Lesson: Different Designs for the Earth Battery; High Amp Earth Battery Design [1000% Increase!]

There are a few companies that are using earth batteries to run low power remote sensors and monitoring equipment. that would be one use. other uses could be to run low power items such as Led lights, buzzers, lcd clocks, and a variety of other small items with lcd screens. they easily run battery powered calculators too (so that means they can run small computing devices). this particular big battery cell could even run my solar powered AM/FM radio. i calculated i would need 10 of these cells hooked in parallel but that could be done fairly easily.
To keep it charged you just keep the soil wet. as it dries out the power will be less, but just add more water and the power goes back up (or just cover the top making sure the water doesn't evaporate [airtight]). Adding a lid to any of these style batteries stops evaporations and oxidation of the material keeping it good for much longer periods of time, as long as the charge stays wet the battery will stay charging. As long as you have a airtight lid that doesn't evaporate water these battery's will stay charged forever giving the same charge for life.
