Linnard?s hydrogen on demand system without electricity !

Nice build, ResinRat2!

Give that sealer time to cure then pressurize it with a column of water and submerge that rascal, check fer bubbles.

Hope it does what you plan it to.

Hi Turtle,

I think I will submerge it to test for leaks. As you can see, I won't need your sealed box idea to capture the gas, I have the gas ports for that; but thanks for the idea anyway. If all goes well (no leaks) I'll be in business real quick.

Thanks for your interest.

Hi All,

The design of my reactor will give me a unique opportunity to test a hypothesis I have formed over all this time I have been experimenting with this system. If what I propose is correct, then the use of the fuel cell may give me the ability to thermally speed the regeneration of the zinc electrode enough that no seperate electrical regeneration would be required. This would mean that all the electricity produced by the fuel cell can be used for work, and not for regeneration of the zinc.

Hypothesis: It is known that the fuel cell generates heat as it produces electricity from the hydrogen/air sources. It is therefore proposed that the capturing of this heat to warm only the side of the reactor that holds the zinc electrodes would speed the reactions that regenerate the zinc metal enough to overcome the slower rate of these reactions; allowing the zinc regeneration to occur at a rate that would compete/balance with the hydrogen production rate; thus eliminating the need to electrically regenerate the zinc electrode.

By doing it this way, the zinc side(oxygen production) of the reactor will always be warmer than the tungsten/carbide side(hydrogen production). This would mean that the rate of the zinc regeneration will be speeded, perhaps enough to eliminate the need for electrical zinc regeneration.

The reactions involved from around paragraph [0113] of the patent:

This reaction uses the magnesium colloid to regenerate the zinc as follows:
    2Mg_c + 2Zn⁺² --> 2Mg_c⁺² + 2Zn

This reaction uses the OH^- ions to regenerate the zinc and produce oxygen:
    2Zn⁺² + 4OH^- --> 2H₂O + 2Zn + O₂

By using heat to speed these reactions it may balance the rates enough to eliminate the need for electrical regeneration. By attaching the fuel cell to the zinc side of the reactor the heat will always transfer to the Tungsten/Carbide side of the reactor slower, so that side will always be cooler and the reactions there would always be slower relative to the zinc side.

This will be the first experiment I perform, which will merely be placing the fuel cells under or against the zinc side of the reactor.

My attempts at chemically balancing the reactions failed in the past because I believe as I changed concentrations of one component, it always altered the concentrations of all the other components in the cell, thus slowing one side of the reaction as it sped up the other side of the reaction. Therefore, no improvement in zinc regeneration.

This new method would use heat to simply speed up one side of the reaction, thus favoring the regeneration of the zinc.

Thank you for your interest.

Hi All,

One other thing I need to mention. In the past when I tried to increase the amount of NaOH in the solution, it always ended up kicking out one or both of the colloidal metals that had been previously dissolved in solution. By altering the addition of the colloidal metals until after the NaOH was dissolved in the deionized water, I was able to increase the amount of NaOH to twice the amount from 10grams/100ml of solution to 20g/100ml of solution. When the colloidal metals were added afterward, they did not kick out. So the order of addition was important. First the NaOH, then the colloidal magnesium and colloidal silver.

In the equation from the patent:
    This reaction uses the OH^- ions to regenerate the zinc and produce oxygen:
    2Zn⁺² + 4OH^- --> 2H2O + 2Zn + O2

By being able to increase the amount of OH^- ions, this also helps to speed the regeneration of the zinc without the use of electricity.

Perhaps I can get it even higher in concentration. This would help, as long as the solution doesn't get so viscous that the bubbles can't get through it. LOL!

Just wanted everyone to know what I have been working on as well.

Thanks you for your interest.

Thanks for the details, RR2... it helps us all understand the science behind what's really goin' on in thar-

As the NaOH concentration increases, so does the speed at which the sealers will break down.  Shouldn't affect the case joints, but there will be a point when the adhesives begin to destabilize and liquify...

Oh, "what a fool am I, quoth he..."

I fergot yer a polymer chemist...
DUH!

Back to the pond,
