I don't understand how random movements could be translated into useful ultrasonic movements.
However, where is the anti-laws of thermodynamics? I think I've read that cracking water with electrolysis is about 50% efficient. Can this be made more efficient, somehow? For example, in many chemical reactions, use of a catalyst reduces the temperature needed or increases the rate of an ultimate reaction. That means, to get that ultimate reaction, less energy has to be used. In cracking water we're not talking about a catalyst, of course. But could ultrasonic vibrations could have a similar effect?

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.
