Linnard?s hydrogen on demand system without electricity !

Hi Dingus,

I am thinking of an angle here that I plan on experimenting with. Plating the aluminum with zinc may be difficult to do properly. I am thinking that as long as the aluminum is protected from the NaOH solution, that it won't be consumed so this is what I propose:

Take a zinc electrode, drill a small hole into it, and "force" an aluminum wire or electrode into the hole. Then lower the zinc/aluminum electrode into the reactor solution. This would be a protective coating of the entire zinc electrode over the aluminum. Then see what happens.

I have a feeling the zinc will replate on the zinc electrode without electrical power. Next, connect this to a tungsten electrode, but connect it on a zinc surface, not the aluminum one. This seems strange, but I am hoping by avoiding electrical contact with the aluminum electrode then the aluminum can encourage the replating of the zinc at the same time the zinc is being consumed without consuming the aluminum. I think you know what I mean.

I will try this out as soon as I get more aluminum electrodes. Probably tommorrow.

You could drill the zinc rod with the small hole the size of your aluminium wire. Then heat the zinc rod, which will expand, and then feed in the aluminium wire. When the
zinc rod cools, it will be a good tight fit with a Al wire.

Hi Paul,

I'll consider this. Maybe a 250?F oven. Drill the hole in the zinc electrode just smaller than the aluminum electrode. Pop the zinc in the oven for a bit, then insert the aluminum electrode into the hot zinc and let it cool. Sounds good. I'll probably do it this way. Thanks.

That may make be a very tight fit. In theory, the same size will be pretty secure.
At room temperature, you cannot get a 0.5inch shaft into a 0.5inch hole. It will
not go, whatever you do (except heating up the hole, and sweating it in, of course).

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? If the part that you are making the hole in expands faster than the one part you are putting in the hole then you may have an issue.  If it is the other way then fine you are in good shape. What temperature will this system run at when it is all said and done?

For a test mode I am sure you would have no issues like Paul said, I am just trying to think ahead is all. The more things that are brought up now, the less things that will need to be covered later.
