Success with stainless steel pot scrubber
@Dragon
I had success with a stainlees steel pot scrubber and aluminum. I tried it with a magnesium firestarter stick and, like you said, the Mg got eaten very fast. The power was good though and I could even run my little "Bobin Bedini" SSG off it nicely. The stainless steel scrubber/aluminum worked best in a saltwater electrolyte that I tried. An aluminum soda can or just some aluminum foil worked. Next time that I'm down at the boat I will get some sea water and try that. A chunk of zinc and stainless produce good results also. I don't know what alloy stainless steel that they use in those cheap (3 for $1) scrubbers but it works great. I'm thinking that a nice chunk of aluminum (or zinc) and one of these SS scrubbers burried close to each other in the ground might make a very long lasting battery. A couple of flatened Al soda cans might even work.
The "earth battery" that I showed in my last video is going strong and is still driving the little pulse motor. After I made that video I unrolled that speaker wire so I could run the wire along the wall and out of sight. That didn't seem to make any difference.
