The noise generated by the usual combustion instabilities of forced draught burners is annoying and requires hearing protection if working nearby, this takes that to a new level. Structural integrity of the burner refractory might be an issue.
Sonic atomisation of liquid fuels has been used before and some WWII sound weapons used resonant combustion as a noise source.
wtf, how about any data on BTU's or unburnt hydrocarbons. because it actually looks like it's not getting an improved combustion A) because i gas torch like that is getting very near complete anyway B) the flame get's significantly smaller with out any visible rise in color temperature, actually looks colder. Maybe try a very carbonaceous fuel and see if it improves it, but as far as a gas torch is concerned, not gonna improve it
Blow into a torch/bunsen burner, it looks like that too; put it in a resonator, OK, it can make noise. However, the whole "cleaner burning" bit is a total fabrication.
@poepflater Jets fly though the atmosphere, not space. Rockets don't need air for propulsion (they carry their own oxygen) or control (they use thrusters to point them wherever)
Lower a pulse jet into a 44 gallon drum.A vacume cleaner on the small hole and it will resonate.But if you put the vac,clen, strate onto the tale pipe nothing will happen
I don't know if you knew this but the exact same resonance occurs when the torch is placed inside the intake (smaller and shorter) tube of a pulse jet engine. I had tried this on mine and the air flow that is generated is pretty impressive.
It's useful to know because such resonance can kill a rocket engine, and endanger crew and equipment. In fact, several accidents in space travel owes their cause to such resonance.

Actually, some types of Pyrex can be used as a crucible to melt steel. Some borosilicate glasses melt at unbelievable temperatures. I'd make the tube from a molybdinum alloy. Higher heat tolerance, rather than melting point.
I would assume so. Just need to place a black object inside onto which you would concentrate the suns light. What the video here shows is suited to making better burners for use in the home and industry. Better flame sources for all sorts of uses. Using sonic resonance is already used to make a better cooling system. Why not a more efficient heati transfer flame generator?
well, in this video, it's useful for torch welding without introducing contaminants into the weld pool. but for a car? no. the combustions in a car engine are all entirely separated, thus they cannot resonate with one another as opposed to a pulsejet-type setup.
@puredihydrogenoxide it might, due to better mixing from the resonating causing turbulence. would be such a great theory to exploit if not for some of the instabilities involved. i might be outdated though :D
@puredihydrogenoxide when he puts the flame deeper into the glass thing (I don't know what) see how the flame gets smaller? Its a cleaner burn so yes it could be usefull.

p.s. space is not a complete vacuum, else even jets would not be able to move.

it`s not the flame that makes this resonation, it`s the backstreaming air, need for the burning process

The exhaust gases are enough of a medium for sound to resonate within a rocket.

do not use glass. It will melt and break down after 5 minutes. Try some tube from steel or tungsten.
