Very good observation, and very relevant
On the cell I am working on, the top of the mag gets mushy, because it has no contact with the copper, and the air also may have something to do with it also, although I submerge these types of cells totally under water most of the time
I have tried coating the top with crazy glue, and this seems to work fairly well
I have also poured in a thin layer of power steering fluid, and this seems to help with evaporation of the water and H2O2
Best of luck

Mineral Oil
Back in March I replicated the Crow's Foot (gravity cell) and learned that mineral oil was used to slow the evaporation of water. Since that time, I have been using this oil in my water batteries. Mineral Oil is a dielectric used in transformers and high voltage switches today. It does not conduct electricity and functions to displace water and air. Another thing I learned was to use insulated solid wire to connect the electrodes with below the oil and surface above the oil for connections. Additionally I use glue where the insulation is stripped from the wire to further seal from air leaks.
I prefer to use zinc for my negative electrode for several reasons. Abundance, easy to melt and shape to my designs, plus it has more electric potential than most other negative metals. It is a slow release, therefore, optimal circuits should be used. My local mechanic gives me all the used wheel weights I need and with my butane torch, I can easily melt these and form into rods, sheets, and plugs. You can also use U.S pennies post 1982. 25 pennies will make a fairly beefy electrode.
For great fun, set 3 medium sized cells in series in the sun and watch the power increase. The oil has a prismatic or fresnal effect and heats up the metals really well. I use these for charging secondary batteries and it works better than the cheap solar yard lights.
Very nice observation Ib, I have been doing this for several months now and am very happy with the results. I will not go so far as to say it completely stops the consumption of the metal, but it does have tremendous benefits.
Good luck guys,
Brad

Quick question about your latest video. I saw you discharge a capacitor in water, then you show that your pressure cell does not discharge in water and behaves differently.
That video shows comparing a capacitor to a pressure battery.
I was wondering, because I haven't tested this, what happens if you do the same test with a AA battery. I would expect that the AA would short out and run out of juice over time...but not immediately or within a couple of minutes.
What I don't know is how it would behave for the first 30 seconds or so, and wondered if that would be the same effect that you saw with your pressure battery.
Also, what happens if you leave your pressure battery for a long time in under the water, like 2-3 days or more?
The reason why I did this was that I work in the boat industry and I have seen boats get submerged. When the boat gets submerged so does the battery which gets shorted out by the lake or sea water and thus the battery goes bad. Yes a AA would short out over time but it depends on how conductive the water is. As for leaving cells in the water its not good, the salt substitute dissolves into the water and the metals corrode when exposed to water.

I made a new cell last night using Allwest new geometry and mix but this time i removed the salt substitutes. They seem to catalyze the reaction to the point of eating (oxidizing) the Magnesium really fast.
Without the salts and still using Carbon and H202 (peroxide water) it works very well without (so far) signs of corrosion.
With the salts, Mg becomes a soft grayish-whiteish color that bubbles.
What is really interesting with this cell that I did is that the Mg and the Copper are shorted together and therefore the resistance of the cell is very, very low and also increases the current output as the load resistance decreases.
This, I think, is very important because this is making a cell very strong since its internal resistance is very low.
Now, how this amazing weird cell works by being 100% shorted is a mystery.
Fausto.

Pressure battery not losing juice in water like a cap

Also regarding Volts, this is what I am talking about with this cell being touchyOriginally posted by plengo View Post@Allwest,
man I did a cell using your Mg enrolled on Cu but I also added activated carbon to the mix so that I can use it with a lot less water content and to my surprise the cell after dry is performing 10x more powerfully than all of my cells concerning current. Concerning voltage is not that much yet but it is increasing with time and so it is its current.
I am babled by this design since the copper is shorted to the magnesium and still produce power. I have no clue how this works.
I am using a tiny amount of alternative salt or salt substitute based on potassium, carbon activated and peroxide water very low level concentration and no extra water. The cell size is 1" high and the Mg is only 3/4 high and about 1/2 inch diameter.
Once reaction starts we have lots of Oxigen bubbling.
I will post a video very soon.
Fausto.
ps: using an Oscillator here is ideal since the voltage is usually at around .1v and .5v but current in my small cell is about 50ma constant and increasing as it dries. So overall the output usable power is greater than my other cells. The oscillator performs very well.
If it is that low, the cell is not fully formed yet, give it some time, or heat the copper on the Mag and place in liquid, you will have instant volts 1.60, and it should stay at 1.44 even when totally dry
Best of luck

Plengo,
Excellent, there are many more good surprises to come
Have you tried Lamp black instead of activated carbon?
Also to get more volts,
Wrap mag with copper wire
Leave a spiral out at the top
Paint copper with lamp black a little salt and moist
Place in a copper cap
Let the spiral touch the top of the copper cap
Add hydrogen peroxide to moisten and as you need more power
Best of luck

that is a very interesting experiment. I am replicating and indeed it is very powerful. I see lots of gases (as you show in your video). The question will be how long it will run.
I like the idea of the oxidation layer between the metals and the peroxide water, which I have used in the past too and indeed that one alone increases the performance of the cell.
I will keep you guys posted of my replication on that one.
Fausto.
The third day you will loose half the power you begin with, the one I am working on now reads 350 Ma, and when you start the meter to read it goes up to 550 Ma and stays on load, I believe the load is creating the heat that makes the Amps go up, add additional depleted hydrogen peroxide and it will go up from there
Best regards
Also, it does not need to be as long as the one in the video, you could cut the rod in quarters, and get 4 cells out of one rod

Hi Plengo,
Thanks,
This cell is very touchy, until the oxide layer is formed
To speed the oxide layer up, you can heat the copper right on the mag, and then stick in the salt- hydrogen peroxide bath
I have found out that, after you heat up and place in liquid, the water stays hot much-WAY longer than normal, I wonder if it is being thermally activated with the liquid and hydrogen being released
Best of luck

Very interesting recipe for the Mg-Cu battery. When you said salt and hydrogen peroxide solution for the electrolytic mix, do you mean a H2O2 water solution of food grade concentration of 35%, or do you mean a 6% concentration of drug store grade H2O2 solution? The mix should have some sort of water in it, or you just used salt with H2O2 solution?
1.6V 1Amp is quite impressive, I hope it can endure some days along, providing a continuous current flow without diminishing its power.
I suggest also the used of Permatex conductive grease to protect the Mg rod from corroding. But the H2O2 will certainly react with the grease.

I am still playing with the electrolytic mix
I use 35% solution, but add a teaspoon to the glass of water, you could probably use a 3% solution from drug store, with no water and have same affect
I try and use very little salt, as it seems to crystallize on the copper and reduce the power
The trick is to get the copper as tight onto the mag as possible, and let the oxide build between copper
Then the mag does not corrode as much, the copper will be welded to mag if done right
Higher concentrations of hydrogen peroxide does give this type of cell allot more power, I have had this type up over 2 Amps
Note: 35% hydrogen peroxide will burn your skin
Also, interesting findings on this, at the top of the cell, I widen out the copper coil, for several reason, (one, is when the copper gets a light blue oxide on it, it will absorb the hydrogen bubbles)
Best of luck
