pretty wicked cool.
This is the one that produces electricity along with the heat. Not the backpack model

I really love stirling engines. Even built a model that works. (barely)
And the thermoacoustic ones are genius on top of genius. I just hope this technology really matures and gets affordable.

Till then one can still have a small thermoelectric generator.
