Although it's an old discovery some scientific authors and even general bloggers and publishers are releasing more data and perspectives on the Sonoluminescence effect. This was first discovered at the University of Cologne in 1934 during work related to sonar technologies.

H. Frenzel and H. Schultes put an ultrasound transducer in a tank of photographic developer fluid. They were doing this in the hope that is would speed up the development process. Instead, they noticed tiny dots on the film after developing and realized that the bubbles in the fluid were emitting light with the ultrasound turned on. At the time It was too difficult to analyze the effect in early experiments because of the complex environment of a large number of short-lived bubbles. A new acronym was later used to refer to the effect as MBSL (MULTI-BUBBLE SONOLUMINESCENCE).

Years later In 1960, Dr. Peter Jarman from the Imperial College of London proposed the most reliable theory of the Sonoluminescence phenomenon. The collapsing bubble generates an imploding shock wave that compresses and heats the gas at the center of the bubble to extremely high temperatures. This wasn't proven until later in 1989 when D. Felipe Gaitan and Lawrence Crum, who produced stable single-bubble sonoluminescence (SBSL)., a single bubble trapped in an acoustic standing wave emits a pulse of light with each compression of the bubble within the standing wave.

This technique allowed a more practical study of the phenomenon because it isolated the complex effects into one stable, predictable bubble. It was realized that the temperature inside the bubble was hot enough to melt steel, as seen in an experiment done in 2012, below is a video related to this

The temperature inside the bubble as it collapsed reached about 12,000 kelvins. Interest in sonoluminescence was renewed when an inner temperature of such a bubble well above one million kelvins was postulated. This temperature is thus far not conclusively proven; however recent experiments conducted by the University of Illinois at Urbana–Champaign indicate temperatures around 20,000 K (19,700 °C; 35,500 °F)

We will be adding more on this later and how it might be used to high energy efficiency without the need for fossil fuels industry energy technologies. The fact we are even still using fossil fules for energy tech at all is a sure sign that rich oil companies really dont want to let go of the power game thay have. we will explian more soon hang tight!
