I bought supplied , Epsom and cotton , the cotton should improve the stability , and Epsom boost the amps , i will try a 3 layer stack , to get 1.5v out of it .

My plan is to use the battery has the core for a Joule thief circuit ...

@all
Just some random thoughts about these batteries.
Object: Best methods to optimize output and minimize fuel consumption (Anode).
What is the best Cathode/Anode/Electrolyte combination?
What is the simplest build method to replace fuel source (Anode)?
Seek the most environmentally safe combination of materials.
What is the best use or storage method for output from these batteries?

I agree with others that have indicated that the Cathode can be a more expensive part of the battery since it should have a very long life, and the Anode could be recycled waste â€" such as aluminum, galvanized nails, steel wire, etc.  For the Cathode, I am currently using an electric motor carbon brush 1 ¼”x1/2”x1/4” with very good results.

Thus far â€" if I were to experience a power outage, I know I can build batteries to power lights or a small radio.  This is a very comforting feeling.

For general info on batteries â€" I have found these references interesting.

I really like your build â€" I think you are onto something with this.

This fellow just subscribed to my youtube channel. He has a very interesting battery with instructions.
It uses the carbon from charcoal and it is in an aluminum base which is the anode.
He is getting 1.6v and 15mA because he uses clean potash (= cleaned wetted wood ash from a wood stove)
I am impressed... Talk about recycled!
Please have a look. All the information needed is on that video. It is a good job.

... and in the end he uses a garden light circuit (EE's jtc) for a light, so this is great for anyone who does not have access to a  toroid or for rainy days use with the garden light.

Not as eco friendly as the video “Jeanna” posted above.  However, this is a very easy to make emergency light.  Fire starter, carbon brush, hacked solar light, and 20% bleach solution.  The AA battery was removed from the light.  I also tried this with table salt (heavy toll on the magnesium) and the output was about the same. Runs for 2 full days before the light dims â€" stirring the electrolyte will give temporary boost. 
Love all the builds everyone is doing and all the ideas floating around.

48 days and still running.  ;D
After several days (10 maybe) I added 2-1x3mm red leds for a total of 3 leds.
I have not added any water, just let it happily light the leds without interuption.
I do occasionally check with a meter and it is consistantly putting out 1.57v to 1.62v.
