This is not a bad idea. The speed of sound in water is about 1500 m/s. A 5 mm separation distance would imply a wavelength of 5 mm, which in turn implies a frequency of about 350 kHz, which is certainly in the ballpark. > > >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.

Especially if the RF resonant frequency matched the ultrasonic one? (Tunable with a variable inductance coil in the RF circuit.) Years ago I suggested that sono-fusion might be mediated by Hydrinos created in the plasma at the heart of the bubble by the action of O++ as a Mills catalyst. Mills has recently suggested (CIHT) that "nascent" H2O could also function as a catalyst. (Single water molecules catalyze, where molecules bound by Hydrogen bonds in a liquid water don't.) The high temperatures found in the bubbles would be more than sufficient to vaporize some of the liquid water, creating individual molecules, and also some free H atoms for them to catalyze.
