Linnard?s hydrogen on demand system without electricity !

Hi Chris and Mark,

Just FYI along these lines.

The test cell I had built to mimick your setup never achieved a state of being endothermic. Every measurement I made with a digital thermometer indicated that the test cell was always running approximately ONE degree (F) above room temperature. These were side by side direct measurements in my temperature and humidity controlled basement.

This disappointed me a bit because I expected that once the zinc was being regenerated that the temperature of the electrolyte solution would drop below room temperature. This never happened.

So my previous hypothesis that the system runs endothermic was incorrect. At least with this three electrode set up.

The old four-electrode setup may act differently. It may be endothermic, but I never took the opportunity to carefully measure that property. This is something I planned on doing with the 2 liter reactor.

Thanks for your interest,

Hi Dave,

My setup is also in a basment and the temperature is always 26 Degrees C. I was unable to replicate your exothermic test? My test read identical using a digital thermometer over a few days of usage?

I'm building yet another cell bringing me to two three electrode cells and one four electrode cell to test a few other ideas while leaving the other two running.

The Tablespoon cell is still ticking with no visible changes.

Hi Chris,

I was going to put a resistor between the zinc and the tungsten-carbide hydrogen producing electrode like you did, but I was thinking of using a smaller resistor so the hydrogen gas can be produced as fast as possible without the zinc being allowed to plate. You said you are using a 2.5Ohm resistor; do you think a smaller one would work better? What about a variable resistor there instead so it could be fine-tuned?

I really like your idea. Can you recommend some part that would fit the bill?

Thanks,

Hi Dave,

I saw a buildup of particles in the bottom of the tablespoon reactor and in placing the third cell into the setup caused the voltage to drop in the tablespoon reactor. This caused the entire plated surface to sheer off and short all three cells.

I shook the crap out of the cell causing all the shearing to break up in the bottom of the cell and put it back into production without opening the cell or making any changes with the hopes of recovering it. I have the third cell designed to test an idea to prevent any buildup at the base of the cell.

As for the resistance... both the tungsten and zinc electrodes have and end to end resistance of 0.003 Ohms in my setup. By adding a 2.5 Ohm resistance I am making the plating on the zinc 834.3% more preferable to plating on the tungsten while still allowing the generation to continue. I wanted to test this with this higher resistance as I mentioned earlier in this thread that shorting out a chemical car battery causes degradation leading to total breakdown in the cell. This may be similar in electrochemistry to a lead acid cell and I wanted to try to introduce a load to prevent zincate buildups while allowing us to increase the voltage over the 0.9V limit.

A smaller resistance would be preferable and I want to get to that stage once I have tested this way... less chance of damaging the cell at least...

I do have a small variable resistor that I found in my spare parts. I don't know what size it is but I could give it a try and see if I can play with the hydrogen output. This would probably work OK for what I am trying to test for.
