Fusion In Sonoluminescence (Again)?

srhuston writes "According to a story at the NY Times (first born child req'd, yadda yadda), 'Scientists are again claiming they have made a Sun in a jar, offering perhaps a revolutionary energy source, and this time even some skeptics find the evidence intriguing enough to call for a closer look.' This has been covered here before (First, second, third) but it looks like they claim that the latest round of experiments, using better detectors, 'offer more convincing data that the phenomenon is real'." The scientists involved come from Rensselaer Polytechnic Institute, Purdue University, Oak Ridge National Laboratory, and the Russian Academy of Science; here's their press release.

      It's a simple typo, you insensitive clod. He meant "dieting." See, unlimited free energy implies life extension, and if you're going to live for a thousand years, you'd want to look GOOD!

      Or maybe he meant "dining" - you know, joining together in a celebratory feast. I guess that would mean they already look good and don't have to worry about it?

      It's possible he meant "dicing" - either chopping up meat for their dinner, or chopping up celery for their diet. Or maybe rolling a d20 (Save vs Poison or take 10d6 of damage from radiation.)

      Hypothetically, the word could be "diving" but that would obviously be ridiculous.

    From the HOWTO:
    Equipment (required):

    * sinus generator:
    any function generator working around 25 kHz, adjustable to +/- 1 Hz (+/- 10 Hz may work, too)
    * amplifier:
    nearly any kind of audio amplifier will do. If you're not sure, measure the saturation voltage: 40 V peak-to-peak should be enough.
    * 2-trace oscilloscope
    * 2 piezoceramic Transducers (drivers):
    around d=16 mm in diameter, h=8 mm thick
    * piezoceramic pill-transducer (microphone):
    around 3 mm in diameter, 1 mm thick
    * three finger clamp
    * laboratory stand
    * flask:
    take a 100 ml Pyrex/Duran spherical flask, diameter 65 mm, with a small neck. An industrial one has poor optical quality, so better take a free blown one.
    * coil(s): around 20 mH, see text
    * resistors: 1M, 10k, 1R
    * coaxial cable
    * quick-drying epoxy glue
    * an eyedropper or a syringe (one of those little do-it-yourself subcutaneous is very good)
    * degassed distilled water:
    o Pyrex/Duran Erlenmeyer flask (0.5 or 1 l) and airtight stopper with pipe, rubber hose and clamp to close it
    or
    o aluminium/highgrade steel drinking bottle (0.5 or 1 l) with screw cap; one of those found in camping stores, a bare one without varnish
    * a bubble ;-)
