I think Electrons @ Protons are abundant in the air and the kelvin water drop gen extract them and store them on the surface of the tin cans.i think all static generqtors gather static energy from the surroundings. Water falling cqn collect such energy. I think thos energy cqn cause levitation of ver heavy objects. A massive amount of storage could float a capacitor or lifter. The energy osnt created or destroyed but extracted used qnd gav back. Water does not hold the protons and electrons the water drop gen extracts but water is a carrier of it. Something has to carry it in the gen. Take a charged baloon and styrofoam pellets for ezample. The baloon will move the pelletes, or will it??? Or maybe it is the storage of electrons or even protons thay does thos. If this pull and push can do this y not pull water apart woth no frequency. SORRY FOR TYPOS IM ON VERY SMALL CELL PHONE. a positi e cloud and a negative one. Androide or microsoft cant ever get anything roght.
