    and i looked into it more, a backyard setup with secondhand materials is only powerful enough to light up an LED light...
    there's a whole science behind it on how to get the best voltage/amps out of 'earth batteries' as they call them; apparently they used to power the telegraph system entirely through 'earth batteries' back in the day.

    if you wanted to charge a car battery, you'd probably need to have like a whole acre of copper and galvanized iron/steel poles set up with wires running everywhere, and would somehow need to figure out how to increase the amps as to actually make a dent in a car battery. I'm not an electrician; perhaps amps and volts can't simply be added together to higher values.

    if you want higher voltage you wire in series, if you want higher current you wire in parallel. also, voltage = (current * resistance), current = (voltage / resistance), power (watts) = (current * voltage)

    something tells me the earth has a pretty high resistance.
