I'd like to see the other way around. Use the sound to make heat.

Has anyone tried to combine thermoacoustics with RMS (Resonant Macrosonic Synthesis). Carefully choosing the shape of a resonator allows for larger sound amplitudes. Industrial applications like pumps, refrigerators, and compressors that use sound to do work can be developed with RMS. A bulb shape is one of the types of resonators that produce RMS. I wonder would that work with thermoacoustics to get greater efficiencies or horsepower?

Specifically, the second and third devices are "Sondhauss tubes" with steel wool (instead of a bundle of glass tubes) serving as a heat exchanger
-
The first device (the metal pipe) was a Rijke tube -- a heat-powered sound generator. (Lord Rayleigh explained how it works.) The pipe acted as a half-wave resonator.
The second device (the glass cylinder) was also (very likely) a Rijke tube. The cylinder acted as a quarter-wave resonator. The third device (the test tube) was just a smaller version of glass cylinder.

That happens all the time actually, when sound hits a surface it converts its energy partially to heat... Actually, most forms of energy can end up as heat, it's the other way round that's hard.

These can be LOUD. Don't leave the heater under the tube for too long.

Now that you've learning something about sound, why not learn about typography and HOW NOT PUT TEXT OVER BUSY BACKGROUND if you want your readers to be able to read it!!! I swear, you smart people have no @!(# damn creativity.
