Tried your idea of using more copper in the cell last night.  The first cell in the image below reported 1.13v. Had some copper foil that I lined the cell with.  The second cell in the image reports 1.09v.  This cell is 11 days old and has 120+ run hours on it.  The only other difference between the 2 cells is the first cell is plain tap water ond the second has a weak epsom salt solution.  I will continue to monitor both for best results.  I have really enjoyed this project - the first cell built lives on the patio and is great for relaxing at night.  Just enough light to enjoy a beverage without drawing attention to yourself.  Magnesium fire starter and carbon.

Update on the penny cell battery.  This battery has 120 plus continous run hours and still going strong.  Without using carbon in other build, I would have already started pulling LED off.  I have not had to with this one.  Will continue to monitor this build.  The picture was taken after the 120 hours of run time.

Update on conduit cell battery.  This is my pride and joy build due to the simplicity, and cost.  The six cells in this battery took about an hour to build and the consumable part (conduit) cost less than fifty cents.  All other parts of the battery are reusable.  This picture was taken after 120 plus hours of continous run time.
