The researchers, led by UW-Madison geologist and crystal specialist Huifang Xu, grew nanocrystals of two common crystals, zinc oxide and barium titanate (quartz is just as good ), and placed them in water. When pulsed with ultrasonic vibrations, the nanofibers flexed and catalyzed a chemical reaction to split the water molecules into hydrogen and oxygen. UW-Madison Mechanical Engineering Professor Xiaochun Li lent theoretical and experimental expertise to the ultrasonic vibrations part of the research.

The answer to the dilemma is ultrasonics. It is an experimental fact ultrasound of
600,000 cycles focused on a vial of water can cause it to boil. This means that sound of this frequency
disintegrates large quantities of soft electrons in the water. The sudden release of hard electrons produces
tremendous thermal agitation of water molecules. A DC ultrasonic transducer attached to the tube would produce
sufficient free electrons to be entrained for the unit to have almost unlimited output potential. The tube functions
like a sounding board.

Pulsed DC - Wikipedia, the free encyclopedia
Pulsed DC or PDC is the form of wave produced from a half-wave rectifier or a full-wave rectifier. Full wave rectified ac is more commonly known as Rectified AC. PDC has some characteristics of both alternating current (AC) and direct current (DC) waveforms. The voltage of a DC wave is roughly constant, whereas the voltage of an AC waveform continually varies between positive and negative values. Like an AC wave, the voltage of a PDC wave continually varies, but like a DC wave, the sign of the voltage is constant.
