Hi there Bio-people!
I've made a pedal water pump, thus for filling a water tank... Quite new, don't have statistics yet, but only that 20' is not enough for pumping 500 liters... but I believe almost...
I'd like some help on how could I do to get some extra advantage of the excercise, since I have to do it anyway, in order to help charging the batteries (usually charged by solar pannel).
Thanks a lot, and here a pic of the stuff.
