Hey RR,

Sorry to have dropped off the planet!

That sounds like an interesting idea you have there that could be switched by a simple relay... I think i'll give it a shot as it would get rid of the resistors that crap out the massive gas generation i'm used to.

Will give it a crack this weekend and let you know.

Cheers,

Chris

Hi Chris,

If you can give it a try I would appreciate that. Let's see if you can duplicate my results.

I think it looks pretty good from my end so I will plan on using this type of setup in the larger reactor. I am building a mechanical timing switch right now that will be running off the fan motor. I think I will set it up to switch every hour from regeneration to non-regeneration mode, then back again. In a continuous loop. That way the switch is running off the fuel cell and the unit is just producing a continuous stream of hydrogen gas.

I appreciate your efforts on this Chris. You helped to give this project a new direction and a new life.

It will feel good to get the larger reactor back in operation.

@ALL,

no need to reply, but someone at some point should try varying the "duty cycle" of the timer. That is the percent of time it is "on"
versus time it is "off". More than likely it is currently 50%<->50%.  The duty cycle percent should match the reaction rates to try to
keep the re-plate reaction centered over the metal ion concentration in the electrolyte. It could very well be that the duty cycle is more
important than the absolute time. If the re-plate state is held onto too long it could cause abnormal or undesirable side reactions to
occur over time.

I agree Mark, but the only way this would be determined is experimentally. Once I get the larger reactor going with the timer I will be doing trial and error tests on the regeneration timing. It will probably take some time before we determine the ideal timing cycle.

I have read over the first 3 pages of this thread and have managed only today to get a full copy of Linnard's patent.I am a chemist(B.S.) and of course am very interested in all that is going on in this thread.Safety is always a top concern  here.I do know of a system to get only H2( through formation of a metal hydroxide).Two metal electrodes of iron(most metals,not copper,will do) are put into a saltwater solution.Then a small electric current is put across the electrodes and H2 gas boils off both electrodes.The oxygen does not come off as a gas but is tied up as a metal
hydroxide(a solid powder which settles to the bottom of the container).So one electrode is eaten up.The other one is not(until the polarity of the current is reversed).The beauty of this system is that most metals can be used and 0.91lbs of metal will generate close to 10 gallons of gasoline energy (in H2).So a  pound of aluminun cans can get you about 10 gallons of
of gasoline (in energy).Also a lb of junk iron.I will have to spend more time here to be able to really help you guys out.Triffid

lye and aluminum will react until the lye or the aluminum is all used up.You don't even need another metal in the reaction to get H2.Triffid

Triffid;

Its always has been possible to convert metal to a metal oxide or metal chloride and hydrogen gas. The pefered way to inflate
those large hydrogen filled experimental balloons is to use HCl acid and put in large chunks of scrap aluminum metal. The
question is what do you do with the aluminum chloride or alumina that results. One nice thing about alumina is that it is
already present in the environment from rocks but that aluminum metal still costs. Of course in the Linnard reaction everything
is recycled automatically, which is the hope ~ Long period of reactions without any additional reactants added except water.

I have read over the Linnard patent and it pretty much blows away everything else I have ever seen on hydrogen generation.Brute force electrolysis is a dead horse and I will treat it as such.The junk iron and saltwater method was a favorite of mine from 15 years ago.But again its a dead horse because  there is waste to contend with from there.Back in the early 90's I was so bored with my job I took to doing chemistry experiments in my kitchen and one of those included doing homemade collidal silver solutions(sorry if I mispelled anything).I was very surprised later to find people paying 50 dollars or more for a little bottle of the stuff.When I knew how to make gallons of the stuff(i just don't know the ppm).So I know how to make collidal suspensions of these metals.Looking over the recipe for experiment 13.It seems to me that twice as many silver ions are used as magnesium ions.So starting with that observation I think I can make the collidal solns and by trial and error find the right amount that works.I do have shavings of magnesium from a machine shop,Also U.S. silver coins supply the silver.Also since 1983 every U.S. penny is copperplated Zinc.It seems I have the starting materials  to make the collidal solutions.For a source of the metal nickel
canadian dimes are nearly pure nickel.The US nickel has about 25% nickel in it.But I would not fool with it.I now Think I can power my car with hydrogen gas.Triffid

My colloidal silver solutions were not what you would consider " food grade"
But they might be ok to generate hydrogen.Triffid

I have finally read all 31 pages of this thread!!!A method of making colloidal solutions was given earlier in this thread.that I agree with :ie you put two pure pieces of the desired metal in distilled water(not tap water,not well water),run an electric current though it for about 15 minutes(I like using dc adapters not more than 12 volts).Another post here talked about testing your colloidal solution with salt.That told me my homemade colloidal silver was at least 10ppm.I got a milky color.Then yesterday I got to spend two hours reading the linnard patent again and experiment # six caught my interest.No metal is used and no acid is used.The reaction starts about at 90 degrees C. After a while the metal is regenerated and the acid has been formed.In this case both the metal and the acid was formed later as the reaction progressed from the intitial reactants.They started with FeCl3 and H2O which turns into reduced iron and HCl.Once the iron is reduced(a bare metal) and the acid has formed then the reaction
settles down into needing 65 degrees C to run and puts out (hopefully)a steady supply of hydrogen.Still a bit hot like underneath the hood of a running car?I guess my point here is that no one here has worked on this.So I will !!!! Using homemade colloidal lead and magnesium solutions made from lead weights used to balance car wheels and magnesium shavings from a machine shop.Someone here expressed caution that colloidal lead solutions may be a little nasty to work with.My hope is that this reaction is the one to power a car with hydrogen to burn.I think too that I should mention that toy chemistry kits are available in the stores for anyone wanting to learn more about chemistry.Some kits have pretty good scales for weighing things.I tend to collect them myself.I was looking at about three of them that I have last night.Thought I should say something about it.I still want the ambient room temp project to succeed.I think thats the prize we all want.Way to go Resin Rat 2!!!!

Just a couple of chemistry tips :1.)  20 drops of water from a normal eyedropper equals one ml.
2.)one cubic centimeter water = one ml=one gram(of water)
3.) water is both a weak base and a weak acid.
I don't know how number three fits into the work here but I have a hunch that it does.Have a good weekend all.Triffid

Hi All,

I finally have the regeneration timer going. This is set up with Tacimatrix setup three-electrodes with regeneration. I have the timer operational. It is made from an old wall clock I modified to switch the regeneration (0.885 volts) on and off every five minutes while the hydrogen is in production all the time.

This simulates one fuel cell being used to run the timer and the other fuel cell being used for regeneration. The timer runs off 1.5 volts and the regeneration is being controlled by a variac so 0.883 volts is being used for zinc regeneration.

This experiment will be used to determine optimum  on-off intervals to maintain zinc regeneration and avoid zincate formation. Pictures will be posted as soon as I cut them down to proper file size.

Thanks for your interest.

Hi Chris (Tacmatricx ),

The system seems to be running very smoothly right now. I don't see any evidence of zincates yet, and it is sooooo nice not having to switch the power on and off by hand. If I need to go back to the two zinc electrode system then this unit will do all the switching for me. I also think the shorter switching time is better for the zinc regeneration. It looks clean so far, nice zinc regeneration, although I still don't think enough oxygen is coming off. The hydrogen production is good so the oxygen is going somewhere.

Thanks for your interest.

I ran across a method for making NaOH and KaOH at home from salt solutions and electricity.If anyone is interested please PM me.If you have kids or pets at home I recommend you don't make these at home.I have a friend whose cat knocked over a jar of liquid(baking soda solution).He was lucky,it just created a mess that time.But if it had been a base or acid it would have been a lot worse.Also NaOH at least (or KaOH) can be bought in the dry form from home depot or Lowe's in the drain clearing section of the store.
My radio shack does not sell etching solution(Fe Cl3).So I guess I will get some HCl and iron together and jump start the iron experiment I want to do.Triffid
