has happened in just a short time.

Hi Chris,

I took a snapshot of the page in my notebook when I did the similar setup. Good for a laugh, you can see my comments, "This is how to balance the reaction electrically w/ the fuel cell" and  "Causes battery to heat up" and "No good!"

I guess I was wrong LOL!!

Thanks again for doing what you are doing.

Aaaah... Now I see why your battery was heating up... That setup is very similar to mine but you have both tungsten rods wired for production and then added a battery to the apparatus.

If you look closely you have short circuited the battery by directly attaching it in that way... current flows from the battery, up the zinc rod and then directly back into the battery again. All without passing through the electrolyte. We used to do this as kids in school with a quarter and a nine volt battery, we would put the quarter on the battery (shorting the terminals) and secure it with a rubber band and then throw it to a good friend to catch it... much worse than hot potato!!! Both the battery and the quarter were blistering hot!

If you disconnect the wire between the zinc rod and the regeneration tungsten electrode... you have what I have.

Glad to see you going back into your notes :) I think we inspire each other! 2007!!! Didn't realize you have been at it for this long! The end is near my friend  ;)

That voltage you gave me is still working well... No precipitate of any kind and the zinc is once again furry  :D No buildup on the regen electrode either... will keep a close eye on this.

Cheers,

Chris

Good job at seeing my simple mistake. Very, very nice.

See, it is simple things like this that I easily miss that cause many failures. That is also why I keep the notebook and try to put as many details as I can into it. It is my permanent record of things I have tried in the past. See, once again it has paid off for me.

Adjusting your voltage may be a bit of trial and error. I hope the number I gave you will be the same for your setup as it was for my old one. That was the one that ran almost twenty days. If the voltage is too low then your zinc will form as a zincate on the zinc rod, kind of a blobbish grey "soft" type of coating. That is the best way I can describe it. It will kill your reaction. If the voltage is too high then the tungsten from your tungsten regeneration electrode will plate on the zinc electrode, or the zinc will plate on your tungsten hydrogen producing electrode. Watch for both carefully.

This is very exciting for me to see. You may laugh, but that is the way I am. Simple things please simple minds I guess, LOL!

Hi Dave,

One more question, I am supplying the cell with the 0.840V in the middle of the range but the voltage I am seeing at the cell is much higher.

If I put my meter probes across the cell with the power supply attached it reads over 1V but if I disconnect the power supply and test that, It reads 0.840V...

Which voltage am I to keep in that range? the supply voltage or the overall cell voltage?

Thanks,

Chris

I measured my voltage by placing the probes across the electrodes when the power supply (fuel cell) was attached. That reading should be the target of 0.83-0.85 volts to match what I was doing with my small reactor experiment. So I guess in your case that would be the overall voltage as you defined it.

Hope that helps.

Thanks again,

Dave (RR2)

Hi Dave,

Balancing that voltage with the power supply I am using is proving to be a royal pain. My fuel cells haven't arrived as yet so i'll need to get a decent temporary power supply together.

The previous cell ate itself as the tungsten electrode had a plating over it and the zinc was almost to nothing. Voltage was over 0.9V for too long.

Working on it.

Chris,

I guess that is where the fuel cell has a bit of an advantage. It only supplies the voltage that is needed and doesn't "press" it forward. It would have helped in this case. I apologize if my advice was misunderstood and caused the plating.

You can buff the zinc off the tungsten by using a metal buffing wheel or a grinding wheel. The tungsten won't be damaged by it at all.

I have seen what you described, and it happened to me a few times before I finally understood what to look for and how to avoid it. There is a bit of a balance here. Too little, or not enough voltage hurts you either way. That is why I found the fuel cell's load following capability very useful for this application. 0.83-0.85 volts should do it.

Hi All,

I have finally been motivated to test the hypothesis that the Linnard Griffin electrolysis process runs endothermic and absorbs energy from the atmosphere that surrounds it. I am sorry to say that I have results that give an opposite conclusion.

I placed within a glass jar reactor approximately 100ml of electrolyte solution. Into this was placed three zinc electrodes and one tungsten carbide electrode. The tungsten carbide electrode and the zinc electrodes were not allowed to touch and the reactor was allowed to stand overnight to equilibrate its temperature.

Starting temperature ----- 72.3?F

I then connected the tungsten carbide electrode to the three zinc electrodes with a copper wire and the system began to give off hydrogen gas.

After a few seconds the temperature rose to 72.5?F and remained there for several minutes.

I then added another tungsten carbide electrode and connected it to the zinc with a copper wire.

After several seconds the temperature rose to 72.6?F where it remained for several minutes.

I then connected a third tungsten carbide electrode to the system. This time the temperature rose to 72.8?F and remained there for several minutes. Finally peaking at 73.0?F.

Room temperature was 72.1?F.This is in my basement, temperature and humidity controlled area.

So this tells me that my hypothesis that the system runs endothermic is incorrect. At least as it is.

Now, perhaps that will change once the fuel cell is added. This will be speeding the regeneration of the zinc in the system. I don't know yet if this would lower the temperature of the electrolyte solution or not, but as it is, the system is not endothermic. It looks slightly exothermic. So it would not  be absorbing energy from the atmosphere as it is.

Once I get my reactor back and add the fuel cell I will do temperature studies on its operation to prove definitively whether it is endothermic or not.This will help give an indication as to whether the system can achieve overunity or not.

Thanks for your interest.

Also, Chris,

I decided to try your electrode arrangement for the first test. To me it looked great and using the fuel cells gives me a voltage of about 0.80 - 0.85V across the fuel cell, and a voltage of 0.775V across the regeneration tungsten and zinc electrodes.

I guess this is the voltage to shoot for right now.

Video posted soon.

Thanks again Chris for trying your configuration idea.  I would have never gone back and tried it if it wasn't for your work.
