DIY ACID FREE CARBON BATTERIES

[Bizzy]

Observation: @all - please respond with your thoughts.
The magnesium carbon cells powering my little solar lights, Old one sealed using Epsom Salt and the new one uses plain water.  The plain water cell seemed to be dropping current faster than the Epsom Salt cell.  A wind driven rain fell yesterday and rain-water got into the plain water cell.  Last night the cell gained strength and the morning the cell light was brighter than when I made it.  Why would rain-water be better than tap-water?  Any thoughts?

Hi Brad
It could be one of a couple things, so i thought I would throw out my ideas for others to comment on or to add to:
First it could be simply that the cell needed water and the extra water helped to "recharge it" I know it doesn't actually recharge it  but it gives it the added moisture to operate. If that is the case build a simple cell run it and add water after a few days to see if that helps and has the same results.
The other thing it could be is that the rain water has a slight charge  to it it. Nikola Tesla proved that the atmosphere is charged and that only makes sence that water as it falls would collect some charges on the way down. If that is the case it could be that it added the charges to your cell.


We are still working to clean up my parents house and hope to be back in the tinkering room this weekend.

For anyone interested, I have placed a step by step guide in the download section for the conduit/carbon/copper battery.

@all
I fully intended to do research last night but, instead I played with a basic joule thief and the Carbon/Copper/Zinc battery.  What great fun.  I could not light a 5mm LED directly from the two cells.  With a basic joule thief the two cells produced a very intense light.  I could light with as little as 10.7ma and the pot used at full on would consume slightly over 50ma.  I need to find the sweet spot where the cells are not stressed.

Have fun!

Hi B_rad great work nice nice. What is Alum? Aluminium filings?
Thanks

@guruji
Alum: food grade found in the spice section of your grocery store.  This is used in pickling recipes as a preservative to maintain fruit and vegetable crispness.  People have been using alum in the restoration of lead acid batteries as it breaks down the lead sulfate that destroys lead acid batteries.  Many think alum has mysterious properties that preserve the anode in a battery and claim that early lead acid batteries used alum, but was discontinued because the batteries would not wear out.
