"Using specific Radio frequencies does convert salt water
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.
