using some form of radio frequency?

As a Marine electrician, part of my workday included putting Fork Trucks on charge. Every recharging station always included a vent system to insure that the hydrogen is vented away from the batteries so that there was no chance of fire or explosion. Because of this, I always knew that I could get Hydrogen and Oxygen, just by "cracking" water. I have tried to study all the various ways of cracking water, and it seems that the ones that use direct electrical systems to charge plates immersed in the water, require high amperage, and thus plenty of heat. Then I saw the story about the guy running through the radio frequency spectrum and how his "salt water" caught fire. From science studies I know that everything vibrates or has a "resonate frequency", so I knew it was true. I just don't know how much power is needed to run such a frequency generator, dedicated to cracking the water. But it seems like a "cleaner" way to go. I am kind of lazy, so I don't like the idea of "reinventing the wheel" if someone else has already done all of the work. I can do a fair amount of "manufacturing" myself, but if I can buy something already built, for a reasonable price, I will go ahead and buy it. Like buying a "Grand Slam" breakfast at Denny's instead of cooking at home. I was also an Auto Mechanic in the 60's and 70's, so I know a little about basic automotives. I don't pretend to know everything about present day automobiles and their engine control systems, not by a long shot. My planned experimental vehicle is my 1990 F-250 Ford Truck. I do believe it has fuel injection, so supplying "Brown's Gas" to the intake manifold plenum chamber seems like the correct way to get it into the engine.
So far, all I have done is the Internet search for information on the subject.
