Steam fusion

While at work the other day I noticed that when steam is injected into water it rapidly condenses back into water creating a huge amount of compressive force onto a very small point in the water additionally I found that by changing the position of the steam hose, temperature of water and/or volume of steam within a 5 gallon pail that the effect can be magnified greatly. The above experiment is of course not very "clean" and may be subject to other effects but it does show that the process can be optimimized for maximum efficiency.

This led me to thinking about a kind of lobster or somesuch critter that I had heard about on Discovery or Animal planet that had an attack whereby it would move it's claws very fast and in such a way that it caused the water near its prey to cavitate and when the bubble collapsed it did so with such force that it created extreme temperatures lasting for only (if I remember right) a trillionth of a second with temperatures around a million degrees.

So I thought why not replace the water with heavy water dissolve some lithium or boron 11 into it and see if it is enough to drive IC fusion. A more concentrated fuel to try boron 11/deuterium compound? Not sure how it would hold up to being evaporated or if its molten state is friendly to the above method.
