Hi Jim 0216, I don't want to get too far off the Oroville thread… But to answer your question: A standing wave is a stationary condition used to describe the non moving center of the expanding and collapsing single bubble. The bubble is introduced into an ultrasonically stimulated chamber such that the sound waves in the liquid in the chamber focus on the gas bubble. The collapse is so violent the energy released causes light and a thermal intensity of four times the temperature of the Sun. Since the Sun is a "fusion" reactive process, this is where scientists jumped at the excitement of the possible use of "sonoluminescence" as a key to new "fusion" based energy technology. However, the problem is that nobody has been able to come up with energy equations that explain this effect. Scientists have engaged in arguments over each other's theories - calling the others' theory "crazy". Oh what fun science can be.
