Linnard?s hydrogen on demand system without electricity !

[Tinker]

Hans what RR is doing is well worth my time and effort to support his work where I can, I think he has a good idea and has shown the fortitude to do the work required to find out.

The downside is that my words or information could cause more problems than they solve. But I will provide information to be accepted or rejected without penalty or recriminations, I wish him well for all of us.   

Thanks for the words.

Hi Tinker,

Thanks very much for the information. The sciencedaily article, of course, didn't reveal anything since they are keeping it secret, but the other article was very interesting. I am sitting here thinking to myself that we have all these big budget companies and organizations trying to find a cheaper fuel cell alternative, and here I am thinking about using graphite pencil refills in an electrolyte solution that contains silver colloids. It is probably good for a laugh.

I think I will hold off doing any research on the fuel cell aspect right now, and just use existing technology. I don't want to get off on a tangent that is so far off what I really want to try and develop that I waste a great deal of time and effort on something that they have been working on for over three decades. My time is worth money too. enough that I would rather put the effort in designing the hydrogen reactor rather than a fuel cell project. Even though platinum is expensive, it seems to be the most explored, reliable, and stable technology that exists today. So there is where I will put my effort as far as the fuel cell aspect of the project goes, and I will concentrate on the hydrogen reactor development.

Also, I have a small potentiometer that I purchased a while back for this project. I haven't used it because I am trying to zap the zinc regeneration  with everything I can sacrifice right now and still keep the fan running. So I haven't had to try to limit it, BUT--- along those lines consider this:

When the regeneration voltage was running around 0.2-0.4 volts the first time, I developed zincates in the zinc side of the reactor that eventually killed the reaction, but the tungsten/carbide side of the reactor was clean. This time I had the regeneration voltage over 0.8 volts running constant and the zinc side of the reactor stayed clean, but now I am getting precipitate on the tungsten/carbide side. So maybe the ideal voltage is somewhere between the two? I don't know for sure. This needs to be explored and experimented with.

As an update the reactor has been running over 165 hours now; remains steady on output of 0.700volts for the fan and 0.835volts for regeneration. I've added water to it once and will add more probably tomorrow or the day after. So it is running steady and true. The solution just doesn't look as pretty on the tungsten/carbide side anymore.

Thanks for all your ideas, and thanks for your interest everyone.

Hey RR,

Can I just ask, are you using purely distilled water for your reactor?
Seems a silly question, but just wondered if the tungsten electrode was perhaps attracting impurities from the water...
Or even impurities dissolved in your 'distilled?' water from the components (i.e. less than 99% clean?)

Just thoughts

A small edit:

Idea: some of the energy could be used to power a small water pump very slowly. Solution pumped out of reaction chamber and 'filtered' back in with gravity assistance?

Again, just thoughts.....I don't have any formal qualifications in any of these fields. just an over active imagination

Hi NssB,

The water I am using is deionized water from my reverse osmosis system at home.  I honestly don't know what the yellowish precipitate is, but it doesn't seem to be hurting the reactor output so far. The reactor has been continuously going for 180 hours now and has the following numbers:        
                Fan: Voltage: 0.712 @ 50mA
   Regeneration: Voltage: 0.858 @ 4.5mA

This gives me 35.6mW(Fan)-3.8mW(regeneration)=31.8mW overunity.

thats: 31.8
         -------   X100= 89% overunity.
         35.6

This means that only about 11% of the total output is being used to regenerate the zinc.

Considering that fuel cells are only about 50% efficient, this is good for comparison of the potential.

These numbers are very small and almost laughable; but they have been very consistant throughout the running time. I can boost the output of this system by enlarging the reactor and installing more tungsten/carbide electrodes. For a first prototype, I think it is doing its job well.

As far as your pump idea, I am hoping that once I gain experience maintaining this system that there should be no need to filter anything out. It should stay clear as long as possible.

Thanks everyone for your patience while I have been learning how to build and operate this system. I must say it has been quite an interesting educational experience so far.
