Thermoacoustic Stirling Engine

This is a thermoacoustic Stirling engine. It makes sound when heat is added to it from any source. This engine also has a piezoelectric alternator which converts the sound to electric and runs the LEDs. It's a small-scale demonstrator.

this is basically a fire alert which alerts "TOO LATE" :D

@vanzonhl LOL exactly! Don't know why the comment was deleted. That wasn't me.

how would you use thois?

[Stirlingsound]

@cleric022684 This engine is just a small demonstrator to show that one can make such an engine that produces power. A practical engine could be of similar size or a bit larger but would require the air it contains to be pressurized. This design would need to be modified and built of suitable materials (stainless steel) in order to do this. Such an engine might be a good portable power source useful to charge electronics using local biomass in a small woodgas stove.

Is the stack made in pin or sheet form?

[Stirlingsound]

@mikerushford The stack is random orientated fibers since it is 0000 steel wool, the kind you get at any hardware store. Wish I could give you an accurate number for the density. Roughly cut a 1 cm thick disc as it comes in the package then compress to about 1 mm.

Thats so fast I could hardly see it move.

@Stirlingsound : i think i deleted the first try myself, there was a typo :)

[bakothegreat]

@Stirlingsound Its ineffecient.
