Fausto:

Hooked up my original cell I made a month ago to a 100 ohm load just to see what it would do.  I made it the same way but no cement.  Made from 1.5 inch by 4.5 inch long thick walled aluminum conduit and a 1/2 in copper pipe.  The graph is close to other one but I see it is curving down a bit.  It looked almost like the one I have been posting at first but it is at .661 volts and curving down.  Not sure where it is going at this point.  Will see tomorrow.  Have a good evening.

4Tesla:  Yes it will rub off real easy.  I only let it dry for about an hour.  It will take a couple days other wise before it drys to that level. 

Here is my graphs for this morning.  I included the old first cell with just the sodium meta silicate pentahydroxide and no cement.  But the aluminum cylinder was treated with the oxide layer.  It was made over a month ago and has been setting on shelf.  I was surprised to see that it functioned almost as good as the latest cell with the larger number of plates.  So we will see after time as Fausto has said.  If any one has a better idea of how to get a thick layer of oxide on the aluminum please share.  I originally was going to try the powdered aluminum oxide but wasn't sure how to get it to stick on the aluminum.  Maybe wetting it with water and forming a past then spreading it on like butter then letting it dry may work.  I might try that with some flat plates for simplicity sake.  Will have to purchase some though.  The graph on the older cell doesn't show it but it started out at 1.25 volts.  I will in the future have to let the graph run for a little while before connecting the load to reflect this.  I connected the load almost as soon as I started the graph.  Just FYI.

Fausto:  If you look at the bottom of the graph you will note the file name.  The multi plate cell which Was the original post shows crystal cell 1-9 which means 1st cell 9th picture also note the run time above 200k.  The very last graph of the last post at the bottom you will see aluminum conduit 1-3 this is the old cell I made around a month ago with just the sodium meta silicate and no cement.  Thought you might be interested in one of the older cells.  I was!  And yes I did bump it.  It fell over on the table while I was cleaning up and making some room to work.  Sorry.  Very observant!  Not really going to post much on the conduit cell.  Just wanted every one to notice what kind of success you can get using the sodium meta silicate pentahydrate. Thanks for input.  I am trying as we speak some other ideas of coating the aluminum.  One last thing.  The aluminum conduit is about 1/8 inch thick.  Would take a while to corrode this one to nothing.  Do you think?

David

Fausto:   How do you get so much done on so much testing if you have to tie up a computer and a meter for over a month plus bench space.  I have two computers on by bench with two logging meters and am seeing the restrictions of space, equipment and time.  My hat goes off to you!

will try to do better to identify my graphs!  Thanks.

David

Oh good about the identifications (I missed those numbers). 1/8" of oxide is indeed a lot of things to corrode BUT i had Magnesium bars of 1" tick and they vanished .   


I will try to build one of your cells.


Concerning testing, yes you are right, very little space and lots of testing. What I do is very simple. I create a new formula and build 10 single cells (2 metal plates only). With each one I try in groups of 2 different sealing mechanisms and different water feeding tests. One cell of those of the 5 groups I put on the meter. Usually the one not sealed so I use it as base-line.


The graph runs for a week which gives a sense of where it is going. Than I switch to another cell on the same group to the graph and starts measuring only with the meter the other cells and the one I just removed from the meter.


In one month I will be able to find out which one is with a better probability of succeeding.  The graphs are the key. After looking at hundreds and hundreds of graphs you start having a very good intuition of what is going on.


Next step is (by 2 week) I started another formula or physical different structure based on the results of the first and second cell of the same group. So now I have always 5 groups running in sequence. This allows me to quickly move towards a better formula/physical structure. If I see something really cool but no graph available because the other tests, I do it by hand every so often measuring with my 6 digits meter and putting all in paper.


So basically I have an empirical group of 5 cells recorded. A few, usually another 5 single cells, spawning from those 2 first week cells and keep in paper. By one month you will certainly have enough data to change ONE PARAMETER ONLY on the formula or physical structure, NEVER more than one parameter.


So you have it, I have lots of time at hand because I am a "batman" that does not sleep until 2pm. Now being a cab driver (used to be a software engineer) I have even more time because I work in the nights only.


Every cell has a name/number/formula/date and a hint of what I expect. You can collect lots of data like that.


This is one of the reasons I opened a fund with the hope of being able to buy more laptops (cheap ones) with more meters/graphs, more 6 digits meters and more physical lab equipment to improve the quality of the chemicals build.


I also have a 500x micro-camera that connects to the computer where I can see at a very good level the metal corrosion and its interaction with the crystals.


One EXTREMELY important thing is to OPEN all these cells each month but not the super running well until about 3 months later or when they die.


You got see my "cemetery" of cells, it is gigantic. I don't know how I will recycle those metals.


Fausto.

Fausto: 

        Thanks a lot for your explanation of how you test your cells.  Wow that is a lot of work.  So one other thing.  How do you pore your two plate cells.  Do you have a mold, you put them in,  pore them, then remove?  I have been wanting to figure out something quick and dirty so as to save material and make it easier to tear down and inspect.

I bought my radio shack meter off of amazon for 18.00.  I paid I think around 30.00 at radio shack for the first one.  It is brand new and works ever bit as good.  I think it is an older model but who cares.  I think it uses a 9v battery and the newer model I bought at radio shack uses AA's.  The program is the same so I would buy the 18.00 if it were me!

David

I really like the software.  I wish there was a cheap desktop version that uses that software.

Edit: I found this adapter.. the 9v version would be good when used with this.. no need for batteries!
