I have read there is a way to dissociate water without use of an electrolyte by means of high voltage that overcomes the dielectric constant of water. Would it therefor be possible to economically retrieve water from any depth well by dissociating the water at the bottom of the well into hydrogen and oxygen gas...then let it rise to the surface in separate tubes or hoses without having to expend the energy to "lift heavy liquid water" from deep wells. Once the gases reach the surface, they can be recombined to form instant, pure water requiring no treatment or filtration. As a bonus, this recombination could power an engine....or, a portion of the gases could run a fuel cell to aid in the creating of the dissociation voltage (stepped up by an alternator / coil) and so allow the process to continue. Has anyone ever tried this approach? Would the net energy expended to this be less than the conventional means of pumping water from a deep well...and then have to purify the result?
