Two-Stage Traveling Wave Engine

A two-stage thermoacoustic stirling engine made mostly of standard plumbing fittings. It has two heat exchanger and regenerator sets. It is heated by propane and cooled by a pool of water. The wave form gets a bit strange most likely due to reflections inside the engine. It has a lower start-up temperature than single-stage thermoacoustic stirling engines.

is it as simple as it looks or is there something clever inside? i have been trying to make a standing wave resonator for ages and i cant get the little bugger to work

@lendoggtheking Took me awhile too. What may be tough are the heat exchangers. I use copper wire 60 strand per inch mesh held in place by a ring of copper. The stack for a standing wave engine is looser than for a traveling wave engine (see some pyrex tube versions). Take a look at my other video, Inside a Thermoacoustic engine to see the exchangers. Other thing to worry about is thermal bridging across the exchangers. Only connection here is teflon tape.

Ghosts in the pipes hay.  I suppose this is what those ticks and squeaks are the the loonies say are ghosts;)
