Free Energy | searching for free energy and discussing free energy

  Hi All,
 New here. This is an idea I've thought of before but haven't thought it worth much or even possible.
I figure in a forum like this, maybe someone could clue me in if it's even remotely possible.
 The idea is fairly simple, use something like a CRT to act as a cathode in water. What would be
different is instead of passing regular current through it, it would be a specific frequency. You know,
trying to use a little less energy to achieve the same result.
 And then, at the same time, be passing a high frequency current through the cathode as well. I mean,
in a perfect world, one frequency would polarize the water against the cathode while the more excited
high frequency comes along and basically splits it releasing energy.
 I've done electroplating before so have some basic understanding of this type of stuff. But wouldn't
know if this is possible or even how something like this would be set up. How to put it ? I have an idea
but not the brains to know any better
