How can I build an efficient thermoacoustic device with household materials? Answered
For a while now, I have been trying to build a thermoacoustic device with the following specs:
-Can run with a temperature difference at around 100 degrees Celsius (ice on one end, boiling water on the other end, but it won't actually work with water)
-uses normal air for the working fluid
-constructed out of available household materials (or anything I can find at a hardware, office, or similar store)
I have tried jamming coffee stirrers in a PVC pipe with copper wire serving as the heat sink, alternating layers of foil and two-sided tape, and for the third & recent attempt, newspaper jammed between two peg-boards (untested, but unlikely to work).
