sonarluminescence

I stumbled across this vid and didn't see anything about in a search, so I thought I'd share it...it's really cool.

Seraphina,

Very interesting video- thank you. I like the star in a jar idea. :)


In the spirit of extending external consideration to the group, the video summary is as follows:



Sonoluminescence can occur when a sound wave of sufficient intensity induces a gaseous cavity within a liquid to collapse quickly. This cavity may take the form of a pre-existing bubble, or may be generated through a process known as cavitation. Sonoluminescence in the laboratory can be made to be stable, so that a single bubble will expand and collapse over and over again in a periodic fashion, emitting a burst of light each time it collapses. For this to occur, a standing acoustic wave is set up within a liquid, and the bubble will sit at a pressure anti-node of the standing wave. The frequencies of resonance depend on the shape and size of the container in which the bubble is contained.

thanks for adding the synopsis, Emeraldhope.

Here's a link to the BBC article-http://www.bbc.co.uk/sn/tvradio/programmes/horizon/experiment_prog_summary.shtml

Rusi Taleyarkhan's belief that it was causing a fusion reaction...an independent lab was able to confirm this, which may or may not have been caused by equipment variables.

It's very interesting, even if not fusion. Definitely gonna have to look more into it. However, if it really is a fusion reaction, I'm sure it would get squashed by the PTB.

This is very interesting to me. One of our more recent projects at work is using a laser to cool a cloud of cesium atoms, holding them in place long enough to interrogate them for resonance, to make a very stable oscillator. I don't think they've considered using an acoustic standing-wave to hold the cloud in place. I'll have to bring this up to the guys at work :)

If they develop tech out of it, you gotta share the royalties with the forum! LOL!

yes, sonarluminescence is fascinating. i came across it recently in a documentary using high-speed cameras. they filmed the pistol-shrimp who creates a 'blast' by snapping his claw at great speed.

i'm sure the ancients with their sound 'technology' knew all about sonarluminescence and we're just rediscovering it.

now that's reminding me of Coral Castle...didn't that guy supposedly use sound waves to move the coral?

LOL, if only it worked that way...but lowbies such as myself make suggestions that get dismissed, after all, I have no Piled Higher and Deeper after my name, then the PTB retire to their closed-door meetings to discuss and implement the ideas, and voila, new product :) No money for me, LOL...but if they decide to use anything, I'll be sure to let you know :)

Have a look at what they have done with pulling on scotch tape in a vacuum. Reports state that this generates X-rays.
