Exploring Sonoluminescence : a discussion on "Simple" replication methods

[itsu]

A similar setup as used in the mentioned Spanish article (sorry, i don't speak Spanish) can be found here:
http://techmind.org/sl/#flask

I see some pictures from that article in earlier posts from Stivep, but no link to it.
It contains some very usefull info on the used flask, transducers etc. and how to set it up.


Sound in water (temp. dependent) is about 1480 m/s (20°C)   https://en.wikipedia.org/wiki/Speed_of_sound#/media/File:Speed_of_sound_in_water.svg
So at 25Khz a full wave spans 1480 / 25000 = 0.059m = 5.9cm what probably the diameter of the used flask should be.

Some nice explanation about this can be found here:

I will try to get the article translated tomorrow .

thanks for all the info !

there are many others reading here who are just seeing this for the first time and honestly

It is quite fascinating !

Chet
PS
also quite happy that more exotic experiments are on the menu !

[stivep]

for these who are still opt of 28kHz

The seller did not show spec or full view all around

Wesley:

Well you are too late de "Italian" discovery was killed by the dogmatic so called "scientists" in the USA just like cold fusion .. Science is now a dead horse.. with no real research anymore .. RIP discoveries ..

Acca...



Ps.

Polish great man is no more RIP the best scientist in LNER ..

Following Nature's Documents Stan Szpak and LENR Co-deposition HD is taken from interviews conducted January, 2015 with former Navy scientists and engineers Dr. Stanislaw Szpak, Dr. Frank Gordon, and Dr. Melvin Miles, who each researched the anomalous effects in deuterated systems. They collaborated on co-deposition experiments, among other things. Co-deposition was a reproducible method of initiating excess heat, tritium production, low intensity radiation, morphology changes on the surface from electric and magnetic fields, hot spots and mini-volcanoes, as well as transmutations, in a cold fusion environment. Co-deposition became the basis of Navy SPAWAR LENR research until their program ended in 2011.
