Hey there guys. I live in a state where we lose power quite often and I am going to be moving somewhere quite rural. I was looking into potential ways of producing my own energy and stumbled across an "earth battery." I was just wondering if anyone here has any experience with these/knows anything pertinent/can point me to some good archives to read over. I'm not very literate when it comes to electricity, how it functions, nor how to produce it, so any materials on that would be highly welcomed as well.
