Large Salt water battery ideas and questions

yes but dont throw in soap as it will form scum on the anode.throw in caustic soda,it will dissolve zinc hydroxide.

I meant that metaphorically, but I take your meaning.

Anyone have any idea how much of a problem the O2 content of the electrolyte might be?  Is surface absorption of atmospheric O2 adequate, or will it eventually be exhausted by the anode?

if you use caustic soda you may just be able to not even worry about air anymore @mungo because of the drastic increased wetting ability at the cathode,the H2 bubbles should seperate at a steady enough pace to give steady current.your copper pipes must stand totaly upright to allow bouyency to lift bubbles up and away.the voltage will be around 1.1-1.5 in this setup and should be quite stable.play with raising and lowering the copper to half-submerged and fully submerged to see if power improves.

these tests may have to go youtube in the future

dont use brass as your cathode.brass is 40% zinc.use pure copper
