You are right about the way a surfactant works, George.
I found a video that shows the effect of sound on water in an open bowl.
http://youtu.be/q19p1df2tWEIn school I took Home Ec, where I learned about fibers. They require some pretty intricate combinations of warp and weft, or cord manipulation. My later training dealt with materials like steel and metal alloys, ceramics and plastics, and my worklife required hands on transformation. Those materials are all susceptible vibration and frequency to change their state. Why not water?
Sounds too good to be true? Perhaps so. But Tesla had a concept that Rockefeller was willing to bankroll, until he found out there was no way to make it pay off.
I would be willing to invest a few dollars in a small box that attached to my hose and put 24 volts (that would be 4 D cell batteries or so) of radio frequency into the water. Instinct says it makes the molecules smaller, increasing the absorption rate and permeability.
