Linnard?s hydrogen on demand system without electricity !

Actually I just had a simpler thought. I'll use my tap and die set. Tap a thread in the hole and one on the electrode and Viola': just screw the aluminum electrode into the zinc. Simple.

I like simple.

Thanks for your interest.

ResinRat2,

Sometimes simple things are the hardest to find, we always look at the hard way. your way is very good idea. Simple and gives you a chance to change it if you need to.

have a good night !

Just a thought,  when I deal with issues like this I also try and take into consideration what metallurgical properties I am up against. Paul, not a bad idea to heat one up and then you can even cool the other part down, stick it in the freezer for awhile or use a fire extinguisher on it to cool it down. I  just wonder this. When you use two dissimilar metals, which one will expand first when it gets hot?

They all vary like crazy. Here is a table from the NPL:

Hi Everyone,

I've got some interesting results

I took a zinc electrode and drilled a hole through its top, then threaded it. Next I took a thinner aluminum electrode and tapped a thread around its end. This I inserted into the zinc electrode. Next I took a fresh solution of the NaOH, Mg, Ag, and deionized water and inserted this electrode so only the zinc was immersed. I added a tungsten electrode to the cell. This is a normal control cell except that the zinc electrode has an aluminum electrode inserted in its top. Pictures are posted below.

Normally when I connect the zinc and tungsten electrodes in a normal control cell the tungsten begins to give off hydrogen gas.

In this cell there was no activity off the tungsten or zinc. No gas at all. This is odd in itself; but what is most interesting is that if I take the connection off the zinc surface and connect the tungsten electrode and aluminum portion of the zinc/aluminum electrode, then the tungsten immediately begins giving off gas at the normal rate.

What does this mean? I don't know right now. This is new ground and I am anxious to see what happens. I know that if I put an aluminum electrode in solution that has had the reaction going for a while, that zinc hydroxide will begin to replate on the aluminum electrode, and keep going until there is a huge blob.

In this case I am not sure but my hypothesis is that the zinc will replate as it is consumed by the reaction. I am probably wrong but I don't know for sure. We will see as the time progresses.

Thank you for your interest.

ResinRat2,

Now, this is getting very interesting, looks like you may be on to something. You are really sticking with this and it will pay off, I am sure. I wish I could shed more light on the subject, but I don't have the chemistry background that you do. If you get in a situation you need something just let me know and If I can help, I will.

Regards
