    Jesse. Good cite! I might point out that this reference medical
    insrtuments and ends with: " However, the intensity threshold for
    cavitation in man is much higher than that obtainable by commercial
    instruments (approx. 1 kW/cm2), and even though thermal and
    mechanical effects may act synergistically, no confirmed bioeffects
    in patients (or operators) have ever been observed. " 

    I wish I knew how to compare the volume of our cleaners with the
    references to Watts/cm^2 as the volume of our cleaners would be best
    described with Watts/cm^3.
