Linnard?s hydrogen on demand system without electricity !

RR,

that reactor is SWEET!!!!

cant wait to see what it can do.

i am very curious to see what the reactor does at differing ambient temperatures.
outside on a hot day, in the refrigerator, etc...

best of luck to you,

Hi Chris,

I decided to go back to my original electrode arrangement. The use of the configuration similar to your experiment caused zinc hydroxide to plate like crazy on my tungsten-carbide electrodes. I guess 0.77 volts is too high. I don't have a way to control the output of the fuel cell, short of adding extra fans in the circuit to suck out juice, so I am going back to using two zinc electrodes, one for hydrogen production and one for regeneration, and switching them every 6 or 8 hours or so.

So the same thing happened to me, and the fuel cells did not prevent the zinc plating on the tungsten-carbide rods.

I guess you need to go back to your lower voltages and try your experiment that way.

I can, however, add my third and larger fuel cell to this arrangement and perhaps get a voltage going so a circuit can be designed to do the switching of the zinc electrodes automatically.

I will start experiments in that direction.

Hi Dave,

I've had no luck with my configuration. Something is still unbalanced at 0.84V. I'll try it again and the carbon idea but right now I just need to make one that works. I have switched to the two and two configuration and am working on a timer circuit and relay to switch the electrodes every 30 minutes.

Will let you know how it goes

Thanks,

Chris

I've had no luck with my configuration. Something is still unbalanced at 0.84V.

Maybe the voltage, in this configuration, is too high. I still like your idea of the one zinc electrode. Maybe the voltage just needs to be lower to work? I really hate to abandon your idea until it was checked out better. I can't help thinking that there is a correct voltage that would give just the right balance to the reaction and encourage the zinc to replate without "pushing" the plating too far and cause zinc to plate on the tungsten electrode.

I think I will try your configuration, but put some type of variable resistor in the circuit to fine tune the output voltage so I can slowly step it up a little at a time. I just need to see what type of variable resistor would work so that this can be investigated. Any ideas? Something I could buy at Radio Shack?

Thanks for your efforts Chris.

Hi Dave,

Definatly not abandoning the idea... I need to collect more data in the form of current used in the cell relative to zinc surface area. With this data from a working cell I can apply it to the 3 electrode setup.

I am using a three connector 200KOhm pot for my voltage adjustment. I need a smaller pot as well for the fine tuning. http://en.wikipedia.org/wiki/Potentiometer

Look at the schematics there under "Theory of operation". Use a 200KOhm pot and a voltage supply of 5V (from a phone charger, the lower the voltage the better), this will allow you to tune to any voltage between 0 and 5V. This way is impossible to accuratly get to a specific voltage easily, I'm working on an easier circuit and will post one when i'm done.

Thanks,

Chris
