Earth batteries put off about 1 volt but wired together they provide more voltage, it's essentially free electricity as long as the dirt stays moist. Mining litecoin isn't very profitable unless you have free electricity because of electricity costs. I need to know how to do this safely and where to get the parts fairly cheaply as well as how to build the setup. It doesn't have to look good or be fancy. Also I don't want too much electricity going into the mining hardware enough to break it. I'm also open to using solar panels if they don't cost alot, like making them with solar paint for example. If there's any other cheaper form of electricity that's fine too. I'm just trying to do it with free electricity as using a power company costs about 90% of the mining profits. I also have a large creek in my back yard that can support a water wheel for generator electricity. The cheapest electricity is my goal here. I only have about $180 to use on this. That includes the cost for the miner(s) and I'd like to be mining at least $20 a month worth of litecoin starting out. I'm also open to mining pool information but that's optional. All of this required information can be found on the internet. Thank you and have a good day.
