Linnard?s hydrogen on demand system without electricity !

[ResinRat2]

Well, what is interesting is that the system has been running a few days now with the zinc/aluminum electrode. Once the connection was made to the aluminum portion (not the zinc portion) of the electrode the gas started coming off the tungsten again. There is now plenty of replated zinc "threads" all up and down the zinc surface.

Subjectively, it seems to me the rate of hydrogen production is not as fast of a rate as when there was no aluminum involved. Maybe the aluminum is balancing the zinc replating and slowing the hydrogen production rate slightly in order to keep the two in balance. I'm not sure though. I would need the reactor finished and gas rates to be studied.

Ahhh, so much to do, so little time to play with this. My wife is not too happy right now but I mentioned to her that I could have other vices (smokin, drinkin, gamblin, bar-hopping, etc....)lol. Women! Good thing I don't care that I'm going bald or I might be spending the time getting hair-plugs or sports-cars! lol!!

Thanks for your interest.

Hi Dingus,

How about this crazy idea. Two zinc electrodes in the reactor side by side (very close but not touching). One has the aluminum rod inserted and is not hooked up to anything. The other (no aluminum) is hooked to the tungsten. The theory is that the hydrogen production will not be slowed and the zinc can replate on the zinc/aluminum electrode.

Once a day the aluminum can be switched to the other zinc electrode (no connection to anything) and the now replated electrode is hooked to the tungsten.

By doing this I hope to avoid the slowing of the hydrogen production while still keeping the zinc replating at the maximum rate.

I think I will try it at home when I get a chance.

Hmmmmm...

The first thing I feel I should say is that the proximity of the two zinc electrodes to one another is much less important then the proximity of tungsten to zinc. Since the zinc rods will never play the role of both anode and cathode at the same time and circuit, they must only be close to there opposites to lower the amperage comsumed during reduction. BTW I have to run some more tests, and I was getting a slow trickle of reduction bubbles at .7 volts... which is less then the self potential of the cell... Anyone know what that means?

The close proximity of the zinc electrodes is only to facilitate quick reduction. Oxidized from the electrode without the aluminum, almost instantly reduced by the electrode with the aluminum. That was my thinking on the zinc, not that one would be anode and the other cathode.

As far as your low voltage regeneration experiments:

Posted by deltat earlier. Notice only 0.9 volts is indicated to regenerate the zinc electrode. This is close to your results. Good Job Chris.

To be honnest...  I'm more interested in your zinc whisker progress. Please send us some pics when the replating whiskers are readily visable on your cam. I wonder if this was Dr. Griffin's intentions...
