"Using specific Radio frequencies does convert
salt water to hydrogen."
Cite a source for that, it contradicts all known science.
You can "liberate" the hydrogen from
salt water, but in order to "convert"
salt water to hydrogen, you'd need to either start with salt water that curiously had the exact same particle ratio (electron-neutron-etc) so it could be
converted, or with any other ratio you'd
wind up with a partial conversion and then a bunch of waste products and possible energy (particle) liberation. Do the math, you tell me what is in your salt water and write a balanced equation showing the particles In it versus the hydrogen and other products OUT of it.
You cna convert lead into gold--but the
price of the required reactor or particle accelerator makes it a damned expensive way to go gold mining.
