actually, i conducted such a project back when i worked in Health Distillers. one rod is made out of aluminum, while the other one out of still. the whole point of this process was to break down the h2o molecules to divide the water from any other pollutants in the water and make them visible. this process is called "IONIZATION", check dictionary.com if u have any doubts.
anyhow, this process isnt a permanent break down of the h2o molecule, just a temporary one to make pollutants visible, and only some pollutants.
also, as "cheap and easy" as it may sound, that little apparatus, which was around 10 inches tall and could be fitted into a normal drinking glass, it still cost A LOT of cash to make. i forgot the exact amount, but it was a very expensive little thing. not to mention, a bit complicated to make. constant maintainance was required. i had to clean the rods before every single demonstration, after every single dip, and after the demonstration was over, and as soon as i got home. else, the rods would oxidize.
now that we have that clear, lets talk about water costs. first of all, pollution is found in pretty much almost everywhere in this planet, and not just that, but contamination as well. for those of u who didnt pay attention in science class, contamination is produced by nature itself, while pollution is created by us humans. its normal to go to the cleanest spot in Earth and find animal crap all over the place, and thats called contamination, but still, it makes the water dirty. lets not even mention pollution, cuz thats just plain undescribable. in order to clean water, it is a very long and sort of expensive process. most companies are required to have some sort of distillation system, as well as atleast one other process that is mandatory. there is a third process too, but its not mandatory in some places. the machines, the electricity they use up, and all the piping systems and containers and such cost alot of money. not to mention, it all gets inspected for fesces, CAL, clorox, and other materials that are harmfull to the human body, or that just plain make the water impure. this is why water is not cheap, and never will be. keep in mind another thing, fresh water reservoirs are extremely small (very sure it wasnt more than 8% of the world's total water), and rare things = $$$. cleaning salt water is an even bigger pain in the ass.
