Large Salt water battery ideas and questions

you could also use a cramped up bundle of copper wire half-submerged in seawater or pressed against sponge for maximum air exposure.make sure that the wire bundle is all electricaly connected in a straight line before bundling and make sure that the insulator coating is all burned off the wire completely beforehand.

how about a bundle of copper pipe, riveted together with copper rivets and etched, half submerged, as you said, and twice the size of the aluminum anode? this is fun, and instructive

now a plan is coming 2gether yes indeed.try find pipes that are pencil-thin and bundle them.we want maximum copper/air/electrolyte exposure.pipes slightly pressed onto a sponge or towel will allow air to creep at an angle.

try doing a spot-test using bundled wire half-submerged and tell us if you get improved result @mungo.im realy curious if the theory will match practicality.use normal appliance cord wire,throw it into a fire to charcolize its rubber coat and simply bash off the charcoal pieces,they will fall off like glass,scrap dealers do this all the time

Experimenting with chemical voltaic cells such
as the Saltwater Battery can be great fun and
an enormous learning experience;  but when
one realizes how little energy they're capable
of producing for all the work that goes into them
it is sadly disappointing.

These types of Voltaic Cells are great for emergency
use to energize low powered devices for a short
time, but when more substantial power is required
the ubiquitous lead-acid battery with a suitable
charging/desulfation device (solar or wind powered
or both) is hard to beat.
