Well I don’t know I’m just speaking on my intuition. From my
experience as a plumber and
water operator, a lot of old cisterns were lined with a sheet of copper. Copper was said to prevent algae and mold. I don’t have a true experiment per say but I started cuttings in two locations. One with magnets all around the pots and a small copper pyramid I made. The other pots are just control. Both by a window sill that gets afternoon sun.
The cuttings with the magnets are flying and thriving. In constantly filling with cup with water. The control hasn’t shown leaves yet at all, it’s been about three weeks. The paw paw was along with the magnets, she took a long while to sprout but she finally started showing leaves. That pawpaw mind you a very slow and steady plant.
I agree the earth is a giant dynamo, think about this…you have the whole ocean full of water. but you need to harness the water and refine it to use for what you need, you could increase or decrease the pressure etc. you see what im getting at?
I don’t have the answers or could prove to anybody that this is legit but these are things my intuition has guided me to.
