I don't think you can get away from the fact it takes energy to break water - more than you get back when you oxidize it. That is why hydrogen is an energy transport material - not an energy source. Gonna be hard to compete with hydrocarbons where there is a huge energy output from simply isolating them and getting them to combine with O2- the energy has already been put in them.
I don't get this comment: " wasteful vibrational movements found in the environment." How is that related to an ultrasonic cleaner which clearly has to be plugged in the wall. It all sounds very anti-laws of thermodynamics at first blush.
