IB2,I like the idea of using soda straws as battery casings.triffid

If I were a guessing man and sometimes I am.I would guess that these crystal batteries that we can make in our kitchens and home labs can operate at less than one percent efficiency.That could mean in theory or at least in my dreams,we scould be looking at a 100 folt increase in power for these devices.triffid

Ok tomorrow I start connecting the wires in my 30 cell panel.Today I bought about 25 assorted LEDs to play with.This time I worried about too much power.(burning them out)If I'm not careful.Any way I measured my Cells I made last week and they are about the same.No drops in voltage since the last readings.Best one is 1.06 volts and the tin can lid cells(mg) are holding at about .8 volts easy.The tin can lid cell (copper plated zinc disk) is reading .28 volts. triffid

  Triffid:
   You don't need to worry about burning out the leds, as there is practically no current, as mentioned before, even less than a single AA battery would have. 
Once you connect the leds as the load,  the voltage from your cells will also drop to about 1/4 or so, of the original unloaded voltage.
   Good luck,

The glue cells dried pretty well but since these are the ones I have to stir.I found some really weak ones plus I assumed my aluminum duct tape was conductive(it was not conductive).Since the voltages were not adding up for ten cells I checked the conductivity of the tape I was using and found it was not doing the job of connecting my cells.We all know what they say about assuming stuff.In the process of pulling the tape off of about ten cells I broke the leads to two cells.So I did a reglue on those two.(a redo).I then added more glue to the other eight.
So now the whole thing has to dry again for 48 hours.I need to make some conductive glue.so I need to find some powdered graphite and make my own conductive glue.
I did manage to connect some cells together anyway and got a voltage of almost two volts.But not more.Even with three cells in series.






I assumed something and it made an (...) out of me.Sorry People.I will try again in another 48 hours.triffid
