@Bryan-Hensley And if it isn't something that can be made to work in the next few years, then there's not much point to it ever being developed.

It wouldn't be particularly practical, but if you lined the wall with piezo generators you could probably harvest some of the sound and generate some power out of it. I doubt enough with the speakers we have available, but probably some.

There's also the issue of needing helium to get it to work. With the shortages we're already having in helium, I'm not sure that a new technology that really requires it is such a good idea. I do sort of see the theory behind how this might work, but I don't see this one as being practical soon enough to be useful ever. It looks like the population of the world is about to start declining, which opens up opportunities to clean up the atmosphere and if conventional airconditioners are being driven by clean power, then it wouldn't much matter.
