Working Air Battery

Sweet
One way to dramatically reduce the cost of the cells and maintain the same performance is to use PVC instead of copper pipe.  Strip of a foot or so of insulated wire and pack your activated carbon so that the wire is embedded in the length of your cell. 
1 day we should bury these cells in the yard and see what impact this has.  Rainwater, lawn watering, and morning dew might keep these cells juiced.  Good work!

Hi B_rads about the cell you're mentioning so you don't use magnesium rod? Just PVC; carbon and copper wire?.
Thanks.

The sacrificial anode can be a metal of your choice.  I like zinc because it is soooo cheap.  Bizzy is using magnesium.  I suspect aluminum could also be used.

Hi Brad
Yes you could use any metal for the "sacrifical" metal as long as it it differant than the primary component which is carbon. However there is also work being done with same metal batteries in another thread as well.

I posted this about 3 years ago on the earth battery topic.  This chart shows that it makes a huge difference what metals are used.  This is why I chose magnesium and carbon a long time ago.  They are the cheapest and easiest to get metals that give the most difference.  I frequently get over 2 volts from my earth battery which is still running after all of this time.

I hope this helps.

Good morning
The following are the results of my latest test. I wanted to know if granular size of the carbon made a differance. Below is a picruew of a single cell with activated carbon just as you would buy it at the store.
