Yeah that's great.
And had we been talking about induction heaters, it would have been on topic too.
But the thread is about cavitation, not induction.
Just to throw my 2 cents in:
- I don't see what is any more remarkable about the evolution of a shrimp which uses the
sonically induced cavitation of its naturally surrounding medium to produce a compact
shockwave that in some cases is strong enough to actually produce a minuscule plasma
flash, than there is about a bird which has evolved to use aerodynamics and currents in
its naturally surounding medium to give its body lift and speed. But then again, there's
many people who seem to have trouble understanding how evolution can shape the
various remarkably complicated mechanisms that we like to call organisms.
- Am I the only one who smells something fishy when people start talking about
Thrapp and his "Amish scientists"? Come on now. Amish scientists? That's almost
like vegetarian butchers or Jews eating bacon.
- Cavitationnally induced fusion is an interesting concept, and if heavy water were
used instead of normal water the plasma inside the compression bubbles might
even be used to fuse deuterium (and/or tritium) into helium. Experiments along that
road have been done (are still being done?).
Problem is, how would we get the energy out? A possible way would be to "simply"
have the miniature fusion reaction dump its energy into the surrounding water as heat
(or mostly heat), then use the hot water to run a turbine or generator.
And that is an idea not much unlike the Chain Reaction movie shows.
So what would we need to do this?
Well, a sonoluminescence setup, so that's what, a quartz tube with pure water in it,
and a speaker arrangement with a freq gen so the right frequency can be pumped
into the tube, and then of course input and output flow valves with a connection to
the generator or heat exchanger.
Then we need a generator that can run off the hot water.
And we need a supply of water to pump around, and preferably heavy water.
Where do we get heavy water?
Anyway, get all that set up water and air tight (you don't want to accidentally
inhale heavy water or tritium vapour) and get the sonoluminescence going,
and with some luck you can actually fuse enough of the stuff to produce
excess heat => energy.
