Thinking of acoustics....If the hemispheres are very accurately machined then any ultrasonic excitement of the surface that is symmetrical will form waves that collide at the center of the device. Very large pressure will be generated similar to the collapse of a bubble. I know of a fingerprint reading technique that uses a partial half sphere emitter of ultrasonic energy. This allows reading of the finger shape very accurately even through rubber gloves since the energy is focused to a tiny point.
Maybe the extreme pressure can lead to a form of LENR that generates excess heating in water. I wonder whether the effect is due to ultrasonic or RF activation. A 'resonator' could apply to both and the frequencies used for ultrasonic generation are within the RF range. I also would assume that the structure has an RF resonance, but it would definitely posses an ultrasonic one. If the Q of the ultrasonic resonator is high, then standing waves would form within the structure. A moderate amount of drive energy could result in a far larger amount of stored energy in this configuration. Perhaps this type of system would behave as a cavitation generator on steroids.

The mention of an RF resonator in the video has interesting implications if this device actually works. The spherical shape of the unit suggests that it would have resonances at radio frequencies within and some might be closely coupled to the water molecules or atoms to which they are composed. The heating energy must arise from some mechanism since the device appears to warm up at a rate that far exceeds the possible output power of the 9 volt battery. Two (hemi)spherical electrodes with water in between would form a crude electrolytic capacitor which, in combination with attached wiring, would form a tank circuit. The resonant frequency of such a tank circuit would likely lie in the RF frequency band. Thus any anomalous energy that fed into the tank circuit could produce RF emissions from the wiring.
