I tried a variation of your sand/carbon 50, 50 mix. And at first I got not much difference than just the carbon gives, so I let the cell sit. This little cell is a capacitor can that is only 3/8"by 3/4". But now, an hour later it reads 1.4 volts and 1.5mA. So, not bad for such a small cell. I did not wash the salt out of the fresh wet beach sand, just to see what happens this time. At first it jumps to about 2.5mA then back off to 1.5, so very interesting results.
Thanks for the info,
