Sooner or later we will have to consider using our own bodily wastes as sources of material.It could be toenail clippings,hair clippings, or fingernail clippings.Or dirty bath water with epsom salts and dead skin cells for instance.Boiled down this bath water could yield crystals.In outer space we need to be able to reuse everything.I am not trying to gross anyone out.But lets keep our minds open to these possibilities too.That said I have been looking at my aspirin cells again.In these cells the magnesium strips have not corroded.But the copper has a nice green color in 4 out of 6 cells.These cells were sealed with wax on 2/15/2012.Each one is still producing a voltage ranging from 1.22 to 1.34.I want to remind everyone that starch was the second most common ingredient in the aspirin tablets I used.The other cells I made since then have corroded the magnesium strips and the copper electrodes.triffid

PB,looks like your latest page on magnesium reactions explains why my aspirin cells do not corrode the magnesium. Sodium salicylate is a sodium salt of salicylic acid(aspirin).And there is no reaction with magnesium(sweet).There are other things on that list that will not react with magnesium.I need to look at it more.Thanks,triffid

Green color for copper too predicted by your page...                                                                                                                                                                        The solution turned to a green/olive green colour
Colour slightly darkened, but no precipitation or great change. A complex reaction here, perhaps.

PB,Your page predicts that tannic acid would not react with the magnesium but react a dirty grey brown color with the copper electrode.
I think you found a good resource here.triffid

tannic acid   http://en.wikipedia.org/wiki/Tannic_acid


Tannic acid is used in the conservation of ferrous (iron based) metal objects to passivate and inhibit corrosion. Tannic acid reacts with the corrosion products to form a more stable compound, thus preventing further corrosion from taking place. After treatment the tannic acid residue is generally left on the object so that if moisture reaches the surface the tannic acid will be rehydrated and prevent or slow any corrosion. Tannic acid treatment for conservation is very effective and widely used but it does have a significant visual effect on the object, turning the corrosion products black and any exposed metal dark blue. It should also be used with care on objects with copper alloy components as the tannic acid can have a slight etching effect on these metals.Tannic acid is also found in commercially available iron/steel corrosion treatments such as Hammerite Kurust.


Can be made from strong tea!For our cells!
