Well, the thing hinges around the difference between just injecting energy, the way a microwave oven effects a potato, or doing something more such that hydrogen bonds are released because of resonance to a frequency (or its harmonic). Understandably, there's no discussion of the frequencies involved, or a mathematical discussion of the harmonics relative to the dimensions of the bond sites. Dunno if there is something going on there or not. The video I saw did not either describe the time and power of the RF output. All I saw was evidence that the test tubes said to contain water/salt water were apparently leaping into flame as though they contained hydrogen or some other flammable gas.
