    Link: Sonarluminescence - A Star In A Jar! - Sonoluminescence occurs when a sound wave of sufficient intensity induces a gaseous cavity within a liquid to collapse

    They never said what the liquid is. If it`s something common it could power all kinds of things -- like automobiles. Let alone the potential space travel and weapon uses.

    They`ve been exploring similar techniques for sonar scalpels for a while now, too. They have just recently managed to get the focal point of the scalpel accurate and stable enough for it to really have broad surgical applications. Neat stuff.

    other experiments on youtube say they use DI water.

    So, nuclear fusion ey?

    People have been arguing over whether it`s possible ever since sonoluminescence was first discovered. Probably not - the temperature and pressure is probably much too low. You`d need tens of millions of degrees in the centre of the bubble (depending on what the pressure is, but even the mind-boggling pressure of the interior of the sun only drops the required temperature to about 15 million). Ten thousand on the outside of the bubble and tens of millions millimetres away in the middle? Dubious.

    But it hasn`t been *proven* impossible.

    Yes, but I`m not sure about the intensity.

    This is cold fission, no?
    Or at least as close to it.

    I must have one of these! Even if it didn`t cause cold fusion, it would look good the coffee table.

    The title and the description do not match up. I think the title needs to be changed to "Sonoluminescence"

    Not cold fusion. This requires a ridiculous amount more energy put into the system than it delivers. Pistol shrimp do this. They don`t even know if they can put enough energy in it to cause fusion. So not even is it cold fusion they don`t even know if they can create fusion.

    This is from the BBC show "Horizon." Here is the full episode

    Spoiler alert: It`s not fusion, or at least hasn`t been proven to be yet.

    Even if it doesn`t give us fusion, it`s at least something that could show up as a novelty lamp.

    I love weird phenomena like this and triboluminescence (the effect you get when you peel re-sealable envelopes or crack Wint-O-Green mints in the dark, and you see light flashes as the chemical bonds break down and release the energy that formed them as photons). It makes you realise that we`re living in a world made of some pretty weird stuff at a subatomic level, that nobody really understands yet. Like a big macroscopic simulation based on a deeper reality. Must sell that script idea.......what do you mean it`s already been done!?

    "Mmmm science:Lost count Religion:-1000

    Using sound to create a light producing reaction? Where have I heard that before? Oh yeah...

    And God said, "Let there be light," and there was light.

    That`s not entirely fair. The effect of religion wasn`t entirely negative. In "the west", a lot of the preservation of literacy and ancient knowledge was down to religion. It was true to such an extent that in many areas for centuries being able to read and write was considered adequate legal evidence of being a member of the clergy (which conferred significant legal privileges - "benefit of clergy"). As a result, the continued existence of some ancient works of knowledge was due to religion - it was clerics who were copying and recopying the ancient documents.
