Chena Hot Springs geothermal is a heat pump. It's an absorption chiller used partially (primarily?) to keep an ice house chilled as a tourist attraction. It works for such relatively low geothermal temperatures because the average Carnot Delta T is pretty good (because Alaska).
As to whether or not thermo-acoustic technology could work, that's a good question.
